Nanomaterials Optical elements can generate circularly polarized luminescence (CPL), but sources that directly emit CPL are desirable for many applications. Kim et al. synthesized formamidinium lead bromide nanocrystals (NCs) with mixtures of longer achiral ligands and shorter chiral ( R )-2-octylamine. Lower fraction…
Abstract The ab initio molecular dynamics simulations were adopted to study the atomic structures of Co92−xBxTa8 (x = 30, 32.5, 35, 37.5, at%) glassy alloys. The results showed that the local packing of B‐centered clusters was more efficient than that of Co‐ and Ta‐centered clusters. It was also found that B‐centered…
Abstract This work presents the application of a cobalt and manganese mixed oxides‐based catalyst with spinel structure to the decomposition of the storable green monopropellant H2O2 90 wt%. The 5.4 % Co0.5Mn2.5O4/Al2O3 catalyst was tested in a series of continuous and pulsed 2 N thruster firings, yielding a fast and…
Perfect absorbers have been extensively investigated due to their significant value in solar cell, photodetection, and stealth technologies. Various subwavelength structures have been proposed to improve the absorption performances, such as high absorptance, broad band, and wide absorption angle. However, excellent pe…
Abstract The interaction mechanism of B and Ti in liquid Gd metal was theoretically analyzed, and the occurrence state transformation and removal of Ti impurity were experimentally analyzed in this study. The research results indicated that the B additive reacted with the Ti impurity in liquid Gd metal to form the hig…
An aluminum nitride (AlN) piezoelectric resonant infrared (IR) detector based on a Lame-wave resonator (LWR) and plasmon apertures was designed for dual-band sensing, and was investigated by using the finite element method (FEM) and finite difference time domain (FDTD) simulations. A plasmon structure with the apertur…
Abstract On‐surface synthesis is emerging as a highly rational bottom‐up methodology for the synthesis of molecular structures that are unattainable or complex to obtain by wet chemistry. Here, oligomers of meta‐polyaniline, a known ferromagnetic polymer, were synthesized from para‐aminophenol building‐blocks via an u…
Abstract The phase diagrams of polystyrene (PS)‐poly(vinyl methyl ether) (PVME) system obtained via optical interferometry in the study of polymer interdiffusion are presented. The influence of molecular weight of the PS on the position of the binodal curve dome and the critical point is shown. Paired interaction para…
High Resolution Image Download MS PowerPoint Slide Characterizing nanocages in macromolecules is one of the keys to understanding various biological activities and further utilizing nanocages for novel materials synthesis. However, fast and straightforward detection of the nanocage size remains challenging. Here, we p…
PURPOSE: Publicly available data provision is an essential part of open science. However, open data can conflict with data privacy and data protection regulations. Head scans are particularly vulnerable because the subject's face can be reconstructed from the acquired images. Although defacing can impede subject ident…
Studies of interactions between polymers and oxide surfaces have paid attention to the numerous technological and industrial applications as well as the importance of a fundamental standpoint. Several reviews have been reported through theoretical and experimental descriptions [ 1-10 ].
A method and device for dispersing molten metal into fine particulate spray, the method comprises applying an electric current through the molten metal and simultaneously applying a magnetic field to the molten metal in a plane perpendicular to the electric current, whereby the molten metal is caused to form into drop…
Minimization or elimination of cogging torque is a significant issue in permanent magnet (PM) motor design process. There are some design techniques to reduce or eliminate this unwanted torque components in PM motors. This paper focuses on two different design techniques, varying magnet pole-arc and step-skew, to redu…
In this study, plasma discharge in a liquid at intensive ultrasonic field above the cavitation threshold has been proven to be of great interest for initiation of various physical and chemical processes. In such surcharge, nanoparticles of tungsten oxide with controlled size and shape and narrow particle size distribu…
Diante do atual cenário de crescente desenvolvimento de novos produtos, o presente estudo analisou a durabilidade de compósitos reforçados com fibras de banana e de batata-doce, tendo o PVA como agente ligante, em formulações com híbridos e fibras únicas. No trabalho, foram conformadas três diferentes formulações, sen…
Abstract The present study investigated the effect of surface roughness on plasma assisted nitriding (PAN) process kinetics of Ni-base alloys. Two model alloys, namely Ni-10Cr and Ni-14Cr-4Al (wt.%) and commercial Rene 80, were examined. To elucidate the effect of surface roughness on nitriding kinetics, three methods…
This work is concerned with the effect of non-Maxwellian electrons and obliqueness of magnetic field on magnetized plasma sheath characteristics, in which plasma interacts with tungsten (W) and molybdenum (Mo) surfaces via non-neutral plasma sheath using two fluids model. It is assumed that the singly charged positive…
Com o intuito de favorecer e acelerar o processo de bioxidação de resíduos orgânicos para obtenção de um produto final de melhor qualidade, estabilizado e higienizado, e em um menor intervalo de tempo, vários biorremediadores para inoculação a base de microrganismos efetivos estão disponíveis no mercado. A eficiência…
Mobilization of nickel in an acidified, non-calcareous, sandy aquifer was studied through integrated field, laboratory and modeling studies. Apparently, the majority of the solid phase bound nickel is associated with silicate minerals. This nickel pool is probably released to the aqueous phase by dissolution/weatherin…
