Cavity Catalysis by Cooperative Vibrational Strong Coupling of Reactant and Solvent Molecules

open access: yesAngewandte Chemie, 2018
Here, we report the catalytic effect of vibrational strong coupling (VSC) on the solvolysis of para‐nitrophenyl acetate (PNPA), which increases the reaction rate by an order of magnitude. This is observed when the microfluidic Fabry–Perot cavity in which

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Porosity and morphology control of mesoporous Cu-BTC Metal-Organic Framework microparticles [PDF]

open access: yesProgress in Physics of Applied Materials
In this study, Cu-BTC structures, one of the most widely used metal-organic frameworks (MOF), were synthesized by solvothermal technique, and the effect of metal-to-ligand ratio and the solvent content on their crystalline structure, chemical bonding ...

Influence of Solvent Coordination on Hybrid Organic–Inorganic Perovskite Formation

open access: yes, 2018
Solution-processed hybrid organic–inorganic perovskites (HOIPs) from organoammonium halide and lead halide precursors form efficacious active layers for photovoltaics, light-emitting diodes, and flexible electronics.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Generalized Born Implicit Solvent Models for Biomolecules.

open access: yesAnnual Review of Biophysics, 2019
It would often be useful in computer simulations to use an implicit description of solvation effects, instead of explicitly representing the individual solvent molecules. Continuum dielectric models often work well in describing the thermodynamic aspects

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

A thermodynamic approach to choosing pervaporatives membranes

open access: yesIngeniería e Investigación, 2006
This work describes separating a mixture of several components obtained as a product of methyl polymethyl metha- crylate (PMMA) thermo-degradation. It was aimed at purifying methyl methacrylate monomer (MMA) obtained by 95% mass thermal degradation to ...

Gaussian field theory for the Brownian motion of a solvated particle

open access: yes, 2013
An alternative derivation of Brownian motion is presented. Instead of supplementing the linearized Navier-Stokes equation with a fluctuating force, we directly assume a Gaussian action functional for solvent velocity fluctuations.
