Organic Mixed‐Valence π‐Electron Systems—Current Status and Challenges

open access: yesAsian Journal of Organic Chemistry, Volume 15, Issue 10, October 2026.
This review discusses the progress and challenges in organic mixed‐valence π‐electron systems, focusing on trends such as the exploration of multi‐redox‐centered mixed‐valence multi‐radical states arising from the interplay between charge transfer and spin interactions and the realization of novel mixed‐valence states through the effective utilization ...

Environmental Factors Have a Stronger Influence on the Coral Holobiont in Comparison to Geographic Distance Along a 15,000‐km East‐to‐West Transect Through the Coral Triangle, Pacific and Indian Oceans

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Aim To determine the factors that structure coral‐associated microbial communities (bacteria and Symbiodiniaceae). These microbial communities play critical roles in reef ecosystem function, yet the relative importance of environmental versus geographic drivers in structuring these communities across large spatial scales remains poorly ...

Performance Analysis of Underlaid Full-Duplex D2D Cellular Networks

open access: yesIEEE Access, 2019
This paper investigates the benefits of incorporating underlaid full-duplex (FD) device-to-device (D2D) communications into cellular networks. Toward this end, we provide an analytical performance characterization of underlaid D2D cellular networks where

Steric Effects in Isopropyl‐Substituted (β‐Diketiminato)Iron Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.
An isopropyl‐substituted β‐diketiminate ligand is shown to integrate aspects of its methyl and tert‐butyl counterparts in the preparation of iron complexes. As in the methyl system, it is synthesized in a single step but, like the tert‐butyl analog, it provides sufficient steric shielding to support otherwise unstable compounds.

Enhancing Content Caching in D2D Networks: A Stackelberg Game Approach With Wireless Energy Transfer and Social Awareness

open access: yesIEEE Access
In a cache-enabled device-to-device (D2D) network, cooperative D2D caching holds promise for reducing data traffic and overall waiting time. However, the act of content caching and transmission can impose a drain on battery power, thereby diminishing ...

Power control for full-duplex D2D communications underlaying cellular networks

open access: yesDianxin kexue, 2017
Device-to-device (D2D) communications that based on the wireless full-duplex transmission mode can not only reuse the cellular users' spectrum resource, but also significantly improve the spectral efficiency and the system throughout in wireless cellular

Physical layer security of modify-and-forward cooperative D2D networks based on transmit antenna selection

open access: yesDianxin kexue
To further improve the physical layer security (PLS) performance of decode-and-forward (DF) cooperative device-to-device (D2D) network that shared spectrum resources with cellular network, a modify-and-forward (MF) cooperative D2D-cellular PLS model was ...

基于发射天线选择的修改转发协作D2D网络的物理层安全

open access: yesDianxin kexue
为了进一步提升与蜂窝网络共享频谱资源的解码转发(decode-and-forward,DF)协作终端直通(device-to-device,D2D)网络的物理层安全(physical layer security,PLS)性能,提出了一种D2D发送端采用发射天线选择(transmit antenna selection,TAS)的修改转发(modify-and-forward,MF)协作D2D-蜂窝网络PLS模型。配备多根发射天线的D2D发送端采用TAS技术 ...
