采用红外吸收光谱、Raman光谱和51V静态固体核磁共振研究了La2O3对钒磷二元玻璃结构变化的影响。结果表明:钒作为主要的玻璃形成体构成基本网络,磷以孤立的磷氧四面体分散存在于钒为主体的玻璃网络中,磷氧四面体只与钒连接作用,钒在玻璃中主要以(VO3)n单链、(V2O8)n锯齿状链、VO4分枝和427VO?基团等形式存在,其中前两种基团占支配地位,对玻璃的性质起决定性影响,La2O3的引入破坏了网络平衡中间态的结构,(V2O8)n锯齿状链结构逐渐转化为(VO3)n单链,使玻璃的结构更加疏松。

综述了介质/金属/介质(dielectric/metal/dielectric,D/M/D)多层透明导电膜材料的特点、制备方法、研究进展与应用现状,重点比较讨论了 ITO/Ag/ITO、ZnS/Ag/ZnS 的膜系结构、光电性能、化学稳定性、热稳定性等特点,以及与国内外的研究差距。ITO/Ag/ITO、ZnS/Ag/ZnS 是目前光电性能最好,且无需引入过渡层的两种 D/M/D膜系,但有关其热稳定性的评价和研究存在不同的观点。用资源丰富、价格便宜、无毒的掺铝氧化锌(ZAO)薄膜取代含有价格昂贵的贵金属铟的掺锡氧化铟(ITO)薄膜,ZAO/Ag/ZAO 膜系结构的设计、薄膜制备、光电性能与 IMI 的对比研究是目前国内外 D/M/D 研究中的热点课题和 D/M/D 发展的主要方向。

为研究GeSe2-As2Se3-CdSe系统的玻璃形成区,制备了该系统系列的透红外玻璃样品,并用差示扫描量热法对玻璃样品进行了测试。以玻璃析晶峰的形状以及玻璃析晶温度Tx与玻璃转变Tg的差△T为参数,确定了具有较好析晶稳定性的组成区。结果表明:富GeSe2组成区能允许添加更多的CdSe。GeSe2摩尔分数在20%以上时,该三元系统有较大的玻璃形成区,并可对该区域内组成的玻璃进行微晶化处理。红外透射光谱的测试结果表明:所研究的玻璃样品在波长8-12μm区域均具有较好的透过性。

To the Editor:Patients with severe persistent asthma experience greater morbidity with more impairment in quality of life despite higher use of health care resources and being treated with existing asthma treatments such as inhaled corticosteroids and b-agonists,and sometimes oral corticosteroid(OCS)***-2(T2)high asthma has been identified as a phenotype that responds to targeted T2 biologic therapies such as anti-IgE,anti-interleukin(IL)5,or anti-IL5Ra and anti-IL4Ra monoclonal antibodies,which are currently available in Europe and North America,and are currently introduced in the rest of the world.[1]
