Export controls and the energy transition: Aligning security and sustainability
Review of European, Comparative &International Environmental Law, EarlyView.Abstract This article examines how the accelerating use of export controls, once motivated by narrow security interests, can now affect the pace and success of the global energy transition. As strategic rivalry intensifies among the US, the EU and China, export controls increasingly target access to critical and emerging technologies such as advanced ...

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Review on Engineering Application Status of Gob-Side Entry Retaining Technology in China
Applied SciencesGob-side entry retaining (GSER) technology has been widely used in underground coal mines. However, the applicable conditions of GSER technology in practical engineering still need further clarification to prevent the safety hazards and significant economic losses caused by its failure. In this study, 587 application cases of GSER in China from 2000 to

Minor epic: Notes toward a different “Anthropoetry”
Anthropology and Humanism, Volume 51, Issue 1, June 2026.Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival

Advanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.Geminal dimethoxyethers react with pyrrolic nucleophiles in an efficient and clean reaction under anhydrous, mild conditions, which contrasts with the reactivity of the respective carbonyl compounds. Polymerization is effectively inhibited, providing access to dipyrromethanes, porphyrins, and calix[4]pyrroles that are easily purified.

An innovative approach for gob‐side entry retaining in deep coal mines: A case study
Energy Science & Engineering, 2019 Due to the complex geostress and mining conditions in the coal seam with depth of 800 m, stability of surrounding rock for gob‐side entry retaining is very difficult to achieve.
