Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence
Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.

Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,

The role of Mexico in the first oil shortage: 1918-1922, an international perspective [PDF]
In 1921 Mexico produced a quarter of world’s petroleum, making the country the second largest producer in the world, but by 1930 it only accounted for 3 per cent of world’s production.

A Survey of Petroleum Industry
その原料の95%を国外に仰いでいるわが国の石油工業は, 世界の石油情勢を刻々に反映している。世界の石油確定埋蔵量は年消費量の25倍で, 石油工業は一応健全であるとされている。世界の製油能力は消費量に対しやや不足している。わが国では, 太平洋岸製油所の再開以来, 外国会社との提携または連絡で目覚ましい製油能力の増大をみせ, 今年度末には約10万bbl/日に達するものとみられ, 航空用ガソリンや高級潤滑油以外は充分国内で製造できる。世界の原油の生産は巧緻をきわめた機構で計画され運営されており, わが国の輸入原油の62.7%は中東から, 20.7%は米国から, 残りの16.6%が東南アジァからのものである。輸入原油を運ぶ油槽船は31隻あるが, その牛数以上は戰標船で能率が悪く, 新船の建造が要求される ...
