2H‐Au Nanosheet‐Templated Growth of PdFe for Electrocatalytic Methanol Oxidation

Advanced Functional Materials, EarlyView.
2H‐to‐face‐centered cubic (fcc) phase transformation of 2H‐Au happens when PdFe alloy epitaxially grows on 2H‐Au nanosheets (NSs), forming 2H/fcc Au@PdFe NSs, and the 2H/fcc phase ratio in 2H/fcc Au@PdFe NSs can be tuned correspondingly by changing the Pd/Fe atomic ratio.

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

Advanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...
