Ablation‐Immune Thermal Armor Via Microstructural‐Compatibility Design for Extreme Thermal Conditions

Advanced Science, EarlyView.
This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

Solution‐Processed Multi‐Junction Optoelectronic Synapses for Mode‐Switchable SWIR Neuromorphic Vision Sensing

Advanced Science, EarlyView.
A novel bias‐programmable shortwave infrared (SWIR) vision sensor is developed using multi‐junction colloidal quantum dots (QDs). Under varying applied voltage, the back‐to‐back rectifying junctions effectively tune trapping centers to switch the device between high‐speed photodetector and persistent synapse modes.

SWIFT Story of Sustainable Change: Handing over a new water network to a community in South Kivu, DRC

, 2016
The residents of Katungulu used to have to make a two-hour round trip to a contaminated river to collect water. Defecation took place mostly in the bush; the few latrines were dirty and poorly maintained; and hand-washing with soap or ash wasn’t ...

Governing the Recovery of Stalled Systems-of-Systems: ADAPT, a Dependency-Anchored Methodology, with Multi-Case Feasibility Illustrations

Systems
Systems-of-systems (SoSs) integrate constituents that retain operational and managerial independence, and that independence leaves their engineering artifacts prone to drift: changes fail to propagate, misalignment surfaces late, and outputs accumulate ...

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

Advanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

Synergistic Regulation of Deep‐Cycling‐Induced Zn Pulverization and Resting Galvanic Corrosion in Practical Lean Zinc Anodes

Advanced Science, EarlyView.
Benzotriazole (BTA) regulates Zn reduction kinetics and suppresses galvanic corrosion, simultaneously mitigating Zn pulverization during cycling and self‐corrosion during storage, thereby enabling lean Zn anodes with enhanced cycling stability and extended calendar life.
