Abstract:

The photo-stimulating discharge (PSD) and ultraviolet-visible spectrometry were used to characterize the polyethylene (PE) and nano-hybrid PE trap before and after ultraviolet aging. In PE with the increasing of ultraviolet aging time, shallow traps reduce gradually and deep traps increase gradually, but for the nano-hybrid PE, shallow traps increase gradually and deep traps reduce gradually. Experiments show that: in the process of aging PE produces oxidation products such as carbonyl, hydroxyl etc. The incorporation of impurities can inhibit the injection of space charges, so as to achieve the purpose of improving electric field distortion in the body of the PE.

Abstract:

We have developed an efficient computational scheme for integration of the classical Hamilton equations describing the ion dynamics confined in the radio-frequency field of the Paul trap. It has permitted a quantitative treatment of cold atom-ion resonant collisions in hybrid atom-ion traps with taking into account unremovable ion micromotion caused by the radio-frequency fields (V.S. Melezhik et. al., Phys. Rev. A100, 063406 (2019)). The important element of the hybrid atom-ion systems is the electromagnetic Paul trap confining the charged ion. The oscillating motion of the confined ion is defined by two frequencies of the Paul trap. It is the frequency of the order of 100 kHz due to the constant electric field and the radio-frequency of about 1-2 MHz defined by the alternating electromagnetic field of the ion trap. The necessity to accurately treat the ion motion in the combined field with two time scales defined by these two very different frequencies has demanded to develop the stable computational scheme for integration of the classical Hamilton equations for the ion motion. Moreover, the scheme must be stable on rather long time-interval of the ion collision with the cold atom ∼ 10 × 2/ defined by the atomic trap frequency ∼ 10 kHz and in the moment of the atom-ion collision when the Hamilton equations are strongly coupled. The developed numerical method takes into account all these features of the problem and makes it possible to integrate the system of coupled quantum-semiclassical equations with the necessary accuracy and quantitatively describes the processes of atomic-ion collisions in hybrid traps, including resonance effects.

Abstract:

In the development of atomic, molecular, and optical (AMO) physics, atom-ion hybrid systems are characterized by the presence of a new tool in the experimental AMO toolbox: atom-ion interactions. One of the main limitations in state-of-the-art atom-ion experiments is represented by the micromotion component of the ions’ dynamics in a Paul trap, as the presence of micromotion in atom-ion collisions results in a heating mechanism that prevents atom-ion mixtures from undergoing a coherent evolution. Here, we report the design and the simulation of a novel ion trapping setup especially conceived of for integration with an ultracold atoms experiment. The ion confinement is realized by using an electro-optical trap based on the combination of an optical and an electrostatic field, so that no micromotion component will be present in the ions’ dynamics. The confining optical field is generated by a deep optical lattice created at the crossing of a bow-tie cavity, while a static electric quadrupole ensures the ions’ confinement in the plane orthogonal to the optical lattice. The setup is also equipped with a Paul trap for cooling the ions produced by photoionization of a hot atomic beam, and the design of the two ion traps facilitates the swapping of the ions from the Paul trap to the electro-optical trap.

Abstract:

Starting from a degenerate Bose gas in a hybrid trap combining a magnetic quadrupole trap and an attractive optical trap resulting from a focused laser beam, we demonstrate the efficient loading of this quantum gas into a shell-shaped trap. The shell trap is purely magnetic and relies on adiabatic potentials for atoms in an inhomogeneous magnetic field dressed by a radiofrequency (rf) field. We show that direct rf evaporation in the hybrid trap enables an efficient and simple preparation of the cold sample, well adapted to the subsequent loading procedure. The transfer into the shell trap is adiabatic and limits the final excitation of the center-of-mass motion to below 2 [Formula: see text]m.

Abstract:

ABSTRACT Pseudomonas putida G7 carries a naphthalene-catabolic and self-transmissible plasmid, NAH7, which belongs to the IncP-9 incompatibility group. Adjacent to the putative origin of conjugative transfer (oriT) of NAH7 are three genes, traD, traE, and traF, whose functions and roles in conjugation were previously unclear. These three genes were transcribed monocistronically and thus were designated the traD operon. Mutation of the three genes in the traD operon resulted in 10- to 105-fold decreases in the transfer frequencies of the plasmids from Pseudomonas to Pseudomonas and Escherichia coli and from E. coli to E. coli. On the other hand, the traD operon was essential for the transfer of NAH7 from E. coli to Pseudomonas strains. These results indicated that the traD operon is a host-range modifier in the conjugative transfer of NAH7. The TraD, TraE, and TraF proteins were localized in the cytoplasm, periplasm, and membrane, respectively, in strain G7 cells. Our use of a bacterial two-hybrid assay system showed that TraE interacted in vivo with other essential components for conjugative transfer, including TraB (coupling protein), TraC (relaxase), and MpfH (a channel subunit in the mating pair formation system).

Abstract:

Abstract Fumed silica-filled polypropylene (PP)-based nanodielectrics were studied in this work. To not only improve the dispersion of the silica but also introduce deep charge traps into the polymeric matrix, five types of modified silicas were manufactured with different surface modifications. The modified silica surfaces comprise an inner and a surface layer. The inner layer contains a polar urethane group for tailoring the charge trap properties of the PP/propylene–ethylene copolymer nanocomposites, whereas the surface layer consists of hydrocarbons (ethyl-, tert-butyl-, cyclopentyl-, phenyl-, or naphthalenyl moieties) in order to gain a good dispersion of the silica in the unpolar polymer blend. Scanning electron microscopic pictures proved that these tailored silicas show a much better dispersion than the unmodified one. Thermally stimulated depolarization current measurements revealed the ability of the silica to introduce deep charge traps with low trap density. The trap depth distribution depends on the type of the unpolar surface layer consisting of the different hydrocarbons. Among these five differently modified silicas, the introduction of the one with a surface layer consisting of tert-butyl moieties resulted in the lowest charge injection and the lowest charge current in the nanocomposite, proving good dielectric performance. Additionally, this silica exhibits good dispersion in the polymeric matrix, indicating a promising performance for nanodielectric application.

Abstract:

AbstractGhost fishing is the capacity of lost traps to continue to catch and kill animals. In the spiny lobster (Panulirus argus) fishery in Florida, the effects of ghost fishing are of particular concern, given the estimated 10s of 1000s of traps lost annually. We distributed 40 each of the three types of lobster traps (wire, wood–wire hybrid, and wood slat) at three locations in the Florida Keys to simulate ghost fishing. Divers monitored these traps biweekly for 1 year then monthly for two additional years, recording the time ghost traps remained intact and continued to fish, as well as the number of live and dead lobsters and other animals in each trap. Wood slat and hybrid traps remained intact and fished for 509 ± 97 (median ± median absolute deviation) and 480 ± 142 d, respectively. Wire traps fished significantly longer (779.5 ± 273.5 d, p < 0.001), and several fished until the end of the experiment (1071 d). Traps in Florida Bay fished longer (711.5 ± 51.5 d) than traps inshore (509 ± 94.5 d) and offshore (381 ± 171 days; p < 0.001) in the Atlantic Ocean. More lobsters were observed in hybrid traps (mean = 4.81 ± 0.03 s.e.) than in wood slat (3.85 ± 0.16) or wire traps (3.17 ± 0.03; F = 40.15, d.f. = 2, p < 0.001). Wire traps accounted for 83% of fish confined overall and 74% of the dead fish observed in traps. Ghost traps in Florida Bay and Atlantic inshore killed 6.8 ± 1.0 and 6.3 ± 0.88 lobsters per trap annually, while Atlantic offshore traps killed fewer (3.0 ± 0.69) lobsters, likely as a result of lower lobster abundance in traps. The combined effects of greater lobster mortality and greater abundance of lost traps in inshore areas account for the majority of the estimated 637 622 ± 74 367 (mean ± s.d.) lobsters that die in ghost traps annually.

Abstract:

AbstractA hybrid asymptotic-numerical method is developed to approximate the mean first passage time (MFPT) and the splitting probability for a Brownian particle in a bounded two-dimensional (2D) domain that contains absorbing disks, referred to as “traps”, of asymptotically small radii. In contrast to previous studies that required traps to be spatially well separated, we show how to readily incorporate the effect of a cluster of closely spaced traps by adapting a recently formulated least-squares approach in order to numerically solve certain local problems for the Laplacian near the cluster. We also provide new asymptotic formulae for the MFPT in 2D spatially periodic domains where a trap cluster is centred at the lattice points of an oblique Bravais lattice. Over all such lattices with fixed area for the primitive cell, and for each specific trap set, the average MFPT is smallest for a hexagonal lattice of traps.

Abstract:

The synthesis of PbSe nanoparticles were carried out by colloidal route using lead acetate as starting material with Oleic acid/TOP as capping agents at the optimized growth temperature. The phase and surface analysis of oleic acid/TOP capped PbSe nanocrystallites were studied in detail in this article. Current-voltage characteristics of pristine and lead selenide quantum dots (PbSe QDs) incorporated in poly(2-methoxy,5-(2′-ethylhexyloxy)-p-phenylenevinylene (MEH-PPV) thin films have been studied at different temperatures (306–125 K) in hole only device configuration, i.e., ITO/poly(ethylene-dioxythiophene):polystyrenesulphonate (PEDOT:PSS)/MEH-PPV/Au and ITO/PEDOT:PSS/MEH-PPV:PbSe/Au. It has been found that the presence of PbSe QDs in MEH-PPV results in the modulation of the charge transport mechanism from dual conduction mechanism, i.e., trap and mobility model to only trap model. It signifies that the traps are becoming shallower due to reduction in trap density from 2×1017 to 1.2×1017 cm−3 as well as trap energy reduces from 74 meV to 62 meV on the incorporation of PbSe QDs.

Abstract:

One of the limiting factors to high device performance in photovoltaics is the presence of surface traps. Hence, the understanding and control of carrier recombination at the surface of organic-inorganic hybrid perovskite is critical for the design and optimization of devices with this material as the active layer. We demonstrate that the surface recombination rate (or surface trap state density) in methylammonium lead tribromide (MAPbBr3) single crystals can be fully and reversibly controlled by the physisorption of oxygen and water molecules, leading to a modulation of the photoluminescence intensity by over two orders of magnitude. We report an unusually low surface recombination velocity of 4 cm/s (corresponding to a surface trap state density of 108cm−2) in this material, which is the lowest value ever reported for hybrid perovskites. In addition, a consistent modulation of the transport properties in single crystal devices is evidenced. Our findings highlight the importance of environmental conditions on the investigation and fabrication of high-quality, perovskite-based devices and offer a new potential application of these materials to detect oxygen and water vapor.

Full text

Abstract:

A human gene encoding a protein that specifically binds to the intracellular domain of the 75 kDa type-2 tumour necrosis factor (TNF) receptor (TNFR-2IC) has been identified using the yeast-based two-hybrid system. The N-terminal half of the TNF receptor-associated protein (TRAP) contains RING finger and zinc finger motifs often found in DNA-binding proteins including transcription factors. The 2.4 kb TRAP mRNA was barely detectable, if present at all, in lung, and variably expressed in heart, liver, placenta, brain, skeletal muscle, kidney and the pancreas; interestingly, the TRAP was more highly expressed in transformed cell lines than in normal tissues. This observation may be consistent with a role for this TRAP in promoting or regulating cellular proliferation. After in vitro transcription/translation and 35S labelling the TRAP was precipitated using a fusion protein consisting of glutathione S-transferase and the intracellular domain of TNFR-2 (TNFR-2IC), which showed that the two proteins directly interact in a mammalian cell-free system and also that identification of the TRAP was not an artifact of the two-hybrid system. By using truncated TNFR-2ICs for in vitro precipitation of 35S-TRAP, it was shown that the C-terminal half of the TNFR-2IC contains the domain necessary for interaction with TRAP. The TRAP identified in the present study shares considerable homology with, and may be the human homologue of, a mouse protein, TNF receptor-associated factor 2 (TRAF2), that binds mouse TNFR-2.

Full text

Abstract:

Zeeman slowers come in two commonly used types: electromagnet-based slowers and permanent-magnet slowers. Both have characteristic advantages and disadvantages. The electric currents required to create strong magnetic fields lead to heat dissipation that limits the achievable fields, while permanent-magnet slowers cause bias magnetic fields at the position of the magneto-optical trap. Here, we combine both approaches and their advantages at our lithium-6 triangular-lattice quantum gas microscope and extend the field of an electromagnet-based Zeeman slower using permanent magnets. We observe nearly doubled loading rates of the magneto-optical trap and no significant stray fields in the trapping region. Our approach allows for a stronger magnetic field in places where geometric constraints prevent the use of coils, and it provides a low-cost upgrade to the loading rate at established experiments.

Abstract:

Regulations imposed on the use of chemical insecticides call for the development of environmental-friendly pest management strategies. One of the most effective strategies is the push–pull system, which takes advantage of the behavioral response of the insect to the integration of repellent stimuli; it expels the pest out of the main crop (push), while attracting stimuli (attractants) pull the pest to an alternative crop or trap (pull). The objective of this study was to design a push–pull system to control Spodoptera frugiperda in maize crops (Zea mays) in Morelos, Mexico. Data on reproductive potential, larvae development, food consumption and olfactometry were used to obtain a Trap Plant Selection Index (TRAPS) based on Principal Component Analysis. This TRAPS was used to select the most suitable plants. The degree of repellency of potential plants to be used as the trap crop was studied with four-way olfactometers. S. frugiperda females oviposited more eggs on Brachiaria hybrid cv. Mulato II, Panicum maximum cv. Mombasa and Panicum maximum cv. Tanzania than on Z. mays, regardless of the fact that these plants delayed the development of their offspring. Dysphania ambrosioides, Tagetes erecta and Crotalaria juncea were less attractive to S. frugiperda females. Therefore, the former plants could be used as crop traps, and the latter as intercropped repellent plants in a push–pull system.

Hybrid 3D/2D perovskites combine the high efficiency of 3D perovskites and the stability of 2D perovskites, and possess longer photoluminescence lifetimes, lower trap-state densities and enhanced moisture tolerance. The hybrid 3D/2D structure is a successful strategy to improve stability without sacrificing conversion efficiency.

Abstract:

Informed Rapidly-exploring Random Tree* (Informed-RRT*) merupakan hasil pengembangan dari algoritma Rapidly-exploring Random Tree (RRT) yang dapat menghasilkan solusi jalur yang bersifat asimptotik optimal tetapi waktu komputasi yang dibutuhkan menjadi lebih lama. Pada awalnya algoritma Informed-RRT* masih menggunakan metode random sampling yang mana metode ini akan mengambil sampel acak pada ruang pencarian. Pengambilan sampel acak inilah yang akan membuat waktu komputasi menjadi tidak optimal. Penelitian ini bertujuan untuk merancang algoritma Informed-RRT* menggunakan metode hybrid sampling. Metode hybrid sampling merupakan integrasi dari beberapa metode pengambilan sampel. Pada pengujian ini, performansi metode random sampling akan dibandingkan dengan perfomansi metode hybrid sampling dalam hal waktu komputasi. Pengujian metode hybrid sampling pada algoritma Informed-RRT* ini berbasis simulasi dan dilakukan pada lingkungan narrow, clutter, trap. Hasil yang didapatkan dari pengujian ini adalah penggunaan metode hybrid sampling pada algoritma Informed-RRT* mampu menghasilkan performansi waktu rata- rata komputasi yang lebih cepat 26,4 detik bila dibandingkan dengan metode random sampling pada lingkungan clutter. Pada lingkungan narrow metode hybrid sampling menghasilkan waktu komputasi 24,52 detik lebih cepat bila dibandingkan dengan metode random sampling. Pada lingkungan trap metode hybrid sampling menghasilkan waktu komputasi 5,25 detik lebih cepat dibandingkan dengan metode random sampling. Dari data hasil pengujian, metode hybrid sampling ini dapat menjadi metode pangambilan sampel alternatif untuk digunakan pada algoritma Informed-RRT*

Abstract:

Представлена гибридная математическая модель осесимметричной плазменной ловушки, основанная на кинетическом описании для ионной компоненты плазмы и приближении МГД для электронной компоненты.

На основе разработанного алгоритма создан комплекс программ для исследования механизмов формирования самосогласованной структуры магнитного поля ловушки. A hybrid mathematical model of an axisymmetric plasma trap based on the kinetic description for the ion component of the plasma and the MHD approximation for the electronic component is presented. On the basis of the hybrid model, a two-dimensional algorithm is developed to study the dynamics of injected particles in the trap field. The motion of the ion component is calculated by the particle-in-cell method. Finite-difference schemes are used to calculate the magnetic field and the electron component of the plasma. On the basis of the developed algorithm, a program code is created to study the mechanisms of the self-consistent magnetic field structure formation.

Abstract:

Survival, growth, and diet were compared for farmed, hybrid, and wild Atlantic salmon (Salmo salar) families from the eyed egg to the smolt stage in River Guddalselva, Hardangerfjord, Norway. All individuals that survived until the smolt stage were captured in a Wolf trap and identified to one of the 69 experimental families using microsatellite markers. Survival of farmed salmon progeny was significantly lower than that of hybrids and wild progeny. However, survival varied considerably, from 0.17% to 6.4%, among farmed families. Egg size had an important influence on survival. Half-sib hybrid families with a farmed mother had higher survival when fathered by wild salmon than by farmed salmon. The overall relative survival of farmed families compared with that of their hybrid half-sib families fell from 0.86 in the second cohort to 0.62 in the last cohort with increasing fish density. Smolts of farmed parents showed significantly higher growth rates than wild and hybrid smolts. The overlap in diet among types of crosses demonstrates competition, and farm and hybrid progeny therefore will reduce the river’s capacity for production of wild salmon.

Abstract:

Abstract. Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river reaches. In turn, the unwanted permanent trapping of sediment during small, non-hazardous floods can result in the ecological and morphological degradation of downstream reaches. This study experimentally analyses a novel concept for permeable sediment traps. For ensuring the sediment transfer up to small floods, a guiding channel implemented in the deposition area of a sediment trap was systematically studied. The bankfull discharge of the guiding channel corresponds to a dominant morphological discharge. At the downstream end of the guiding channel, a permeable barrier (check dam) triggers sediment retention and deposition. The permeable barrier consists of a bar screen for mechanical deposition control, superposed to a flow constriction for the hydraulic control. The barrier obstructs hazardous sediment transport for discharges that are higher than the bankfull discharge of the guiding channel without the risk of unwanted sediment flushing (massive self-cleaning).

Abstract:

Resistive random access memory (RRAM) is emerging as a new class of nonvolatile memory that offers promising electronic properties and simple metal-insulator-metal (MIM) structures for sandwich layers, such as organics, inorganics, and hybrid materials. Hybrid structures have attracted much interest recently because of their advantageous properties. The combination of chitosan (CS) and graphene oxide (GO) acts as switching layers in the Al/CS-GO/FTO RRAM structure it is studied with bipolar switching behavior at approximately 102 ON/OFF ratios during 100 cycles. This hybrid interaction is identified by shifts in the D, G, and 2D bands using Raman spectroscopy. The conduction mechanism is proposed to be a space-charge-limited conduction (SCLC) mechanism and trap-assisted tunneling conduction mechanism in the ON and OFF states, respectively. The trapped and detrapped electrons move through the trap sites with external electric fields, and this movement is responsible for the switching mechanism of the CS-GO nanocomposite memory device.

Abstract:

Since their introduction, the interaction trap and other two-hybrid systems have been used to study protein-protein interactions. Despite their general use, little is known about the extent to which the degree of protein interaction determined by two-hybrid approaches parallels the degree of interaction determined by biochemical techniques. In this study, we used a set of lexAop-LEU2 and lexAop-lacZ reporters to calibrate the interaction trap. For the calibration, we used two sets of proteins, the Myc-Max-Mxi1 helix-loop-helix proteins, and wild-type and dimerization-defective versions of the lambda cI repressor. Our results indicate that the strength of interaction as predicted by the two-hybrid approach generally correlates with that determined in vitro, permitting discrimination of high-, intermediate-, and low-affinity interactions, but there was no single reporter for which the amount of gene expression linearly reflected affinity measured in vitro. However, some reporters showed thresholds and only responded to stronger interactions. Finally, some interactions were subject to directionality, and their apparent strength depended on the reporter used. Taken together, our results provide a cautionary framework for interpreting affinities from two-hybrid experiments.

Abstract:

Plumage damage (PD) resulting from severe feather pecking (SFP) is a significant problem for animal welfare, performance, and economics in commercial laying hen farms. Genetics, nutrition, and housing conditions are central complexes that contribute to the multifactorial cause of SFP. Practical experience suggests that infestation by the poultry red mite (PRM), which is the most severe ectoparasite of laying hens in cage-free housing systems, may be a risk factor for the occurrence of PD, although evidence-based findings are lacking. The objective of this longitudinal observational field study was to investigate the effects of PRM infestation of commercial laying flocks on the occurrence of PD. Integument scoring (plumage damage and skin lesions) and the quantification of PRM infestation using mite traps were conducted during the laying period of 28 laying flocks, with an average flock size of 12,357 birds in barn (n = 21) or free-range (n = 7) systems. Across all flocks and survey times, the median PRM mass per trap was 0.7 mg (1.-3. quartile: 0.0–19.3 mg/trap), corresponding to a median count of 65.2 mites/trap (1.-3. quartile: 0.0–246.8 mites/trap). Binary logistic regression models revealed an association between PD and skin lesions with hen age, housing system, and hybrid type (p<0.001). The PRM load also affected the plumage condition, where PD increased with increasing PRM infestation (p<0.001). In addition, the PRM load tended to have an effect on skin injuries (p = 0.097). In conclusion, this longitudinal study identified the PRM load in laying hen flocks as a risk factor for PD.

Abstract:

In the pineapple growing region of Lebrija, Santander, one of the largest such regions in Colombia, five farms were selected, and a sampling of symphylids associated with this crop was carried out in the first months of cultivation in the variety Perolera and hybrid MD2. Two collecting methods were compared: i) the destructive method, with soil inspection around the roots, and ii) the bait-trap method with pieces of potato mixed with soil. These two methods were implemented in the same plots during five bimonthly samplings. Additionally, the percentage of root damage was estimated, defined as the percentage of roots that show bifurcation due to the damage caused by symphylids. All symphylids were identified as Hanseniella sp. Sampling of symphylids based on underground potato bait traps requires fewer samples to estimate population density and is a predictor of root damage while destructive sampling is not. Consequently, trap sampling could be a useful tool for monitoring and managing symphylids on pineapple. The abundance was related to soil moisture, and not to soil pH.

Abstract:

The plant Zantedeschia hybrida is colorful and suitable for cut flowers and potted plants. This study employed a colorimetric method for the determination of spathe color phenotypes in 27 Z. hybrida cultivars and classified them into six major color classes. To characterize the coloration mechanism of the Z. hybrida spathe, this study explored the main colorants and pigment distribution using high-performance liquid chromatography (HPLC) with photodiode array detection (DAD) and electrospray ionization mass spectrometry (ESI-MS), ultra-performance liquid chromatography/hybrid triple quadrupole linear ion trap mass spectrometry (UPLC-Q-TRAP-MS), and tissue sections. The results showed that flavonoids were colorants in the spathes of different color groups and that cyanidin (Cy) was the main colorant, whereas carotenoids were not detected in the spathe. Total anthocyanin (TA) content was negatively correlated with lightness (L*) of coloration, such that a spathe with a higher TA and thicker pigmented cell layer showed a deeper color; however, there was no correlation between deep coloration in a spathe and flattened upper epidermal cells. The difference in TA was the main reason for the color variation among Z. hybrida of different color groups, whereas the total flavones and flavonols (TF) played a key role in the coloration of the orange and yellow group.

Abstract:

Abstract Reaching ultracold temperatures within hybrid atom–ion systems is a major limiting factor for control and exploration of the atom–ion interaction in the quantum regime. In this work, we present results on numerical simulations of trapped ion buffer gas cooling using an ultracold atomic gas in a large number of experimentally realistic scenarios. We explore the suppression of micromotion-induced heating effects through optimization of trap parameters for various radio-frequency (rf) traps and rf driving schemes including linear and octupole traps, digital Paul traps, rotating traps and hybrid optical/rf traps. We find that very similar ion energies can be reached in all of them even when considering experimental imperfections that cause so-called excess micromotion. Moreover we look into a quantum description of the system and show that quantum mechanics cannot save the ion from micromotion-induced heating in an atom–ion collision. The results suggest that buffer gas cooling can be used to reach close to the ion’s groundstate of motion and is even competitive when compared to some sub-Doppler cooling techniques such as Sisyphus cooling. Thus, buffer gas cooling is a viable alternative for ions that are not amenable to laser cooling, a result that may be of interest for studies into cold controlled quantum chemistry and charged impurity physics.
