Functional analysis and structural investigations of MTB DosS sensory domain.

open access: yes, 2007
Mycobacterium tuberculosis (MTB) is a very successful pathogen, causing the deaths of approximately two million people a year world-wide. Survival of the pathogen in vivo is dependant on its ability to respond and adapt to changes within its environment.

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

A polyphasic approach to the study of chitinolytic bacteria in soil [PDF]

open access: yes
Chitin is the most abundant nitrogen-containing polymer in nature, with >1x10^10 tonnes produced annually in terrestrial and marine habitats. Chitinolytic bacteria are able to degrade this recalcitrant substrate through a multiplicity of chitinases.
