How to improve the stability and activity of metal-organic frameworks is an attractive but challenging task in energy conversion and pollutant degradation of metal-organic framework materials. In this paper, a facile method is developed by fabricating titanium dioxide nanoparticles (TiO NPs) layer on 2D copper tetracarboxylphenyl-metalloporphyrin metal-organic frameworks with zinc ions as the linkers (ZnTCuMT-X, "Zn" represented zinc ions as the linkers, the first "T" represented tetracarboxylphenyl-metalloporphyrin (TCPP), "Cu" represented the Cu coordinated into the porphyrin macrocycle, "M" represented metal-organic frameworks, the second "T" represented TiO NPs layer, and "X" represented the added volume of n-tetrabutyl titanate (X = 100, 200, 300 or 400)). It is found that the optimized ZnTCuMT-200 showed greatly and stably enhanced H generation, which is ≈28.

Climate change, the overconsumption of fossil fuels, and rapid population and economic growth have collectively driven a growing emphasis on environmental sustainability and the need for effective resource management. Chemicals or materials not currently regulated are known as contaminants of emergent concern (CECs). Nevertheless, wastewater is thought to be its main source, and worries about its probable presence in the environment are growing due to its potential damage to human and environmental health.

Article Synopsis
- Hyperspectral imaging is increasingly using deep learning techniques instead of traditional methods for processing, but many researchers don't adequately analyze how spectral and spatial information interact.
- The paper assesses how different combinations of spatial (texture) and spectral (light wavelength) features affect deep learning models for image segmentation, focusing on performance, energy usage, and speed.
- Results indicate that integrating spatial data with spectral information enhances segmentation accuracy, but not all spectral wavelengths are needed for optimal efficiency, and adapting existing RGB image models for hyperspectral tasks needs further innovation.

Coordinating the droplet capture, transport, and shedding processes during fog collection to achieve efficient fog collection is a major challenge. In this study, a copper mesh with different wettability was prepared by chemical etching and thiol modification. The Cu(OH) needle structure on the surface of the samples was characterized by FE-SEM and EDS tests, and the surface of the samples was chemically analyzed by infrared and XPS analyses.

Copper plays an important role in the regulation of PD-L1, suggesting that reducing copper levels within tumors may enhance anti-cancer immunotherapy. Tumor microenvironment responsive copper nanodeprivator (TMECN) was developed for enhancing immunotherapy of tumor via the cross-link of mercaptopolyglycol bipyridine and dimercaptosuccinic acid modifying FePt nanoalloy using the disulfide bond. Upon entering tumor cells, the disulfide bond in TMECN is cleaved by the overexpressed glutathione, exposing abundance of sulfhydryl groups.
