Assessing the performance and interpretability of the CNN-LSTM-Attention model for daily streamflow forecasting in typical basins of the eastern Qinghai-Tibet Plateau.

Hydrological forecasting is of great significance to regional water resources management and reservoir operation. Climate change has increased the complexity and difficulty of hydrological forecasting. In this study, a hybrid explainable streamflow forecasting model based on CNN-LSTM-Attention was established for five typical river source regions in the eastern Qinghai-Tibet Plateau (EQTP).

Restoring small water bodies to improve lake and river water quality in China.

Climate change, population growth, and agricultural intensification are increasing nitrogen (N) inputs, while driving the loss of inland water bodies that filter excess N. However, the interplay between N inputs and water body dynamics, and its implications for water quality remain poorly understood. Analyzing data from 1995 to 2015 across China, here, we find a 71% reduction in the area of small (<10 m) water bodies (SWB), primarily in high-N-input agricultural regions.

A filter inspired by deep-sea glass sponges for oil cleanup under turbulent flow.

Oil spill disasters lead to widespread and long-lasting social, economical, environmental and ecological impacts. Technical challenges remain for conventional static adsorption due to hydrodynamic instability under complex water-flow conditions, which results in low oil-capture efficiency, time delay and oil escape. To address this issue, we design a vortex-anchored filter inspired by the anatomy of deep-sea glass sponges (E.

Efficient and Stable Extraction of Nano-Sized Plastic Particles Enabled by Bio-inspired Magnetic "Robots" in Water.

In this research, a rationally-designed strategy was employed to address the crucial issue of removing nano-plastics (NPs) from aquatic environments, which was based on fabricating sea urchin-like structures of FeO magnetic robots (MagRobots). Through imitating the sea urchin's telescopic tube foot movement and predation mechanism, the unique structures of the MagRobots were designed to adapt to the size and surface interactions of NPs, leading to a high efficiency of NPs removal (99%), as evidenced by the superior performance of 594.3 mg/g for the removal of polystyrene (PS) nanoparticles from water, with 3300% increase over magnetic FeO without structural design.

Tantalum-stabilized ruthenium oxide electrocatalysts for industrial water electrolysis.

The iridium oxide (IrO) catalyst for the oxygen evolution reaction used industrially (in proton exchange membrane water electrolyzers) is scarce and costly. Although ruthenium oxide (RuO) is a promising alternative, its poor stability has hindered practical application. We used well-defined extended surface models to identify that RuO undergoes structure-dependent corrosion that causes Ru dissolution.

Active Microrobots for Dual Removal of Biofilms via Chemical and Physical Mechanisms.

Bacterial biofilms are complex multicellular communities that adhere firmly to solid surfaces. They are widely recognized as major threats to human health, contributing to issues such as persistent infections on medical implants and severe contamination in drinking water systems. As a potential treatment for biofilms, this work proposes two strategies: (i) light-driven ZnFeO (ZFO)/Pt microrobots for photodegradation of biofilms and (ii) magnetically driven ZFO microrobots for mechanical removal of biofilms from surfaces.

Unlike conventional fluorophores suffering from aggregation-caused quenching, AIEgens exhibit enhanced luminescence when aggregated, enabling superior imaging performance.

Self-Assembly and Drug Encapsulation Properties of Biocompatible Amphiphilic Diblock Copolymers.

To prepare amphiphilic diblock copolymers (MP), a controlled radical polymerization approach was employed, incorporating hydrophilic poly(2-(methacryloyloxy)ethyl phosphorylcholine) (PMPC) with hydrophobic poly(3-methoxypropyl acrylate) (PMPA). The synthesized diblock copolymers feature a PMPC block with a degree of polymerization (DP) of 100 and a PMPA block with DP (=) values of 171 and 552. The hydrophilic PMPC block exhibits biocompatibility, such as inhibition of platelet and protein adsorption, because of its hydrophilic pendant zwitterionic phosphorylcholine groups that have the same chemical structure as cell membrane surfaces.

Development of a microbiome for phenolic metabolism based on a domestication approach from lab to industrial application.

Despite a lot of efforts devoted to construct efficient microbiomes, there are still major obstacles to moving from the lab to industrial applications due to the inapplicability of existing technologies or limited understanding of microbiome variation regularity. Here we show a domestication strategy to cultivate an effciient and resilient functional microbiome for addressing phenolic wastewater challenges, which involves directional domestication in shaker, laboratory water test in small-scale, gas test in pilot scale, water test in pilot scale, and engineering application in industrial scale. The domestication process includes the transition from water to gas, which provided complex transient environment for screening of a more adaptable and robust microbiome, thereby mitigating the performance disparities encountered when transitioning from laboratory experimentation to industrial engineering applications.

Membrane-targeted push-pull azobenzenes for the optical modulation of membrane potential.

We introduce a family of membrane-targeted azobenzenes (MTs) with a push-pull character as a new tool for cell stimulation. These molecules are water soluble and spontaneously partition in the cell membrane. Upon light irradiation, they isomerize from trans to cis, changing the local charge distribution and thus stimulating the cell response.

Development of a multifunctional and sustainable pterostilbene nanoemulsion incorporated chitosan-alginate food packaging film for shiitake mushroom preservation.

The pervasive use of petroleum-based food packaging has caused significant ecological damage due to their unsustainability and non-biodegradability. Polysaccharide-based biodegradable materials are promising alternatives, but low hydrophobicity and functional properties limit their practical applications which can be overcome by incorporation of phytochemical(s). Therefore, by leveraging the strong antioxidant and antibacterial potential of pterostilbene (PTB), we have developed PTB nanoemulsion (NE) incorporated chitosan/sodium alginate (CS/SA) film for food packaging applications.

A CRISPR/Cas12a-based direct transverse relaxation time biosensor via hydrogel sol-gel transition for Salmonella detection.

This research developed a magnetic relaxation switching (MRS) biosensor based on hydrogel sol-gel transition and the CRISPR/Cas12a system (MRS-CRISPR) to detect Salmonella. Herein, the alkaline phosphatase (ALP) labeled with streptavidin was captured by the biotin-modified DNA on magnetic nanoparticles (MNPs) surface, which generated an acidic environment via enzymatic reaction to release Ca and induced the transformation of alginate sol to hydrogels. In contrast, Salmonella activated the trans-cleavage activity of the CRISPR/Cas12a system, interrupting the capture of ALP and the subsequent sol-gel transition.

The leakage of Liquid scintillator exudates has brought potential harm to the environment. Attributed to the large specific surface area and high modifiability, high-performance adsorbents based on metal-organic frameworks (MOFs) can effectively remove organic pollutants. In this work, we use different functional groups to prepare the material of UIO-66(Zr).

Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.
