RoboEthics in COVID-19: A Case Study in Dentistry.

The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures.

Application of DenTeach in Remote Dentistry Teaching and Learning During the COVID-19 Pandemic: A Case Study.

In December 2019, an outbreak of novel coronavirus pneumonia occurred, and subsequently attracted worldwide attention when it bloomed into the COVID-19 pandemic. To limit the spread and transmission of the novel coronavirus, governments, regulatory bodies, and health authorities across the globe strongly enforced shut down of educational institutions including medical and dental schools. The adverse effects of COVID-19 on dental education have been tremendous, including difficulties in the delivery of practical courses such as restorative dentistry.

A structural study of 2,4-di-methyl-aniline derivatives.

Crystallographic studies of nitro-gen-containing small mol-ecules aid in the elucidation of their structure-activity relationships and modes of aggregation. In this study, two previously synthesized mol-ecules are crystallographically characterized for the first time. Reaction of 2,4-di-methyl-aniline with -bromo-succinimide affords the -brominated derivative 2-bromo-4,6-di-methyl-aniline (; CHBrN), which sublimates to afford crystals featuring hydrogen-bonded chains as well as Type I halogen-halogen inter-actions.
