Reactions at the interface between water and other phases play important roles in various chemical settings. Now, ultrafast phase-sensitive interface-selective vibrational spectroscopy has revealed that the photoionization of phenol can occur four orders of magnitude faster at the water surface than in the bulk aqueous phase.
August 2020… “As Covid-19 continues to take lives on a daily basis, the search is ongoing for solutions that might prevent, cure or treat the deadly disease. In recent months, some have pointed to cannabis as a possible treatment for severe cases of the Covid-19 — pointing specifically towards the cannabinoid CBD, one of cannabis’ main chemical ingredients. And some research has suggested that this cannabinoid could be helpful. Now, a synthetic cannabinoid drug, ARDS-003, has been given approval by the FDA to begin phase-1 clinical trials. ARDS-003 is an injectable drug designed to help with acute respiratory distress syndrome (ARDS), a serious syndrome that occurs in severe cases of the novel coronavirus. This syndrome can be triggered during a cytokine storm, a dangerous over-elevation of cytokines. Cytokines are proteins which signal the body to produce more inflammation. While inflammation is a normal and healthy part of immune responses, when too much of it is produced, it can lead to serious and deadly problems like organ failure and ARDS. ”.
In the past few years, researchers have turned increasingly to data science techniques to aid problem-solving in organic synthesis.
The U.S. military routinely deploys throughout the world where warfighters can potentially be exposed to regional endemic diseases as well as chemical, biological, radiological, or nuclear (CBRN) threats. Rapid access to medical countermeasures (MCMs) against these threats is critical to protect Defense Department (DoD) personnel and local populations; however, manufacturing, stockpiling, and distribution issues remain.
That’s not to say Taiwan is the only player in the semiconductor supply chain. The U.S. still holds dominant positions, notably in chip design and electronic software tools; ASML Holding NV of the Netherlands has a monopoly on the machines needed to fabricate the best chips; Japan is a key supplier of equipment, chemicals and wafers.
U.S., European and Japanese automakers are lobbying their governments for help, with Taiwan and TSMC being asked to step in. Chancellor Angela Merkel and President Emmanuel Macron discussed the potential for shortages last year and agreed on the need to accelerate Europe’s push to develop its own chip industry, according to a French official with knowledge of the matter.
The auto industry’s pleas illustrate how TSMC’s chip-making skills have handed Taiwan political and economic leverage in a world where technology is being enlisted in the great power rivalry between the U.S. and China — a standoff unlikely to ease under the administration of Joe Biden.

Hyosung Chairman Hyun-Joon Cho has begun to activate the hydrogen economy by preparing to construct the world’s largest liquid hydrogen factory following a large-scale investment in carbon fiber last year.
Hyosung joined hands with the Linde Group, a global chemical company specializing in industrial gas, to establish a value chain encompassing the production and transportation of liquid hydrogen and installation and operation of charging stations by investing KRW 300 billion in all by 2022. For this purpose, an MOU was signed by Hyosung Chairman Hyun-Joon Cho and Linde Korea Chairman Baek-Seok Seong on April 28 at the head office of Hyosung in Mapo, Seoul.

The many different sensations our bodies experience are accompanied by deeply complex exchanges of information within the brain, and the feeling of pain is no exception. So far, research has shown how pain intensity can be directly related to specific patterns of oscillation in brain activity, which are altered by the activation and deactivation of the ‘interneurons’ connecting different regions of the brain. However, it remains unclear how the process is affected by ‘inhibitory’ interneurons, which prevent chemical messages from passing between these regions. Through new research published in EPJ B, researchers led by Fernando Montani at Instituto de Física La Plata, Argentina, show that inhibitory interneurons make up 20% of the circuitry in the brain required for pain processing.
Biochemical changes after going to space suggest that harm to cells’ energy-producing structures, called mitochondria, could explain astronauts’ health issues.
Scientists have finally uncovered some of the basic chemical properties of einsteinium — one of the hardest elements to study.
The researchers conducted a series of government-funded surveys from 2011 to 2020 and located potentially high-yield deposits of various essential industrial minerals from nickel to rare earths, according to a paper published in the Chinese-language Bulletin of Mineralogy, Petrology and Geochemistry last week.
Chinese researchers have spent the last decade mapping the globe’s ocean floors looking for potential mineral deposits.
