Sustainable synthesis of Ce-La loaded ontoCitrus limonfor phosphate removal: Performance and regeneration studies.

Efficient phosphate (P) treatment and resource recovery from water are crucial environmental challenges in water pollution management. In this study, a bimetallic La-Ce nanoparticle Citrus limon residue-based biosorbent was developed through a solvothermal synthesis method, using fruit waste as the raw material. This research work revealed that the surface of the agricultural waste became rough and uniformly layered through La and Ce after modification.

Zwitterionic Binder-Engineered Interfaces Enable Anti-Pulverization and Long-Cycling Anode-Free Zn Batteries.

Anode-free zinc batteries (AFZBs) offer exceptional theoretical energy density, yet suffer from severe structural pulverization and dendritic growth during cycling, leading to rapid capacity decay and poor reversibility. To address these challenges, this work proposes a novel zwitterionic binder strategy that concurrently suppresses Zn pulverization and stabilizes the electrode-electrolyte interface. Incorporation of a rationally designed zwitterionic polymer binder (ZPB) endows the engineered Zn anode with unprecedented mechanical robustness and homogeneous ion flux distribution.

Isolated Band Narrowing toward High-Performance 2D SiS p-MOSFETs with Steep-Slope Switching.

As silicon transistors approach their scaling limits, two-dimensional (2D) materials have emerged as promising candidates for sub-10 nm devices. However, 2D p-type transistors often exhibit low on-state current and large subthreshold swing (SS) compared with the n-type counterparts, limiting the development of energy-efficient logic circuits. Here, we present that 2D SiS with a unique isolated valence band edge can be used to realize steep-slope switching and high-performance MOSFETs.

Tailoring the Oxygen Vacancy Distribution in Se-Doped RuO to Enhance Its Stability in Acidic Water Electrolysis.

Developing durable ruthenium (Ru)-based catalysts for proton exchange membrane water electrolyzer (PEMWE) remains challenging due to irreversible Ru dissolution and lattice oxygen instability. Although elemental doping is a general method to improve stability, it inadvertently induces oxygen vacancies (Vs), which are randomly distributed in the nanocatalyst. Notably, the impact of V distribution on the stability of Ru-based catalysts remains unresolved.

2D Molybdenum Disulfide Embedded Photonic Crystal Fiber for all-Fiber Phase Retarder.

The integration of 2D materials with optical fibers enables multifunctional fiber devices, such as polarizers, modulators, and sensors. Recent advances in direct vapor deposition growth further enhance light-2D material interactions to centimeter-scale lengths, overcoming the micrometer-scale limitations of transferred 2D materials. However, conventional methods for growing 2D materials in fibers typically produce isotropic material architectures due to uniform precursor deposition, limiting applications that require birefringence, such as a phase retarder.

Engineering surface and subsurface oxygen vacancies of CeZrO solid solution for enhanced total toluene oxidation.

Most studies have shown that oxygen vacancies on CeZrO solid solution are important for enhancing the catalytic oxidation performance. However, a handful of studies investigated the different roles of surface and subsurface oxygen vacancies on the performance and mechanisms of catalysts. Herein, a series of zirconium doping on CeO samples (CeO, CeZrO, and CeZrO) with various surface-to-subsurface oxygen vacancies ratios have been synthesized and applied in toluene catalytic oxidation.

Adaptive exponential weighted composite sliding mode-based direct yaw moment control for four-wheel independently actuated autonomous vehicles.

This paper introduces a novel Direct Yaw Moment Control (DYC) scheme for autonomous vehicles with Four-Wheel Independent Actuation (FWIA). In the upper-layer control strategy, an Adaptive Exponential Weighted Composite Sliding Mode Controller (AEWC-SMC) is proposed by incorporating a nonlinear weighting factor into the sliding mode surface and designing a composite reaching law. For the lower-layer torque allocation, a Dynamic Weight Minimum Energy Allocation (DWMEA) method is developed, which achieves optimal four-wheel torque distribution without iterative computation.

Metal-free photoinduced ROMP-enabled electrochemical aptasensor for ultrasensitive detection of endotoxin.

Accurate diagnosis of Gram-negative bacterial infections hinges critically on endotoxin detection, with ultrasensitive quantification playing a pivotal role in clinical diagnosis, precision therapy, food safety and environmental monitoring. Herein, we pioneer an electrochemical aptasensing platform based on metal-free photoinduced ring-opening metathesis polymerization (MF photo-ROMP) for endotoxin analysis. Specifically, the aptamer is employed for selective capture of endotoxin, whose glycan chain is then modified with 4-formylphenylboronic acid via boronate affinity.

Facet-Dependent CoO Nanocrystals for Efficient and Highly Selective Photothermal CO Hydrogenation.

Photothermal CO hydrogenation with green H for conversion into fuels or chemicals is a promising technology for efficient CO conversion with low energy input. However, low catalytic activity and selectivity are one of the difficulties in photothermal catalysis, so it is crucial to develop photothermal catalysts with high catalytic activity. By employing crystalline surface engineering, specific highly active crystalline surfaces can be exposed, which have more active sites and can improve the photothermal performance of the catalysts to some extent.

The FTR dual-loop architecture based on SID-NLMS can achieve a threshold of 0.0001°/s and an ARW of 0.006°/√h for MEMS QMG.

With the introduction of technologies such as structural optimization and error correction, the performance of the MEMS quad-mass gyroscope (QMG) has significantly improved, while noise has gradually become a critical factor limiting its performance. For ease of analysis, this paper categorizes noise into two types: noise at the signal detection end and noise at the excitation end. Firstly, a closed-loop noise model for QMG is established, and the effects of these two types of noise on the dynamic and static performance of QMG are investigated.

Highly Stable Electrosynthesis of Hydrogen Peroxide Adapted to Fluctuating Renewable Energy.

The integration of renewable energy with electrocatalytic technology affords an effective pathway to reduce carbon emissions and enhance energy efficiency, thereby promoting the green electrification of the chemical industry. However, the inherent contradiction between the fluctuating nature of renewable energy and the need for stable operation in electrochemical processes significantly hinders their development and implementation. To mitigate this, we propose a robust two-electron oxygen reduction reaction system using O-coordinated Co single-atom catalysts for the electrosynthesis of environmentally friendly hydrogen peroxide.

To overcome this limitation, a multiscale confinement strategy is developed that integrates intramolecular flexible encapsulation with intermolecular rigid immobilization. Dendronized donor-acceptor molecules are engineered with alkyl-chain-carbazole dendrons to achieve intramolecular encapsulation.
