A scalable photoelectrochemical system for green hydrogen production

Posted by in categories: chemistry, engineering, solar power, sustainability

If realized using solar energy or other renewable energy, water splitting could be a promising way of sustainably producing hydrogen (H2) on a large-scale. Most photoelectrochemical water splitting systems proposed so far, however, have been found to be either inefficient, unstable, or difficult to implement on a large-scale.

Researchers at Ulsan National Institute of Science and Technology (UNIST) recently set out to develop a scalable and efficient photoelectrochemical (PEC) system to produce green hydrogen. Their proposed system, outlined in Nature Energy, is based on an innovative formamidinium lead triiodide (FAPbI3) perovskite-based photoanode, encapsulated by an Ni foil/NiFeOOH electrocatalyst.

“Our group has thoroughly studied the challenges associated with practical solar hydrogen production,” Jae Sung Lee, Professor of Energy & Chemical Engineering at UNIST and co-author of the paper, told Tech Xplore. “As summarized in our most recent review paper, minimum 10% of solar-to-hydrogen (STH) efficiency is required to develop viable practical PEC system, for which selecting an efficient material is the first criteria.”

Researchers discover one million new components of the human genome

Posted by in category: biotech/medical

Researchers at the University of Toronto’s Donnelly Center for Cellular and Biomolecular Research have found nearly one million new exons—stretches of DNA that are expressed in mature RNA—in the human genome.

The findings were published in the journal Genome Research.

There are around 20,000 in humans that contain approximately 180,000 known internal exons. These protein-coding regions account for only one percent of the entire . The vast majority of what remains is a mystery—aptly referred to as the “dark genome.”

Understanding Limerence: Letting Go & Building Real Connections

Posted by in category: habitats

Limerence is a state of mind that prevents genuine connections by prioritizing an idealized fantasy relationship over reality, and letting go of limerence requires taking responsibility, understanding fantasies, and finding real connections.

Questions to inspire discussion.
