HO inducing dissolved oxygen activation and electron donation of pollutants over Fe-ZnS quantum dots through surface electron-poor/rich microregion construction for water treatment.

In common advanced oxidation processes, excess reagents and energy are often added to the reaction system to maintain the continuity of the reaction. These additions result in a large waste of resources and energy, which has become a bottleneck in the development of water treatment technology. In this study, we propose a new strategy to solve this problem based on a novel dual-reaction-center (DRC) Fe-ZnS quantum dots (Fe-ZnS QDs) catalyst that forms a non-equilibrium surface with an electron-polarized distribution.

TRIM44 mediated p62 deubiquitination enhances DNA damage repair by increasing nuclear FLNA and 53BP1 expression.

Cancer cells show increases in protein degradation pathways, including autophagy, during progression to meet the increased protein degradation demand and support cell survival. On the other hand, reduced autophagy activity during aging is associated with a reduced DNA damage response and increased genomic instability. Therefore, it is a puzzling how DNA repair can be increased in cancer cells that are resistant to chemotherapies or during progression when autophagy activity is intact or increased.

Variations in the light absorption coefficients of phytoplankton, non-algal particles and dissolved organic matter in reservoirs across China.

Reservoirs were critical sources of drinking water for many large cities around the world, but progress in the development of large-scale monitoring protocols to obtain timely information about water quality had been hampered by the complex nature of inland waters and the various optical conditions exhibited by these aquatic ecosystems. In this study, we systematically investigated the absorption coefficient of different optically-active constituents (OACs) in 120 reservoirs of different trophic states across five eco-regions in China. The relationships were found between phytoplankton absorption coefficient at 675 nm (a (675)) and Chlorophyll a (Chla) concentration in different regions (R:0.

Electromagnetic Wave-Absorbing and Bending Properties of Three-Dimensional Honeycomb Woven Composites.

To avoid the delamination of the traditional three-dimensional (3-D) honeycomb electromagnetic (EM) absorbing composites and improving the defects of low mechanical properties, the 3-D honeycomb woven fabrics were woven on the ordinary loom by practical design. The fabrication of 3-D honeycomb woven EM absorbing composites was based on carbon black/carbonyl iron powder/basalt fiber/carbon fiber/epoxy resin (CB/CIP/BF/CF/EP) by the vacuum-assisted resin transfer molding (VARTM) process. A CB/CIP composite absorbent study showed that CB/CIP composite absorbent belongs to a magnetic loss type absorbent.

MD-UNET: Multi-input dilated U-shape neural network for segmentation of bladder cancer.

Accurate segmentation of the tumour area is crucial for the treatment and prognosis of patients with bladder cancer. However, the complex information from the MRI image poses an important challenge for us to accurately segment the lesion, for example, the high distinction among people, size of bladder variation and noise interference. Based on the above issues, we propose an MD-Unet network structure, which uses multi-scale images as the input of the network, and combines max-pooling with dilated convolution to increase the receptive field of the convolutional network.

[Fe-Ti Co-Doped Alumina-Induced Surface Dual Reaction Center for Catalytic Ozonation to Remove Pollutants from Water].

Multiphase catalytic ozone oxidation technology has received wide attention for its effectiveness in removing organic pollutants from water. However, the existence of a rate-limiting step in the metal oxide-catalyzed ozonation process based on single-site redox, which inhibits the activity, greatly limits the practical application of the multiphase catalytic ozonation technology. To solve this bottleneck problem, lattice doping of metal oxide -AlO substrates with transition metal species Fe and Ti was used to prepare novel dual reaction center catalysts (FT-A-1 DRCs).
