Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Electronic Modulation of CoNi Nanoparticles by N‐Doped Carbon for Efficient Lignin Hydrogenolysis to Aromatic Monomers

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

Investigations of characteristics and applications of chirped and phase-shifted fiber Bragg gratings [PDF]

open access: yes, 2008
相移光纤光栅是指在光纤光栅的某些点,通过采用一些方法破坏其周期的连续性而得到的,这些不连续的连接会产生相移。目前所研究的相移光纤光栅仍停留在均匀Bragg光栅上引入相移点,而本文研究的啁啾相移光纤光栅是在啁啾光栅上引入相移点,并与普通相移光纤光栅的光谱特性进行了比较。啁啾相移光纤光栅不仅具有普通相移光纤光栅的一些重要的特征,而且其反射带宽和透射窗的带宽可以根据需要在很宽的范围设计。本文的工作对设计新型啁啾相移光纤光栅器件提供了理论依据。 第一章综述了光纤光栅的发展背景、分类和制作方法 ...

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.
