The saline-rich and humid environment of the ocean and coast is hazardous to building materials, causing them to corrode and break down over time. As waters rise, coastal structures are put at more risk against the aggressive elements of their oceanic home.

Porosity has the greatest single effect on the response of PM Steels to heat treatment compared with conventional steels. The majority of parts have a porosity between 5 and 15 vol%, far more than is found in a typical casting. Every mechanism in press and sinter is subject to diminishing returns; i.e., compact density has a decreasing dependence on compaction pressure, as does sintering and homogenization.

Imagine a metal, scaffold-shaped implant that could support the regrowth of a shattered bone. All that would be needed would be an initial CT scan, a virtual construction of the implant, and a metal printer to produce the final product. Devastating outcomes like amputation or loss of the ability to walk could be prevented.

A team of scientists has proposed a new type of metamaterial that could create backward waves when transmitting sound. They published their design in the journal Nature Communications in June 2021. The team behind the new addition to the metamaterial portfolio was inspired by superfluid helium-4: a liquid form of helium with no viscosity that can only be observed at an extremely low temperature of around minus 450 degrees Fahrenheit.

A new paper in Science Advances, provides a blueprint for designing multifunctional materials using different combinations of nanocrystals. By bringing together theory, computational simulations, chemical synthesis, and assembly, researchers from the University of Pennsylvania and the University of Michigan demonstrate how an “inverse design” strategy can create unique materials from nanocrystals of varying compositions, sizes, and shapes.

During sintering, metallurgical bonds form between powder particles. Strength, ductility, toughness, and electrical and thermal conductivities increase with increasing density. If different materials were blended together, interdiffusion could promote the formation of alloys and intermetallic phases. As a consequence of the density increases, size decreases.

Tungsten has many excellent properties. It resists corrosion, and its melting point of 3422°C is the highest of all metals, making it an ideal material for components that operate at extreme temperatures. There is a problem, though: it is highly brittle at room temperature, which means it is hard to process using conventional techniques.

Nature produces a startling array of patterned materials, from the sensitive ridges on a person’s fingertip to a cheetah’s camouflaging spots. Although nature’s patterns arise spontaneously during development, creating patterns on synthetic materials is more laborious. Now, researchers reporting in ACS Central Science have found an easy way to make patterned materials having complex microstructures with variations in mechanical, thermal, and optical properties — without the need for masks, molds, or printers.
