In recent years, due to their structural diversity, adjustability, versatility, and excellent electrochemical properties, organic compounds with nitrogen-containing groups (OCNs) have become some of the most promising electrode materials. The acting as active sites include carbon–nitrogen groups, nitrogen–nitrogen nitrogen–oxygen in OCNs, covalent frameworks. molecular structure regulation OCNs...

Creating emotionally engaging mobile applications requires consideration of constantly evolving technology, content richness, usability, and user experience (UX). UX plays an important role in promoting long-term usage. We focused on the emotional aspects design applications. In particular, we adopted concept feelings being (FoB) – also known as existential context design. presented in-depth li...

Abstract Magnetic nanoparticles are used in a wide range of medical applications. However, the accurate steering particles through vascular system is still an open research question. Thus, this paper introduces novel hybrid magnetic array for bifurcation. The consists permanent plus electromagnets and based on Halbach structure. It combines advantages strong field low-cost magnets with adjustab...

Finding a way for mitigating climate change is one of the main challenges our generation. Sorption-enhanced gasification (SEG) process by which syngas as an important intermediate synthesis e.g., dimethyl ether (DME), bio-synthetic natural gas (SNG) and Fischer–Tropsch (FT) products or hydrogen can be produced using biomass feedstock. It can, therefore, contribute to replacement fossil fuels re...

Flat electronic bands with tunable structures offer opportunities for the exploitation and manipulation of exotic interacting quantum states. Here, we present a controllable route to construct easily flat in folded graphene by nano origami-controlled strain engineering, discover correlated states this system. Via tearing folding monolayer at arbitrary step edges scanning tunneling microscope ma...

Revolutionary changes in energy storage technology have put forward higher requirements on next-generation anode materials for lithium-ion battery. Recently, a new class of with complex stoichiometric ratios, high-entropy oxide (HEO), has gradually emerging into sight and embracing the prosperity. The ideal elemental adjustability attractive synergistic effect make HEO promising to break throug...

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...

A multi-wavelength erbium-doped fiber laser (MW-EDFL) with wide tuning range, switching and adjustable wavelength interval is designed tested, which based on a composite filter. The filter consists of tapered microfiber coupler loop (TMCL) nested single mode (SMF)-two (TMF)-SMF (STS) structure, has comb spectrum obvious envelope uniform fluctuation. Our experimental theoretical results show tha...

Abstract This study traces the development of dexterous hand research and proposes a novel antagonistic variable stiffness finger mechanism to improve safety in unpredictable environments, such as unstructured or man-made operational errors through comprehensive consideration cost, accuracy, manufacturing, application. Based on concept mechanical passive compliance, which is widely implemented ...
