Photoelectric Imaging of the Optically Inactive Charge State of Silicon‐Vacancy Defects in Diamond
Advanced Science, EarlyView.Although the doubly negative charge state of the SiV center in diamond is predicted to ionize only in the ultraviolet and is therefore considered optically inaccessible, we demonstrate visible‐range photoelectric imaging enabled by a previously unrecognized regime of laser‐assisted tunneling. ABSTRACT The investigation of optically active point defects

Evaluation of extraradicular pH after intracoronal bleaching using four bleaching agents
Brazilian Dental Science, 2010 The present in vitro study evaluated the pH values of extraradicular medium after intracoronal bleaching with 30% hydrogen peroxide or 10% carbamide peroxide and different associations of sodium perborate.

Advanced Science, EarlyView.TAB–2TFSI enables efficient ion‐pair doping across a wide range of conjugated polymers, where the strongly oxidizing TAB core drives charge transfer, and the TFSI counterions promote favorable ionic compensation. This dicationic dopant promotes uniform dopant distribution, improves structural order, and increases carrier delocalization, establishing a ...

Advanced Science, EarlyView.DTBEI@CS@MnO2, fabricated via modular electrostatic co‐engineering and photothermal/photodynamic immunogenic cell death, specifically responds to the acidic and GSH‐rich tumor microenvironment. This triggers the release of DTBEI that provides tumor antigens, DNA, and DAMPs, as well as the generation of Mn2+, thereby synergistically potentiating cGAS ...

Severity of 2005 Caribbean Bleaching
, 2016 Shown here is an image that plots the accumulated heat stress that corals in the Caribbean experienced in 2005 and compares it with the conditions in 2010. Reports indicated widespread bleaching.

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation
Advanced Science, EarlyView.Using a newly developed Droplet Interface Bilayer‐Pipette assay, the authors show that two segments of the CyaA toxin cross membranes by distinct mechanisms. One segment translocates spontaneously, whereas the translocation of the other depends on membrane potential.
