Tao’s group, modified just one of DNA’s iconic double helix chemical letters, abbreviated as A, C, T or G, with another chemical group, called anthraquinone (Aq). Anthraquinone is a three-ringed carbon structure that can be inserted in between DNA base pairs but contains what chemists call a redox group (short for reduction, or gaining electrons

The new perovskite solar cells have achieved an efficiency of 20.1 per cent and can be manufactured at low temperatures, which reduces the cost and expands the number of possible applications.Credit: Kevin Soobrian A U of T Engineering innovation could make printing solar cells as easy and inexpensive as printing a newspaper.

Routing of light in a liquid crystal by a magnetic field (B). The orientation of the field determines the orientation of rod-shaped molecules of the liquid crystal and defines direction of the light trajectory. This trajectory can be rapidly changed by changing the orientation of the magnetic field.Credit: ANU Research led by The Australian National

UChicago researchers achieved levitation of macroscopic objects between warm and cold plates in a vacuum chamber.Credit: Chicago Jean Lachat Although scientists have been able to levitate specific types of material, a pair of UChicago undergraduate physics students helped take the science to a new level. Third-year Frankie Fung and fourth-year Mykhaylo Usatyuk led a team

Researchers have developed a new method of protein ligation, the joining of molecules with proteins. The technique, called Redox Activated Chemical Tagging (ReACT), involves the modification of proteins by attaching chemical cargos to the amino acid methionine. ReACT functions as a new type of chemical Swiss army knife that supports a wide variety of fields,

It has

This is a 3-D printed conductive buckyball that works as an electric switch.Credit: Courtesy of Dinesh K. Patel Due to its excellent material properties of elasticity, resilience, and electrical and thermal insulation, elastomers have been used in a myriad of applications. They are especially ideal for fabricating soft robots, flexible electronics and smart biomedical devices

A schematic illustration of a microbial fuel cell using a paper electrode coated with carbon paste. Credit: Michael Osadciw/University of Rochester The concept behind microbial fuel cells, which rely on bacteria to generate an electrical current, is more than a century old. But turning that concept into a usable tool has been a long process.

The biomimetic tree’s leaves, modeled after cottonwood leaves, rely on piezoelectrical processes to produce electricity.Credit: Christopher Gannon Money doesn’t grow on trees, but electricity might someday. Iowa State University scientists have built a device that mimics the branches and leaves of a cottonwood tree and generates electricity when its artificial leaves sway in the wind.
