Researchers develop 3D-printed shape memory alloy with superior superelasticity

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive for applications in the biomedical and aerospace fields, it has rarely showcased the superelasticity required for specific applications using nickel-titanium...

More states want power to approve wetlands development

In 2020, Florida became just the third state—and the first in decades—to take over management of a key federal Clean Water Act program. Now, state rather than federal officials decide whether companies can dredge and fill wetlands and waterways for projects ranging from mining to housing developments to roads and bridges.

'Growing end' of inflammation discovered

Redness, swelling, pain -- these are signs of inflammation. It serves to protect the body from pathogens or foreign substances. Researchers were able to show that inflammatory reactions of an important sensor protein proceed in a specific spatial direction. This finding has the potential to conceivably stop inflammation at the 'growing end', and thus bring chronic inflammatory diseases to a halt.

Development of a novel large-scale manufacturing technology for sulfide solid electrolytes

A research group in the doctoral program of Toyohashi University of Technology's Department of Electrical and Electronic Information Engineering that includes a doctoral student Hirotada Gamo and specially appointed assistant professor Jin Nishida, specially appointed associate professor Atsushi Nagai, assistant professor Kazuhiro Hikima, professor Atsunori Matsuda and others, developed a...

New aircraft structures production technology has increased their strength

Scientists from NUST MISIS have developed a method of producing composite parts for the aerospace industry, which has increased the strength of finished products by 15% due to a combination of laser technologies and isostatic pressing. The results of the study have been published in The International Journal of Advanced Manufacturing Technology.

Seasonal variations of methane consuming and methane producing microbial communities contribute to emissions

Wetland ecosystems are the most important and prolific natural methane (CH4) sources. CH4 is constantly flowing in and out of these regions (flux), and that flow periodically fluctuates. Methanogens (methane producers) and methanotrophs (methane consumers) are microorganisms that influence CH4 fluxes in wetlands. However, the mutual, or symbiotic relationship between methanogens and methanotrophs...

Going gentle on mechanical quantum systems

Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum properties of such systems can be measured without destroying the quantum state -- a key ingredient for tapping the full potential of mechanical quantum systems.

Malaria parasites form vortices

Researchers managed to set larger groups of malaria parasites into motion and to analyze the acquired image data. The collectively moving pathogens form vortex systems that are largely determined by physical principles. Computer simulations helped identify the mechanisms underlying these rotating movements.

Going gentle on mechanical quantum systems

When thinking about quantum mechanical systems, single photons and well-isolated ions and atoms may spring to mind, or electrons spreading through a crystal. More exotic in the context of quantum mechanics are genuinely mechanical quantum systems; that is, massive objects in which mechanical motion such as vibration is quantized. In a series of seminal experiments, quintessential...
