Intramolecular Torque, an Indicator of the Internal Rotation Direction of Rotor Molecules and Similar Systems

, 2016
Torque is ubiquitous in many molecular systems, including collisions, chemical reactions, vibrations, electronic excitations and especially rotor molecules. We present a straightforward theoretical method based on forces acting on atoms and obtained from

Optogenetics and deep brain stimulation neurotechnologies [PDF]

, 2015
Brain neural network is composed of densely packed, intricately wired neurons whose activity patterns ultimately give rise to every behavior, thought, or emotion that we experience. Over the past decade, a novel neurotechnique, optogenetics that combines

Unveiling the role of dark states in dynamic control of azopyrrole photoisomerization by light-matter interaction

Communications Chemistry
Strong light-matter interactions demonstrated considerable potential to control photochemical reactions. Here, we coupled a single cavity mode to the electronic S0-S1 transition of azopyrrole E and Z-isomers.

UV and VUV spectroscopy and photochemistry of small molecules in a supersonic jet [PDF]

, 1990
UV and VUV absorption and emission spectroscopy is used to probe jet cooled molecules, free radicals, and clusters in the gas phase. Due to efficient cooling inhomogeneous effects on spectral line widths are eliminated. Therefore from these spectra, both

A computational study of photoisomerization in Al3O3- ­clusters [PDF]

, 2002
Ab initio calculations are employed to understand the photoisomerization process in small Al3O3- clusters. This process is the first example of a photoinduced isomerization observed in an anion cluster gas-phase system.

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

Angewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

Concentration dependence of thermal isomerization process of methyl orange in ethanol [PDF]

, 2017
The thermal isomerization (TI) rates of methyl orange (MO) and 4-dimethylaminoazobenzene (DMAAB) in ethanol (EtOH) are measured. Usually TI rates of azobenzene dyes are known to be concentration independent.

Kinetics of photoinduced ordering in azo-dye films: two-state and diffusion models

, 2008
We study the kinetics of photoinduced ordering in the azo-dye SD1 photoaligning layers and present the results of modeling performed using two different phenomenological approaches.
