Kinetics versus thermodynamics in virus capsid polymorphism [PDF]

, 2016
Virus coat proteins spontaneously self-assemble into empty shells in aqueous solution under the appropriate physicochemical conditions, driven by an interaction free energy per bond on the order of 2-5 times the thermal energy kBT.

Biomimetic light-harvesting funnels for re-directioning of diffuse light

Nature Communications, 2018
Sunlight harvesting and redirection is a promising concept for sustainable energy conversion, however losses have hindered progress. Here the authors construct a simple biomimetic device which minimises losses by using reservoirs of randomly-oriented ...

Simultaneous measurement of rotational and translational diffusion of anisotropic colloids with a new integrated setup for fluorescence recovery after photobleaching [PDF]

, 2012
This paper describes an integrated setup for fluorescence recovery after photobleaching (FRAP) for determining translational and rotational Brownian diffusion simultaneously, ensuring that these two quantities are measured under exactly the same ...

Synthesis of Nanometer Sized Bis- and Tris-trityl Model Compounds with Different Extent of Spin–Spin Coupling

Molecules, 2018
Tris(2,3,5,6-tetrathiaaryl)methyl radicals, so-called trityl radicals, are emerging as spin labels for distance measurements in biological systems based on Electron Paramagnetic Resonance (EPR).

Understanding the Sensing Mechanism of Rh₂O₃ loaded In₂O₃

Proceedings, 2018
The effect of Rh loading on CO sensing was studied for the case of In2O3. This was done by performing measurements with sensors based on loaded and unloaded materials that were performed at an operation temperature of 300 °C in the presence of low ...

Strong inverse kinetic isotope effect observed in ammonia charge exchange reactions

Nature Communications, 2020
Inverse kinetic isotope effects (KIEs) are rarely observed. Here, the authors report an inverse KIE in the charge transfer reaction of $${{\rm{Xe}}}^{+}$$ Xe+ with ammonia.

Computational physical organic chemistry using the empirical valence bond approach

, 2019
There has been growing interest in applying the empirical valence bond approach to a range of (bio)chemical problems, primarily to study enzymatic and non-enzymatic catalysis, but also to studying other processes such as excited state chemistry and ...
