A low-cost biochar adsorbent (BA) was synthesized via one-step co-pyrolysis of oily sludge and wheat straw for the treatment of oilfield produced water. The effects of co-pyrolysis and adsorption conditions on removal efficiency were studied, and the adsorption conditions were further optimized usin...

The axial resolution of optical coherence tomography (OCT) is determined by the spectral shape and bandwidth of the detected light, which are limited by the gaps in the wavelength range of illumination, transmission, and detection. In this paper, we demonstrate that the axial resolution deteriorated...

A sensitive method was developed for detecting diazepam residues in aquatic products using magnetic dispersive solid-phase extraction (MDSPE) coupled with ultra-performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS). Samples extracted with 1% ammonia–acetonitrile were purified using...

The mucosal microanatomy of the large intestine is characterized by the presence of crypts of Lieberk&#x00FC;hn, which is associated predominantly with goblet cells. Such cellular-level intestinal microstructures undergo morphological changes during the progression of bowel diseases, such as col...

Due to the short duration and complexity of ship shock responses, the shock response spectrum(SRS) is commonly used as a tool for analyzing these responses. To address the conflict between calculation speed and accuracy inherent in traditional SRS solving methods, this paper proposed a deep learning...

Here, we experimentally demonstrate a faithful single-photon qubits transmission using error-rejecting coding, resorting to neither ancillary photons nor entangled photon resources. Using unbalanced polarization interferometer, the polarization qubits are transferred into the state on time-bin degre...

Abstract Graphitic carbon nitride (g‐C3N4), a prominent metal‐free semiconductor photocatalyst, faces limitations due to its high exciton binding energy. While significant efforts have been focused on optimizing charge‐carrier processes, the interplay of exciton and free carrier in this system have...

Abstract Developing a new strategy to address water vapor poisoning is crucial for catalysts in real‐working conditions. Except for the traditional thinking of resistance enhancement, a reverse idea is proposed herein of utilizing the inevitable H2O, converting it to active ·OH to enhance the overal...

Summary: IRE1α and its downstream XBP1 signal is the most conserved unfolded protein response pathway that cells utilize to combat endoplasmic reticulum stress, also known to be utilized by tumor cells to adapt to harsh environment, leading to tumor progression. Several inhibitors against IRE1α have...

Optical coherence tomography angiography (OCTA) is a powerful tool for non-invasive, label-free, three-dimensional visualization of blood vessels down to the capillary level in vivo. However, its widespread usage is hindered by the trade-off between transverse sampling rate and signal-to-noise ratio...
