N-Doped graphene/C₆₀ covalent hybrid as a new material for energy harvesting applications (open access)

N-Doped graphene/C₆₀ covalent hybrid as a new material for energy harvesting applications

This article systematically investigates the degree of functionalization and the key structural features of the N-G/C₆₀ hybrid by a number of techniques including thermogravimetric analysis, X-ray photoelectron and Raman spectroscopies and transmission electron and atomic force microscopies.

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (RubisCO) Is Essential for Growth of the Methanotroph Methylococcus capsulatus Strain Bath (open access)

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (RubisCO) Is Essential for Growth of the Methanotroph Methylococcus capsulatus Strain Bath

This article demonstrates that shows both CO2 and RubisCO are essential for M. capsulatus Bath growth. CO2 tracing experiments supported that RubisCO mediates CO2 fixation and that a noncanonical Calvin cycle is active in this organism. The study provides insights into the expanding knowledge of methanotroph metabolism and implicates dually CH4/CO2-utilizing bacteria as more important players in the biogeochemical carbon cycle than previously appreciated. In addition, M. capsulatus and other methanotrophs with CO2 assimilation capacity represent candidate organisms for the development of biotechnologies to mitigate the two most abundant greenhouse gases, CH4 and CO2.

The Subantarctic Rayadito (Aphrastura subantarctica), a new bird species on the southernmost islands of the Americas (open access)

The Subantarctic Rayadito (Aphrastura subantarctica), a new bird species on the southernmost islands of the Americas

Article describes a new taxon of terrestrial bird of the genus Aphrastura (rayaditos) inhabiting the Diego Ramírez Archipelago, the southernmost point of the American continent. The authors state that the discovery of this endemic passerine highlights the need to monitor and conserve this still-pristine archipelago devoid of exotic species, which is now protected by the recently created Diego Ramírez Islands-Drake Passage Marine Park.

Breaking Down the Book: Literature Review and Practice of Book Digitization Methods [VRA 2023]

Presentation exploring book digitization practices and standards and share how they are implemented by the UNT Digital Projects Lab. With a large number of books flowing into their department, the authors decided to conduct research on the methods of scanning using the equipment and software available to them. This presentation reports on their findings and what factors went into deciding what type of books get scanned where and how. Results include changes to local digitizing standards and clarified workflows based on the types of books to be scanned. It was presented at the 2023 Visual Resources Association Conference held in San Antonio, Texas.
