Amphiphilic biopolymers such as hydrophobically modified chitosan (hmC) have been shown to convert liquid blood into elastic gels. This interesting property could make hmC useful as a hemostatic agent in treating severe bleeding. The mechanism for blood gelling by hmC is believed to involve polymer–cell self-assembly,…
Most of the available thermodynamic data concerning radioactive waste disposal are restricted to values of reaction equilibrium constants (logK298°) at 25 °C and 1 bar. Simple estimation methods such as isocoulombic reactions can be used for extrapolating the properties of reactions involving aqueous species and miner…
Acellular scaffolds from decellularized donor organs are showing promising clinical results in tissue and organ repair and regeneration. A successful decellularization process is determined by (a) its capability to decellularize complete organs of large animals, (b) retention of the extracellular matrix (ECM) structur…
Spinodal decomposition in thermally aged Fe–Cr alloys leads to significant hardening, which is the direct cause of the so-called 475∘C-embrittlement. To illustrate how spinodal decomposition induces hardening by atomistic interactions, we conducted a series of numerical simulations as well as reference experiments. Th…
Abstract Multi‐dimensional materials can combine the advantages of fast mass diffusion of high dimensional structures and advanced intrinsic properties of low dimensional substructures. In specific, superstructures are widely prepared from assembling low dimensional materials into arrays by complicated methods. We rec…
Water contamination via poisonous heavy-metal ions, above all Pb 2+, has been a great universal concern leading to severe hazards to human health. Today, creating novel adsorbents with the ability to chelate these ions with a high decontamination potential is of great interest. In this work, we targeted the design of…
The reduction of C═C is of great importance, while H 2 is the most widely used source usually in the harsh condition in the industry. However, under mild conditions, the H 2 -free reduction of C═C bonds to more valuable products is one of the challenges to be solved in recent years. Herein, ZnCr-layered double hydroxi…
Protonated g-C3N4/MoS2 heterojunction with enhanced photocatalytic activity was prepared by treating g-C3N4/MoS2 with formic acid and using a hydrothermal method. The microstructure and morphology of the heterojunctions were analysed by XRD, FTIR, SEM, TEM, and XPS technology, respectively. The photodegradation experi…
This study presents a chemotaxonomic investigation of the genus Bostrychia through the quantitation of the major mycosporine-like amino acids (MAAs). The presence of some cryptic species had been suggested in the B. moritziana/B. radicans complex and MAA-profiling in respective samples revealed different chemotypes wi…
Crystal phase structure of bimetallic alloy is an important factor determining the electrocatalytic activity toward oxidation of energy molecules. In this paper, PdCu bimetallic NPs with similar element composition and different crystal phase structural features have been synthesized hydrothermally by adjusting the co…
Although bimetallic materials with various structures have been used as anodes for advanced lithium ion batteries, structural degradation, caused during electrochemical reactions, leads to a shorter cycle lifespan. Herein, we propose a rational structural design, carbon-wrapped porous bimetallic nickel–antimony nanosh…
Advances in renewable energy recourses technologies have paved the way for increased utilization of DC grids in modern power systems. In particular, high voltage DC (HVDC) transmission cables are used to harvest offshore energy. Since failure diagnosis and repair of the buried offshore cables under the sea bed involve…
Local drug injection therapy for tumor site, as a neoadjuvant chemotherapy method, shows important significance in clinical application; however, it obtains unsatisfying therapeutic effect due to the serious toxic and side effect in normal tissues caused by drug diffusion or complexity of the preparation. In this arti…
We report results of muon spin relaxation and rotation ($\ensuremath{\mu}\mathrm{SR}$) experiments on the spin-liquid candidate ${\mathrm{YbMgGaO}}_{4}$. No static magnetism $\ensuremath{\gtrsim}0.003{\ensuremath{\mu}}_{B}$ per Yb ion, ordered or disordered, is observed down to 22 mK, a factor of 2 lower in temperatur…
The distribution and dissipation of neutral atoms are crucial for understanding the dielectric recovery process after interrupting direct current (DC) vacuum arcs. This article aims to investigate the dissipation of copper atoms after a forced extinction of the vacuum arc experimentally, adopting the plane laser-induc…
Abstract Whether a metallic material fractures by brittle cleavage or by ductile rupture is primarily governed by the competition between cleavage and dislocation emission at the crack tip. The linear elastic fracture mechanics (LEFM) based criterion of Griffith, respectively the one for dislocation emission of Rice,…
The aim of this study was to assess the possibility of using furniture waste for smokeless fuel production using the pyrolysis process. Four types of wood-based wastes were used in the pyrolysis process: pine sawdust (PS), chipboard (CB), medium-density fiberboard (MDF), and oriented strand board (OSB). Additionally,…
Armature design plays a significant role in determining the performance of an induction coilgun. In this article, aluminum projectiles of 10.5-mm length and 21.7-mm outer diameter but of different shapes and thicknesses are fired from different initial positions inside the barrel having an outer diameter of 25 mm and…
Abstract An effective approach for fast synthesis of well‐defined star‐shaped poly(2‐methyl‐ N ‐tosylaziridine)s was developed by one‐pot tandem ring‐opening polymerization (ROP) of N ‐sulfonyl aziridines with trimethylsilyl azide (TMSN 3 ) and “click” reaction with alkynes. Azido terminated polyaziridines ( α ‐N 3 ‐P…
Fast 1 H magic-angle spinning (MAS) solid-state NMR spectroscopy was utilized for quantitative analysis of the linker composition and spatial arrangement of functional groups of MTV-UiO-66–(BDC–CH 3 ) x –(BDC–OH) y –(BDC–NH 2 ) 1– x − y . 2D 1 H– 1 H DQ–SQ MAS NMR experiments facilitate the 1 H NMR chemical shift assi…
