With millions of tons of human waste we could make mountains of graphene microchips :3.
A trio of researchers, two from the University of Chemistry and Technology, Praha 6, the other the University of Toronto, has demonstrated that chicken feces can be used to make graphene a better catalyst. In their paper published in the journal ACS Nano, Lu Wang, Zdenek Sofer and Martin Pumera argue that researchers churning out papers describing newly found dopants for graphene are not contributing to understanding graphene’s electrocatalytic abilities.
Graphene has been found to have conductivity and strength characteristics that make it a desirable material for use in commercial products. Some have suggested it might also make an excellent catalyst if the right dopant can be found. To that end, researchers have been testing various materials as dopants for graphene to find new ways to use graphene. In their paper, Pumera et al. argue that rather than simply testing materials one after another with graphene, researchers might make better use of their time by devising experiments designed to better understand the fundamentals of graphene’s electrocatalytic abilities. To drive their point home, they wondered if any “crap” they tested would work as a possible dopant—to find out, they tested chicken crap. They prepared samples of graphene oxide using two different methods, then combined each with chicken feces—they then used thermal exfoliation on the results to make graphene.

Astronomers may have detected a dozen large objects lurking beyond the Kuiper Belt at the edge of our solar system, suggesting there could be another equally massive, “second Kuiper Belt” hiding beyond the orbit of Pluto.
Remote control of chemical reactions in biological environments could enable a diverse range of medical applications. The ability to release chemotherapy drugs on target in the body, for example, could help bypass the damaging side effects associated with these toxic compounds. With this aim, researchers at California Institute of Technology (Caltech) have created an entirely new drug-delivery system that uses ultrasound to release diagnostic or therapeutic compounds precisely when and where they are needed.
The platform, developed in the labs of Maxwell Robb and Mikhail Shapiro, is based around force-sensitive molecules known as mechanophores that undergo chemical changes when subjected to physical force and release smaller cargo molecules. The mechanical stimulus can be provided via focused ultrasound (FUS), which penetrates deep into biological tissues and can be applied with submillimetre precision. Earlier studies on this method, however, required high acoustic intensities that cause heating and could damage nearby tissue.
To enable the use of lower – and safer – ultrasound intensities, the researchers turned to gas vesicles (GVs), air-filled protein nanostructures that can be used as ultrasound contrast agents. They hypothesized that the GVs could function as acousto-mechanical transducers to focus the ultrasound energy: when exposed to FUS, the GVs undergo cavitation with the resulting energy activating the mechanophore.
