    Optimizing electrical output performance of triboelectric nanogenerators by micro-/nano-morphology design and fabrication by Jiaxin Han, Xingyi Dai, Long-Biao Huang, Jianhua Hao

    Published 2025-01-01
    “…In efforts to augment the electrical output performance of TENGs and broaden their range of applications, researchers have endeavored to refine materials, surface morphology, and structural design. Among them, physical morphological modifications play a pivotal role in enhancing the electrical properties of TENGs by increasing the contact surface area, which can be achieved by building micro-/nano-structures on the surface or inside the friction material. …”

    Extreme functional specialization of fertile leaves in a widespread fern species and its implications on the evolution of reproductive dimorphism by Jacob S. Suissa, Noah Barkoff, James E. Watkins

    Published 2024-07-01
    “…In plants, the allocation of resources among maintenance, reproduction, and growth influences short‐term economics and long‐term evolutionary processes, especially during resource scarcity. The evolution of specialized structures to divide labor between reproduction and growth can create a feedback loop where selection can act on individual organs, further increasing specializaton and  resource allocation. …”

    Synthesis of Self⁃Supported Pt@Ni(OH)2 Catalysts and Their Electrocatalytic Hydrogen Evolution Performance for Water Splitting by Kangsheng HUANG, Ning WANG, Mingrui GUO

    Published 2025-06-01
    “…However,a systematic understanding of the structure–activity relationship between Ni(OH)₂ supports and Pt nanoparticles,as well as the impact of synthesis parameters on catalytic performance,remains lacking.This study focuses on the regulation of Ni(OH)₂ support phase evolution and Pt interfacial growth behavior by hydrothermal synthesis temperature.By analyzing the structure–performance relationship through the synthesis parameter–microstructure–catalytic performance correlation mechanism),the synergistic effects of temperature on the crystallinity of the support,Pt particle size distribution,and interfacial electronic structure were elucidated.Experimental results indicate that the Pt@Ni(OH)₂ catalyst synthesized at 100 ℃ exhibits outstanding HER activity in 1 mol/L KOH electrolyte,with overpotentials of only 5 mV at 10 mA/cm² and 62 mV at 100 mA/cm²,along with a Tafel slope of 70.0 mV/dec.After 50 hours of continuous operation,the electrode maintains nearly unchanged HER performance,demonstrating remarkable stability.…”

    Time-resolved spectroscopy uncovers deprotonation-induced reconstruction in oxygen-evolution NiFe-based (oxy)hydroxides by Dan Wu, Longfei Hu, Xiaokang Liu, Tong Liu, Xiangyu Zhu, Qiquan Luo, Huijuan Zhang, Linlin Cao, Jinlong Yang, Zheng Jiang, Tao Yao

    Published 2025-01-01
    “…This deprotonation behavior drives the formation of high-valence Ni3+δ species (0 <δ < 1), which subsequently serve as the active sites, thereby ensuring efficient oxygen evolution activity. This approach offers high-resolution insights of dynamic structural evolution, overcoming the limitations of extended acquisition times and advancing our understanding of OER mechanisms.…”

    A Comparative Study of Solid Electrolyte Interphase Evolution in Ether and Ester-Based Electrolytes for Na-ion Batteries by Liang Zhao, Sara I.R. Costa, Yue Chen, Jack R. Fitzpatrick, Andrew J. Naylor, Oleg Kolosov, Nuria Tapia-Ruiz

    Published 2025-07-01
    “…The results show that diglyme forms a thin, homogeneous, and stable SEI with a well-defined inorganic-organic bilayer structure, as opposed to ester-based electrolytes, which form a thicker, nonuniform, and dynamically changing SEI with randomly distributed inorganic-organic structure. …”

    Evolution of an agriculture-associated disease causing Campylobacter coli clade: evidence from national surveillance data in Scotland. by Samuel K Sheppard, John F Dallas, Daniel J Wilson, Norval J C Strachan, Noel D McCarthy, Keith A Jolley, Frances M Colles, Ovidiu Rotariu, Iain D Ogden, Ken J Forbes, Martin C J Maiden

    Published 2010-12-01
    “…Genealogical reconstruction of isolates from clinical infection, farm animals and the environment, revealed a three-clade genetic structure. The majority of farm animal, and all disease causing genotypes belonged to a single clade (clade 1) which had comparatively low synonymous sequence diversity, little deep branching genetic structure, and a higher number of shared alleles providing evidence of recent clonal decent. …”
