this study aimed to develop an index that can rank welding workplace that associate well with possible health risk of welders.welding fumes health index (wfhi) were developed based on data from case studies conducted in plant 1 and plant 2. personal sampling of welding fumes to assess the concentration of metal constituents along with series of lung function tests was conducted. fifteen metal c...

The success of printing technology in the electronics industry primarily depends on the availability of metal printing ink. Various types of commercially available metal ink are widely used in different industries such as the solar cell, radio frequency identification (RFID) and light emitting diode (LED) industries, with limited usage in semiconductor packaging. The use of printed ink in semic...

Silicon, the main constituent of microprocessor chips, is emerging as a promising material for the realization of future quantum processors. Leveraging its well-established complementary metal-oxide-semiconductor (CMOS) technology would be a clear asset to the development of scalable quantum computing architectures and to their co-integration with classical control hardware. Here we report a si...
