Published Direct power generation from methylcyclohexane using solid oxide fuel cells
(via sciencedaily.com) Original source Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.
Published Quantum computer unveils atomic dynamics of light-sensitive molecules
(via sciencedaily.com) Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
Published Which radio waves disrupt the magnetic sense in migratory birds?
(via sciencedaily.com) Many songbirds use the earth's magnetic field as a guide during their migrations, but radiowaves interfere with this ability. A new study has found an upper bound for the frequency that disrupts the magnetic compass.

Published Steam condenser coating could save 460M tons of CO2 annually
(via sciencedaily.com) If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.
Published 'Topological gardening' to achieve unexpected spin transport
(via sciencedaily.com) 'Trimming' the edge-states of a topological insulator yields a new class of material featuring unconventional 'two way' edge transport in a new theoretical study. The new material, a topological crystalline insulator (TCI) forms a promising addition to the family of topological materials and significantly broadens the scope of materials with topologically nontrivial properties, paving the way for novel techniques to manipulate edge transport in future electronics. For example, 'switching' the TCI via an electric field breaking the symmetry supporting the nontrivial band topology, thus suppressing the edge current.
