Dynamics of polydisperse irreversible adsorption: a pharmacological example [PDF]

open access: yes, 2006
Many drug delivery systems suffer from undesirable interactions with the host immune system. It has been experimentally established that covalent attachment (irreversible adsorption) of suitable macromolecules to the surface of the drug carrier can ...

Two-Dimensional Quantum Dynamics of O$_2$ Dissociative Adsorption on Ag(111) [PDF]

open access: yes, 2014
We have investigated the quantum dynamics of O2 dissociative adsorption on a Ag(111) surface. We performed the calculations with a Hamiltonian where the O2 translational motion is perpendicular to the surface and for O2 vibrational energy.

Adsorption mechanism and improvements of the adsorption equation for adsorption refrigeration pairs

open access: yesInternational Journal of Energy Research, 1999
An improved adsorption model for adsorption refrigeration pairs such as activated carbon-methanol and zeolite-water is suggested based upon normal Dubinin adsorption equations. This model has been verified by various experimental results.

Upcycling polyethylene into closed-loop recyclable polymers through titanosilicate catalyzed C-H oxidation and in-chain heteroatom insertion

open access: yesNature Communications
Polyolefins are the most widely produced type of plastics owing to their low production cost and favorable properties. Their polymer backbone consists solely of inert C-C bonds, making them resistant and durable materials.

Lead‐free perovskite MASnBr3‐based memristor for quaternary information storage

open access: yesInfoMat, 2020
Memristors are a new type of circuit element with a resistance that is tunable to discrete levels by a voltage/current and sustainable after removal of power, allowing for low‐power computation and multilevel information storage.

Sensing behavior of acetone vapors on TiO$_2$ nanostructures --- application of density functional theory [PDF]

open access: yes, 2017
The electronic properties of TiO$_2$ nanostructure are explored using density functional theory. The adsorption properties of acetone on TiO$_2$ nanostructure are studied in terms of adsorption energy, average energy gap variation and Mulliken charge ...

The atypical KRASQ22K mutation directs TGF‐β response towards partial epithelial‐to‐mesenchymal transition in patient‐derived colorectal cancer tumoroids

open access: yesMolecular Oncology, EarlyView.
TGF‐β has a complex role in cancer, exhibiting both tumor‐suppressive and tumor‐promoting properties. Using a series of differentiated tumoroids, derived from different stages and mutational background of colorectal cancer patients, we replicate this duality of TGF‐β in vitro. Notably, the atypical but highly aggressive KRASQ22K mutation rendered early‐
