Fluorescence spectroscopy using a smartphone
09-Nov-2012
Scientists in Germany have used digital photographs to extract colour and spectral information of reactive fluorophores. They studied the optical properties of different pyridine-substituted cross-conjugated fluorophores (XF). Upon protonation of the pyridine nitrogen, the colour changes of XFs ...
450-year-old metal analysed at the nanometre level for finer detail of corrosion mechanism
09-Nov-2012
Corrosion products of a 450-year-old archaeological metal were investigated at the nanometre level using scanning transmission x-ray microscopy by scientists in France and Canada. The work is on a much finer scale than others, which usually analyse the microscale with methods like transmission ...
Titania photocatalyst produces hydrogen and generates photocurrents under visible light
09-Oct-2012
Combining a cheap polymer resin with titania produces a photocatalyst that can produce hydrogen and generate photocurrents under visible light, say scientists in the Republic of Korea. Titania is commonly used as a base material for solar energy conversion. But it has a wide band gap so doesn’t ...
Sequential synthesis to integrate catalysts – no need to purify
09-Oct-2012
Scientists from Spain have developed a new method for increasing yields in synthetic organic reactions. One pot syntheses may seem like an attractive option for syntheses with multiple reaction steps but reagents are not always compatible, leading to serious reductions in yields. An alternative ...
How much caffeine is in your coffee?
05-Dec-2011
Substantial differences exist in the caffeine and chlorogenic acid contents of espresso coffees that can result in over-consumption by consumers at risk of caffeine toxicity, say scientists in the UK. The team carried out high performance liquid chromatography analysis of 20 commercial espresso ...
Materials: The first graphene-based chiral sensor
03-Aug-2011
A reusable, natural and cheap amylose-functionalised graphene sensor was developed for highly sensitive and visual fluorescent chiral sensing by a team in China.The team found that the sensor’s detection sensitivity toward L-tryptophan was over 100 times higher than that of recently reported ...
