An efficient detection method for camel milk quality based on dielectric spectroscopy technology.

To address the long-standing dual challenges in the camel milk industry, namely, the difficulty in identifying adulteration and the severe lag in nutritional component detection, this study analyzed the variation patterns of the dielectric constant (ε') and dielectric loss factor (ε") of camel milk fat, protein, and lactose. Based on the dielectric spectrum, detection models were constructed using partial least squares (PLS), convolutional neural network (CNN), long short-term memory network (LSTM), CNN-LSTM, and an optimized CNN-LSTM fused with the crested porcupine optimizer (CPO) and squeeze-and-excitation network (CPO-CNN-LSTM-SEN) for camel milk quality detection. The results indicate that across the 0.

Constructing Synergistic Interactions Between Multi-Hydroxyl Molecules and Perovskite to Alleviate Mechanical-Thermal Mismatch for Achieving High-Performance Flexible Solar Cells.

Due to the presence of residual tensile strain, as well as the inherent brittleness and film quality of the perovskite, flexible perovskite solar cells (f-PSCs) face ongoing challenges in stability. To address these issues, this study introduces a multi-hydroxyl regulated stress management strategy for f-PSCs. Three hydroxyl-substituted phenylacetic acids (p-hydroxyphenylacetic acid, 3,4-dihydroxyphenylacetic acid, and 2-(3,4,5-trihydroxyphenyl)acetic acid) are incorporated into the perovskite films to investigate the significance of their interaction modes with perovskite in regulating f-PSC performance.

Fabrication of lignin-MOF derived spherical carbon supported NiCo-bimetallic catalysts for selective hydrogenolysis lignin derived ether.

The conversion of abundant lignin was of great significance for the utilization of biomass resources. In this study, lignin sulfonate (LS) was selected as a carbon-based support, which was successfully introduced into the NiCo-MOF structure. A series of lignin and MOF hybrid catalysts (NiCo-MOF-LS) with varying metal ratios of Ni and Co were synthesized via the hydrothermal method.

Bimetallic nickel‑cobalt sulfide derived from lignin-MOFs hybrid as a high-efficiency heterogeneous catalyst for hydrogenolysis of lignin dimers.

Lignin represents a significant source of aromatic hydrocarbons in the natural world. The production of high-value chemicals from lignin has the great potential to effectively address the issue of fossil energy scarcity. In this study, complex sulfides of nickel‑cobalt bimetallic catalysts were prepared via hydrothermal synthesis and subsequently employed in the catalytic hydrogenolysis of CO bonds present in lignin.

Exercise alters molecular rhythms in the central nervous system that negatively correlate with depression-like behavior.

Major depressive disorder (MDD) ranks among the top 10 leading causes of death. However, exercise is known to improve depressive symptoms but the mechanism responsible is still unknown. To date, numerous studies have shown that molecular rhythms and exercise are associated with MDD.
