RACK1 is a member of the WD repeat family of proteins and is involved in multiple fundamental cellular processes. An intriguing feature of RACK1 is its ability to interact with at least 80 different protein partners. Thus, the structural features enabling such interactomic flexibility are of great interest. Several pr…
Helical core–satellite nanoarchitectures of AgNR@Cys@AuNPs have been successfully fabricated by self-assembly of Ag nanorods and Au nanoparticles, using l - and d -cysteine as bridging molecules, respectively. The chirality of the nanoarchitectures is confirmed by circular dichroism spectroscopy, and the results sugge…
Conductance fluctuation of edge-disordered graphene nanoribbons (ED-GNRs) is examined using the non-equilibrium Green's function technique combined with the extended Hückel approximation. The mean free path λ and the localization length ξ of the ED-GNRs are determined to classify the quantum transport regimes. In the…
A molecular-statistical theory is developed, which enables one to describe the nematic-isotropic phase transition in liquid crystals doped with spherical nanoparticles taking into account the effects of phase separation. It has been shown that in the case of strong interaction between nanoparticles and mesogenic molec…
A fluid self-assembly sphere phase (SP) of liquid crystal induced by chiral dopant is observed in a narrow temperature range between isotropic and blue phase or between isotropic and chiral nematic phase. The SP consists of three-dimensional twist spheres (3-DTSs) and disclinations among 3-DTSs. The temperature range…
An important role of garments is to provide adequate comfort. A study was undertaken of the sensory scores for perceived comfort of wool base layer long sleeve knitted T shirts. This paper, the first in a series, describes and evaluates the wearer trial protocol in which untrained female wearers scored tactile, therma…
Vertical magnetization shift (MShift) coexisting with the conventional exchange bias fields was observed in the epitaxial bilayers of the ferromagnetic SrRuO3 and the G-type antiferromagnetic La0.3Sr0.7FeO3 grown on SrTiO3(111) substrate. We demonstrate this MShift can be tuned from 5% to 36% by controlling the SrRuO3…
As walking robots are requested to perform tasks in rough terrain, the development of actuators capable to flexibly adapt to the unstructured environment becomes more and more necessary. The conventional mechanisms with stiff joints make the robots more complex, heavy, large and expensive. Shape Memory Alloys are a ca…
A formaldehyde-free flame retardant (EFFR) for bamboo viscose fabric was synthesized by raw materials of silanol, phosphorus pentoxide, and diethanolamine. The flame retardant had the dual function of imparting fire resistance and softness to bamboo viscose fabric; moreover, it had no halogen and free formaldehyde, an…
This paper presents our work on electrical characterization of metal-ferroelectric-oxide-semiconductor (MFeOS) and metal-ferroelectric-nitride-semiconductor (MFeNS) structures for nonvolatile memory applications. Thin films of lead zirconate titanate (PZT: 35:65) have been used as ferroelectric material on 2.5–5 nm th…
The dependence of the magnetostrictive properties of cobalt ferrite on the size distribution of the powder used in deriving the samples from traditional ceramic approach is presented. Sample obtained by combining the smallest and largest particle size distributions gave the highest magnetostriction and strain sensitiv…
Here, we report field emission (FE) properties of a chemical vapor deposited individual graphene investigated by in-situ transmission electron microscopy. Free-standing bilayer graphene is mounted on a cathode microprobe and FE processes are investigated varying the vacuum gap of cathode and anode. The threshold field…
ABSTRACT The 2‐N‐thiosemicarbazide‐6‐O‐hydroxypropyl chitosan (ATU‐HPCS) was prepared by chitosan grafted hydroxypropyl and thiosemicarbazide through the method of “amino protection‐graft‐deprotection,” while the ATU‐HPCS gel membranes were obtained from gelatin and polyvinyl pyrrolidone as additives, and the ATU‐HPCS…
The 1111-type iron arsenide hydride CaFe${}_{1\ensuremath{-}x}$Co${}_{x}$AsH was synthesized by high-pressure solid-state reaction, and its electronic structure and superconducting properties were investigated. Bulk superconductivity was observed at $x$ = 0.09--0.26. A maximum superconducting critical temperature (${T…
For optical waveguides with high index-contrast and sharp corners, it is challenging to develop efficient, accurate and general full-vectorial mode solvers. The classical mode-matching method is capable of computing modes to high accuracy for waveguides with right-angle corners, but it is not convenient to implement w…
An automated multi-pumping flow system is proposed for the chemiluminometric determination of ascorbic acid in pharmaceutical formulations, relying on the ability of semiconductor nanocrystals to generate short-lived reactive species upon photo-irradiation. A photo-unit based on visible-light-emitting diodes is used t…
The translational symmetry breaking of a crystal at its surface may form two-dimensional (2D) electronic states. We observed one-dimensional nonlinear optical edge states of a single atomic membrane of molybdenum disulfide (MoS2), a transition metal dichalcogenide. The electronic structure changes at the edges of the…
Poly(isobutyl methacrylate) (PiBMA) polymer doped in pure p‐Ethoxybenzylidene p‐Heptylaniline (EBHA) mesomaterial has been investigated in the present study. The dielectric and electro‐optical parameters of EBHA having nematic phase were altered due to the addition of polymer in different concentration. The strong dop…
GeTe is a well-know prototypical phase change material, while pure Sb is described as a material with strong resonant bonding properties which are indicative of a fast switching phase change material. We have studied the crystallization times and crystallization temperatures of phase-change materials along the GeTe-Sb…
A chemical method for in situ synthesis of copper nanoparticles on SBA-16 silica spheres under ambient conditions has been reported. The silica support has been introduced into copper precursor solution before chemical reduction. Metal ions diffuse into mesopores (pore diameter 5–7 nm) of silica where in situ reductio…
