Fabrication of flexible transparent electrodes(FTEs) is one of the core technologies in the field of flexible electronics. Among multiple choices of FTEs, poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonic acid)(PEDOT:PSS) has shown its promising application in roll-to-roll manufacturing. A simple yet effective method for substantially boosting the conductivity of these conducting polymer films without causing large-domain aggregations is by adding ethylene glycol(EG) as dopant. Herein, we investigated in detail the effects of the secondary solvent of ethylene glycol(EG) on the optical and electrical characteristics of PEDOT:PSS films. The modified PEDOT:PSS FTEs were deposited using drop-coating techniques as it had greater compatibility for large-area samples than the conventional spin-coating method did. The 6% EG-doped PEDOT:PSS FTE via drop-coating method achieved a high figure of merit(FoM) value of 47.24 and the devices fabricated using the optimal PEDOT:PSS FTE yielded a high power conversion efficiency(PCE) of 8.89%, mostly attributed to the modified PEDOT:PSS films that had excellent optical and electrical characteristics with low surface roughness. These results suggested that EG-doping could effectively boost the conductivity of PEDOT:PSS films and that the modified PEDOT:PSS FTE is suitable for roll-to-roll manufacturing in the future.

为了公平合理的分配道路交通资源,避免投资决策不合理引发'贫者愈贫,富者愈富'的马太效应。基于等效理念,分析了人口规模及聚集程度、区域面积及地形、经济水平与资源潜力对公路网规模公平性的影响,提出等效人口、等效面积、等效经济的概念,并分别采用人口数量修正法、面积修正法、量化资源潜在经济价值方法,分别对其进行量化;运用基尼系数法对公路网规模公平性进行评价,并以云南省公路网为例进行实例验证。分析结果表明:利用给出的方法计算云南省公路网的等效人口、等效面积与等效经济的基尼系数分别为0.185、0.232、0.332,与原来的0.199、0.184、0.348相比,公路网规模在人口、区域面积、经济方面分布分别达到绝对公平、相对公平、相对合理,充分考虑了基于等效理念的等效人口、等效面积、等效经济对公路网规模公平性的影响,能够更加合理的反映公路网规模分布的公平性。

Ovarian endometrioma（OE）, also known as “chocolate cysts,” is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations. We identified notable alterations in cell type-specific proportions and molecular signatures associated with OE. Notably, the activation of IGFBP5+macrophages with pro-inflammatory properties, NK cell exhaustion, and aberrant proliferation of IQCG+and KLF2+epithelium are key features and may be the potential mechanisms underlying the pathogenesis of OE. Collectively, our data contribute to a better understanding of OE at the single cell level and may pave the way for the development of novel therapeutic strategies.

作者： zi-yi Ding National Research Tomsk Polytechnic University

We study the absorption of hydrogen of metal by the permeability method. With the help of the gas reaction controller(GRC), the absorptive capacity of hydrogen, which is a function of time, temperature and pressure, can be recorded. The effect of the performance of the hydrogen permeability of AlN coating on the titanium alloy surface structure is *** the research, the AlN is selected to be added to the titanium alloy sample VT6, and the properties of the titanium alloy are investigated, and the hydrogen absorption rate of the coating is calculated by performing the hydrogen saturation of the test sample. The results show that under 600℃ the AlN film reduces the hydrogen absorption rate of titanium alloy and improves the surface properties of VT6 alloy.

Combined kinematic and static analysis of an articulated lower limb traction device for a rehabilitation robotic system

引用

Science China(Technological Sciences) 2021年第6期64卷 1189-1202页

作者： LI Yuan zi Bin YANG ZhengMeng ge Jeffrey School of Mechanical Engineering Hefei University of TechnologyHefei 230009China Intelligent Interconnected Systems Laboratory of Anhui Province(Hefei University of Technology) Hefei 230009China Department of Mechanical Engineering Stony Brook UniversityStony Brook NY 11794-2300USA

This paper presents a design of an articulated lower limb traction device(ALLTD) with joint torque generators for a cable-driven parallel rehabilitation robotic system(CDPRRS). An earlier version of the ALLTD uses a rigid link to model the lower limbs of a patient. This paper extends this scenario to include articulations in the lower limbs and analyzes the resulting two-link mechanism. Due to the force-displacement coupled structure, the inverse and forward kinematics of the ALLTD model are analyzed in combination with the requirement for static force balance. Examples using the limb parameters of Chinese adults are provided to show the efficacy of our model. The workspaces and cable tensions of the model indicate that the ALLTD could satisfy the rehabilitation training needs of patients with various lengths of lower limbs.
