Hydrogen has been hailed as the fuel of the future owing to several reasons. First, compared to the conventionally used hydrocarbons, hydrogen exhibits higher energy yield. Second, the commercial use of hydrogen fuel, which yields only water as a byproduct product, would help mitigate the imminent global warming crisis by reducing the use of exhaustible and polluting fossil fuels. Thus, ongoing research has been focusing on efficient and environment-friendly ways to produce of hydrogen fuel.

A lot of our medicines and other bioactive drugs are based on chemical structures called enantiomers molecules that are mirror images of each other and are non-superimposable. Notable among them are chiral N,N-acetals contained in diuretic drugs like bendroflumethiazide and thiabutazide, used to treat high blood pressure and edema. Because an enantiomer and its mirror image version often have different biological activities, with only one of them having pharmacological utility, an enantioselective or asymmetric synthesis yielding the desired enantiomer in greater amounts is highly desirable.

Silicon carbide (SiC), a versatile and resistant material that exists in multiple crystalline forms, has attracted much attention thanks to its unique electronic properties. From its use in the first LED devices, to its applications in high-voltage devices with low power losses, SiC displays exceptional semiconductor behavior. So far, the operating voltages for unipolar SiC devices are below 3.3 kV. Though useful for the electronic systems of cars, trains, and home appliances, unipolar SiC-based devices cannot be used in power generation and distribution systems, which operate at voltages above 10 kV.
