Wayne State University professor receives NSF grant to study quantum tunneling

Aims to discover whether tunneling is instantaneous and if new detector technologies can be developed

2024-08-05
(Press-News.org) DETROIT — A Wayne State University professor recently received a three-year, $626,467 grant from the National Science Foundation’s Division of Physics. The project, “Probing Nonadiabatic Strong Field Ionization with Phase-Resolved Attoclock,” will research a quantum mechanical process known as quantum tunneling.

Wen Li, Ph.D., professor of chemistry in Wayne State’s College of Liberal Arts and Sciences and his research team propose a new technique they have developed to study the process of quantum tunneling, a quantum mechanical phenomenon in which an object such as an electron or atom passes through a potential energy barrier that, according to classical mechanics, should not be passable due to the object not having sufficient energy to pass or surmount the barrier.

“What’s not known about quantum tunneling is the behavior of the particles during the tunneling process,” said Li. “When you pull electrons through a barrier created by the nucleus with an intense laser field, it is unknown what happens within the barrier. This particle essentially goes through a wall as though there was no wall there and we don’t know how. We want to study what that electron does within that barrier.”

Quantum tunneling is a fundamental process that underpins many important physical phenomena and technologies, such as nuclear fusion and chemical reactions essential for life. Li aims to answer the critical question of whether tunneling is instantaneous and will investigate whether new detector technologies can be developed.

“Other than study the general behavior of particles, we want to understand the process to improve attosecond pulse production,” said Li. “This is important for developing a fast camera that takes 10 to the power of 16 frames per second to measure fast electron processes, such as those seen during a chemical reaction. We need something that fast to observe these processes. If you understand electrons, you can understand chemical reactions. If you understand chemical reactions, you can understand biology. That means that the eventual applications of this research could be enormous.”

“This research has the potential to have a far-reaching impact in a wide range of fields, including medicine, business and beyond,” said Ezemenari M. Obasi, Ph.D., vice president for research & innovation at Wayne State University. “I look forward to seeing the important outcomes of Dr. Li’s research team.”

The award number for this National Science Foundation grant is 2409529.

August 4, 2024-- Drug-involved overdose deaths increased by over 500 percent in 2022 according to a study at Columbia University Mailman School of Public Health, with trends attributed to synthetic opioids. National data shows that fentanyl and heroin in particular attributed substantially to the rise particularly since 2014. However, the study also reports that income protection policies, can have a supportive role in preventing fatal drug overdoses. The findings are reported in the International ...

Could this new drug turn back the clock on multiple sclerosis?

2024-08-05
Could This New Drug Turn Back the Clock on Multiple Sclerosis? Ten years of work, and a little help from the green mamba snake, has resulted in a promising new drug that is already being tested in clinical trials. Multiple sclerosis (MS) degrades the protective insulation around nerve cells, leaving their axons, which carry electrical impulses, exposed like bare wires. This can cause devastating problems with movement, balance and vision; and without treatment, it can lead to paralysis, loss of independence and a shortened lifespan. Now, scientists at UC San Francisco and Contineum Therapeutics have developed a drug that spurs the body to replace the lost insulation, ...

Greenland fossil discovery reveals increased risk of sea-level catastrophe

Greenland fossil discovery reveals increased risk of sea-level catastrophe
2024-08-05
The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland’s ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape. A team of scientists re-examined a few inches of sediment from the bottom of a two-mile-deep ice core extracted at the very center of Greenland in 1993—and held for 30 years in a Colorado storage facility. They were amazed to discover ...

2024-08-05
Northwestern University scientists have developed a new bioactive material that successfully regenerated high-quality cartilage in the knee joints of a large-animal model. Although it looks like a rubbery goo, the material is actually a complex network of molecular components, which work together to mimic cartilage’s natural environment in the body.  In the new study, the researchers applied the material to damaged cartilage in the animals’ knee joints. Within just six months, the researchers observed evidence of enhanced repair, including ...

Horse miscarriages offer clues to causes of early human pregnancy loss

2024-08-05
ITHACA, N.Y. – A study of horses – which share many important similarities with humans in their chromosomes and pregnancies – revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra set of chromosomes, a condition called triploidy. “Over that embryonic period  [up to eight weeks from conception], triploidy had rarely been reported in mammals outside of women,” said Mandi de Mestre, professor of equine medicine at Cornell University. “The study tells us that over the first six weeks ...

Hydraulic lift technology may have helped build Egypt’s iconic Pyramid of Djoser
2024-08-05
The Pyramid of Djoser, the oldest of Egypt’s iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to a study published August 5, 2024, in the open-access journal PLOS ONE by Xavier Landreau from CEA Paleotechnic Institute, France, and colleagues. The new study suggests that water may have been able to flow into two shafts located inside the pyramid itself, where that water could have been used to help raise and lower a float used to carry the building stones. The Pyramid of Djoser, also known as the Step Pyramid, is believed ...

Tradition meets transformation for Maasai women

Tradition meets transformation for Maasai women
2024-08-05
Few communities reveal both the challenges and opportunities presented by cultural globalism more than Maasai communities in northern Tanzania. Traditionally pastoralists, the Maasai ethnic group’s social structure is historically patriarchal, with a man’s prestige measured by the size of his family and by the livestock he owns. The shrinking world has brought change: Urban centers and the promise of jobs are luring young Maasai from communities, and new technologies such as mobile phones are shifting social patterns and structures that ...
