Fabrication of monodisperse gold-copper nanocubes and AuCu-cuprous sulfide heterodimers by a step-wise polyol reduction

Atomic-Scale Engineering of CuOx–Au Interfaces over AuCu Single-Nanoparticles

“…Monodisperse AuCu colloids were prepared by a seed-mediated polyol reduction, as we described recently . HAuCl 4 ·4H 2 O (100 mg) and oleylamine (10 mL) were dissolved in 100 mL of ethylene glycol at room temperature; the mixture was heated to 443 K under stirring and maintained at that temperature for 30 min under Ar flow, forming the Au seeds.…”

“…Monodisperse AuCu colloids were prepared by a seed-mediated polyol reduction, as we described recently. 27 HAuCl 4 •4H 2 O (100 mg) and oleylamine (10 mL) were dissolved in 100 mL of ethylene glycol at room temperature; the mixture was heated to 443 K under stirring and maintained at that temperature for 30 min under Ar flow, forming the Au seeds. Then, a solution containing 62 mg of CuCl 2 •2H 2 O, 2 mL of oleylamine, and 20 mL of ethylene glycol was slowly added and the mixture was heated to 473 K and kept at that temperature for 2 h. After cooling down to room temperature, the solid product was extracted by a mixed solution of ethanol and hexane, precipitated by acetone, and separated by centrifugation, yielding the AuCu colloids.…”

A comprehensive review of Siraitia grosvenorii (Swingle) C. Jeffrey: chemical composition, pharmacology, toxicology, status of resources development, and applications

“…As its residual components find utility in enhancing feed digestibility, augmenting poultry growth, and ameliorating slaughter performance, evident in the supplementation of Guangxi hemp chicken diets with S. grosvenorii residues ( Xu et al, 2022a ; Wang et al, 2023 ; Xiao et al, 2023 ). Furthermore, incorporating S. grosvenorii flavoring into smoking products not only enhances the sensory experience but also helps protect the health of smokers by reducing harmful pulmonary consequences, alleviating throat irritation, and even aiding smoking cessation ( Li et al, 2006a ; Zhang et al, 2018 ; Wu et al, 2022b ). Moreover, there are many patented products of S. grosvenorii that find applications in the cosmetic industry due to their skin whitening and moisturizing effects ( Zhang and Zhang, 2011 ; Yang, 2022 ).…”
