Integrated pressure relief technology for rock burst and gas outburst coordinated control in ultra-thick coal seams under spatially isolated rock pillar areas [PDF]
With the increasing depth of coal mining and the complexity of mining technical conditions, some mines are facing dual dynamic disasters of rock burst and coal and gas outburst, which exhibits a mutually coupled inducing trend.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Feedback mechanism of front abutment stress on filling rate of backfilling body in coal burst mine [PDF]
High stress is the main reason for high frequency of rock burst in deep coal mines. Backfilling mining serves as an effective method to control roof strata movement, alleviate the degree of stress concentration, and reduce the failure of surrounding rock

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Engineering the semiconductor/dielectric interface is crucial for advancing two‐dimensional (2D) nanoelectronics, where device performance is predominantly governed by interfacial defects and dielectric coupling. Optoelectronic doping based on carrier trapping at the h‐BN/SiO2 interface has enabled non‐volatile and reversible carrier ...

Shuitu Baochi Xuebao, 2018 坡面水流的输沙能力是影响土壤侵蚀过程的重要参数之一，加强坡面集中水流输沙能力的研究有助于深入理解集中流发生机理，并为防治集中流侵蚀发生提供科学依据。采用室内集中流放水冲刷试验，以黄土高原典型黄绵土为研究对象，研究了集中流输沙能力与放水流量和坡度以及与单宽流量和坡度之间的关系，同时对集中流水力参数和输沙能力的相应关系进行了研究。结果表明:集中流输沙能力随着坡度和放水流量的增加而增加。多元统计分析建立输沙能力与坡度和放水流量之间的幂函数关系发现坡度指标对输沙能力相对放水流量影响更大，而在坡度和单宽流量作用下，

Shiyou jixie, 2014 通过对双金属密封结构进行失效分析，得出失效的主要原因是：密封结构内部支撑角度和倒角半径的大小设计不合理导致弹性元件上的应力过大和应力集中，加速了弹性元件磨损和老化。利用有限元分析软件Workbench分析了O形橡胶圈上最大Mises应力和最大剪切应力在不同支撑角度和倒角半径下的分布情况，并对支撑角度和倒角半径进行了优选。分析结果表明，双金属密封结构的支撑角度和倒角大小对O形橡胶圈的应力影响较大；当支撑角度为15°、倒角半径为0.3 mm时，O形橡胶圈最大Mises应力和最大剪切应力最小 ...

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.
