It has been previously reported that the tunic of Halocynthia roretzi, mainly composed of cellulose, is actively deformed with mass transfer by the mechanical stimuli. In this study, how the tunic deforms in response to the mechanical environment was investigated.
Scientists at Los Alamos National Laboratory and the US Army Research Laboratory in Aberdeen, Md., have developed a novel 'melt-cast' explosive material that could be a suitable replacement for Trinitrotoluene, more commonly known as TNT.
In a collaborative study involving Equal Channel Angular Extrusion (ECAE), a unique severe plastic deformation (SPD) process, researchers Dr. Ibrahim Karaman from Texas A&M University and Drs. Don Susan and Andrew Kustas of Sandia National Laboratories were able to improve the mechanical properties of magnetic alloys without changing their magnetic properties through microstructural refinement. This process has proven to be troublesome in the past.
High-temperature desalination technologies can efficiently reduce the concentrations of a chemical element in seawater to make it an effective substitute for fresh water. Research that has investigated how the element boron evaporates could help produce higher-quality drinking and irrigation water.
Two chemistry researchers at The University of Texas at San Antonio (UTSA) have developed a method that can show quickly and accurately whether a person has been infected with harmful bacteria or other pathogens. Additionally, this new method shows the exact severity of infection in a person.
Engineering Assistant Professor Andrew K. Dickerson and graduate student Nicholas M. Smith have figured out the mechanics of how oranges release that thin stream of fragrant oil when squeezed. They characterized the orange peels' structure and figured out the role the layers have to create the microjet dynamic. By mimicking nature's mechanism of an orange layer, pharmaceutical companies may be able to develop a less expensive and less complex way to deliver airborne medication.
Flight schedules that allow for a little carefully designed wiggle room could prevent the frustration of cascading airport delays and cancellations. By focusing on the early phases of flight schedule planning and delays at various scales, researchers have developed models to help create schedules that are less susceptible to delays and easier to fix once disrupted.
Scientists at Tokyo Tech have designed and fabricated a tiny, but incredibly fast, reliable, and accurate 28-GHz transceiver meant for stable high-speed 5G communications. The fabricated transceiver trumps previous designs in various regards by taking a new approach for beam steering.
In Neuchâtel, Switzerland, researchers from EPFL and CSEM have combined silicon- and perovskite-based solar cells. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent.
Researchers at Nagoya University used bacteria to convert benzene into phenol. They developed 'decoy' molecules -- modified amino acids -- mimicking the native substrates of a genetically expressed oxygenase enzyme. When absorbed by live E.coli cells, the decoys were misrecognized as substrates of the oxygenase, which became activated. The bacteria then oxidized a supplied benzene source, needing only glucose as fuel.
