A new database contains the results of exposure experiments on solar reflectors conducted over more than four decades. The publicly available Solar Mirror Materials Database (SMMD) will contain information from thousands of solar mirror samples from more than a hundred suppliers that have been subjected to outdoor tests and laboratory environments.

Formic acid, which can be produced electrochemically from carbon dioxide, is a promising energy carrier. A research team has now developed a fast-charging hybrid battery system that combines the electrochemical generation of formic acid as an energy carrier with a microbial fuel cell. This novel, fast-charging biohybrid battery system can be used to monitor the toxicity of drinking water, just one of many potential future applications.

To quickly and accurately characterize prospective materials for use in solar energy, researchers built an automated system to perform laboratory experiments and used machine learning to help analyze the data they recorded. Their goal is to identify semiconductor materials for use in photovoltaic solar energy, which are highly efficient and have low toxicity.

There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme group is so sensitive to oxygen that commercial use of the hydrogen produced by this process as a green energy source is not yet possible. Researchers have now increased the oxygen stability of a hydrogen-producing enzyme by genetically generated channel blockages.

Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.

Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.

Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing visible light.

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
