source:newswiseNewswise — Beneath the Earth’s crust, super-hot rock holds the potential to provide clean, renewable energy called geothermal energy. This resource is just waiting to be tapped. However, the development of geothermal energy over the past couple decades has been hampered by significant upfront investment, financial risk, and a perceived cost higher than renewables like wind and solar. But that could all change if geothermal energy is paired with lithium extraction.Research from Pacific Northwest National Laboratory (PNNL) shows that coupling geothermal energy production with lith...

source:miragenewsThe Haber-Bosch process, which is commonly used to synthesize ammonia (NH3)–the foundation for synthetic nitrogen fertilizers–by combining hydrogen (H2) and nitrogen (N2) over catalysts at high pressures and temperatures, is one of the most important scientific discoveries that has helped improve crop yields and increase food production globally.However, the process requires high fossil fuel energy inputs due to its requirements of high temperatures and pressure. Hydrogen used for this process is produced from natural gas (mainly methane). This hydrogen-producing process is en...

source:azonanoImportance of Corrosion Protection in MetalsMetal is one of the most extensively used materials in different industrial sectors, such as medical, construction, transportation, and defense. However, metal equipment and structures are prone to corrosion when they are exposed to moisture and adverse environmental conditions. Corrosion causes gradual loss of performance in metal equipment and structures and eventually leads to their destruction.Limitations of Existing Corrosion Protection MechanismsSeveral methods based on anodic and cathodic protection, coatings, and corrosion inhib...

source:miningResearchers at Tsinghua University have devised a method for combining platinum and lanthanum as an alloy to serve as a catalyst in the next generation of fuel cells which will improve their performance and slash their cost.In a paper published in the journal Nano Research, the team behind the development points out that up until now, the type of fuel cell most commonly used in a number of devices, from satellites to the Space Shuttle, has been the alkaline fuel cell, whose invention dates back almost a century.The next generation is more likely to look something like Polymer Elec...
