Segregation
Authors: Wolff Kristina B. 
Published: December 2018

AbstractSegregation is both the informal and formal separation of one group or population from another. Often this division is based on markers of difference, where race, ethnicity, gender, social class, educational attainment, sexual orientation, disability, age, or religion is used as the foundation for justifying a split between groups and populations. De facto segregation, the division of groups based on identity, culture, and social lives, is the most common. Legal separation, such as different accommodations for people based on race, gender, or nation status is de jure segregation. The repercussions of these separations are vast, creating and supporting structural inequality within societies.

Variables, Independent
Authors: Delucchi Michael 
Published: December 2018

Abstract
Quantitative methods are used in sociology to identify causal relationships that explain human social behavior. This requires sociologists to specify the independent variable (cause) and the dependent variable (effect). The independent variable produces the effect in a causal relationship and must occur in time before the dependent variable. An independent variable is the treatment (or stimulus) within a quantitative study design that is hypothesized to affect the dependent variable. Only the simplest sociological research includes just one independent variable, whereas most studies contain multiple independent variables hypothesized to predict a single dependent variable. These other variables, referred to as control variables, are a special type of independent variable included in sociological studies because they represent other potential causes of the dependent variable.

Published: December 2018

AbstractAn autonomous self‐healing system, inspired by transportation processes inherent to biology, is described for materials transportation and repair. The selected model system combines inorganic nanoparticles (NPs) on damaged substrates with functional emulsion droplets that pick up the particles from pristine portions of the substrate and deposit them into damaged regions. The droplets are stabilized by polymer surfactants containing phosphorylcholine groups, a polymer composition selected to impart surfactant properties for droplet stabilization as well as fouling resistance to prevent irreversible droplet adsorption on the substrates. Both the NP pickup (cleaning) and drop off (repair) steps are conducted in a system driven by an imposed flow and characterized by fluorescence microscopy. To evaluate and optimize the efficiency of this NP transportation process, the effect of both the chemical composition of the polymer surfactant and the NP surface chemistry is investigated. Interfacial interactions proved enabling for these NP transportation processes, specifically those involving NP/droplet, NP/substrate, and droplet/substrate interactions. Ultimately, droplets capable of both picking up and dropping off NPs are realized by adjusting fluid/fluid and fluid/substrate interactions, with electrostatic interactions between NPs and droplets proving most effective.
Phase‐Field Modeling of Electromechanical Breakdown in Multilayer Ceramic Capacitors
Authors: Cai Ziming , Wang Xiaohui , Li Longtu 
Published: December 2018

AbstractMultilayer ceramic capacitors (MLCCs) are drawing increasing attention in the application of energy storage devices due to their high volumetric capacitance and improved energy density. However, electromechanical breakdown always occurs, especially under high operation voltage, which limits their application in high‐voltage circuit. In this work, a phase‐field electromechanical breakdown model is developed to give a fundamental understanding on the coupled electromechanical effect on the dielectric breakdown of MLCCs. The thickness‐dependent dielectric breakdown strength is well simulated through this phase‐field model. It is found that the dielectric breakdown strength and the patterns of final breakdown path is significantly influenced by the defect concentration and applied stress. An enhanced breakdown strength of MLCC is proved under either compressive or shear stress state. The model not only provides a mechanistic understanding toward the electromechanical breakdown in MLCCs, but also applies to all kinds of dielectrics and serves as guidance toward the design of high‐voltage dielectrics.
Layered Hybrid Perovskites for Highly Efficient Three‐Photon Absorbers: Theory and Experimental Observation
Authors: Lu Shunbin , Zhou Feng , Zhang Qi , Eda Goki , Ji Wei 
Published: December 2018

AbstractMultiphoton absorption may find many technological applications, such as enhancing the conversion efficiency of solar cells by the utilization of sub‐band‐energy photons, below‐bandgap photodetection through the simultaneous absorption of several infrared photons for photocurrent generation, or light frequency upconversion for high‐resolution, 3D imaging. To enhance multiphoton absorption in semiconducting materials, one of the strategies is to explore low‐dimensional excitons. Here, a quantum perturbation theory on a giant enhancement in three‐photon absorption (3PA) arising from 2D excitons in multilayered crystals of organic–inorganic hybrid perovskites is presented. The maximal 3PA coefficient is predicted to be in the range of 2–7 cm3 GW−2 at 1100 nm, the largest values reported so far for any 2D and bulk semiconductors at room temperature. Excellent agreement between theory and the experimental findings unambiguously demonstrates a pivotal role in the enhancement of 3PA played by 2D excitons. The theory predicts that the resonant 3PA coefficient should be enhanced further by at least two orders of magnitude with very low temperature. The findings are essential for understanding giant 3PA arising from 2D excitons in layered hybrid perovskites and may open new pathways for highly efficient conversion from infrared light energy to either electrical energy or higher‐frequency light emission/lasing.

Published: December 2018

AbstractMethods and materials to manage interfaces between organelles and nonbiological functional materials have the potential to impart organelles with new and enhanced functions. Here, a hybrid bio‐photoelectrochemical system is designed by incorporating a cationic poly(fluorene‐co‐phenylene) conducting polymer (PFP) and thylakoids onto electrodes. PFP plays a critical role in boosting the efficiency of light energy conversion from the overall photoelectrochemical response. The positively charged side chains of PFP promote electrostatic binding with thylakoids, thereby improving the interfacial contact to the charge‐collecting electrode. Furthermore, the optical absorption band of PFP is complementary to the absorption profile of thylakoids. Light utility efficiency is therefore increased through a process of energy transfer. Moreover, the redox potential of PFP matches well with that of the protein complexes in electron transport chain, which facilitates electron‐transfer process from thylakoids to electrode. This combination of effects leads to a greater than 200% increase in the efficiency of water oxidation to oxygen. Under white light irradiation (350–800 nm, 50 mW cm−2), the photoelectric response of PFP/thylakoid electrode exhibits a photocurrent density of 1246 ± 41 nA cm−2, which is enhanced by approximately four times compared to that of the electrode modified only with thylakoid.
MXene—Conducting Polymer Asymmetric Pseudocapacitors
Authors: Boota Muhammad , Gogotsi Yury 
Published: December 2018

AbstractConducting polymers (CPs) are attractive pseudocapacitive materials which show the highest capacitance under positive potentials in aqueous protic electrolytes. One way to expand their voltage window (thus energy density) in aqueous electrolytes is to manufacture asymmetric supercapacitors using distinctly different anodes. However, CPs lack matching pseudocapacitive anode materials that can perform well in protic electrolytes (e.g., sulfuric acid). 2D titanium carbide (Ti3C2Tx), MXene, as a universal pseudocapacitive anode material for a range of CPs, such as polyaniline, polypyrrole, and poly(3,4‐ethylenedioxythiophene) deposited on reduced graphene oxide (rGO) sheets, is reported here. All‐pseudocapacitive organic–inorganic asymmetric devices with MXene cathodes and rGO–polymer anodes can operate in voltage windows up to 1.45 V in 3 m H2SO4. Most importantly, these devices show outstanding cycling performance, outperforming many reported asymmetric pseudocapacitors.

Published: December 2018

ABSTRACTCuS‐functionalized cellulose based aerogel (CBA) with 3D macroporous structure was synthesized by in situ deposition of visible light responsive CuS photocatalyst. Hexagonal CuS was deposited onto the outer and inner walls of CBA matrix. CuS/CBA composite catalyst has hierarchical porous structure and abundance in functional groups supporting CuS on CBA surface that enhance photodecomposition of methylene blue (MB). The CuS/CBA composite was characterized by XRD, FTIR, SEM‐EDS, Atomic Absorption Analysis, and XPS analysis. Photodegradation rate of MB by CuS/CBA composite catalyst in visible light was 94.1%, whereas, 67.4% for pure CuS. Initial MB concentration effects, pH change, and variations in CuS/CBA dosage on overall reaction kinetics were also studied. CuS/CBA composite catalyst carried out Photo‐Fenton like reactions which decomposed 97% MB within 6 min, by producing hydroxyl radicals from chemical and photocatalytic reactions. CuS/CBA composite catalyst was recycled and reused. It retained over 80% MB degradation rate even after five consecutive cycles. CuS/CBA composite can be used as biocatalyst for removal of organic dyes. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47404.
Torque tracking control of electric load simulator with active motion disturbance and nonlinearity based on T‐S fuzzy model
Authors: Li Chengcheng , Pan Xudong , Wang Guanglin 
Published: December 2018

AbstractThis paper develops a high performance nonlinear control method for an electric load simulator (ELS). The tracking performance of the ELS is mainly affected by the actuator's active motion disturbance and friction nonlinearity. First, a nonlinear model of ELS is developed, and then the Takagi‐Sugeno fuzzy model is used to represent the friction nonlinearity ofthe ELS. A state observer is constructed to estimate the speed of the load system. For converting the tracking control into a stabilization problem, a new control design called virtual desired state synthesis is proposed to define the internal desired states. External disturbances are attenuated based on an H∞criterion and the stability of the entire closed‐loop model is investigated using the well‐known quadratic Lyapunov function. Meanwhile, the feedback gains and the observer gains are obtained separately by solving a set of linear matrix inequalities (LMIs). Both a simulation and experiment were performed to validate the effectiveness of the developed algorithm.

Published: December 2018

AbstractWound healing is a basic biological process including proliferation and migration of keratinocyte. The effects of microRNAs on skin wound healing remain largely unexplored. This study aimed to investigate the role of microRNA‐126 (miR‐126) in human skin wound healing. Relative expression of miR‐126 after injury was evaluated by qRT‐PCR. Cell viability, colony formation, cycle distribution, migration, and the alternation of PI3 K/AKT pathway after miR‐126 knockdown or overexpression were detected, respectively. In addition, potential target gene of miR‐126 was also explored by luciferase assay. Results showed that miR‐126 was up‐regulated during skin wound healing. Moreover, overexpression of miR‐126 promoted cell proliferation and migration, whereas inhibition of miR‐126 led to the opposite effects. Additionally, we discovered that PLK2, which inhibited cell viability, colony formation and migration of keratinocyte, was a target gene of miR‐126. The expression of PLK2 was negatively correlated with the level of miR‐126 during wound healing. Finally, we demonstrated that overexpression of miR‐126 significantly increased the expression of p‐AKT, p‐ERK2, and PI3 K, indicating that overexpression of miR‐126 activated PI3 K/AKT signaling pathway. In conclusion, our results demonstrated that miR‐126 acted as a critical regulator for promoting proliferation and migration in keratinocyte during skin wound healing.

Published: December 2018

AbstractDetection of heroin use is an important task in clinical drug testing and can be best performed by using 6‐acetylmorphine as the target analyte. This study was performed to evaluate an on‐site test for 6‐acetylmorphine screening in urine with an assigned cut‐off limit at 10 ng/mL. The reference method was a forensic accredited liquid chromatography–tandem mass spectrometry method. The study confirmed that negative controls and negative authentic specimen resulted in negative readings. Low cross‐reactivity was recorded from other potential interfering opioids. Prepared standards and commercial calibrators demonstrated that the cutoff level of the test was lower than the assigned value and rather 2 ng/mL. A study using authentic specimens from patients on substitution treatment with methadone, morphine, and buprenorphine confirmed that the real cut‐off level was 2 ng/mL. Using this value as cutoff limit the sensitivity and specificity of the test was 100%.
Increasing the amount of phosphoric acid enhances the suitability of Bradford assay for proteomic research

Published: December 2018

AbstractThe Bradford assay is one of the most commonly used methods for protein quantification. However, in proteomic research, the lysis buffer generally used for dissolving proteins can cause some interference to the assay. The dye reagent of classical Bradford assay contains 8.50% (w/v) phosphoric acid, which is an important factor relating to the color yield of the assay. In this study, the phosphoric acid content in dye reagent was increased to 9.35% (w/v), 10.20% (w/v), and 11.05% (w/v) to evaluate the changes of interference and the effects of lysis buffer on the interaction between proteins and dye reagent. Results show that lysis buffer not only causes background interference but also affects the protein–dye chromogenic process. Analysis of different components in the lysis buffer showed that carrier ampholyte is the main factor that introduces interference to the Bradford assay. Detergents are well‐known interfering compounds in the Bradford assay, but CHAPS and octyl b‐D‐glucopyranoside only cause slight interference. When the amount of phosphoric acid was increased from 8.50%(w/v) to 10.20% (w/v), the sensitivity of the Bradford assay to proteins in lysis buffer was increased, and the interference delivered by lysis buffer was considerably reduced.
