Journal Highlight: Multicolor fluorescence writing based on host–guest interactions and force-induced fluorescence-color memory

Date: Aug 10, 2015

Author: spectroscopyNOW

A new strategy for multicolor fluorescence writing on thin solid films with mechanical forces has been illustrated by the use of a green-fluorescent pentiptycene derivative which forms variably colored fluorescent exciplexes.

Pear review: Organic UVC cleanup

Date: Aug 1, 2015

Author: David Bradley

Some kinds of organic fruit can be scrubbed of foodborne pathogens, such as E coli and Listeria present on their surfaces using ultraviolet-C radiation, according to a new study from researchers at Washington State University.

Journal Highlight: Nonlinear optical properties and temperature-dependent UV–Vis absorption and photoluminescence emission in 2D hexagonal boron nitride nanosheets

Date: Jul 6, 2015

Author: spectroscopyNOW

Nonlinear optical properties of 2D hexagonal boron nitride nanosheets have been reported for the first time, suggesting that it might be useful as an optical material for multiphoton bioimaging and advanced photonic devices.

Coral See: UV sheds light on colourful array

Date: Jul 1, 2015

Author: David Bradley

Oceanic corals are well known for their beautiful shapes and forms, for their range of colours and for their wondrous role in submarine ecosystems. Now, ultraviolet light reveals a surprising display of colours and  fluorescence in the corals that reside on the deep water reefs of  the Red Sea. The discovery of this new beauty was made by scientists from the University of Southampton, UK, Tel  Aviv University and the Interuniversity Institute for Marine Sciences  (IUI), in Israel, and...

Journal Highlight: Effect of thiophene rings on UV/visible spectra and non-linear optical (NLO) properties of triphenylamine based dyes: a quantum chemical perspective

Date: Jun 8, 2015

Author: spectroscopyNOW

Density functional theory (DFT) and time-dependent DFT are used to show how the number of thiophene rings in π-conjugated systems influence the absorption spectra and non-linear optical properties of dyes.

Journal Highlight: Real-time fluorescence imaging of the DNA damage repair response during mitosis

Date: May 11, 2015

Author: spectroscopyNOW

The response to DNA damage during mitosis was visualized using real-time fluorescence imaging of focus formation by the DNA-damage repair response protein 53BP1 linked to green fluorescent protein in the MiaPaCa-2Tet-On pancreatic cancer cell line.

How difficile can it be? Microbes under UV

Date: May 1, 2015

Author: David Bradley

The bacterium Clostridium difficile kills almost 30000 people annually in the US and causes sickness in hundreds of thousands more. A new study reveals that close to half of American hospitals are not taking simple, but critical, steps to prevent its spread despite strong evidence of efficacy of such actions.

Venus running hot and cold: Ultraviolet layer

Date: Apr 1, 2015

Author: David Bradley

Ultraviolet observations by an international team reveal the existence of a warm layer in the atmosphere of the planet Venus the origins of which are yet to be explained. The discovery was uncovered when the team built a temperature map of the upper atmosphere on the planet's night side using data collected by the Venus Express probe.
