Mutagenic and Spectroscopic Investigation of pH Dependent CooA DNA Binding [PDF]

open access: yes, 2017
The carbon monoxide (CO) sensing heme protein, CooA, is a transcription factor which exists in several bacteria that utilize CO as an energy source. CooA positively regulates the expression of coo genes in the presence of CO such that the corresponding ...

Real-Time PCR Measurement by Fluorescence Anisotropy [PDF]

open access: yesAnalytical Chemistry, 2005
We have developed an instrument for monitoring real-time PCR using fluorescence anisotropy, enabling an assay chemistry in which the fluorescence from a labeled primer elucidates amplification. The instrument holds the sample temperature constant to within +/-0.03 degrees C during measurement in the extension phase of each PCR cycle and achieves 0.116 ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Optical anisotropy of CsPbBr3 perovskite nanoplatelets

open access: yesNano Convergence, 2023
The two-dimensional CsPbBr3 nanoplatelets have a quantum well electronic structure with a band gap tunable with sample thicknesses in discreet steps based upon the number of monolayers.

Fluorescence Polarization/Anisotropy in Diagnostics and Imaging [PDF]

open access: yesChemical Reviews, 2010
Fluorescence polarization was first applied in biochemistry almost 6 decades ago, when Gregorio Weber described his studies on bovine serum albumin and ovalbumin conjugated with 1-dimethylaminonaphthalene-5-sulfonyl chloride (dansyl chloride)1,2 (Figure 1).

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Genotype-induced changes in biophysical properties of frontal cortex lipid raft from APP/PS1 transgenic mice

open access: yesFrontiers in Physiology, 2012
Alterations in the lipid composition of lipid rafts have been demonstrated both in human brain and transgenic mouse models, and it has been postulated that aberrant lipid composition in lipid rafts is partly responsible for neuronal degeneration.

The nature of the silicaphilic fluorescence of PDMPO [PDF]

open access: yes, 2015
PDMPO (2-(4-pyridyl)-5-((4-(2-dimethylaminoethylaminocarbamoyl)methoxy)phenyl)oxazole), has unique silica specific fluorescence and is used in biology to understand biosilicification.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

Turbulent Mixing in Transverse Jets [PDF]

open access: yes, 2001
Turbulent mixing is studied in liquid-phase transverse jets. Jet-fluid concentration fields were measured using laser-induced fluorescence and digital-imaging techniques, for jets in the Reynolds number range 1000
