Complications for Clean Energy Storage and Transportation Created by Hydrogen Embrittlement
As the global energy market shifts from coal, petroleum fuel, and natural gas to more environmentally friendly primary energy sources, hydrogen is becoming a crucial pillar in the clean energy movement. Developing safe and cost-effective storage and transportation methods for hydrogen is essential but complicated given the interaction of hydrogen with structural materials. […]

Fabric-Based Piezoelectric Energy Harvester Relies on Hot Pressing and Tape Casting
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have presented a study that describes a highly flexible and sturdy wearable piezoelectric harvester that uses a simple fabrication process involving hot pressing and tape casting. […]

In-situ development of a sandwich microstructure with enhanced ductility by laser reheating of a laser melted titanium alloy
Metallic additive manufacturing, particularly selective laser melting (SLM), usually involves rapid heating and cooling and steep thermal gradients within melt pools, making it extremely difficult to achieve effective control over microstructure. In this study, we propose a new in-situ approach which involves laser reheating/re-melting of SLM-processed layers to engineer metallic materials. […]
SpaceX Starlink Mission Launch
On Tuesday, October 6 at 7:29 a.m. EDT, 11:29 UTC, SpaceX launched 60 Starlink satellites from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. Falcon 9’s first stage previously supported launch of Crew Dragon’s first flight to the International Space Station with NASA astronauts onboard and the ANASIS-II mission. Following stage separation, SpaceX landed Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which was stationed in the Atlantic Ocean. […]

Anticipating heart failure with machine learning
Every year, roughly one out of eight U.S. deaths is caused at least in part by heart failure. One of acute heart failure’s most common warning signs is excess fluid in the lungs, a condition known as “pulmonary edema.”
A patient’s exact level of excess fluid often dictates the doctor’s course of action, but making such determinations is difficult and requires clinicians to rely on subtle features in X-rays that sometimes lead to inconsistent diagnoses and treatment plans. […]
