Gel-like fluid designed to prevent wildfires

Scientists and engineers worked with state and local agencies to develop and test a long-lasting, environmentally benign fire-retarding material. If used on high-risk areas, the simple, affordable treatment could dramatically cut the number of fires that occur each year.

Tetravinylallene, a small but powerful molecule, synthesized for first time

Many natural compounds used in medicine have complex molecular architectures that are difficult to recreate in the lab. Help could come from a small hydrocarbon molecule, called tetravinylallene, which has been synthesized for the first time by scientists. Tetravinylallene can be used to construct complex molecular frameworks more quickly and with less environmental impact than by using established methods.

New design of bioactive peptide nanofibers keeping both temperature reversibility and stiffness control

Scientists have developed a new method of molecular design to control both temperature reversibility and stiffness of nanofibers that are gel-forming peptides. The peptide nanofiber hydrogel can be used as biomedical materials. This method will allow the peptide nanofibers more biomedical applicable.

Scientists finally find superconductivity in place they have been looking for decades

Scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern – as if hopping to the atom diagonally across the street rather than to the one next door.

Machine learning finds new metamaterial designs for energy harvesting

Electrical engineers have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The technique drops the time needed to simulate possible configurations from more than 2,000 years to 23 hours, which should facilitate the design of sustainable types of thermal energy harvesters and lighting.
