Ranga Dias, the physicist who claims to have discovered the first room-temperature superconductor, was found to have engaged in “research misconduct,” The Wall Street Journal reports.
A team of researchers claims to have created the first materials that conduct electricity perfectly at room temperature and ambient pressure, but many physicists are highly sceptical. Superconductors are materials through which electricity can move without encountering any resistance, and so would significa...
thus preventing or minimizing the risk of contamination of other areas and possible cross-contamination. In some cases, it may be advisable to have airlocks or pass through hatches between rooms or areas. In addition, sufficient dilution, pressure differentials (recommended minimum...

Transfer the fluid to a microscope slide, and allow the sample to dry at room temperature. To identify the estrous cycle stage the female is in, the types of cells present (cornified epithelial, nucleated epithelial, and leukocytes) and ratio of these cells is determined by crystal violet ...

The article exams the possibility of reducing the air purification time from finely dispersed PM2.5 particles to meet with WHO recommendations in an office space at a standard temperature and humidity. A recirculation unit equipped with a HEPA11 filter was chosen. The time taken by the recirculatio...
It was possible to achieve a level of reduction in PM2.5 for the given volume of the room by 97 % from the initial level of pollution. Increasing the frequency of air changes from two to almost six times made it possible to speed up the cleaning process. This reduced the time a person...
control of temperature in the system by heat exchangers or plantroom cooling in order to reduce the risk of microbial growth (guidance value< 25 °C); 通过热交换器或工厂房间冷却来控制系统内的温度,以减少微生物生长的风险(指导值<25℃); ...
working within the very latest international codes of practice. It is recognised as an innovator, having contributed significantly to modern cleanroom garment design and management techniques. All Micronclean centres operate from modern premises and with a workforce committed to a ‘right first time’ ...
