Quantum dots made from fool’s gold boost battery performance（图）
Quantum dots fool’s gold battery performance
2015/12/7
If you add quantum dots – nanocrystals 10,000 times smaller than the width of a human hair – to a smartphone battery it will charge in 30 seconds, but the effect only lasts for a few recharge cycles.H...
Simultaneous and sensitive detection of dopamine and uric acid using a poly(L-methionine)/gold nanoparticle-modified glassy carbon electrode
Voltammetry Gold nanoparticle Poly Dopamine Uric acid
2014/3/8
A novel electrochemical sensor was fabricated by electrodeposition of gold nanoparticles on a poly(L-methionine) (PMT)-modified glassy carbon electrode (GCE) to form a nano-Au/PMT composite-modified G...
Kinetics of Oxidation of L-Leucine by Mono- and Bimetallic Gold and Silver Nanoparticles in Hydrogen Peroxide Solution（图）

Preyssler acid H14[NaP5W30O110] was used as reducing agent and stabilizer for the synthesis of gold nanoparticles by photolysis of Au(III)/Preyssler acid/propan-2-ol solution. Preyssler acid plays bot...
Identification of Active Sites and Influence of Real Structure of Gold Catalysts in the Selective Hydrogenation of Acrolein to Allyl Alcohol
Gold Catalysts Selective Hydrogenation
2009/7/29
We have successfully employed oxide supported gold
catalysts in the gas-phase hydrogenation of acrolein, the
,-unsaturated aldehyde being most difficult to
hydrogenate at the carbonyl group. The ...
The widely used cyanidation technology is not
applicable to some gold ores due to economic or
technical reasons when the cyanidation gives very low
gold extractions. Despite the fact that the gold ...
