Femtosecond spectral and anisotropy study of excitation energy transfer between neighbouring α-80 and β-81 chromophores of allophycocyanin trimers [PDF]

, 1994
Polarization pump-probe femtosecond spectroscopy was used to investigate photoinduced optical density changes in allophycocyanin (APC) trimers at 635–690 nm after excitation with 230-fs pulses at 618 nm.

Combination Analysis of Metatranscriptome and Metagenome Reveal the Composition and Functional Response of Coral Symbionts to Bleaching During an El Niño Event

Frontiers in Microbiology, 2020
With the abnormal rise in ocean temperatures globally in recent years, coral bleaching is becoming common and serious. However, the response mechanisms and processes of coral symbionts to bleaching are not well understood. In this study, metagenomics and

Development of a controlled environment near-field optical microscope for organic thin film studies [PDF]

, 2010
The requirements of a microscope differ greatly from field to field and with the sample being studied Organic thin films are highly sensitive to environmental conditions being rapidly photobleached in the presence of oxygen In this paper we introduce the

Comparison of Casein Phosphopeptide with Potassium Nitrate and Sodium Monofluorophosphate Desensitizing Efficacy after In-Office Vital Bleaching—A Randomized Trial

Applied Sciences, 2021
Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), potassium nitrate, and sodium monofluorophosphate are desensitizing agents that help in reducing teeth sensitivity. However, indecisive evidence exists regarding their efficacy. Therefore, this

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
