Enhancing the luminescence of core-shell lanthanide-doped nanocrystals through surface modifications
Spectral and lifetime properties of the enhanced upconversion and downconversion mechanism of shell-enhanced lanthanide-doped nanocrystals revealed through luminescence spectroscopy.
Fluorescence spectroscopy has been used to study the ancient pigment, Egyptian blue.
Edinburgh Instruments have installated one of their top end fluorescence spectroscopy systems at the brand new Vidyasirimedhi Institute of Science and Technology (VISTEC) in Thailand. VISTEC is funded by PPT, a petroleum company, with the aim of producing high impact research publications in the science and technology field. The University has invested heavily in state of the art scientific facilities and recruited some of the best professors and researchers, including NRCT Research Award and Outstanding Scientist Award winners.
The FLS980 Fluorescence Spectrometer and the LP980 Transient Absorption Spectrometer will be used to investigate and improve the efficiency and photochemical characteristics of organic solar cell technology. The group researchers are aiming to reduce global consumption and dependence on fossil fuels through improving the overall light-collection efficiency and simplify the manufacture of this type of organic solar cell.
A large number of illnesses stem from misfolded proteins, molecules composed of amino acids. Researchers at the University of Zurich, Switzerland, have now studied protein misfolding using a special spectroscopic technique— single-molecule fluorescence. Misfolding, as they report in Nature, is more frequent if the sequence of the amino acids in the neighbouring protein domains is very similar.
The eyes of sheep infected with scrapie—a neurological disorder similar to mad cow disease—return an intense, almost-white glow when they're illuminated with blue excitation light, according to a research project led by Iowa State University's Jacob Petrich.
Biomedical engineers are developing a hand-held device called a SpectroPen that could help surgeons see the edges of tumours in human patients in real time during surgery. Statistics indicate that complete removal, or resection, is the single most important predictor of patient survival for most solid tumours.
There has been a renewed interest in instrumental qualification and standardisation by the fluorescence community over the last 10 years, driven by the increasing number of quantitative chemical assays that use fluorescence detection and the presence of regulations in some of these areas.
Horiba has announced the construction of a new research facility and European headquarters on the campus of the École Polytechnique in Paris. The new centre will give Horiba access to a pool of innovative technologies, resources and personnel from nearby academic, government and commercial research centres. It is due to open in late 2011. www.horiba.com/uk/scientific
One of the ten winners of the 2010 Leibnitz Prize, Petra Schwille, is recognised for her work with fluorescence correlation spectroscopy.
Agilent Technologies have signed a definitive agreement to acquire Varian, paying $1.5 billion. As well as adding $1 billion in annual sales to Agilent’s existing $5.8 billion, it significantly expands the range of technologies in Agilent’s portfolio. Varian are particularly strong in NMR, imaging and vacuum technologies, but also can offer a number of atomic and molecular spectroscopies.
Jasco Europe have concluded the celebrations of Jasco’s 50th anniversary by moving into new facilities in Cremella, Italy. The 1400 m2 new office includes sales and marketing operations, a service and customer support department, logistics, IT and a manufacturing area. www.jasco-europe.com
PerkinElmer have introduced their ExoAnalytix initiative. This is initially aimed at food and consumer product safety, water quality and sustainable energy development. The initiative will combine application-focussed solutions with information from leading scientists, industry experts and government. www.perkinelmer.com/ecoanalytix
Jasco is celebrating its 50th anniversary in the analytical instrument market. It was founded in 1958 by a group of researchers at the Institute of Optics of Tsukuba University. It has now grown to a global corporation located in over 57 countries. www.jascoeurope.com
PerkinElmer has introduced the OneSource Laboratory Relocation service. This service is available globally and is designed to handle problems laboratories face when moving equipment from one location to another. www.perkinelmer.com
