Superaerophobic Polyethyleneimine Hydrogels Improve Electrochemical Hydrogen Manufacturing by Promoting Bubble Detachment

The scheme for a mechanism of bubble-detachment. a) Normal flat electrode, b) the problems of adhered bubbles, and c) various approaches for the removal of gas bubbles. In (a), R, ρ, g, and λ indicate the dimension of bubbles, the density of a solution, gravitational acceleration constant, and surface tension of a solution, respectively....

Strange Phenomenon of Liquid Skin Found on the Surface of Glass

(Guido Mieth/Getty Images) Ice characteristics Ice is not constantly ice all the way through. Even at temperatures level well below freezing, its surface area can be coated in a membrane of quasi-liquid atoms, with its density typically only a few nanometers. Its formation procedure is referred to as premelting (or 'surface melting'), which is why your ice...

Scientists 3D Print Degradable Polymers Utilizing Salt

Texas A&M University researchers are using 3D printing and salt to create environmentally friendly polymers that will degrade over time. Credit: Texas A&M Engineering. Dr. Emily Pentzer, an associate educator in the Division of Materials Science and Engineering and the Division of Chemistry at Texas A&M College, makes 3D printed polymers more environmentally friendly with a...

Novel Polymer Can Improve the Performance of Organic and Perovskite Solar Cells.

Skoltech scientists and their colleagues have synthesized a brand-new conjugated polymer for organic electronic devices through two different chemical reactions and shown the influence of both methods on its efficiency in organic and perovskite solar batteries. The paper was published in the journal Macromolecular Chemistry and Physics. As the world attempts to shift to clean...
