Manganese gets its moment as a potential fuel cell catalyst
The road to a more sustainable planet may be partially paved with manganese. According to a new study by researchers at Yale and the University of Missouri, chemical catalysts containing manganese—an abundant, inexpensive metallic element—proved highly effective in converting carbon dioxide into formate, a compound viewed as a potential key contributor of hydrogen for the next generation of fuel cells.
The new study appears in the journal Chem. The lead authors are Yale postdoctoral researcher Justin Wedal and Missouri graduate research assistant Kyler Virtue; the senior authors are professors Nilay Hazari of Yale and Wesley Bernskoetter of Missouri.
Sunlight-driven nanoparticles enable cleaner ammonia synthesis at room temperature
Ammonia (NH3) is a colorless chemical compound comprised of nitrogen and hydrogen that is widely used in agriculture and in industrial settings. Among other things, it is used to produce fertilizers, as well as cleaning products and explosives.
Currently, ammonia is primarily produced via the so-called Haber-Bosch process, an industrial technique that entails prompting a reaction between nitrogen and hydrogen at very high temperatures and pressure. Despite its widespread use, this process is known to be highly energy-intensive and is estimated to be responsible for approximately 3% of global greenhouse gas emissions.
Researchers at Stanford University School of Engineering, Boston College and other institutes have identified new promising catalysts (i.e., materials that speed up chemical reactions) that could enable the sunlight-driven synthesis of ammonia at room temperature and under normal atmospheric pressure.
Sulfate and carbon in fine air pollution tied to higher depression risk
Long-term exposure to fine particulate matter like PM2.5 components in polluted air can not only cause respiratory diseases, but also increase the risk of depression in older people, especially in those living with preexisting heart, metabolic and neurological conditions.
Depression has caused more loss of healthy life worldwide than any other mental health condition. This disorder has snatched away people’s will to perform the basics of daily activities. An analysis of global health data in 2021 showed that all the years people lived with disability or reduced quality of life because of depression added up to about 56.3 million years.
A recent population-based cohort study collected data from nearly 23.7 million U.S. Medicare beneficiaries aged 65 years and older between 2000 and 2018 to examine specific components of PM2.5 exposure, both individually and in combination, and its associations with the risk of developing depression. Among those tracked, more than 5.5 million developed depression during the follow-up period. These findings are published in JAMA Network Open.
Why Aliens Will Probably Be AI Robots
#aliens #uap #ufos.
Is there other life out there in the universe? Do aliens really exist? If so, then where are they all?! In this most epic of episodes, Dom has his favourite film (Aliens) interrupted by an extraterrestrial visitor — how very inconsiderate! As he prepares his arsenal to avoid alien abduction, he investigates the odds of life being out there in the galaxy, why we haven’t found it yet and what it might look like if we ever do.
A huge thanks to Vlogbrothers for their sponsorship of this video.

New calibration module offers improved measurement of thermoelectric device performance
A standard reference thermoelectric module (SRTEM) for objectively measuring thermoelectric module performance has been developed in Korea for the first time. A research team led by Dr. Sang Hyun Park at the Korea Institute of Energy Research developed the world’s second standard reference thermoelectric module, following Japan, and improved its performance by more than 20% compared with existing modules, demonstrating the excellence of Korea’s homegrown technology. The findings are published in the journal ACS Applied Materials & Interfaces.
A thermoelectric module is a device that generates electricity by creating a flow of electrons driven by a temperature difference, with one side becoming cold and the other becoming hot. Conversely, when an electric current is applied to a thermoelectric module, one side cools down while the other side heats up.
Thanks to these characteristics, thermoelectric modules are widely used in applications such as compact camping refrigerators and electronic equipment including computers. In addition, because they are environmentally friendly and well suited to miniaturization, they can be broadly applied to emerging fields such as carbon-free power generation and the space industry, which have recently drawn significant attention.
