UV radiation from a relativistic electron beam is diffracted by a double-slit. In contrast to the normal light (left), the diffraction shows a deformation in the central part (right), indicating the existence of the phase singularity, which is a definite evidence of the vortex nature.
Berkeley Lab scientist Tim Kneafsey demonstrates how he places rock samples, from the Brady Geothermal Field in Nevada, into a stress permeability apparatus, which tests how long a fracture can remain open.

Excited-state intramolecular proton transfer (ESIPT) makes possible organic light-emitting diodes (OLEDs) that are highly efficient by creating the necessary conditions to enable thermally activated delayed fluorescence (TADF). After excitation of the emitting molecule, a hydrogen atom -- technically, just its nucleus -- is transferred to a different atom in the same molecule through a process called ESIPT. The reconfigured molecule can then undergo TADF to convert a high fraction of the excitations into light. Following emission, the molecule returns to its original state. This mechanism increases the molecular design strategies available for the creation of novel and improved light-emitting materials.

Drexel University researchers have developed two new electrode designs, using MXene material, that will allow batteries to charge much faster. The key is a microporous design that allows ions to quickly make their way to redox active sites.
Researchers at the University of Texas at Dallas and Seoul National University have designed a novel battery cathode material that offers a potentially lower-cost, more eco-friendly option to lithium-ion batteries. Their sodium-ion design, which retains the high energy density of a lithium-ion cathode, replaces the most of the lithium atoms (green) with sodium (yellow). The layered structure of the new material also incorporates manganese (purple) and oxygen (red). The research is published in the journal Advanced Materials.
Enzymes, genetically engineered to avoid sticking to the surfaces of biomass such as corn stalks, may lower costs in the production of cellulose-based biofuels like ethanol.
Genome-wide distribution of fast-neutron-induced mutations in the Kitaake rice mutant population (green). The genome-wide distribution of mutations indicates a non-biased saturation of the genome. Colored lines (center) represent translocations of DNA fragments from one chromosome to another.
