Benoot, Nicolas. "Self-assembly of hybrid microgels for interferential and responsive photonic applications." Electronic Thesis or Diss., Pau, 2020. http://www.theses.fr/2020PAUU3047.
Повний текст джерелаIn the world of cosmetics and skin care products, there is a real need for innovation to find new materials with no impact on the consumer and the environment. In a bio-inspired approach, so-called "physical" colors offer a new way of creating colors without inorganic pigments. Indeed, today mineral pigments are the main source of coloring for cosmetic applications and their replacement represents a critical issue to limit possible exposure to potential nanoparticles.Sensitive to this challenge, LVMH Research worked with IPREM to design a solution resulting from the self-assembly of micro-hydrogels, known as microgels, with multiple stimulable properties, to produce color without pigments.These microgels, dispersed in water, have the capacity to spontaneously organize themselves during the evaporation of the solvent to produce very regular assemblies. These periodic assemblages, assimilated to "colloidal crystals", interfere with visible light and can lead to diffraction phenomena. The diffraction of visible light by the colloidal crystals leads to a so-called "physical" coloration.The work of this thesis project focuses on the design of hybrid microgels to enhance its photonic properties and lead to the formation of films after drying whose colors can be modified by a stimulus. The manuscript first presents the scientific context in which this work is carried out before discussing the synthesis process undertaken. In a second step, the photonic and stimulable properties are discussed in relation to the 3D organization of microgels within the film. Finally, efforts to transpose this technology into a cosmetic formulation are presented

This qualitative case study focused on a Response to Intervention (RTI) literacy initiative in a suburban elementary school near an urban area in New England. The initiative incorporated professional development about RTI and implementation of components of an RTI model. The participant-researcher analyzed teachers' feedback regarding the professional development and the RTI model, as the initiative developed, with a specific focus on the teachers' perceptions about the impact of the initiative on the school's capacity to effectively instruct urban students of color who are participants in a voluntary desegregation program. The professional development about RTI incorporated three features which are recommended for professional learning communities: content which is research-based, process which includes reflection and dialogue, and context which is job-embedded. The RTI model utilized the "problem-solving" approach, and incorporated progress-monitoring and interventions. The findings from the study indicated that the combination of three elements (sustained professional development about RTI, implementation of RTI in the school setting, and conversations and questions about addressing the needs of urban students of color) resulted in increased teacher confidence in their ability to provide effective instruction to this population of students. Further, the interaction of these three elements resulted in identification of next steps which the teachers believe will specifically address these students' needs. However, several teachers questioned whether RTI was adequate to address the complex issues of students of color in a voluntary desegregation program. They recognized that they needed more information about effective instructional strategies to match the learning profiles of this population of students. Combining the results of this case study with the recommendations of the professional literature about culturally responsive teaching, it appears that Response to Intervention has the potential to address the learning needs of urban students of color, but only if practitioners incorporate some basic principles of culturally responsive teaching. Integrating the results of this study with the professional literature about Response to Intervention, culturally responsive teaching, and effective professional development, the participant-researcher recommends that policymakers and educators should consider incorporating culturally responsive teaching into their RTI models in order to truly make RTI effective for addressing the achievement gap. Further, the researcher recommends that schools should provide sustained professional development (with content based upon research, process which includes reflection and dialogue, and context which is job-embedded) to increase teachers' understanding about Response to Intervention and about culturally responsive teaching

Our current global health crisis has clearly rendered how a lack of stable housing, access to care, and the effects of climate change, disproportionately affect our communities of color. Contemporary development patterns demonstrate the inadequacies of unchecked neoliberalism, and its adverse effect on the development of equitable housing. Within this context, Miami presents itself as a vulnerable coastal city exemplar. A growing city, Miami struggles with an endemic affordability crisis, and the long lasting scars of segregation, redlining, and urban renewal in its most vulnerable communities. Today, the city's muddled past has been compounded with its uncertain future. Despite palpable climate change, construction continues along the Miami waterfront, fueled by foreign investors who park capital in luxury real estate. For local residents, both low and mid income, the cost of living continues to rise along with sea levels. Miami, outwardly marketed as a tropical oasis, is now regarded as one of the country's most inequitable cities. This thesis takes issue with the commodification of housing, and its adverse effects on the vulnerable communities of greater Miami. While Miami's surplus of luxury real estate swells, climate change and speculative development have combined to threaten the stability of the city's multi-ethnic core. Instead, it re-considers the cooperative, and the collective ownership of housing, as a mechanism by which communities can reclaim agency within hostile markets, and open up access to stabilize housing in response to climate gentrification, as well as opening up access to other forms of social and financial capital. It works to re-contextualize the cooperative ownership of housing within the Miami context, considering its deployment as an architectural response who's programming and spatial organizations respond to both collective use and collective need.

Повний текст джерелаBiofilm device-related infections can lead to antibiotic failure requiring frequent removal of medical device. Pseudomonas aeruginosa has emerged as the typical pathogen for biofilm infections. To explore the determinants of antibiotic failure in biofilm, an in vitro P. aeruginosa biofilm model exposed to suprainhibitory antibiotic concentrations was developed. In planktonic culture, the ciprofloxacin and amikacin combination prevented the selection of resistant mutants in ciprofloxacin and amikacinlow-level resistant P. aeruginosa strains overexpressing efflux. In biofilm, the ciprofloxacin and amikacin combination, used simultaneously or sequentially, didn’t show superior effects compared to monotherapies. Despite an initial bacterial reduction, biofilm eradication was not obtained. Regardless of wild-type or efflux strains and antibiotic regimen used, antibiotic failure was related to the selection of antibiotic-tolerant cells named “persisters”. Ciprofloxacin induced significant alterations in the biofilm structure, notably a considerable reduction in the exopolysaccharides of the matrix. The transcriptomic analysis of genes, potentially involved in persistence, suggested that early activation of the stringent response might be one of the main pathways for ciprofloxacin tolerance in biofilm. Finally, the emergence of "small colony variants" within the biofilm, characterized by enhanced ability to form biofilm, attested to biofilm heterogeneity. This work therefore contributes to a better understanding of how P. aeruginosa biofilms escape antibiotic

Повний текст джерелаByggnadsautomationsbranschen saknar en kostnadseffektiv lösning för att autonomt trimma in PID-regulatorer när överordnade variabler fluktuerar. I detta (av Jitea AB beställda) arbete, utvecklades en lösning baserad på stegsvarsmodellering, numerisk integration av första gradens ordinära differentialekvationer och myrkolonisoptimering (ACO). Lösningen applicerades i två regleringsfall; en simulerad utloppsventil från en virtuell vattentank, och det fysiska lufttrycket i ventilationssystemet på en förskola i Sverige. Ett stegsvar med öppen slinga gav en överföringsfunktion i respektive fall, som efter viss manipulering kunde nyttjas för att förutspå prestandan för en uppsättning PID-parametrar baserat på en samlad, viktad kostnadsfunktion. Predikteringsmodellen implementerades i ACO för att finna optimala parametrar. Programmet konstruerades i Structured Control Language och Structured Text, och dokumenterades på ett pedagogiskt sätt. Resultaten visade att programmet (i båda fallen) klarade att eliminera översläng med bibehållen stabiliseringstid (och något förskjuten stigningstid) jämfört med Jitea AB:s existerande trimningsmetod. Signalbrus och oscillationer i det fysiska systemet verkade inte ha någon avsevärd negativ inverkan på trimningsprocessen. Programmet presterade över Jitea AB:s förväntan, och kommer (med tanke på de lovande resultaten) fortsatt att testas i fler scenarion. Implementation av en autonom version skulle kunna innebära flera samhälleliga förmåner i form av ökad verkningsgrad och hållbarhet i en rad processer. I framtida studier bör fokus läggas på att ytterligare förbättra prediktionsmodellen, samt att vidare utforska de optimala myrkolonisvariablerna.

Anthocyanins are natural colorants that provide attractive and bright colors to most plants, coloring them the bright red to violet. Due to its instability facing the food processing steps and their difficulty of extraction are still little used in the food industry. Flavonoids not anthocyanins, amino acids, nucleosides, organic acids and anthocyanins themselves may act as copigments enabling the anthocyanins as natural colorants. The objective was to evaluate the approximate composition, phenolic compounds, antioxidant activity of blackberries Brazo (Morus nigra L.) and the stability of anthocyanins. The effect of the addition of organic acids and polyphenolic extract of Camellia sinensis raw extract of blackberries anthocyanins as copigments. The copigmentation reaction buffer at pH 3.0, was confirmed by UV-Visible absorption and by high high-performance liquid chromatography analysis. The calculated half-life and the color retention percentage. The response surface methodology was effective to estimate the effect of three independent variables on anthocyanins extraction, the optimal values suggested for the extraction with citric acid were time of 60 min., ratio of 1 g / 30 mL and a temperature of 60 ºC and the extraction with hydrochloric acid have been suggested the same conditions of time and ratio, but at 20 ° C. The increase in relation copigmento / anthocyanins was evidenced by the bathochromic and hyperchromic effects. The interaction of anthocyanins was significantly affected by temperature (5 ± 3 ° C and 25 ± 3 ° C) and the environment (light and dark). The stability of anthocyanins with added copigmento increased half-life and the color retention percentage of sample. Maximum stability was achieved in samples with the addition of caffeic acid at a temperature of 5 ° C ± 3 ° C in the dark. Anthocyanins added caffeic acid and malic showed half-life of 242.40 ± 25.40 and 200.48 ± 12.15 days, respectively, bringing prospects for application of this natural dye.
Antocianinas são corantes naturais que proporcionam cores atrativas e brilhantes à maioria das plantas, colorindo-as do vermelho vivo ao violeta. Devido à sua instabilidade frente às etapas de processamento de alimentos e a sua dificuldade de extração ainda são pouco utilizados na indústria alimentícia. Flavonóides não antociânicos, aminoácidos, nucleosídios, ácidos orgânicos e as próprias antocianinas podem agir como copigmentos viabilizando as antocianinas como corantes naturais. O objetivo do trabalho foi avaliar a composição aproximada, os compostos fenólicos totais, a atividade antioxidante de amoras Brazo (Morus nigra L.) e a estabilidade das suas antocianinas. Foi avaliado o efeito da adição dos ácidos orgânicos e extrato polifenólico de Camellia sinensis ao extrato bruto de antocianinas de amora como copigmentos. A reação de copigmentação em solução tampão pH 3,0, foi confirmada por espectrofotometria de absorção UV-Visível e por análise cromatográfica líquida de alta eficiência. Calculou-se o tempo de meia vida e a percentagem de retenção de cor. A metodologia de superfície de resposta foi eficaz para estimar o efeito de três variáveis independentes sobre a extração de antocianinas, os ótimos valores sugeridos para a extração com ácido cítrico foram tempo de 60 min., razão de 1g / 30 mL e uma temperatura de 60°C e para a extração com ácido clorídrico foram sugeridas as mesmas condições de tempo e razão, porém a uma temperatura de 20°C. O aumento na relação copigmento/antocianinas foi evidenciado pelos efeitos batocrômico e hipercrômico. A interação das antocianinas foi significativamente afetada pela temperatura (5±3ºC e 25±3ºC) e o ambiente (luz e escuro). A estabilidade das antocianinas com adição de copigmento aumentou o tempo de meia vida e a porcentagem de retenção de cor das amostras. A estabilidade máxima foi alcançada nas amostras com adição de ácido cafeico em temperatura de 5ºC±3°C e no escuro. As antocianinas adicionadas de ácido cafeico e málico apresentaram tempo de meia vida de 242,40 ± 25,40 e 200,48 ± 12,15 dias, respectivamente, trazendo perspectivas para aplicação deste corante natural.

Повний текст джерелаIntravenous administration of Hypertonic saline solution (HSS) induces systemic circulatory changes including blood pressure rising, effective circulating volume increase as well as local effects on microvasculature. We analyzed the effects produced by Hypertonic Saline 7,5% administration on tumor hemodynamics through functional imaging studies as well as whether it enhances molecular delivery in tumor tissue when used as a vehicle. Blood velocity assessed by Color Doppler Ultrasound was increased after HSS injection compared to PBS in the following tumors: B16F10 (p=0,019), SKMEL- 147 (p=0,028) and 4T1 (p=0,015). No statistical difference was observed on the segmental kidney arteries (p=0,476). Dynamic Contrast enhanced ultrasound (CEUS) was done in B16F10, HCT-116 and MDA-MB-231 tumor xenografts, kidney and muscle tissues (n=3 per group). After HSS injection, relative blood volume was increased in B16F10 (p=0,022) and HCT-116 (p=0,039) but not on MDA-MB-231 (p=0,186). Changes on normal tissues were not statistically different (kidney p=0,957; muscle p=0,104). All statistical tests were two-sided. Administration of HSS as a vehicle for low molecular weight molecules cisplatin and doxorubicin in the treatment of B16F10 and 4T1 tumors respectively had no significant improvement of therapeutic efficacy, estimated by tumor growth and tumor weight measurements. Effect of HSS over retention of macromolecules in tumors SK-Mel-147 and 4T1, evaluated by epifluorescence imaging of the optical contrast IR- 783 was not large enough to reject the null hypothesis. HSS induces a transient increase in velocity of the blood as well as the blood volume that is relatively selective for the evaluated tumors with exception of MDA-MB-231. Data suggest that HSS administration might be a useful strategy to increase the delivery of molecules and optimize both therapy and diagnostic imaging

Повний текст джерелаThe trained athlete is a physiological model of extreme cardiac adaptation for whom the distinction between adaptive cardiac remodeling induced by chronic exercise and certain early cardiomyopathies can be difficult to assess. Echocardiography is the first-choice imaging modality to evaluate the athlete’s heart at rest and during exercise. Semi-recent developments in speckle tracking and 3D ultrasound imaging have shown clinical interest in the echocardiographic description of the athlete’s heart. However, some technical aspects require further investigation. Moreover, current post-treatment tools provide only a partial analysis of cardiac hemodynamics and regional myocardial function. Using an experimental model mimicking stress echocardiography, we first demonstrated the validity of speckle tracking in comparison to sonomicrometry to measure regional deformation in a large range of deformation rates. Secondly, we studied in volunteers without heart disease (athletes and non- athletes) the reliability of a method to assess non-invasively the left ventricular (LV) systolic and diastolic intraventricular pressure gradients (IVPGs) based on post-processing of intracardiac flow velocity data acquired using color Doppler M-mode. This hemodynamic index was highly feasible and well correlated with LV suction. Analysis of IVPG measurements revealed inter-vendor variability which was mainly related to differences in color Doppler image resolution. Finally, using a multiparametric echocardiographic approach (speckle tracking, IVPGs, and 3D volumes), we studied the physiological relationship between the type of exercise training and the left and right cardiac remodeling among a Canadian football team followed longitudinally. The regional analysis of right ventricular (RV) morphological and functional changes induced by chronic exercise was performed using a new computational method based on 3D echocardiography that volumetrically parcellated the RV into three segments (apex, outlet, and inlet). In conclusion, our workhas shown that the echocardiographic post-processing tools studied for the global and regional analysis of cardiac function and morphology apply to the athlete’s heart and could be useful in the characterization of the exercise-induced cardiac remodeling

Spatial receptive fields have been studied to understand the properties of color- and luminance-responsive neurons in primary visual cortex (V1). In macaque V1, many color-responsive neurons are highly selective for orientation and spatial frequency. One might predict that these highly selective neurons should have receptive fields with multiple and elongated sub-regions (like simple cells). However, previous studies showed that this was not the case — many sharply tuned neurons had blub-like and less elongated receptive fields. Here we measured spatial receptive fields of V1 color-responsive neurons with two different stimulus ensembles: Hartley gratings and binary sparse noise. Both stimulus ensembles consisted of equiluminance red/green colors. Receptive fields were calculated by reverse correlation and fitted with the 2-D Gabor function. Color-responsive neurons were separated into double- and single-opponent cells based on their spatial frequency tunings. We found that double-opponent cells had significantly higher aspect ratios and spatial frequencies than single-opponent cells. The agreements between receptive field properties and orientation tunings were established only in Hartley grating condition but not in sparse noise condition. Double-opponent cells were also found to have lower modulation ratios. Furthermore, most color-responsive cells had red-preferring receptive fields. In summary, double- and single-opponent cells differed in their receptive field properties. For those neurons that were well tuned for orientation and spatial frequency, the tuning properties could be well predicted by Hartley maps but not sparse-noise maps. Our results supported the idea that double-opponent cells might serve as detectors of color edge in the equiluminance scene.

The color correction of color gamut can be accomplished directly by matrix operations. Linear matrix transforms may be regarded as recom- binations of the spectral responses of the scanners. Common scanners usually process color signals via three filters corresponding to the three tristimulus values. Thereby, a 3 by 3 matrix representing the color correction function is needed for the scanners. If higher order polynomials are used, a 3 by P matrix is needed, where P designates the number of the terms of the polynomials. When we use the higher or- der polynomials, we would find that recombinations of the spectral re- sponses of the filters of the scanners are highly correlated with the samples. In other words, the samples affect not only the proportions of the recombinations of the spectral responses of the filters, but also how these spectral responses combine. This thesis compares linear combination with higher order polynomials.

The color, shape and size are main factors to people to define an object in daily life.The color of an object depends on both the physics of the object in its environment and the characteristics of the perceiving eye and brain. The colors result from neural responses in human’s visual neural systems, whose process and activities can be understood through human electroencephalogram (EEG). In terms of patterns, human perception of colors is influenced by patterns and sizes; patterns, colors and sizes bear close relations and interact with each other. Therefore, this study explored the reaction of EEG to visual stimuli aroused when people perceive combinations of different colors,patterns and sizes. The study results indicated that: (1) Different colors (R, G, B), different patterns (checkerboard, horizontal stripes, and concentric circles) and different size has significant effects on four peaks of EEG (N1、N2 latency and P1、P2 amplitude).(2) There has significant differences in EEG with higher P2 amplitude response of checkerboard and horizontal stripes by red color than the other two colors (checkerboard: red > blue > green; horizontal stripes: red > green > blue); for concentric circles, there was higher P2 amplitude response by blue color than green, the lowest was red color (blue > green> red).

Recently, LCDs have become the most popular display devices because of their low power consumption and compact size. LCD applications are widely used in many aspects, such as LCD TVs, PC monitors, and mobile phones. But to replace traditional CRT displays, there are still some questions should be solved. In this paper, we purposed novel algorithms for the adjustment of LCD color characteristic and gray level response time. By connecting the hardware, the colorimeter and photo sensor, the color characteristics and response time can be measured quickly. Measurement data is used for the analysis in the algorithm, and after the analysis, the new LUTs are derived. Users can set related parameters on the user interface developed by visual basic in the windows environment. According to these settings, the LCD panel used for this experiment can be automatically adjusted. The experimental result would be the best method to determine whether the algorithm is correct or not. After our adjustment, the correlated color temperature can be roughly equal to the target color temperature and the average gray level response time is also under the target response time.

Quantum wells Infrared photodetector have been widely used in many fields, such as astronomy, medical, construction, military, security systems and etc. In our study, superlattice structure is added in order to enhance light absorption efficiency. Grating structure can also improve responsivity. The effect of grating system not only can concentrate light energy and then improve the photocurrent, but also can greatly increase its absorption in the active layer. Superlattice structure can help electrons easily excited by photons, which make our device can be operated at low bias voltage. Due to the small resistance, the dark current can be effectively reduced and then reduce the noise generation. Another study is to enhance responsivity of the photo detector by changing grating depth. We find that as the period of grating structure is fixed at 2μm, the relationship between the grating depth and the responsivity is not an increasing function. According to the results, the optimal value of the responsivity is detected when the grating depth is 1.3 μm. Compared with the devices without the grating structure, our best device had 2.5 times of the gain. The maximum operation temperature of our best device is measured at 83K.

There is a tendency towards colorized Thin Film Transistor Liquid Crystal Display (TFT-LCD) undoubtedly. The color filter, which contains three fundamental colors of red, green, and blue, is an important and essential raw material for TFT-LCD. One panel of TFT-LCD is assembled by a pair of the same size of TFT Array and color filter, therefore, color filter with good quality is very important, it is significant influence to the performance of TFT-LCD. In the process of TFT-LCD assembly, the supports between thin film transistor and color filter substrate depend on the uniform distribution of spacer, it also keeps the gap between thin film transistor and color filter for injection liquid crystal. The content of photo spacer is photosensitive resin, photo spacer size and photo spacer precision can be controlled since it is manufactured by the mature photolithography process on the black matrix of color filter, one of the advantages of photo spacer is to prevent moving of bead type spacer to keep the good uniformity of cell gap, it also prevents light leakage around the spacer to get higher contrast. This research focuses on the problem of photo spacer process of color filter and builds two steps Design of Experiment method model. The first step is considering the all factors that will inference photo spacer process, apply the factional factorial experiment method to find out the critical factors. The second step applies Response Surface Methodology with Central Composite Design, the purpose is to find the optimum parameters setting and suitable process operation range to ensure process index capability.

Two experiments were conducted to investigate the effects of color combination on subjective preference, glance legibility and EEG response of symbols. The first experiment evaluated subjective preference of target/background color combinations of the symbols. The result showed that white was rated greaten than other colors. The more preferable color combinations were black/white, white/blue and red/white. while red/purple and white/yellow was less preferable. A significantly positive correlations (r = 0.57). was found between subjective preference and color difference of color combinations. The second experiment investigated the effects of color combinations on glance legibility and EEG response. The results showed: 1.The color combinations of greaten subjective preference had better glance legibility . 2.The latency of P100 for color combinations of greaten subjective preference was faster than those of less subjective preference. 3.The mean amplitude of P300 was larger when the duration of stimulant presentation was shorter. The result of this study showed that color combinations had significant effects on glance legibility, subjective preference and EEG.

The purpose of this study was to explore the influence of color temperature and illumination toward the user''s emotional responses of lighting facilities on urban park. The Ta-An Park and the Youth Park were chosen as the research sites about different color temperature, while two similar spots in these two parks were selected to compare the effect of different illumination under the control of color temperature. Data was collected by field-interview. Not only the respondents'' emotional responses were examined with the adjective pair, but also examined the relationship between factors of lighting and users. Statistic methods were factor analysis and one-way ANOVA. The main results are summarized as follow: 1.The results of factor analysis and one-way ANOVA toward color temperature under the emotional responses structure of "boredom-dull", "gloomy-cold", "surprised-active", "ugly-disordered" indicated significant difference. 2.Under two environments of color temperature, the results of one-way ANOVA toward four types of emotional responses respectively were: to the "boredom-dull" response, the average evaluation of Ta-An Park was negative while Youth Park was positive, to the "gloomy-cold" response, the average evaluation of Ta-An Park was negative while Youth Park was positive; to the "surprised-active" response, the average evaluation of Ta-An Park was positive while Youth Park was negative; to the "ugly-disordered" response, the average evaluation of Ta-An Park was positive while Youth Park was negative. 3.The results of factor analysis and one-way ANOVA toward different illumination under the emotional responses structure of "boredom-dull", "gloomy-cold", "surprised-active", "ugly-disordered" indicated significant difference. 4.The relationship between high and low illumination under four types of emotional responses above-mentioned in Ta-An Park was that different illumination leads to significantly different emotional responses within "surprised-active" and "ugly-disordered", it means different illumination will influence the emotional responses of "surprised-active" and "ugly-disordered" under warm color temperature. And in Youth Park, the significant different between high and low illumination happened within the emotional responses of "ugly-disordered" and "boredom-dull", it means different illumination will influence the emotional responses of "ugly-disordered" and "boredom-dull" under cold color temperature. 5.The analysis about the attitudes of users with different social-economic backgrounds toward the factors of lighting environment showed no significant difference under the conditions of sex, age, and occupation. But the users with different educational level possessed significantly difference attitudes toward the brightness, styles of lantern, light color, and background settings of lighting environment.

Web survey has been widely used for academic research, market survey, etc. Therefore, how to improve the efficiency and performance on questionnaires becomes an important issue. This research is to find out how it impacts the answering time, response rate, and user experience when we add colors on the survey page. To examine the effect of color, two experiments of online survey had been conducted, the first experiment added the color on the option of the questions, and the second one added color on the keyword and the options of the questions. These surveys had recorded the answering time and response rate of the subject, and the user experience by user experience questionnaire(UEQ) was also measured. The results show that the use of color on survey page has no significant differences with answering time and response rate. However, there are some scales of user experience have significant differences with the use of color on survey page.

In the study, we fabricated a fluorescence resonance energy transfer (FRET)–based electrospun (ES) nanofibers that possess dual color ratiometric fluorescence emissions for Fe3+ ions and pH sensing from the responsive fluorescent random copolymers blends, poly(HEMA-co-NMA-co-NBD)/SRhBOH, and investigated the efficiency of different probe content on the probing sensitivity of Fe3+ ions and pH. A Rhodamine derivative of Fe3+-recognizing fluorescent probe (SRhBOH) (acceptor) and green fluorescence emission monomer (NBDOMA) (donor) were synthesized at first. The fluorescence emission of SRhBOH is highly based on both of pH-dependent and Fe3+-detected solutions, i.e, non-fluorescence emission in neutral media or without Fe3+ ions (spirolactam form), but highly fluorescence emission in acidic or the presence of Fe3+ ions (ring-opened acyclic form). The ES nanofibers were prepared from the responsive fluorescent copolymer blends, poly(HEMA-co-NMA-co-NBD) blending rhodamine B derivative (SRhBOH). The copolymers were synthesized via free radical polymerization of initiator 2,2′-azobis(2-methylpropionitrile) (AIBN), hydrophilic 2-hydroxyethyl methacrylate (HEMA), cross-linked N-methylolacrylamide (NMA) and green fluorescence emission monomer (NBDOMA) (donor). Thus the on/off switching of FRET process can be modulated by solution pH and Fe3+ ions. The results indicate that multifunctional ES nanofibers with a high sensitivity toward pH and metal-ion for environmental sensory devices.
