Summary The suppression effects of Ammonium Polyphosphate (APP) with different mass fractions on the maximum explosion pressure (Pmax), the explosibility index (Kst), the minimum ignition energy (MIE) and the minimum ignition temperature (MIT) of unsaturated polyester resin (UPR) dust were studied. Results indicated t…
Abstract A combinatorial approach was applied to devise a set of reference Si–C–O–H species that is used to derive group‐additivity values (GAVs) for this class of molecules. The reference species include 62 stable single‐bonded, 19 cyclic, and nine double‐bonded Si–C–O–H species. The thermochemistry of these referenc…
To clarify the element partitioning behavior between minerals and aqueous chloride solutions, we conducted experiments to investigate simultaneous partitioning of Ni2+, Mg2+, Co2+, Zn2+, Fe2+, and Mn2+ ions between alabandite (MnS) and 1 mol/L (Ni, Mg, Co, Zn, Fe)Cl2 aqueous solutions at 500–800 °C and 100 MPa. The bu…
The present study deals with the gel formation tendency in the ternary TeO2-TiO2-ZnO system. Depending on the TiO2 amount, the gelation occurred at different times and subsequently several gel formation regions have been determined. Homogeneous, transparent and monolithic gels were obtained using combination of organi…
Abstract X-ray diffraction analysis and ultrasonic measurements of a glass with the pyrope composition were conducted to determine its structural and elastic properties at pressures from 1 atm to 12.9 GPa. Our results indicate that its structural evolution is closely related to changes in the compression wave velocity…
We present two configurations for analog 0 to 2\ensuremath{\pi} optical phase modulation using liquid crystals (LCs), each of which achieve switching times that are 1 ms or less. One configuration is based on the switching behavior of a so-called nematic pi cell, and the other is based on the flexoelectro-optic effect…
Abstract For portable and wearable electronics, a flexible full battery can lead to tremendous development. However, certain issues with the anode still exist, such as complexity, low capacity, and poor stability. Herein, a flexible metal oxide (MOx) composite anode is synthesized in situ, which transfers a stainless‐…
Abstract Carbonic anhydrase IX (CA IX), a tumor‐associated metalloenzyme, represents a validated target for cancer therapy and diagnostics. Herein, we report the inhibition properties of isomeric families of sulfonamidopropyl‐dicarba‐closo‐dodecaboranes group(s) prepared using a new direct five‐step synthesis from the…
Abstract Anisotropic nanoparticles and their dispersions have attracted much attention because of their distinguished characteristics and promising applications. In this study, the novel liquid crystalline nanocomposite ionogel electrolyte materials based on anisotropic nanoparticles of attapulgite (ATP) have been pre…
Compression-induced solidification has been observed in cerium on nanosecond timescales. A series of experiments was conducted in Sandia National Laboratories' Z Facility in which cerium was shock melted and subsequently shocklessly, or ramp, loaded across the melt line inducing solidification. The signature of solidi…
The design and development of an efficacious tumor-specific drug-delivery system is a challenging task. In this study, we have synthesized target-specific small peptide substrates on an octaguanidine sorbitol scaffold, named small molecular targeted drug-delivery conjugate (SMTDDC). The SMTDDC fabrication, with dual t…
Abstract Owing to their high surface area, high concentration of active metal sites, and water stability, zirconium(VI)‐based metal–organic frameworks (Zr‐MOFs) have shown excellent activity in the hydrolysis of organophosphorus nerve agents (OPNs). In this regard, for the first time, two topologically different Zr‐MO…
The transformation behavior and microstructural evolution during continuous cooling within the heat affected zone between the weld beads of a 2.25Cr-1Mo-0.25V all-weld metal and the corresponding 2.25Cr-1Mo-0.25V base metal were investigated by means of dilatometer measurements, optical and scanning electron microscop…
A heat transfer model and a cellular Automation-Finite Element (CAFE) coupling model were established to analyze the solid/liquid (S/L) interface and solidification structure evolution of high purity copper Direct-chill (DC) casting billet under different casting conditions. The simulation and actual experimental resu…
Polymer vesicles with intrinsic molecular permeability have attracted attention as structural components for nano/microreactors in the context of drug delivery and artificial cells. However, the molecular mechanism of the permeability has not yet been elucidated. Herein, we report the relationship between the hydratio…
AIM: Polyamidoamine (PAMAM) dendrimers are attracting interest of the scientists as vehicles for nucleic acid delivery due to their suitable properties. The highly positive surface charged of PAMAM enables an adequate interaction with negatively charged microRNAs. PURPOSE: The purpose of this study is to investigate t…
Non-noble metal and nitrogen codoped carbon catalysts are considered as the alternative options for Pt-based materials for the cathodic oxygen reduction reaction (ORR). Atom transfer radical polymerization (ATRP) has been frequently adopted to synthesize functional polymers. However, the catalysts of ATRP could form a…
The photocatalytic reduction of Cr (VI) is investigated over phosphonate‐based metal–organic frameworks (MOFs) structured as STA‐12(M)(M = Mn, Fe, Co, Ni). The removal of Cr (VI) appears to be faster with STA‐12(Fe) under natural sunlight. The correlation among responses to effective variables as main and interactions…
Abstract A few studies have claimed that Pt single‐atom catalysts (SACs) can catalyze the oxygen reduction reaction (ORR) following a four‐electron pathway (O2+4H++4e−→2H2O). Here, we show that, in the presence of a seemingly negligible amount of Pt nanoparticles, the ORR can mistakenly be thought to occur via a four‐…
Tailoring the properties of porous organic materials, such as resorcinol-formaldehyde gels, for use in various applications has been a central focus for many studies in recent years. In order to achieve effective optimisation for each application, this work aims to assess the impact of the various synthesis parameters…
