Correlative Chemical Imaging to Reveal the Nature of Different Commercial Graphene Materials

Small Methods, EarlyView.
Commercial graphene‐based materials from different sources and of varying complexities were investigated correlatively using commonly employed imaging techniques, including SEM, AFM, ToF‐SIMS, AES, and EDS. ToF‐SIMS combined with SEM was identified as the most effective combination for simultaneously resolving the complex morphology and chemical ...

Benzochromanone and Benzochromene Natural Products: Synthetic Strategies and Total Syntheses

The Chemical Record, EarlyView.
This work outlines synthetic strategies for natural products with benzochromanone and benzochromene cores. Key achievements include total syntheses of xanthones, blennolide C, gonytolide C, and teretifolione B. Spirochromanone intermediates, benzyne–furan Diels–Alder reactions, and enzymatic resolution enabled efficient and enantioselective access to ...

Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

Environmental Toxicology, EarlyView.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...
