The anodic behavior of coldrolled lowcarbon steel in the aqueous STPP solution with aluminum hydroxide, borax, and glycerin additives at room temperature has been studied.It was revealed that the potentiodynamic curves that characterize the anodic behavior of steel st05kp samples shows up to three passivation platea…
Above a certain solid fraction, dense granular suspensions in water exhibit non-Newtonian behavior, including impact-activated solidification. Although it has been suggested that solidification depends on boundary interactions, quantitative experiments on the boundary forces have not been reported. Using high-speed vi…
The research aims to study the mechanical properties included impact strength and flexural strength of composite materials consists of epoxy resin with phenolic formaldehyde resin reinforced by graphite or silica particles or both, and reinforced with carbon fibers of a standard format (-90, 0, +90). The results obtai…
Abstract Reactivity of monolayer protected atomically precise clusters of noble metals is of significant research interest. To date very few experimental data are available on the reaction thermodynamics of such clusters. Here we report a calorimetric study of the reaction of glutathione (GSH) protected silver cluster…
Uranium oxide is central to every stage of the nuclear fuel cycle, from mining through fuel fabrication and use, to waste disposal and environmental cleanup. Its chemical and mechanical stability are intricately linked to the concentration of interstitial O atoms within the structure and the oxidation state of U. We h…
High resolution size exclusion chromatography (SEC) coupled with static light scattering (SLS) analyses were conducted to study the effect of the mobile phase ionic strength and protein concentration on the output of SEC experiments. The results highlight the effect of small changes in the mobile phase composition on…
This paper reports on the magnetic properties and electromagnetic characterization of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8). The La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8) materials were prepared using a mechanical alloying method.
The stability of large ligated copper(I) clusters of undeca- and dodecanuclearity encapsulating iodide and stabilized by dithio- and diseleno-phosph(in)ates was investigated by density functional theory (DFT) calculations. A bonding analysis is provided, which shows strong iono-covalent bonding between the iodide and…
A series of experimental studies was carried out to investigate the influences of pre-torsion on microstructure evolution, mechanical properties, and fracture appearance of pure titanium subjected to subsequent tension deformation. An introduction of pre-torsion strain can improve the materials’ mechanical properties…
The effects of seven constituent phases—CeNi3, NdNi3, Nd2Ni7, Pr2Ni7, Sm5Ni19, Nd5Co19, and CaCu5—on the gaseous phase and electrochemical characteristics of a superlattice metal hydride alloy made by induction melting with a composition of Sm14La5.7Mg4.0Ni73Al3.3 were studied through a series of annealing experiments…
Abstract Two-dimensional (2D) copper chalcogenides (Cu 2− x X where X = S, Se, Te) have had much attention regarding various applications due to their remarkable optical and electrical properties, abundance, and environmentally friendly natures. This work indicates that highly uniform Cu 2− x S (where 0 < x < 1)…
Witherite [BaCO 3 ] and norsethite [BaMg(CO 3 ) 2 ] are perceived as chemical and structural analogs of aragonite [CaCO 3 ] and dolomite [CaMg(CO 3 ) 2 ], respectively. However, norsethite, unlike dolomite, readily precipitates from aqueous solutions at ambient conditions. This is of special interest as the dehydratio…
Abstract Cancer is a global epidemic that significantly affects all ages and socioeconomic groups. One of the great difficulties of cancer is its diagnosis, mainly in the initial phase. Currently, the most used and effective technique for cancer diagnosis is Magnetic Resonance Imaging (MRI). For a better visualization…
A simple route is described to synthesize cross-linked polyamides (cPAs) with excellent mechanical properties at mild conditions through a Michael addition reaction coupled with bulk polycondensation. A Michael addition of methyl acrylate with 1,6-hexanediamine was conducted in a bulk state at a N–H/C═C molar ratio of…
Low-density polyethylene (LDPE) has caused serious environmental damages, and it has been a challenge for waste management in large cities. The LDPE recycling as composites with natural fibers such as sugarcane fibers (SCF) has been an interesting alternative to conciliate economic aspects with environmental benefits.…
Collagen and its denatured form, gelatin, are biopolymers of fundamental interest in numerous fields ranging from living tissues to biomaterials, food, and cosmetics. This study aims at characterizing mixtures of those biopolymers at high concentrations (up to 100 mg·mL –1 ) at which collagen has mesogenic properties.…
ABSTRACT Novel hypercrosslinked microporous organic polymers (MOPs) derived from N‐functionalized siloles as basic building units have been designed and synthesized via Friedel–Crafts alkylation reaction. The resulting N‐functional silole‐containing polymer networks exhibit high thermal stabilities and moderate Brunau…
It is a highly desirable goal of researchers to develop effective biomaterials with minimum recovery time and affordable treatment expense for tissue engineering and drug delivery. In this scenario, numerous synthetic and natural polymers have been used. Among those synthetic polymers, polyorganophosphazenes (POPs) ha…
Abstract The synthesis of three new isocyanurate derivatives 2‐X (X=NO 2 , H, NMe 2 ) with azobenzene arms terminated by various X substituents is reported, and their linear and nonlinear absorption properties are studied. It is shown that mixtures that contain increased contents of cis ‐azo isomers can be reversibly…
We report an efficient screening methodology based on the capillary counter-diffusion technique (CCD), which was evaluated using two different practical approaches. The first consisted of kits prepared with the most successful crystallizing agents (PEG and ammonium sulfate) buffered at different pHs ranging from 4 to…
