Abstract To overcome the low efficiency of overall water splitting, highly effective and stable catalysts are in urgent need, especially for anode oxygen evolution reaction (OER). In this case, nickel selenides appear as good candidates to catalyze OER other substitutable anodic reactions due their high electronic conductivity easily tunable structure meet optimized adsorption ability. Herein, an interesting phase transition from hexagonal NiSe (H‐NiSe) rhombohedral (R‐NiSe) induced by...
We use ultrafast phase-contrast imaging to directly observethe cone-like terahertz (THz) Cherenkov wave generated by optical rectification of femtosecond laser pulses focused into bulk lithium niobate (LiNbO₃) single crystals. The transverse geometry allows the angle, THz velocity, and pump pulse group velocity be measured. Furthermore, transition-like radiation at air-crystal boundary is observed. effect polarization on generation waves in LiNbO₃ also investigated.

We verified that high-temperature (773 K) H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O vapor can be measured quantitatively with terahertz (THz) spectroscopy in the frequency range of 0.5-0.8 THz. The linear relationships between absorbance peak area and volume mixing ratio (VMR) at three absorption peaks (0.557 THz, 0.658 0.752 THz) match HITRAN-based simulations closely, which indicates HITRAN database used for practical...
Vertically-aligned millimeter-scale multiwall carbon nanotube arrays (CNTAs) grown by catalytic chemical vapour deposition were cut femtosecond laser pulses into thin free-standing sheets of aligned nanotubes. Terahertz (THz) time-domain spectroscopy was used to measure the polarization dependence transmittance CNTA from 0.5-2.2 THz. with thicknesses 40 μm and 150 showed high extinction ratios at 1 THz 25 dB dB, respectively. Furthermore, sheet for parallel nanotubes decreased increasing...
The study of the linear and nonlinear optical properties ZnGeP2 based on density functional theory has been carried out. In order to get a more physical picture in infrared region, terms which are considered as phonon effect were added calculated refractive dispersion curves. phonon-corrected calculation curves show excellent agreement with experimental indexes, gives better comprehension proprieties transparent region. static susceptibility was investigated using approaches sum over states...

Pericarpium citri reticulatae (PCR, also called Chenpi) is an important medical and food resource in China. The medicinal value market price of Chenpi varies greatly among different origins years. Traditional sensory identification methods involve a great deal subjectivity, while chemical are cumbersome have low repeatability. In recent years, the classification method using electromagnetic spectrum combined with machine learning has become new means identifying PCR, but problems such as...
Traditional differential expression genes (DEGs) identification models have limitations in small sample size datasets because they require meeting distribution assumptions, otherwise resulting high false positive/negative rates due to variation. In contrast, tabular data model based on deep learning (DL) frameworks do not need consider the types and However, applying DL RNA-Seq is still a challenge lack of proper labeling compared number genes. Data augmentation (DA) extracts features using...
