Studies on Ascorbic Acid. VI

open access: yesJournal 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.

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

open access: yesAdvanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...
