Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

Advanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

Advanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Hydrogen‐Bond‐Rich Supramolecular Multiblock Copolymers Facilitate Rapid Zn2+ Migration in Quasi‐Solid‐State Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...

Riboflavin requirements are increased during endurance physical training

Riboflavin requirements are increased during endurance physical training
本研究は、リボフラビン必要量が運動時に実際に増大するか否かを検討した。持久的運動トレーニング時に、尿中リボフラビン排泄を促進するリボフラビンの付加摂取量と体内リボフラビン飽和点の変動が、それぞれ観察された。被験者は、健康な成人男子6名 (実験1)または5名(実験2)であった。実験1では、ベースラインのリボフラビン摂取量(0.55 mg per energy 1,000 kcal)が段階的に運動期に増量された。実験2では、0.35 mg/1,000 kcalのリボフラビン摂取量が、非運動期と運動期でそれぞれ段階的に増量された。運動期では、被験者は15時～17時の間に最大酸素摂取量の50%を目標強度として100分間の自転車運動を行った。 実験1では、運動期の尿中リボフラビン排泄量が、ベースライン(0 ...

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

Advanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.
