Tanshinol, an active ingredient extracted from the Salvia miltiorrhiza herb, is widely used in Chinese medicine or health supplements. Accurately and rapidly quantifying of tanshinol under near-neutral or neutral conditions is of great significance but still a significant challenge. Herein, a novel electrochemical sensor based on bimetallic FeCo phosphides (FeCoP) was developed for rapid and sensitive detection of tanshinol in near-neutral environments.

This study optimizes the CuO/GaO heterojunction diodes (HJDs) by tailoring the structural parameters of CuO layers. The hole concentration in the sputtered CuO was precisely controlled by adjusting the Ar/O gas ratio. Experimental investigations and TCAD simulations were employed to systematically evaluate the impact of the CuO layer dimension and hole concentration on the electrical performance of HJDs.

Application of an anodic potential resulted in a blue-shift of the surface plasmon resonance and an incremental increase in its extinction coefficient. Conversely, upon application of a cathodic potential, the surface plasmon band red-shifted and reduced in intensity.

ATLAS measured the centrality dependence of the dijet yield using 165 nb^{-1} of p+Pb data collected at sqrt[s_{NN}]=8.16 TeV in 2016. The event centrality, which reflects the p+Pb impact parameter, is characterized by the total transverse energy registered in the Pb-going side of the forward calorimeter.

Transition metal N-doped carbon catalysts offer a promising alternative to noble metal catalysts, with metal-organic framework (MOF)-derived carbon material catalysts being particularly noteworthy. Here, we synthesized MP-Z-C carbon catalysts by combining two-dimensional (2D) metal porphyrin-based MOFs (MPMFs, x = Fe, Co, Ni, Mn) and three-dimensional zeolitic imidazole framework-8 (ZIF-8) through electrostatic interaction, followed by carbonization.

The structural evolution of black arsenic-phosphorous (b-AsP) alloys with varying arsenic concentrations was investigated under hydrostatic pressure usingRaman spectroscopy. High-pressure experiments were conducted using a diamond anvil cell, which revealed pressure-induced shifts in vibrational modes associated with P-P bonds (,,B2g), As-As bonds (,,B2g), and As-P bonds in b-AsPalloys. Two distinct pressure regimes were observed.

Based on the phase composition, the formation process can be distinctly separated into four zones: Educt, Intermediary, Formation, and Decomposition zone. It is found that instead of Li GeS -Li PS binary crystallization process, diversified intermediate phases, including GeS in different space groups, multiphasic lithium phosphosulfides (Li P S ), and cubic Li Ge PS phase, are involved additionally during the formation and decomposition of Li GeP S .

Searching for functional square lattices in layered superconductor systems offers an explicit clue to modify the electron behavior and find exotic properties. The trigonal SnAs structural units in SnAs-based systems are relatively conformable to distortion, which provides the possibility to achieve structurally topological transformation and higher superconducting transition temperatures. In the present work, the functional As square lattice was realized and activated in Li Sn As and NaSnAs through a topotactic structural transformation of trigonal SnAs to square SnAs under pressure, resulting in a record-high T among all synthesized SnAs-based compounds.

Although mid-infrared photodetectors and mode-locked or Q-switched pulse lasers based on b-AsP (mostly b-AsP) are investigated, the potential of this family of materials for near-infrared photonic and optoelectronic applications at telecommunication bands is not fully explored. Here, we have verified a multifunctional fiber device based on b-AsP nanosheets for highly responsive photodetection and dual-wavelength ultrafast pulse generation at around 1550 nm.

Methods: A multicenter tandem trial was conducted in 11 centers. Seven hundred thirty-three asymptomatic participants were randomized to receive segmental tandem screening colonoscopy with a 9-minute withdrawal, followed by a 6-minute withdrawal (9-minute-first group, 9MF, n = 366) or vice versa (6-minute-first group, 6MF, n = 367).
Black arsenic phosphorus (b-AsP) is expected to be one of the primary materials for future photonic devices. However, the -factor is randomly estimated and applied in photonic devices in current studies, rather than systematically analyzing it for a comprehensive understanding. Herein, AsP switches from a direct band gap semiconductor to an indirect band gap one at = 0.

The objective of this work was to investigate the effect of magnetic resonance cholangiopancreatography (MRCP) based on super-paramagnetic iron oxide nanoparticles (SPIONs) on the recurrence diagnosis of periampullary diverticulum (PAD) and bile duct stone (BDS), so as to provide a scientific research basis for the recidivation factors of bile duct stones in clinic. Patients with PAD diagnosed in hospital from July 2019 to March 2021 (who had undergone endoscopic gallstone surgery) were selected for study in this work. They were rolled into two groups, the parapapillary group (123 cases) and the cholangiopancreatic duct directly opening in the diverticulum group (97 cases), according to the clinical classification.
