Development, homeostasis and regeneration of tissues result from a complex combination of genetics and mechanics, and progresses in the former have been quicker than in the latter. Measurements of in situ forces and stresses appear to be increasingly important to delineate the role of mechanics in development. We revi…
An enduring impediment in the photocatalysis domain is the rapid recombination of photoinduced charge carriers. One viable strategy to realize efficient separation of photoinduced charge carriers is to design core/shell nanostructures. In this context, our work explains the substantial separation of photocarriers and…
Through coupled experimental analysis and computational techniques, we uncover the origin of anodic stability for a range of nonaqueous zinc electrolytes. By examination of electrochemical, structural, and transport properties of nonaqueous zinc electrolytes with varying concentrations, it is demonstrated that the ace…
Reaction of a ditopic urea "strut" (L1) with cis-(tmen)Pd(NO3)2 yielded a [3+3] self-assembled molecular triangle (T) [L1 = 1,4-di(4-pyridylureido)benzene; tmen = N,N,N',N'-tetramethylethane-1,2-diamine]. Replacing cis-(tmen)Pd(NO3)2 in the above reaction with an equimolar mixture of Pd(NO3)2 and a clip-type donor (L2…
Metal-halide semiconductors with perovskite crystal structure are attractive due to their facile solution processability, and have recently been harnessed very successfully for high-efficiency photovoltaics and bright light sources. Here, we show that at low temperature single colloidal cesium lead halide (CsPbX3, whe…
X-ray techniques have been used for more than a century to study the atomic and electronic structure in practically any type of material. The advent of correlated electron systems, in particular complex oxides, brought about new scientific challenges and opportunities for the advancement of conventional X-ray methods.…
Silicone elastomers are promising materials for dielectric elastomer transducers (DETs) due to their superior properties such as high efficiency, reliability and fast response times. DETs consist of thin elastomer films sandwiched between compliant electrodes, and they constitute an interesting class of transducer due…
Driving forces for association between oppositely charged biological or synthetic polymers in aqueous solution have long been identified as electrostatic in origin. This attraction is broken down into an entropic component, due to loss of counterions, and an enthalpic component, stemming from Coulombic attraction betw…
It is thought that KRAS oncoproteins are constitutively active because their guanosine triphosphatase (GTPase) activity is disabled. Consequently, drugs targeting the inactive or guanosine 5'-diphosphate-bound conformation are not expected to be effective. We describe a mechanism that enables such drugs to inhibit KRA…
Natural fibres are used since many centuries for different purposes since the beginning of civilization. They have been used for ropes, toughening of pots etc since many centuries. Natural fibers are of two types. Natural inorganic fibers such as Basalt, Asbestos etc and the other are the natural organic fibers such a…
In this study, physicochemical properties and the area of use of diatomites that occur in association with Central Anatolian volcanism in the Karacaren region (rgp country, Nevehir) are investigated. In the investigated area two stratigraphic sections were measured, one is in Quaternary lake units (K1) and another sec…
Cerium-doped 0.8BaTiO3-0.2Bi[Formula: see text]K[Formula: see text]TiO3with composition 0.8Ba0.2(Bi[Formula: see text]K[Formula: see text])Ti[Formula: see text]Ce[Formula: see text]O3where x = 0.01, 0.02, 0.03, 0.04, 0.05, 0.06 lead free ceramics were prepared by conventional solid state reaction method followed by hi…
A series of ceria-doped mesoporous TiO2 thin films with anatase phase are synthesized and used as the support of platinum catalysts for low-temperature catalytic combustion of methanol. Since the methanol combustion on the catalysts can usually generate local overheating, which unavoidably leads to the structure destr…
We study the formation of bands of colloidal particles driven by periodic external fields. Using Brownian dynamics, we determine the dependence of the band width on the strength of the particle interactions and on the intensity and periodicity of the field. We also investigate the switching (field-on) dynamics and the…
We have computationally investigated the use of the multisegment, multiaddition, plug-flow crystallizer (MSMA-PFC) for use in producing pharmaceutical crystals. A population balance framework was used to model the crystallization process. The dissolution of crystals can be modeled when solubility is below saturation.…
Abstract. This paper presents a free and open-source program called PyXRD (short for Python X-ray diffraction) to improve the quantification of complex, poly-phasic mixed-layer phyllosilicate assemblages. The validity of the program was checked by comparing its output with Sybilla v2.2.2, which shares the same mathema…
Gradient metasurfaces have recently emerged as a powerful tool for the control of externally incident optical wavefronts. Here we present a theoretical study showing how they can also dramatically modify the radiation properties of light emitters located in their near-field zone. First, the spontaneous emission decay…
Abstract The aim of the work was to develop a mathematical model for computing the steady-state voltage – current characteristics of a planar Solid Oxide Fuel Cell and to determine the performance of a new SOFC design. The design involves cross-flow bipolar plates. Each of the bipolar plates has an air channel system…
Hierarchically structured composite of polypyrrole (PPy) and 1,4-naphthoquinone (NQ) was prepared by incorporation of the guest redox-active organic molecule NQ in the host redox-active conductive polymer PPy. The composite and its hierarchical structure induced enhanced electrochemical performances as a redox capacit…
Abstract Aerosol‐assisted chemical vapour deposition of substituted polyoxometalates H4[PMo11VO40], H7[PMo8V4O40], [nBu4N]4[PVW11O40] and [nBu4N]5[PV2W10O40] resulted in the formation of vanadium‐doped metal oxide thin films. Depositions were carried out at 550 °C in methanol or acetonitrile for the POMs that containe…
