A novel amphiphilic chitosan derivative of N,N-dimethylhexadecyl carboxymethyl chitosan (DCMCs) was synthesized. The structure of DCMCs was confirmed via FT-IR and (1)H NMR, and the critical micelle concentration (CMC) was investigated by fluorescence spectroscopy. The results indicated that DCMCs has hydrophilic carb…
The initial step of O 2 evolution reaction on a TiO 2 surface is a long-standing puzzle. A recent scanning tunneling microscopy experiment showed that the H 2 O molecule adsorbed on rutile TiO 2 (110) surface could decompose under ultraviolet illumination (Tan, S. J.; et al. J. Am. Chem. Soc ., 2012, 134, 9978). The u…
Docking algorithms that aim to be applicable to a broad range of ligands suffer reduced accuracy because they are unable to incorporate ligand-specific conformational energies. Here, we develop a set of Carbohydrate Intrinsic (CHI) energy functions that quantify the conformational properties of oligosaccharides, based…
The self-assembly of the amyloid-β (Aβ) peptide of 39-43 amino acids into senile plaques is one hallmark of Alzheimer's disease (AD) pathology. While A2 V carriers remain healthy in the heterozygous state, they suffer from early onset AD in the homozygous state. As a first toward understanding the impact of A2 V on Aβ…
The silver surface plasmon resonance (SPR) sensor has long been explored due to its intrinsic sensitivity enhancement over the conventional single-layered gold SPR sensor. However, the silver SPR sensor has not been exploited for practical applications because of pronounced instability problems. We propose a novel gol…
We report the chemical fabrication of metallic glass nanoparticles (MG-NPs). Using commercially available Pd, Ni, and P precursors, size-controlled amorphous Pd–Ni–P NPs were obtained by a one-pot solvothermal synthesis procedure. Differential scanning calorimetry identified typical MG properties of the unsupported Pd…
Nylon 11,11 is a new odd–odd polyamide with multiple crystalline structures. The wide‐angle X‐ray scattering indicated that the structure of quenched sample was not amorphous but a γ‐form crystal with a relatively low crystallinity. The α‐form and the γ‐form crystal of nylon 11, 11 could be obtained by annealing the q…
The bicontinuous lyotropic liquid phases surrounded by the isotropic phase form monocrystals with well-developed facets. We investigate the structure and stability of the facets formed by the bicontinuous phase of Pn3̅m symmetry, at three preferred directions, which are developed on a spherical droplet of Pn3̅m phase…
Self‐hybrid thermoplastic composites (combination of two fiber sizes) were obtained by injection molding using pine or agave fibers with polypropylene (PP). The effect of self‐hybridization was determined through mechanical properties and water absorption for different total fiber contents between 10 and 30% wt. The r…
The crystallization of poly(lactic acid) (PLA) is usually slow and related to the content of d -lactide. A new approach is suggested in this work to accelerate the crystallization of PLA via the synergistic effect of nanofibril nucleating agent (dibenzylidene sorbitol, DBS), plasticizer (poly(ethylene glycol), PEG) an…
To commercially produce consumer products using engineering polymers, it is very important to control the physical properties of the material. However, quality control of the material is not easy because of many reasons such as cost reduction, cleaning issues, the use of scraps, etc. In many cases, even a small amount…
Electrochemical impedance spectroscopy was used to study the transport properties of the three-layer Dion–Jacobson phase HLa 2 Ti 2 TaO 10 in the temperature range of interest (250–475 °C) for intermediate temperature fuel cells. The compound was prepared by proton exchange of RbLa 2 Ti 2 TaO 10, which in turn was mad…
Tissue engineering is considered a promising future option for nasal cartilage repair. However, until now, an optimal material has not been identified for this specific purpose. Therefore, the aim of this study was to analyze a recently developed decellularized collagen matrix, which has promising material properties…
Tetraphenylethylene (TPE), an archetypal luminogen with aggregation-induced emission (AIE), was grafted to a salt-responsive peptide to yield a yet luminescent hydrogelator. After testing different parameters, we found that only in the presence of salt rather than temperature, pH, and solvent, did the monodisperse hyd…
One of the important characteristics of solid-state phase transformations in steels is the choreography of atoms as they traverse the frontier between the parent and the product phases. Some transformations involve a chaotic motion of atoms consistent with long-range diffusion, and hence are closer to equilibrium than…
The objective of this study was to investigate the role of the CeO2 nanoparticle (NP) surface charge and the presence of natural organic matter (NOM) in determining bioavailability and toxicity to the model soil organism Caenorhabditis elegans. We synthesized CeO2-NPs functionalized with positively charged, negatively…
Bare-metal stents (BMS) and drug-eluting stents (DES) are the two main categories of FDA-approved coronary stents in the market for treating atherosclerosis. Problems associated with BMS include in-stent restenosis due to intimal hyperplasia, leading to stent failure, while DES harbours a life-threatening complication…
Objectives: to analyze the cytogenetic parameters in vivo and in vitro in the administration of Resveratrol and Candesartan Cilexetil in different dosages and combinations. Material and methods. Male C57Bl/6 mice were used for the research. We investigated the molecular-biological parameters in vivo and in vitro and a…
An interaction can best be defined as a violent reaction that interrupts normal conditions. Interactions become apparent when there is an intense outcome created by chemical, thermal, or physical responses to the combination of two or more variables. These keywords were added by machine and not by the authors. This pr…
