Effect of Salinity on Silica Nanoparticle Adsorption Kinetics and Mechanisms for Fluid/Rock Interaction with Calcite

open access: yesNanomaterials, 2019
This study addresses the kinetics of silica nanoparticle adsorption on calcite from a solution at three salinities: deionized water (DIW), synthetic seawater (SSW), and low salinity water (LSW).

Optical Polarization of $^{13}$C Nuclei in Diamond through Nitrogen-Vacancy Centers [PDF]

open access: yes, 2010
We determine the polarization of the bulk $^{13}$C nuclear spin system in diamond produced by interaction with optically oriented nitrogen-vacancy (NV-) defect centers. $^{13}$C nuclei are polarized into the higher energy Zeeman state with a bulk-average

Dissection of Interaction Kinetics through Single-Molecule Interaction Simulation

open access: yesAnalytical Chemistry, 2020
The ability to extract kinetic interaction parameters from single-molecule fluorescence resonance energy transfer trajectories without the need for solving complex single-molecule differential equations has the potential to address some of the critical biophysical questions.

Differential regulation of alternative promoters emerges from unified kinetics of enhancer-promoter interaction

open access: yesNature Communications, 2022
Alternative promoters differ in their expression patterns, whose mechanisms are not well understood. Here the authors show that alternative promoters of a Drosophila embryonic gene hunchback are regulated by different action modes of two enhancers.

Impact of histone H4 lysine 20 methylation on 53BP1 responses to chromosomal double strand breaks. [PDF]

open access: yes, 2012
Recruitment of 53BP1 to chromatin flanking double strand breaks (DSBs) requires γH2AX/MDC1/RNF8-dependent ubiquitination of chromatin and interaction of 53BP1 with histone H4 methylated on lysine 20 (H4K20me). Several histone methyltransferases have been

Analysis of Dissolution of Salicylamide from Carrageenan Based Hard-Shell Capsules: A Study of the Drug-Matrix Interaction

open access: yesIndonesian Journal of Chemistry, 2020
In drug release kinetics, the drug-matrix interaction is one of the important mechanisms to be dictated. Unfortunately, there is still minimum information discussing the effect of interaction between a drug and its matrix to the release profile of the ...

Ordering Dynamics in Neuron Activity Pattern Model: An Insight to Brain Functionality.

open access: yesPLoS ONE, 2015
We study the domain ordering kinetics in d = 2 ferromagnets which corresponds to populated neuron activities with both long-ranged interactions, V(r) ∼ r-n and short-ranged interactions.

Control of kinetics by cooperative interactions [PDF]

open access: yesIUBMB Life, 2011
AbstractCooperative effects in ligand binding and dissociation kinetics are much less investigated than steady state kinetics or equilibrium binding. Nevertheless, cooperativity in ligand binding leads necessarily to characteristic properties with respect to kinetic properties of the system.

Interaction and Kinetics Study of the Co-Gasification of High-solid Anaerobic Digestate and Lignite

open access: yesMolecules, 2020
This study aims at investigating the interaction and kinetics behavior of the co-gasification of digestate and lignite. The co-pyrolysis performances of digestate and lignite blended by dry process were better than that blended by wet process, while the ...
