Abstract:

The Ni-Me-P alloy coatings containing metal as alloying component (Me = Co, W) in a Ni-P amorphous matrix, were potentiostatically electrodeposited onto a polycrystalline Cu substrate. Deposition potential was established based on polarization curves of electrodeposition of Ni-Co-P, Ni-W-P and Ni-P alloy coatings. SEM, EDS, XRD and X-ray microanalysis methods, were applied for chemical and physical characterization of the obtained coatings. Linear analysis of Ni, Co and W distribution in the microregions of the appropriate alloy coating revealed that surface distribution of these elements is homogeneous what is due to a molecular mixing of the amorphous nickel matrix with the alloying components. It was found that the Ni-Co-P and Ni-W-P coatings have the amorphous structure like the Ni-P deposit and alloying components as Co or W are built-in into the appropriate coating in the amorphous form. The mechanism of the induced codeposition of these ternary Ni-Me-P coatings, has been discussed.

Abstract:

Methylsilsesquioxane (Me-SSQ) was incorporated into cyanate ester resin (CE) to obtain organic-inorganic hybrids with better dielectric properties in this study. First, methyltriethoxysilane was hydrolyzed and condensed to synthesize Me-SSQ. Then several Me-SSQ/CE hybrids containing different contents of Me-SSQ were prepared. The effect of Me-SSQ content on the dielectric and hot/wet properties of materials was investigated. Results showed that the Me-SSQ/CE hybrid containing 20wt% of Me-SSQ shows a dielectric constant of 2.78, which is much lower than the pure CE resin. At the same time, the dielectric loss of the Me-SSQ/CE hybrids was slightly increased (tanδ<0.006). It indicates that Me-SSQ/CE hybrid is a promising matrix materials for high-performance printed circuit board (PCB).

Abstract:

Приведено описание структурно-фазового состава образцов на основе Ti-49ат.%Al-2ат.%Me (Ме = Sc, Y, Dy, Ho, Ta). Образцы получены «Гидридной технологией», в условиях гидрирования металлов (Ti, Sc, Y, Dy, Ta, Ho) и последующего дегидрирования сформированных заготовок в вакуумной среде при нагреве. Методом просвечивающей электронной микроскопией обнаружено, что в образцах Ti-50Al, Ti-49Al-2Sc, Ti-49Al-2Y, Ti-49Al-2Ta (ат.%) в локальных местах в объеме образцов сформировалась ламельная структура. Микролегирование системы Ti-Al элементами иттриевой группы (Y, Ho, Dy) до 2 ат.% приводит к формированию изотипическихсоединений Y6Ti4Al43, Dy6Ti4Al43, Ho6Ti4Al43(гексагональная, P63/mcm). Для образца Ti-49ат.%Al-2ат.%Ta значение микротвердости составляет 2,15 ГПа. The structural and phase composition of the samples based on Ti-49at.%Al-2at.%Me (Ме = Sc, Y, Dy, Ho, Ta) has been presented. The samples were obtained by the “Hydride technology” during hydrogenation of (Ti, Sc, Y, Dy, Ta, Ho) metals and subsequent dehydration of the formed blanks in the vacuum environment when heated. Transmission electron microscopy allowed revealing the fact that a lamellar structure was formed in the Ti-50Al, Ti-49Al-2Sc, Ti-49Al-2Y, Ti-49Al-2Ta samples (at.%) in the local places in the sample volume. Microalloying the Ti-Al system with the elements of the yttrium group (Y, Ho, Dy) up to 2 at.% leads to the formation of isotypic Y6Ti4Al43, Dy6Ti4Al43, Ho6Ti4Al43compounds (hexagonal, P63/mcm). The microhardness value is 2.15 GPa for the Ti-49at.%Al-2at.%Ta sample.

Abstract:

The fields of polymer science, conductive composites, materials engineering, robotics, and human perception intersect at the development and application of synthetic human skin. To be accepted by human users, artificial human skin must meet several requirement benchmarks. Synthetic human skin must look realistic, but not be eerie or creepy, upsetting those using or interacting with the material. Synthetic skin must feel like human skin, including mechanical response, thermal conductivity, and tactile properties. Realistic synthetic human skin must be electrically conductive, so that the user may experience accurate sensations of touch and feel. Finally, synthetic human skin should possess some degree of self-healing behavior. This review provides a brief description of advances in these disparate aspects of synthetic skin science, from the perspective of a practicing conductive polymer composite scientist and engineer.

Abstract:

Advances in cell and tissue therapies are slow to be implemented in the clinic due to the limited standardization of safety and quality control techniques. Current approaches for monitoring cell and tissue manufacturing processes are time and labor intensive, costly, and lack commercial scalability. One method to improving in vitro manufacturing processes includes utilizing the coupled magnetic and mechanical properties of magnetoelastic (ME) materials as passive and wireless sensors and actuators. Specifically, ME materials can be used in quantifying cell adhesion, detecting contamination, measuring biomarkers, providing biomechanical stimulus, and enabling cell detachment in bioreactors. This review outlines critical design considerations for ME systems and summarizes recent developments in utilizing ME materials for sensing and actuation in cell and tissue engineering.

Abstract:

Nanoparticles with small diameters and large surface areas have potential advantages and are actively utilized in various fields related to biomedical and catalytic applications. Multifunctional applications can be achieved by endowing nanoparticles with piezoelectric, quantum dot, magnetothermal, and piezoluminescent properties. In particular, multiferroic magnetoelectric nanoparticles (MENPs) can generate electricity by coupling piezoelectric and magnetostrictive properties when an external magnetic field, which is harmless to the human body, is applied. In this regard, magnetoelectricity (ME) induced by a magnetic field makes MENPs useful for various biomedical and electrocatalytic applications. The ME voltage coefficients, which express the efficiency of energy conversion from magnetic field to electricity, show differences depending on the setup for ME measurements of MENPs. Therefore, numerous attempts have been made to optimize the ME characterization method to reduce measurement errors resulting from charge leakages caused by the specimen preparation, as well as to investigate the ME effect of a single nanoparticle. Our review is focused on the structures, syntheses (hydrothermal and sol–gel methods), activation mechanism, and measurement of magnetoelectricity, as well as applications, of core–shell MENPs.

Abstract:

Versatile applications and broad interest in amorphous electrode materials, especially the nickel-phosphorus coatings, primarily results from their unique properties and low-production costs in comparison to precious metals. This paper discusses the most important research conducted over several years into the Me-P layers, in particular the Ni-P and Ni-Me-P ones, which led to only partial understanding of these amorphous alloys. Methods of increasing the catalytic activity of the Ni-P layers in the process of electroevolution of hydrogen are also discussed because the electrolytic layers of amorphous nickel still seem to be the promising electrode material.

Abstract:

Redox-active organic molecules (ROMs) are promising electrode materials for next-generation rechargeable batteries owing to their beneficial advantages of environmental friendliness, natural abundance, low cost, and possible high theoretical capacity. However, they suffer from a serious dissolution problem in organic electrolytes and low electrical conductivity, limiting their practical application. In particular, despite many advantages such as easy synthesis, potential low cost, and convenient processing, small-molecule electrode materials have typically showed far inferior stability and rate performance than polymeric materials. Herein, two isoindigo-based small molecules, isoindigo (Me-IIG) and thienoisoindigo (Me-TIIG), were synthesized and evaluated as a cathode material in lithium-organic batteries. In a Li coin cell, Me-IIG and Me-TIIG electrode exhibited specific capacity of 156 and 168 mAh g-1 at 1C, corresponding to 84% and 95% of capacity utilization, respectively. The Me-TIIG with better planar molecular geometry than the Me-IIG showed much lower solubility in organic electrolytes with the aid of strong intra- and intermolecular interactions. As a result, the Me-TIIG electrode presented remarkably improved cycling stability, retaining 96% of the initial capacity after 500 cycles at 5C rate. Moreover, Me-TIIG exhibited lower reorganization energy than Me-IIG, which can facilitate a kinetically faster electrochemical pathway, leading to superior rate capability. It should be noted that the Me-TIIG electrode showed excellent rate performance achieving 70% capacity retention at a high rate of 20C.

Abstract:

Since the revival of multiferroic laminates with giant magnetoelectric (ME) coefficients, a variety of multifunctional ME devices, such as sensor, inductor, filter, antenna etc. have been developed. Magnetoelastic materials, which couple the magnetization and strain together, have recently attracted ever-increasing attention due to their key roles in ME applications. This review starts with a brief introduction to the early research efforts in the field of multiferroic materials and moves to the recent work on magnetoelectric coupling and their applications based on both bulk and thin-film materials. This is followed by sections summarizing historical works and solving the challenges specific to the fabrication and characterization of magnetoelastic materials with large magnetostriction constants. After presenting the magnetostrictive thin films and their static and dynamic properties, we review micro-electromechanical systems (MEMS) and bulk devices utilizing ME effect. Finally, some open questions and future application directions where the community could head for magnetoelastic materials will be discussed.

Abstract:

Abstract Background Partnerships among patients, families, caregivers, and clinicians are critical to helping patients lead their best lives given their specific genetics, conditions, circumstances, and the environments in which they live, work, and play. These partnerships extend to the development of health information technology, including clinical decision support (CDS). Design of these technologies, however, often occurs without a profound understanding of the true needs, wants, and concerns of patients and family members. Patient perspective is important not only for patient-facing applications but for provider-facing applications, especially those intended to support shared decision-making. Objectives Our objective is to describe models for effectively engaging patients and caregivers during CDS development and implementation and to inspire CDS developers to partner with patients and caregivers to improve the potential impact of CDS. Methods This article serves as a case study of how two patient activists successfully implemented models for engaging patients and caregivers in a federal program designed to increase the uptake of research evidence into clinical practice through CDS. Models included virtual focus groups, social media, agile software development, and attention to privacy and cybersecurity. Results Impact on the federal program has been substantial and has resulted in improved CDS training materials, new prototype CDS applications, prioritization of new functionality and features, and increased engagement of patient and caregiver communities in ongoing projects. Among these opportunities is a group of developers and patient activists dedicated and committed to exploring strategic and operational opportunities to codesign CDS applications. Conclusion Codesign and implementation of CDS can occur as a partnership among developers, implementers, patients, cybersecurity and privacy activists, and caregivers. Several approaches are viable, and an iterative process is most promising. Additional work is needed to investigate scalability of the approaches explored by this case study and to identify measures of meaningful inclusion of patients/caregivers in CDS projects.

Abstract:

Macro-encapsulated phase change material (PCM) lightweight aggregates (ME-LWA) were produced and evaluated for their mechanical and thermal properties in road engineering applications. The ME-LWAs were first characterised in terms of their physical and geometrical properties. Then, the ME-LWAs were investigated in detail by applying the European Standards of testing for the Bulk Crushing Test and the Polished Stone Value (PSV) coefficient as well as Micro-Deval and laboratory profilometry. In addition, the thermal performance for possible construction of smart pavements with the inclusion of ME-LWAs for anti-ice purposes was determined. The crushing resistance of the ME-LWAs was improved, while their resistance to polishing was reduced. Thermal analysis of the encapsulated PCM determined it to possess excellent thermal stability and a heat storage capacity of 30.43 J/g. Based on the research findings, the inclusion of ME-LWAs in surface pavement layers could be considered a viable solution for the control of surface temperatures in cold climates. Road safety and maintenance could benefit in terms of reduced ice periods and reduced treatments with salts and other anti-ice solutions.

Abstract:

Magnetoelectric multiferroics are solid-state materials which exhibit a coupling between ferroelectric and magnetic orders. This phenomenon is known as the magnetoelectric (ME) effect. Multiferroic materials possess a wide range of potential applications in such fields as metrology, electronics, energy harvesting & conversion, and medicine. Multiferroic research is facing two main challenges. Firstly, scientists are continuously trying to obtain a material with sufficiently strong, room-temperature ME coupling that would enable its commercial application. Secondly, the measurement techniques used in multiferroic research are often problematic to implement in a laboratory setting and fail to yield reproducible results. The aim of the present work is to discuss three most commonly used methods in multiferroic studies; the lock-in technique, the Sawyer-Tower (S-T) circuit and dielectric constant measurements. The paper opens with a general description of multiferroics which is followed by mathematical representation of the ME effect. The main body deals with the description of the aforementioned measurement techniques. The article closes with a conclusion and outlook for future research.

Abstract:

A kind of nonfunctional oligomeric silsesquioxane (SSQ), methylsilsesquioxane (Me-SSQ), was used to modify cyanate ester resin (CE) in this paper. First, Me-SSQ was synthesized by the hydrolysis and condensation of methyltriethoxysilane. Then a series of Me-SSQ/CE hybrids containing 0wt%, 1wt%, 5wt%, 10wt% and 20wt% of Me-SSQ were prepared. Curing reactivity of the hybrid materials was studied by differential scanning calorimetry (DSC). Mechanical properties of the Me-SSQ/CE hybrids were studied systematically. Impact strength of the Me-SSQ/CE hybrids reaches its maximum value when Me-SSQ content is 5wt%. However, the flexural strength reaches the maximum value when Me-SSQ content is 1wt%. SEM images accord well with the mechanical properties. It is concluded that appropriate amount of Me-SSQ is favorable to improve the mechanical properties of Me-SSQ/CE hybrid materials.

Abstract:

A theoretical model is presented for the frequency response of magnetoelectric (ME) effect in the magnetostrictive-piezoelectric (MS-PE) disk–ring composite structures with the PE ring polarized radially. Based on the governing equations of materials and elastodynamic equations of continuum media, the expressions of the ME voltage coefficients for the axial and vertical mode are derived in terms of materials parameters and geometry dimensions. Estimated ME voltage coefficient versus frequency profiles predict a giant ME effect at the electromechanical resonance (EMR) with strong interfacial mechanical coupling. It is shown that increased effective length due to radial polarization instead of thickness polarization of PE-ring is responsible for the improved ME effect in the radially polarized disk–ring structure. The dependences of low-frequency ME effect, resonance frequency and resonance ME effect on geometry dimensions are predicted by our model. Some of the theoretical results are compared with the experimental results, showing good coincidence. It is suggested that proper resonance frequency and better ME effect in the disk–ring structure can be obtained by selecting appropriate materials, optimizing polarization direction and varying its geometry dimensions, which is of interest for the potential application of ME composites in novel multifunctional devices, such as sensors, transducers and memories.

Abstract:

The prediction of magnetoelectric (ME) coupling in nano-scaled multiferroic composites is significant for nano-devices. In this paper, we propose a nonlinear multi-field coupling model for ME effect in layered multiferroic nanocomposites based on the surface stress model, strain gradient theory and nonlinear magneto-elastic-thermal coupling constitutive relation. With this novel model, the influence of external fields on strain gradient and flexoelectricity is discussed for the first time. Meanwhile, a comprehensive investigation on the influence of size-dependent parameters and multi-field conditions on ME performance is made. The numerical results show that ME coupling is remarkably size-dependent as the thickness of the composites reduces to nanoscale. Especially, the ME coefficient is enhanced by either surface effect or flexoelectricity. The strain gradient in composites at the nano-scale is significant and influenced by the external stimuli at different levels via the change in materials’ properties. More importantly, due to the nonlinear multi-field coupling behavior of ferromagnetic materials, appropriate compressive stress and temperature may improve the value of ME coefficient and reduce the required magnetic field. This paper provides a theoretical basis to analyze and evaluate multi-field coupling characteristics of nanostructure-based ME devices.

Abstract:

Elementary social studies can and should be taught through an age-appropriate lens of complexity which includes multiple perspectives that students evaluate in order to form evidence-based claims. Social Studies textbooks have often been critiqued for oversimplifying historical events with sanitized versions of the past (Calderón, 2014; Ladson-Billings, 2003; Loewen, 2008; Peterson, 2008). The tendency in elementary social studies has been to smooth over conflict (Cowhey, 2006; Peterson, 2008). To help elementary teachers disrupt sanitized versions of social studies, I urge that we start trusting students to grapple with complex narratives. First, I demonstrate the prolific existence of sanitized stories in social studies textbooks. Next, a rationale for and descriptions of complex narratives are provided. Lastly, a ‘Complex Questioning Framework’ is presented to help educators identify sanitized social studies in order to add the necessary complexities.

Abstract:

Multiferroic materials exhibited more than one ferroic properties of piezoelectric, magnetostrictive, and magnetoelectric. Among the multiferroic materials, magnetoelectric (ME) materials coexisting ferroelectric and ferromagnetic properties has attracted great attention due to its unique applications such as energy harvesters, highly-sensitive magnetic sensors, actuators, memory devices. With the increase in demand of flexible and multifunctional electronic devices, polymer-based ME composites consisting of ferroelectric polymer matrix and ferromagnetic ceramic nanofillers have been developed by optimization of materials, structure, and process. In this review, we described research history and feasible applications for the polymer-based ME composites. We believe that the polymer-based ME composites can be a potential candidate for self-powered energy and sensing devices relevant to the fourth industrial revolution in the near future.

Abstract:

Magnetoelectric (ME) materials have attracted continuous attention due to their potential applications in the fields of sensors, actuators, and transducers. A large ME coupling originated from a clamping structure was reported. ME coefficient of 0.95V cm1Oe1was obtained without amplifier at the planar acoustic frequency 60 KHz. The results show that large ME coupling can be obtained in the clamping structure through normal stress, and longitudinal ME effect could be better than transverse ME effect.

Abstract:

The aim of this study was to evaluate the effects of two endocrown designs and computer aided design/manufacturing (CAD/CAM) materials on stress distribution and failure probability of restorations applied to severely damaged endodontically treated maxillary first premolar tooth (MFP). Two types of designs without and with 3 mm intraradicular extensions, endocrown (E) and modified endocrown (ME), were modeled on a 3D Finite element (FE) model of the MFP. Vitablocks Mark II (VMII), Vita Enamic (VE), and Lava Ultimate (LU) CAD/CAM materials were used for each type of design. von Mises and maximum principle values were evaluated and the Weibull function was incorporated with FE analysis to calculate the long term failure probability. Regarding the stresses that occurred in enamel, for each group of material, ME restoration design transmitted less stress than endocrown. During normal occlusal function, the overall failure probability was minimum for ME with VMII. ME restoration design with VE was the best restorative option for premolar teeth with extensive loss of coronal structure under high occlusal loads. Therefore, ME design could be a favorable treatment option for MFPs with missing palatal cusp. Among the CAD/CAM materials tested, VMII and VE were found to be more tooth-friendly than LU.

Abstract:

The influence of mechanical activation on the characteristics and mechanism of ignition of self-propagating high-temperature synthesis processes of different silicides in the systems Me–Si (Me =Ti, Nb, Mo) was investigated. The results show that mechanical activation does not alter the mechanism involved but influences significantly the ignition characteristics. The influence, however, strongly depends on the stoichiometry of the mixtures. The composition Ti:Si = 1:2 shows the largest influence, with the ignition temperatures decreasing from 1400 °C for unmilled powders to about 600 °C for powders milled for several hours. The compositionsTi:Si = 5:3, Nb:Si = 1:2 show less pronounced decreases, while the compositionMo:Si = 1:2 shows no decrease. These differences are discussed in terms of the role of microstructure in the reaction mechanism and the different response of the systems to contamination, particularly from oxygen. The results suggest that for these systems self-ignition processes during milling cannot be explained only on the basis of the decrease in the ignition temperature.
