Catholic chaplains minister to families at Arlington National Cemetery Posted
Father Eduardo B. Amora, a Navy chaplain who holds the rank of lieutenant commander, gives remarks Sept. 27, 2018, at Arlington National Cemetery during the group burial of four Marines and one sailor who died during the Vietnam War. Buried in Section 60 of the cemetery, their remains were identified decades after their deaths by the Defense POW/MIA Accounting Agency. Father Amora is a priest of the Diocese of Mati, Philippines, on assignment with the U.S. Archdiocese for the Military Services.

Twisting Atomically Thin Semiconductor Materials may Convert Light into Electricity
Written by AZoOpticsMay 3 2021
A pair of physicists at the University of California, Riverside, are aiming to convert light falling on atomically thin semiconductor materials into electricity, having received more than $582,000 in funding from the U.S. Department of the Army.
Nathaniel Gabor and Vivek Aji, both associate professors of physics and astronomy, will focus on how the fundamental science of light and its interaction with matter enables new sensing capabilities in layered and twisted vertical structures of stacked monolayer semiconductors. The researchers aim to understand how electronic excitations influence the flow of photo-absorbed energy in ultrasmall semiconducting optoelectronic materials.

Scientists harness chaos to protect devices from hackers
Researchers have found a way to use chaos to help develop digital fingerprints for electronic devices that may be unique enough to foil even the most sophisticated hackers.
Just how unique are these fingerprints? The researchers believe it would take longer than the lifetime of the universe to test for every possible combination available.
“In our system, chaos is very, very good,” said Daniel Gauthier, senior author of the study and professor of physics at The Ohio State University.
The study was recently published online in the journal IEEE Access.
