Positive findings for plasma polymer (meth)acrylate thin films in heritage protective applications

Plasma technology is an innovative environmental friendly process that can be an option to the conventional methods for materials’ processing. Nonequilibrium low pressure plasma found efficiency as a nondestructive method for the treatment of different materials, many of them belonging to the cultural heritage, in some proper operations such as: atomic-level cleaning, decontamination, thin film deposition. In the paper, the low pressure nonequilibrium plasma is applied for the deposition of plasma polymer poly(methyl methacrylate-co-ethyl acrylate) P(MMA-co-EtA) thin films on natural aged paper, with the consolidation and protective aim. To verify the plasma polymer applicability for paper protection and consolidation, the film is aged accelerated by UV radiation and the structural and morphological changes are evaluated by FTIR spectroscopy, color/gloss measurement, contact angle and AFM.     

等离子喷涂NiCrAl/Cr2O3-8%TiO2涂层残余应力模拟分析

建立了模拟涂层残余应力的数学模型,对等离子喷涂不同厚度NiCrAl/Cr2O3-8%TiO2涂层的残余应力进行了模拟,模拟结果表明:由于涂层与基体的热膨胀系数不匹配等原因,在界面等区域存在严重的应力集中,涂层内部的残余应力水平,随涂层厚度增加而增加,涂层中的径向、轴向、切向应力均为压应力,径向应力是最主要的应力。     

PDP显示动态图像时的干扰及解决措施

文章介绍了彩色等离子显示器显示动态图像时的干扰及其形成机理,主要将AC-PDP和CRT发光的异同进行了比较和研究,指出了彩色AC-POP显示动态图像时干扰的出现是由子场驱动重显不同灰度造成的,彩色AC-PDP在显示运动物体时,由于人眼的视觉惰性就会出现不同时间发光的不均匀,从而在人眼视点跟随运动图像移动时,在视网膜上出现了虚假的轮廓干扰.文章最后介绍了显示动态图像时减少干扰的方法.

Assessment of Endothelial Dysfunction in Health and Disease; Using Various Parameters

Conditions like hypertension, atherosclerosis and diabetes are known to be the result of endothelial dysfunction which could begin early in the life of an individual. The markers of endothelial dysfunction studied in the present work are plasma hemoglobin, serum high sensitivity C-reactive protein (hsCRP) and plasma nitrite and nitrate. We studied the onset of endothelial dysfunction with increase in age as well as in disease condition like newly detected hypertensives and of hypertensive diabetic patients. The mean plasma hemoglobin and hsCRP values were found to increase with age. hsCRP and plasma hemoglobin levels were significantly higher in patient groups as compared to aged-matched controls. On the other hand nitrate and nitrite was significantly higher in patients who suffered from both diabetes and hypertension together and nitrate values were significantly lower in patients who suffered from hypertensive alone. Plasma hemoglobin and hsCRP are associated with endothelial dysfunction and increases both with age as well as in disease condition.

Surface treatment of 0Cr19Ni9 stainless steel SMAW joint by plasma melting

Micro-plasma arc surface melting of 0Cr19Ni9 shielded metal arc welding joint with a micro-plasma arc welder produced a thin surface melted layer with a refined microstructure. The surface treatment changed the anodic polarization behavior in 0.5 mol/L H2SO4 solution. The polarization tests showed that for the as-welded joint both the heat-affected zone and the weld metal decreased in resistance to corrosion compared with the as-Received parent material while for the micro-plasma arc surface melted joint the corrosion resistance increased significantly. This increase in corrosion resistance is attributed to the rapid solidification of the melted layer. Rapid solidification of the melted layer refines its microstructure, decreases its microsegregation, and inhibits the precipitation of chromium carbides at the grain boundaries.received parent material while for the micro-plasma arc surface melted joint the corrosion resistance increased significantly.

水平电偶极子在覆盖有等离子体的良导体上产生的电磁场的研究

本文研究了水平电偶极子在覆盖有等离子体的良导体上产生的电磁场。总电磁场包括了直射波,理想反射波,侧面波和缺陷表面波。因为等离子体的折射系数是随频率变化的复杂函数,所以用于计算缺陷表面波的极点函数的解也是频率的函数。研究了频率对极点方程及其解的影响,并分别计算了直射波,理想反射波和侧面波之和、总场强、以及缺陷表面波的值。由于金属表面的介电常数可以在很宽的频率范围内表示为等离子体,所以本文的研究成果可以用于集成微带线电路或者微带天线等。
