200077, Researchers led by Professor Jeongyong Kim at the Department of Energy Science, Sungkyunkwan University, Suwon, Republic of Korea review light-emitting MXene quantum dots. MXenes have found wide-ranging applications in energy storage devices, sensors, catalysis, etc. owing to their high electronic conductivity and wide range of optical absorption. However, the absence of semiconducting MXenes has limited their applications related to light emission. Extensively reviewing current relevant research, the authors summarise recent advances in MXene quantum dot (MQD) research on the synthe...

 E-Mail Input one, output one; input two, output two; input three; output purple --what kind of system is this? Computer algorithms can exist as non-deterministic systems, in which there are multiple possible outcomes for each input. Even if one output is more likely than another, it doesn't necessarily eliminate the possibility of putting in three and getting purple instead of three. Now, a research team from Iowa State University has developed a way to control such systems with more predictability. The results were published in "The supervisory control problem for discrete event systems u...

The internet and wireless connectivity have done that by allowing not only virtually anyone anywhere to connect real time, but by making possible connections between humans and a range of intelligent devices both indoors and outdoors, putting smart cities on the horizon. One key aspect of realizing smart cities is "sma...

 E-Mail Alexandria, Va., USA -- COVID-19 was declared a global pandemic in March 2020 and given an incomplete understanding of the transmission of SARS-CoV-2 at that time, the American Dental Association recommended that dental offices refrain from providing non-emergency services. As a result, 198,000 dentists in the United States closed their doors to patients. The study "Sources of SARS-CoV-2 and Other Microorganisms in Dental Aerosols," published in the Journal of Dental Research (JDR), sought to inform infection-control science by identifying the source of bacteria and viruses in aeros...
