Diabetes mellitus is a chronic metabolic disease, and its progression leads to serious complications. Although various novel therapeutic approaches for diabetes mellitus have developed in the last three decades, its prevalence has been rising more rapidly worldwide. Silk-related materials have been used as anti-diabet…
This study aims to determine the ballistic characteristics of the two steel plates with different hardness levels and mix in the form of layered in non-permanent constructions. Ballistic testing by caliber 5.56 × 45 mm deformed full metal jacket on a sample plate with each a thickness of 6 mm at a distance of 15 m wit…
Abstract Atomic dispersion of dopants and control over their defect chemistry are central goals in the development of oxide nanoparticles for functional materials with dedicated electronic, optical or magnetic properties. We produced highly dispersed oxide nanocubes with atomic distribution of cobalt ions in substitut…
This study describes the synthesis, structure, and photophysical properties of a new luminescent polyaromatic boronic acid scaffold, diazaboryl-naphthyl-ketones (DNKs). These stable compounds display extremely bright fluorescence, aggregation-induced emission, positive solvatochromism, and solid-state fluorescence. DF…
Gated trilayer graphene exhibits an energy gap in its most stable ABC stacking. Here we show that when the stacking order changes from ABC to CBA, three gapless states appear in each valley. The states are topologically protected, and their number is related to the change in the valley Chern number across the stacking…
With the rapid advancement of medical technology, it is crucial that a considerable body of biomaterials are taken into consideration and tested for the purpose of bone implant fabrication. Over the last decades degradable metallic materials have attracted increasing interest in the field of hard tissue engineering du…
In many liquid-phase synthesis methods developed to produce nanomaterials, the key parameters governing the selective synthesis of solids and compounds are clearly identified, for example, heat treatment profile, precursors solubility, pH, and so on. Most of these well-understood approaches rely on relatively low temp…
Nanofibrous materials produced by electrospinning processes have potential advantages in tissue engineering because of their biocompatibility, biodegradability, biomimetic architecture, and excellent mechanical properties. The aim of the current work is to study the influence of the electron beam on the poly L-lactide…
Two-dimensional (2D) materials have shown promise in various optical and electrical applications. Among these materials, semiconducting transition metal dichalcogenides (TMDs) have been heavily studied recently for their photodetection and thermoelectric properties. The recent progress in fabrication, defect engineeri…
The complex phase diagram of manganites with simultaneously active spin, charge, orbital, and lattice degrees of freedom continues providing surprises. In a recent groundbreaking experiment, membranes of the perovskite manganite ${\mathrm{La}}_{0.7}{\mathrm{Ca}}_{0.3}{\mathrm{MnO}}_{3}$ (LCMO) deposited on a flexible…
Materials with random microstructure are characterized by additional thermodynamic parameters, entropy and temperature of microstructure. It has been argued that there is one more law of thermodynamics: entropy of microstructure decays in isolated systems. In this paper, we check this assertion experimentally for the…
We have developed the magnetic probe with a diamond quantum sensor and electromagnetic coils to detect sentinel lymph nodes (SLNs), as the medical application of diamond quantum sensing. The probe magnetizes magnetic nanoparticles (MNPs) accumulated in SLNs and detect the magnetic fields of magnetized MNPs. In this st…
Abstract Grain boundary (GB) migration and Zener pinning, i.e. retardment of migrating GBs by second-phase particles, in a nanocrystalline Cu–Ag alloy have been investigated via molecular dynamics simulation. Among 86 GBs of different rotation axes and misorientation angles, about half of the GBs either did not move f…
Abstract We proposed and demonstrated a reconfigurable water-based metasurface to achieve continuously dynamic control of electromagnetic (EM) reflection within a wide frequency band. The proposed metasurface is an array of an anisotropic unit cell consisting of two metallic layers separated by a dielectric layer. The…
The observation of single molecule events using surface-enhanced Raman scattering (SERS) is a well-established phenomenon. These events are characterized by strong fluctuations in SERS intensities. High-speed SERS intensity fluctuations (in the microsecond time scale) have been reported for experiments involving singl…
Abstract Oxidative polymerization of bis(2-methoxyphenyl) disulfide using a VO(acac)2-strong acid catalyst with O2 or DDQ as an oxidant gave poly(2-methoxy-1,4-phenylenesulfide), which was linear with a molecular weight of Mw = 6.0 × 103, and yet totally amorphous in contrast to poly(1,4-phenylene sulfide) (PPS). The…
Abstract Reaction of 1,2‐di(tetrazol‐2‐yl)ethane (ebtz) with Fe(BF 4 ) 2 ⋅6 H 2 O in different nitriles yields one‐dimensional coordination polymers [Fe(ebtz) 2 (RCN) 2 ](BF 4 ) 2 ⋅ n RCN ( n= 2 for R=CH 3 ( 1 ) and n= 0 for R=C 2 H 5 ( 2 ) C 3 H 7 ( 3 ), C 3 H 5 ( 4 ), CH 2 Cl ( 5 )) exhibiting spin crossover (SCO).…
A new type of diffractive lens based on hybridized Fabry-Perot (FP) cavities with high-NA and achromatic features for arbitrary dual-wavelengths is theoretically proposed and demonstrated. We utilize the subwavelength-scale metal-insulator-metal nanocavity to form a Fresnel zone plate (MIM-FZP) that benefits from both…
Abstract Lattice dynamic properties of the tetragonal modification of ZnP 2 and CdP 2 crystals (space group P4 1 2 1 2, no 92) are calculated within the density functional theory. Theoretical results are shown to compare favorably with available Raman scattering and infrared reflection/transmission experimental data,…
The spinning triangle is an important area in the spinning process, and the shape of the spinning triangle influences the yarn qualities. This paper aims to theoretically study the effects of the spinning parameters on the shape of the spinning triangle. In this paper, a model of the spinning triangle considering forc…
