Laser Direct Writing of Sol-Gel-Derived Vacancy-Rich Functional Oxide Semiconductors.

Fabricating micro/nanostructures of oxide semiconductors with oxygen vacancies (OVs) is crucial for advancing miniaturized functional devices. However, traditional methods for the synthesis of semiconductor metal oxides (SMOs) with OVs usually involve thermal treatment, such as annealing or sintering, under anaerobic conditions. Herein, a multiphoton-induced femtosecond laser (fs) additive manufacturing method is reported for directly writing micropatterns with high resolution (∼1 μm) and abundant OVs in an atmospheric environment at room temperature (25 °C).

A Chromosome-Scale Genome Assembly of Paper Mulberry (Broussonetia papyrifera) Provides New Insights into Its Forage and Papermaking Usage.

Paper mulberry (Broussonetia papyrifera) is a well-known woody tree historically used for Cai Lun papermaking, one of the four great inventions of ancient China. More recently, Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents. In this study, we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches, including Illumina and PacBio sequencing platform as well as Hi-C, optical, and genetic maps.
