Effect of Nitrogen Doping on the Proton‐Irradiation Stability of Carbon Nanowalls

open access: yesAdvanced Materials Interfaces, EarlyView.
Proton irradiation effects in carbon nanowalls are systematically compared with nitrogen‐doped counterparts over a wide fluence range. While both systems maintain structural integrity, nitrogen incorporation alters the functional response under irradiation.

Synergistic effects of Fe-Mn binary oxide for gaseous arsenic removal in flue gas

open access: yesEcotoxicology and Environmental Safety, 2021
High-efficient and economic sorbents are highly desired for arsenic (As) emission control in flue gas from coal-fired power plant. A series of Fe-Mn binary oxides were prepared by a facile method, and their behaviors for gaseous arsenic removal in flue ...

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

A hollow structure WO3@CeO2 catalyst for NH3-SCR of NOx

open access: yesCatalysis Communications, 2021
Constructing a hollow structured Ce-based catalyst is an effective way to result in an efficient catalytic system for the selective catalytic reduction of NOx using NH3 (NH3-SCR). A WO3@CeO2 catalyst with hollow structure was successfully developed using

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions

open access: yesAdvanced Robotics Research, EarlyView.
Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.
