Angewandte Chemie, EarlyView.The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases. [PDF]
ChembiochemProtein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Holographic Floquet states I: a strongly coupled Weyl semimetal
Journal of High Energy Physics, 2017 Floquet states can be realized in quantum systems driven by continuous time-periodic perturbations. It is known that a state known as the Floquet Weyl semimetal can be realized when free Dirac fermions are placed in a rotating electric field.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing
Advanced Materials, EarlyView.This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Physics from Time Variability of the VHE Blazar PKS 2155-304 [PDF]
, 2010 Blazars are the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma ...

PK+ Tree: An Improved Spatial Index Structure of PK Tree [PDF]
, 2005 Spatial index is very important in GIS. PK tree and Hilbert R tree are two well-known spatial index structures. Comparison operations are very little in PK tree, while disk I/O operations are quite little in Hilbert R tree. PK+ Tree is an improved spatial index structure from PK tree.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives
Advanced Materials, EarlyView.Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for
