For a long time, chemiresistive gas sensors based on metal oxide semiconductors (MOSs) suffer from higher operating temperatures, resulting in energy consumption and instability of the sensors. Generally, MOS-based sensor being able to work at room temperature is considered be outstanding already. Here, highly sensitive NO2 carbon dots-WO3 heterostructure, which can below –6 °C, fabricated. At 18, –1, its detection limits are 200 ppb, 5 ppm, 20 respectively, corresponding response values...

Here, an ultrasensitive chemiresistive gas sensor based on γ-Bi2MoO6-CuO heterostructure with detection limit 5 ppb has been fabricated. It can distinguish asthmatic patients healthy people roughly analyzing exhaled breaths 28 people, suggesting that be used assist physicians diagnosis Pathologically, it...
Abstract Room‐temperature sodium–sulfur batteries are potential candidate for sustainable large‐scale energy storage systems due to their high density and low cost. However, the shuttling effect of high‐order polysulfides (Na 2 S n , 4 < ≤ 8) usually leads rapid capacity fading, while reaction kinetics low‐order 1 4) slow. In this work, microporous‐mesoporous carbon derived from mangosteen peels is reported as cathode materials RT Na–S batteries. The designed micro‐mesoporous structure...

A compact fiber-optic vector rotation sensor in which a short section of polarization-maintaining (PM) fiber stub containing straight Bragg grating (FBG) is spliced to another single mode without any lateral offset proposed and experimentally demonstrated. Due the intrinsic birefringence PM fiber, two well-defined resonances (i.e. orthogonally polarized FBG core modes) with wavelength separation 0.5 nm have been achieved reflection, they exhibit high sensitivity rotation. Both orientation...
Distribution network loss analysis is crucial for the economic operation in residential distribution networks. The increasing level of distributed generation (DG) has considerably improved overall sustainability but raised uncertainty system losses and exacerbated voltage profiles.
