Designing Surface-Defect Engineering to Enhance the Solar-Driven Conversion of CO to C Products over ZnInS/ZnS.

The manipulation of electronic structure and prevention of photogenerated carriers from being quenched in bulk defects during the photocatalytic CO reduction reaction (CRR) have been effectively demonstrated through surface vacancy and defect engineering. In this work, the electronic structure on the surface of ZnInS/ZnS (ZIS/ZnS) is significantly modified by the introduction and control of the surface S vacancies (S) through Ar-plasma treatment. EPR and XPS analyses confirmed that S was exclusively present on the ZIS/ZnS surface.

Select, Purify, and Exchange: A Multisource Unsupervised Domain Adaptation Method for Building Extraction.

Accurately extracting buildings from aerial images has essential research significance for timely understanding human intervention on the land. The distribution discrepancies between diversified unlabeled remote sensing images (changes in imaging sensor, location, and environment) and labeled historical images significantly degrade the generalization performance of deep learning algorithms. Unsupervised domain adaptation (UDA) algorithms have recently been proposed to eliminate the distribution discrepancies without re-annotating training data for new domains.

Rapid screening of illegally added drugs in functional food using a miniature ion trap mass spectrometer.

With the expansion of the functional food market, the qualification assessment of these products has become a major challenge, and efficient analytical tools are urgently needed. Here, a miniature mass spectrometer (MS) with self-aspiration capillary electrospray ionization (SACESI) source and ion trap analyzer was developed for rapid screening of various illegally added drugs in functional foods. No chromatographic separation was required, but a simplified two-step pretreatment method was developed to reduce the operational procedures and time consumption of the entire analysis.

Identification of grape H3K4 genes and their expression profiles during grape fruit ripening and postharvest ROS treatment.

Fruit development is modified by different types of epigenetics. Histone methylation is an important way of epigenetic modification. Eight genes related to H3K4 methyltransferase, named VvH3K4s, were identified and isolated from the grape genome based on conserved domain analysis, which could be divided into 3 categories by the phylogenetic relationship.
