Re-entrant phase diagram and pH effects in cross-linked gelatin gels

open access: yes, 2008
Experimental results have shown that the kinetics of bond formation in chemical cross-linking of gelatin solutions are strongly affected not only by gelatin and reactant concentrations but also by the solution pH.

First Principles Electrochemical Study of Redox Events in DNA Bases and Chemical Repair in Aqueous Solution

open access: yes, 2004
Primary and secondary radiation-induced damage to DNA, and chemical repair of the lesions on the nucleobases in solution involve a cascade of proton transfer (PT), electron transfer (ET), and proton-coupled electron transfer (PT-ET) reactions.

Journal of Applied Physics

open access: yes, 2015
Multilayer films with up to 600 bilayers and 740 nm thickness were fabricated using the alternating deposition of poly(allylamine hydrochloride) and poly{1-[p-(3'-carboxy-4'-hydroxyphenylazo)benzenesulfonamido]-1,2-ethand iyl} on glass substrates. Linear

Predicting O-17 NMR chemical shifts of polyoxometalates using density functional theory

open access: yes, 2016
We have investigated the computation of O-17 NMR chemical shifts of a wide range of polyoxometalates using density functional theory. The effects of basis sets and exchange-correlation functionals are explored, and whereas pure DFT functionals generally ...

Laser-induced tuning of graphene field-effect transistors for pH sensing

open access: yes, 2023
Here we demonstrate, using pulsed femtosecond laser-induced two-photon oxidation (2PO), a novel method of locally tuning the sensitivity of solution gated graphene field-effect transistors (GFETs) without sacrificing the integrity of the carbon network ...
