Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

open access: yesAdvanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...

Menadione-induced oxidative stress re-shapes the oxylipin profile of Aspergillus flavus and its lifestyle [PDF]

open access: yes, 2015
Aspergillus flavus is an efficient producer of mycotoxins, particularly aflatoxin B1, probably the most hepatocarcinogenic naturally-occurring compound.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

open access: yesAdvanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Charge transfer tuning in TiO2 hybrid nanostructures with acceptor-acceptor systems

open access: yes, 2017
An interesting interplay between two different modifiers and the surface of titanium dioxide leads to a significant change in photoelectrochemical properties of the designed hybrid materials.

Ochratoxin A: In Utero Exposure in Mice Induces Adducts in Testicular DNA [PDF]

open access: yes, 2010
Ochratoxin A (OTA) is a nephrotoxin and carcinogen that is associated with Balkan endemic nephropathy and urinary tract tumors. OTA crosses the placenta and causes adducts in the liver and kidney DNA of newborns.

Quinone and non-quinone redox couples in Complex III [PDF]

open access: yesJournal of Bioenergetics and Biomembranes, 2008
The Q cycle mechanism proposed by Peter Mitchell in the 1970's explicitly considered the modification of ubiquinone two-electron redox properties upon binding to Complex III to match the thermodynamics of the other single-electron redox cofactors in the complex, and guide electron transfer to support the generation of a proton electro-chemical gradient

Glutathione (GSH) conjugates with dopamine (DA)-derived quinones to form reactive or non-reactive GSH-conjugates [PDF]

open access: yes, 2009
In this study we demonstrate for the first time that GSH could rapidly conjugate with dopamine (DA)-derived DA-o-quinones without enzymatic catalysis to form short-lived intermediate GSH-conjugates (2-S-GSH-DA-o-quinone and 5-S-GSH-DA-o-quinone).

Symmetric All-Quinone Aqueous Battery

open access: yesACS Applied Energy Materials, 2019
Here we report a symmetric all-quinone aqueous battery based entirely on earth-abundant elements that uses a naturally occurring dye as the redox-active material in both positive and negative electrodes.
