Binary transition metal nitride with a graphene-like structure and strong magnetic properties is rare. Based on the first-principles calculations, we design two kinds of $M{\mathrm{N}}_{4}$ ($M$ = metal) monolayers, which are nitrides planar structure, made up units aligned in rhombic square patterns. The structural lattices have robust stability good compatibility different atoms, underlying m...

In-plane anisotropy (IPA) due to asymmetry in lattice structures provides an additional parameter for the precise tuning of characteristic polarization-dependent properties two-dimensional (2D) materials, but narrow range within which such method can modulate hinders significant development related devices. Herein we present a novel periodic phase engineering strategy that remarkably enhance in...

In this article, the working mechanism of a wideband absorber designed with an adjustable and highly selective notch band is studied, in which narrow independently controlled by lower lossless layer absorber, whereas upper lossy loaded lumped resistors realizes absorption. We present two instances geometrically electrically bands, respectively. Without decreasing absorption performance, positio...

Lead halide perovskites have received considerable attention from researchers over the past several years due to their superior optical and optoelectronic properties, because of which they can be a versatile platform for fundamental science research applications. Patterned structures based on lead much more novel properties compared with commonly seen bulk-, micro-, nano-crystals, such as impro...

The present research carried out to study the relationship of market orientation and innovation and their effect on entrepreneurship and value creation for customers. To do so, as the sample was unlimited, 241 active companies in agriculture and food industry were selected as the samples by random sampling method. Via standard questionnaire, we gathered data on managers and senior experts' opin...

Ultra-fast high-voltage switches (UFHVSs) are a core component of time-of-flight mass spectrometers for realizing high accuracy ion acceleration, deceleration, and temporal focusing. The desirable features performance UFHVSs include large range adjustability pulse width, maximum output amplitude, minute rising falling times. Besides the simplicity driver circuit, total cost whole device is also...

The flat-top magnetic field (FTMF) can meet scientific experimental requirements for higher intensity, longer pulse width, and lower ripple in physics, chemistry, biology, other fields. This paper proposes an FTMF system powered by the multiple-capacitor power supply (MCPS). MCPS consists of several capacitor banks with customizable capacitance given voltage. These discharge sequentially based ...

Anthropometry is critical for product and workplace design. Highly prevalent, office work associated with sedentarism physical discomfort due to prolonged sitting. Dynamic seating (alternating across sitting, perching, standing) has been suggested as an alternative overcome those problems. The current study tested a large sample of anthropometric data mismatch levels against national internatio...
