Theory for one type of superconductor solves puzzle in another

11-May-2018

A 2017 theory proposed by Rice University physicists to explain the contradictory behavior of an iron-based high-temperature superconductor is helping solve a puzzle in a different type of unconventional superconductor, the "heavy fermion" compound known as CeCu2Si2. An international team from ...

Salt boosts creation of 2-D materials

23-Apr-2018

A dash of salt can simplify the creation of two-dimensional materials, and thanks to Rice University scientists, the reason is becoming clear. Boris Yakobson, a Rice professor of materials science and nanoengineering and of chemistry, was the go-to expert when a group of labs in Singapore, China, ...

Mechanism of oxidative unzipping of multiwall carbon nanotubes to graphene nanoribbons

13-Apr-2018

Graphene, a two-dimensional lattice of carbon atoms, has attracted enormous interest from a broad base of the research community for more than one decade. Graphene nanoribbons (GNRs), narrow strips of graphene, being quasi one-dimensional, possess complementary features relative to their ...

For graphite pellets, just add elbow grease

26-Mar-2018

It's easy and economical to make shiny pellets of graphite from functionalized graphene, according to scientists at Rice University. A report shows how chemically altered graphene powder can be pressed into a lightweight, semiporous solid that retains many of the strong and conductive qualities ...

Fast-spinning spheres show nanoscale systems' secrets

09-Feb-2018

Spin a merry-go-round fast enough and the riders fly off in all directions. But the spinning particles in a Rice University lab do just the opposite. Experiments in the Rice lab of chemical engineer Sibani Lisa Biswal show micron-sized spheres coming together under the influence of a rapidly ...

Weak hydrogen bonds key to strong, tough infrastructure

31-Jan-2018

The right mix of hydrogen bonds in polymer and cement composites is critical to making strong, tough and ductile infrastructure material, according to Rice University scientists who want to mimic the mechanics of mother-of-pearl and similar natural composites with synthetic materials. Seashells ...
