Computerized nailfold video‐capillaroscopy in type 2 diabetes: A cross‐sectional study on 102 outpatients 计算机化甲襞视频毛细血管镜在2型糖尿病中的运用: 对102例门诊患者的横断面研究

open access: yesJournal of Diabetes, Volume 15, Issue 10, Page 890-899, October 2023., 2023
Highlights Patients with type 2 diabetes (T2D) are prone to developing chronic diabetes‐related complications at the microvascular and macrovascular levels. The Computerized Nailfold Video‐Capillaroscopy (CNVC) provides specific information on both quantitative and qualitative characteristics of microvasculature at the level of fingers.

大气压氩气纳秒脉冲针—水结构气液放电特性研究

open access: yesGaoya dianqi, 2022
为了在提高放电等离子体活性的同时保持较为稳定的放电,文中利用纳秒脉冲电源驱动大气压氩气中针—水结构气液放电,研究了不同脉冲电压和频率下的放电电学特性、发光图像和发射光谱强度,并讨论了相关参数对放电特性的影响原因。结果表明:在氩气纳秒脉冲气液放电中,脉冲电压和频率不会对放电模式产生影响。随着脉冲电压的增大,上升沿电流、下降沿电流和平均功率均增大,且上升沿电流总是大于下降沿电流;当脉冲频率增大时,上升沿电流和平均功率增大,下降沿电流逐渐减小。等离子体特性方面,在不同脉冲电压和频率下均测到了较强的Ar(4p ...

Synthesis of graphene by PECVD and research on the performance of graphene-based Li-ion batteries [PDF]

open access: yes, 2016
石墨烯是由碳六元环形成的二维蜂窝状晶格结构,只有一个碳原子的厚度,是第一种真正意义上的二维材料。由于这种特殊的结构,石墨烯拥有一些优异的物理和化学性能,如优异的力学性能、较好的柔韧性、良好的导电性能、很高的电子迁移率、较大的杨氏模量。这使得石墨烯在纳米电子器件、超级计算机、太阳能电池、透明电极等的应用方面具有很高的应用价值。但是所有这一切的前提是需要大规模制备出高质量的石墨烯。目前,石墨烯制备方法已有很多,但是要想实现石墨烯的产业化,就必须针对不同的应用实现石墨烯的大规模、高质量、可调控生长 ...

From Microstructure to Macroscopic Performance: A Comprehensive Study on Low‐K Oxide‐Doped BNT–LST–NN Ceramics for Energy Storage

open access: yesRare Metals, EarlyView.
ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...
