Journal of the agricultural chemical society of Japan, 1938 5mgのAscorbin酸の37±1°に於ける自己酸化に對しVitamin A原液(100,000 I.U.)を0.0～0.2cc作用せしむる時0.0～0.0005ccまでは自己酸化抑制作用は發現せず, 0.001ccに於いて漸く發現し而して0.12ccまではVitamin Aの作用量と共に抑制作用は増大し0.12ccに於いて最大點に達し0.14cc以上に於いては抑制作用は消滅し酸化促進作用と化し而も此の作用は量比的である.但し本實驗に於てはVitamin AのAceton溶液を用ゐたから實驗値に對して幾分の誤差はまぬかれないであらう.

Advanced Functional Materials, EarlyView.There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Backbone Heterojunction Photocatalysts for Efficient Sacrificial Hydrogen Production
Advanced Functional Materials, EarlyView.Herein, a ‘single‐component’ organic semiconductor photocatalyst is presented in which a molecular donor is bonded to a polymer acceptor. The resultant material demonstrates exceptional photocatalytic activity for hydrogen evolution in aqueous triethylamine with an outstanding external quantum efficiency of 38% at 420 nm.

Tailoring the Properties of Functional Materials With N‐Oxides
Advanced Functional Materials, EarlyView.The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.
