aureus was 15 mg mL−1 when the aldehyde content was around 6.5 mmol g−1 [157]. Fig. 8 Adapted from [151] with permission Scheme of the antibacterial mechanism for DANFC. Full size image 4.3 Carboxyl-Modified Cellulose Nanostructures Carboxyl-modified CNCs are not potent antibacterial ...
Furthermore, we investigated the prediction performance on the cases where the corresponding biological activities increased or decreased by at least three orders of magnitude because these cases are relevant to the activity cliff phenomenon in medicinal chemistry. Finally, we selected four cases that ...
In spite of the extensive studies over several decades, the (bio)chemistry and pharmacology of Cr(III) are still poorly understood. The initially proposed active low molecular weight Cr(III)-binding peptide (chromodulin) has never been reproducibly identified8. It is generally believed that Cr(II...
It should be noted that China's political scheme has a top-down structure, such that the provincial legislation cannot be independent of the national system. Once the central government adopts a national strategy to support the blue energy economy, full cooperation among provinces will be ...

Alternatively, developing hybrid water electrolysis is crucial for advancing a sustainable energy scheme. In this review, we focus on recent advances in the CF-derived electrodes as highly efficient electrocatalysts for conventional water electrolysis and hybrid water electrolysis. Catalyst design and ...
