A straight-line type Sagnac optic fiber acoustic sensing system is proposed in this paper. The Sagnac interference fiber loop is replaced by a straight-line fiber and a 1×2 coupler to enhance the environmental adaptability, and the length of Sagnac interference fiber loop is shortened close to...

The face-centered cubic CrCoNi medium-entropy alloy (MEA) as one of the derivatives of the CoCrFeMnNi high-entropy alloy has drawn much attention due to its remarkable mechanical properties. However, tribological behaviors of the CrCoNi MEA have been rarely reported. Herein, using large-scale...

Anammox is one of the most promising denitrification processes, but the slow growth rate of AnAOB limits its application. This paper focused on the start-up time, influent fluctuation, specific activity, and enzyme activity of AnAOB under the strategy of negative pressure coupled with direct...

The recent advances in bioanalytical technology have accelerated the analysis of complex protein glycosylation, which is beneficial to understanding glycosylation in drug discovery and disease diagnosis. Due to its biological uniqueness in the course of disease occurrence and development,...

Solar water splitting is an eco-friendly technology to produce clean energy, but the water oxidation half reaction hinders the overall water splitting due to four electron transfer processes. Z-Scheme photocatalytic system could effectively promote the separation of photogenerated carriers and...

V o (oxygen vacancy)-Ce-CuO nanosheet catalysts were studied for degrading niflumic acid (NFA) by the heterogeneous Fenton-like process (HFLP). Synergetic effects of triple reaction centers with electron-rich V o and single Ce atom have demonstrated for generating hydroxyl radicals (•OH) by H...

Cyanide (CN - ) is one of the strongest and fastest-acting toxic substances, and its excessive presence will cause great harm to the environment, food and human health. Although several fluorescent probes that recognize CN - have been extensively reported, developing the fluorescent probe with...

Hollow anammox granules have been concerned in the field of anammox granular sludge technology. So far, little information is available about the effect of shear stress on hollow anammox granules. The evolution of hollow granular sludge at three shear stresses (τ = 0.014, 0.041, and 0.075 Pa)...

Despite heavy research, the efficiencies of blue perovskite light-emitting diodes (LEDs) lag behind those of their green and red cousins. One of the most critical problems is the lack of technology to obtain both high blue emission and spectral stability of perovskite in thin films. Herein, we...

We examine the effect of insider share pledges on corporate fraud. We find a positive, causal relation between share pledges by controlling shareholders and detected corporate fraud. Firms whose controlling shareholders pledge have longer fraud detection cycles and receive lighter punishments....
