Simulating the formation of ASR gels, solar cells work better with caffeine, and other materials stories that may be of interest for May 1, 2019.
Read MoreSquishy when cold—Graphene foam retains elasticity at cryogenic temperatures
Researchers from Nankai and Rice universities found their 3D cross-linked graphene foam could retain its reversible and robust compressive elasticity at temperatures near absolute zero, a property not observed previously for any other bulk material.
Read MoreVibranium helps educators teach students about chemistry
With the release of “Avengers: Endgame” today, we take the opportunity for some fun and look at how the fictitious metal vibranium can help students learn about the periodic table and transition metal chemistry.
Read MoreDirect-writing additive manufacturing of lead-free piezoelectric parts
As additive manufacturing techniques become increasingly sophisticated, they offer a way to effectively construct specialized electronic devices. Two recent papers describe different direct-writing AM methods for constructing lead-free piezoelectric parts.

Graphene foam is squishy in cold, 3D print chalcogenide glass, and other materials stories that may be of interest for April 24, 2019.
Read MoreRobot uses capacitive sensors in soft hands to separate recyclable materials
Researchers at MIT developed a robot that can effectively separate mixed recyclable materials, using two flexible silicone “hands” to feel the difference between paper, metal, and plastic.
Read MoreMagnetic oxides provide alternative to clean up oil spills
Researchers in Germany developed functionalized iron oxide nanoparticles that can attract hydrocarbons. They are working with industry partners to transfer the concept to real-world oil spill cleanup operations.
Read MoreNo more inert atmospheres—Molten salt synthesis prevents oxidation of materials in air
Nonoxide ceramics typically undergo high-temperature synthesis in an inert atmosphere to prevent spontaneous oxidation. Researchers at Forschungszentrum Jülich have now found that potassium bromide keeps nonoxide ceramics from oxidizing when synthesized in normal air.
