The silk protein fibroin is a wondrous biopolymer widely used to form structures that interface with biological entities. In addition to tissue scaffolds, sponges, and films, biochemically modified fibroins can be used in conjunction with techniques such as photolithography and soft lithography to expand their reperto…
A critical challenge in using thermoelectric generators (TEGs) for charging the portable or wearable electronics has been their limited outputs, as available temperature differential on human body (∆ T ext ) is typically less than 10 K. Furthermore, the thermal resistance ( R th ) at the TEG–air interface often overwh…
Elastomer foams based on EVA, PU, and EVA/PU blends formulated for shoe‐sole applications were prepared by a supercritical N 2 batch foaming process and characterized for physicomechanical, friction and abrasion properties. The blending of EVA with PU was aimed for improving the friction and wear characteristics of th…
The balance injection of holes and electrons into a thin emissive quantum dot (QD) layer for efficient radiative recombination is critical to the color purity, stability, and efficiency of the QD‐based light‐emitting diodes (QD‐LEDs). Due to the difficulty of charge injection into wide band gap blue QD layer, the perf…
In order to investigate the roles of active molecules during the bioinspired synthesis process of gold nanoparticles by Cacumen platycladi leaf extract, flash column chromatography was employed to separate the Cacumen platycladi leaf extract according to the polarity differences. Fourier transform infrared spectroscop…
In this study, a new broadband and conformal metamaterial absorber using two flexible substrates was proposed. Simulation results showed that the proposed absorber exhibited an absorption band from 6.08 to 13.04 GHz and a high absorption of 90%, because it was planar. The absorber was broadband as its relative absorpt…
The present work reports on a new strategy for fabrication of mechanically stable and environmental‐friendly superhydrophobic surfaces. First, a novel cost‐effective approach is developed to synthesize superhydrophobic SiO 2 (SH‐SiO 2 ) nanoparticles at room temperature through the reaction between the surface reactiv…
In this paper, we carry out a rigorous error analysis for a finite-element discretization of the linear, weakly coupled energy stable scheme introduced by Shen and Yang for a Cahn-Hilliard phase-field model of two-phase incompressible flows with matching density.
Mycothiol (MSH) is the major low molecular weight (LMW) thiol in Actinomycetes. Here, we used shotgun proteomics, OxICAT and RNA-seq transcriptomics to analyse protein S-mycothiolation, reversible thiol-oxidations and their impact on gene expression in Mycobacterium smegmatis under hypochlorite stress. In total, 58 S-…
Transparent nanoparticle-based liquid marbles with high gas-permeability are prepared to culture tumor spheroids in 3D without the need of supplementary growth factor. The culturing process of spheroids from a population of cancer cells or a single cell in the transparent liquid marbles can be optically recorded conti…
A variable temperature neutron diffraction study of the novel oxide ion conductor Ba 3 MoNbO 8.5 has been performed between 25 and 600 °C. Nonmonotonic behavior of the cell parameters, bond lengths, and angles are observed indicating a structural rearrangement above 300 °C. The oxygen/vacancy distribution changes as t…
The interface between metal and reducible oxide has attracted increasing interest in catalysis. The FeO x –Pt interface has been a typical example, which showed remarkable activity for the preferential oxidation of CO (PROX) at low temperatures. However, model catalytic studies under vacuum conditions or in high-press…
Metasurfaces, 2D artificial electromagnetic media, open up a new frontier of functional device design ranging from radio waves to the visible region. Particularly, metasurface‐based lenses are indispensable in various practical terahertz applications. The authors aim at achieving flexible and robust metalenses for eff…
In this paper, we have developed a one-step thermal treatment of polydimethylsiloxane (PDMS) liquid to create transparent super-repellent surface (TSS) and super-repellent powder. They are super-repellent toward water and ethylene glycol. During the one-step thermal treatment, PDMS soot is generated and deposited onto…
Abstract In this contribution, first synthesis of semiconducting ZnSiN 2 and ZnGeN 2 from solution is reported with supercritical ammonia as solvent and KNH 2 as ammonobasic mineralizer. The reactions were conducted in custom‐built high‐pressure autoclaves made of nickel‐based superalloy. The nitrides were characteriz…
Based on direct sucrose conversion, the bacterium Burkholderia sacchari is an excellent producer of the microbial homopolyester poly(3-hydroxybutyrate) (PHB). Restrictions of the strain's wild type in metabolizing structurally related 3-hydroxyvalerate (3HV) precursors towards 3HV-containing polyhydroxyalkanoate (PHA)…
A multifocal metalens, which focuses incident light at multiple foci, has many applications in imaging systems and optical communications. However, the traditional design strategy of a multifocal metalens combines several lenses that have different focal points into a planar integrated unit, resulting in low imaging q…
Lignocellulose from fast growing hardwood species is a preferred source of polysaccharides for advanced biofuels and “green” chemicals. However, the extensive acetylation of hardwood xylan hinders lignocellulose saccharification by obstructing enzymatic xylan hydrolysis and causing inhibitory acetic acid concentration…
We investigate the drying process of three-component and polydisperse colloidal suspensions using Brownian dynamics simulations. We have previously reported (Phys. Rev. Lett. 2016, 116, 118301) on the drying of binary mixtures. For binary mixtures, we found that a gradient of colloidal osmotic pressure develops during…
Polyhydroxyalkanoates (PHAs) are natural polyesters of increasing biotechnological importance that are synthesized by many prokaryotic organisms as carbon and energy storage compounds in limiting growth conditions. PHAs accumulate intracellularly in form of inclusion bodies that are covered with a proteinaceous surfac…
