Double charge flips of polyamide membrane by ionic liquid-decoupled bulk and interfacial diffusion for on-demand nanofiltration

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Март 13, 2024

Fine design of surface charge properties polyamide membranes is crucial for selective ionic and molecular sieving. Traditional face limitations due to their inherent negative limited modification range. Herein, we report a facile liquid-decoupled bulk/interfacial diffusion strategy elaborate the double flips membranes, enabling on-demand transformation from inherently highly positive near-neutral charges. The key these lies in meticulous utilization liquid that decouples intertwined diffusion, enhancing interfacial while inhibiting bulk diffusion. These charge-tunable can be customized impressive separation performance, example, profound Cl

A Rotating Triboelectric Nanogenerator Driven by Bidirectional Swing for Water Wave Energy Harvesting

Small, Год журнала: 2023, Номер 19(52)

Опубликована: Авг. 30, 2023

Due to the simple installation and convenient maintenance, floating water wave energy harvesting devices have significant economic advantages. Mass power density is most important index evaluate advancement of devices. Herein, a self-adaptive rotating triboelectric nanogenerator (SR-TENG) with compound pendulum functional gear-set provided for harvesting. First, structure low center gravity high moment inertia obtained by geometric design mechanical study. Besides, compared previous one-way clutch, SR-TENG can harvest twice kinetic utilization through gear-set. Importantly, depending on design, obtains average mass 45.18 mW kg-1 under frequency driving conditions, which about 10 times reference electromagnetic generator similar size. This result shows that has advantage in small These findings provide an example

Scarcity and quality risks for future global urban water supply

Landscape Ecology, Год журнала: 2024, Номер 39(2)

Опубликована: Янв. 29, 2024

Abstract Context Supply of freshwater to the world’s cities is increasingly affected by human pressures and climate change. Understanding effects change on global urban water scarcity quality risks in an integrated way important. Objectives The objective this study assess security for 304 large (population > 1 million) across world 2015 2050. Methods We assessed according demand availability, evaluated supply terms population density, cropland fertilization, landscape patterns source watersheds. In addition, impacts were quantified using contribution analysis. Results found that about 90% these faced 2015. number facing risk was three times risk, nearly a quarter dual risks. From 2050, 88.8–99.7% projected face rising with one-third Increase main cause risk; growth crop fertilization watersheds reasons risk. Conclusions There urgent need promote conservation areas, implement sustainable planning governance, improve infrastructure, refine ecological compensation regimes achieve security.

Bidirectional Rotating Turbine Hybrid Triboelectric‐Electromagnetic Wave Energy Harvester for Marine Environment Monitoring

Advanced Energy Materials, Год журнала: 2024, Номер 14(26)

Опубликована: Май 19, 2024

Abstract Hydrokinetic energy, a vital renewable resource, holds promise for addressing fossil fuel shortages to ensure sustainable future. This study proposes an efficient and stable ocean wave energy harvesting system that combines triboelectric nanogenerator (TENG), electromagnetic generator (EMG) with planetary gear system, driving turbine. The turbine transforms the up‐and‐down motion in water into continuous, unidirectional rotational motion. An EMG device accelerated by further ensures sustained output at very low frequencies (0.25 Hz) boosts upper limit of power generation medium high frequencies. Under conditions 1 Hz frequency, TENG component yields up 2200 V 122 µA, while average is 15 80 mA. Remarkably, entire maintains steady uninterrupted even extremely Hz). peak outputs components are 115 350 mW, respectively, densities 32.55 329.78 W m −3 , surpassing prior achievements. research demonstrates self‐powered applications provides method amplify forces, enhancing capabilities practical marine environmental monitoring.

Water quality prediction based on sparse dataset using enhanced machine learning

Environmental Science and Ecotechnology, Год журнала: 2024, Номер 20, С. 100402 - 100402

Опубликована: Март 1, 2024

Water quality in surface bodies remains a pressing issue worldwide. While some regions have rich water data, less attention is given to areas that lack sufficient data. Therefore, it crucial explore novel ways of managing source-oriented pollution scenarios with infrequent data collection such as weekly or monthly. Here we showed sparse-dataset-based prediction using machine learning. We investigated the efficacy traditional Recurrent Neural Network alongside three Long Short-Term Memory (LSTM) models, integrated Load Estimator (LOADEST). The research was conducted at river-lake confluence, an area intricate hydrological patterns. found Self-Attentive LSTM (SA-LSTM) model outperformed other learning models predicting quality, achieving Nash-Sutcliffe Efficiency (NSE) scores 0.71 for CODMn and 0.57 NH3N when utilizing LOADEST-augmented (referred SA-LSTM-LOADEST model). improved upon standalone SA-LSTM by reducing Root Mean Square Error (RMSE) 24.6% 21.3% NH3N. Furthermore, maintained its predictive accuracy intervals were extended from Additionally, demonstrated capability forecast loads up ten days advance. This study shows promise improving modeling limited monitoring capabilities.
