    NIR LED perovskite LED LED research

    An international research team has developed near-infrared (NIR) LED based on perovskite in a laboratory at Linköping University in Sweden which achieve a record external quantum efficiency of 21.6 percent

     

    Perovskites have good light-emitting properties and are easy to manufacture. However, the external quantum efficiency of perovskite-based LED has until now been limited due to defects that arise in the material during manufacture. The defects act as traps for the charge carriers and thus cause energy losses.

    China CDC publishes multilingual epidemic control manuals for COVID-19

    To allow timely sharing with other countries of the most up-to-date COVID-19 control and prevention information, particularly as developing countries often have weaker healthcare systems and resources, a critical multilingual manual has been published in both English and French by the Chinese Center for Disease Control and Prevention. To comprehensively disseminate education on control and prevention of COVID-19 globally, based on the latest authoritative materials from China CDC, the World Health Organization and related periodicals -- with first-hand information from China, China CDC has organized experts and translators to develop the set of color publicity manuals containing FAQs regarding control and prevention of the epidemic(www.chinacdc.cn/en/COVID19). The compilation consists of such chapters as General Questions, Maternal and Child Health, Personal and Other Types of Protection, Diagnosis and Treatment. The manual, in a Q&A format, clarifies principal concerns of the general public in a systematic and focused manner, and has different color sketches tailored to African, ASEAN and South Asian countries, and is applicable for use by medical professionals and the general public alike. It can also be downloaded from the website to be circulated, or printed for distribution by Chinese embassies and consulates abroad, public health institutions of countries in Africa and other continents, foreign counterparts and the general public. At the same time, the manuals can also serve as materials to be used by Chinese experts when they go abroad for exchanges and training programs.

    The Colour Of Light: Spectrally Optimised Light From BÄRO

    Light creates an atmosphere – and it supports the attractive presentation of all kinds of objects and products. From fresh foodstuffs or dishes in a restaurant, non-food products, fashion and leisure articles – lighting with a coordinated spectral composition can render the colour, material and surface properties of products in a way that shows them off to best advantage to customers and users. Successful sales-promoting lighting therefore deliberately engages with expectations and visual habits – and triggers positive associations.
