Large contact forces on granules could give rise to undesirable attrition. In a new device, referred as the Particle Shear and Impact tester, are subjected repeated sequential impact shearing, latter effected by two counter-rotating rollers with differential angular speeds an adjustable gap between rollers. This enables force distribution be varied in order apply representative forces, experien...

we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

We present a theoretical analysis of three-dimensional (3D) matter-wave solitons and their stability properties in coupled atomic and molecular Bose-Einstein condensates (BECs). The soliton solutions to the meanfield equations are obtained in an approximate analytical form by means of a variational approach. We investigate soliton stability within the parameter space described by the atom-molec...

Assembly and directed orientation of anisotropic particles with an external ac electric field in a range from 1 kHz to 2 MHz were studied for asymmetric composite dumbbells incorporating a silica, titania, or titania/silica (titania:silica = 75:25 vol %) sphere. The asymmetric composite dumbbells, which were composed of a polymethylmethacrylate (PMMA)-coated sphere (core-shell part) and a polys...

We derive a general lower bound on distributions of entropy production in interacting active matter systems. The is tight the limit that interparticle correlations are small and short-ranged, which we explore four canonical models. In all models studied, weak where collective fluctuations result long-ranged correlations, subsequently links locations phase transitions to enhanced fluctuations. d...

Lately intense research interests have been focused on the electronic conductivity properties of transition-metal nanoparticles (e.g., Au, Pd, and Ag) that are passivated by an organic monolayer (i.e., the so-called monolayer-protected nanoparticles).1 With such a core-shell composite nanostructure, the resulting conductivity can be tailored by the combined effects of the conductive inorganic c...

Pulmonary drug delivery can have several advantages over other administration routes, in particular when using dry powder formulations. Such inhalation formulations generally include natural and bio-inspired excipients, which, among purposes, are used to improve dosing reproducibility aerosolization performance. Amino acids enhance dispersibility provide protection against moisture uptake. Suga...

Abstract We investigate the potential energy curves of rare-gas dimers with various ranges and strengths of interparticle interactions (nuclear-electron, electron-electron, and nuclear-nuclear interactions). Our investigation is based on the highly accurate coupled-cluster theory associated with those interparticle interactions. For comparison, the performance of the corresponding Hartree-Fock ...

By using electron beam lithography, we fabricated pairs of gold nanoparticles with varying interparticle separation. Double-beam femtosecond transient absorption spectroscopy was used to determine the coherent lattice oscillation frequency as a function of the interparticle separation in the presence of the plasmon field excited by the monitoring probe light. We found that the fractional shift ...

Choosing a career within the military has many positive and negative factors associated with it. For instance, many recruits join as young adults when they are beginning to shape their own values, beliefs and attitudes about their self, world and others. The armed forces (AF) culture socialises these young adults, leading them to adopt military values and ideals as their own which they will pro...
