Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

open access: yesEcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Combined Attacks and Countermeasures [PDF]

open access: yes, 2010
Logical attacks on smart cards have been used for many years, but their attack potential is hindered by the processes used by issuers to verify the validity of code, in particular bytecode verification. More recently, the idea has emerged to combine logical attacks with a physical attack, in order to evade bytecode verification.

Overcoming Cell Fixture Challenges in High‐Pressure Operation of Solid‐State Batteries

open access: yesEnergy Science &Engineering, EarlyView.
Accurate application of high uniaxial pressure remains a limiting factor in large‐format solid‐state battery testing. A spring‐loaded fixture employing deflection‐based pressurization enables precise, homogeneous, and reproducible pressure application without expensive in‐fixture sensors, providing a robust framework for systematic investigation of ...

Elevator dynamic monitoring and early warning system based on machine learning algorithm

open access: yesIET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

PPARγ-responsive luciferase reporter system for high-throughput screening of chemical toxins with potential pulmonary fibrosis effects

open access: yesEcotoxicology and Environmental Safety
Background: Pulmonary fibrosis (PF) is a progressive and fatal lung disorder, and emerging evidence suggests that dysregulation of peroxisome proliferator-activated receptor gamma (PPARγ) plays a critical role in its pathogenesis.

Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications

open access: yesExploration, EarlyView.
There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive

Strategies for Identification and Mitigation of Sanguinarine in Mustard Oil Adulterated by Argemone—A Comprehensive Review

open access: yesFood Chemistry International, EarlyView.
Sanguinarine, a toxic alkaloid present in argemone, can lead to epidemic dropsy or chronic diseases through DNA intercalation and immune system suppression. Regulatory efforts face challenges due to economic motivations for adulteration as well as technical, social, and infrastructure barriers.
