Terthiophene on Au(111): A scanning tunneling microscopy and spectroscopy study

Beilstein Journal of Nanotechnology, 2011
Terthiophene (3T) molecules adsorbed on herringbone (HB) reconstructed Au(111) surfaces in the low coverage regime were investigated by means of low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) under ultra-high vacuum conditions.

Nanobody‐Conjugated Theranostic Prodrug Targeting αvβ3 Integrin Enables Precision Cancer Therapy With Real‐Time Imaging

Advanced Healthcare Materials, EarlyView.
The image shows a schematic form a nanobody‐conjugated theranostic prodrug (NBD) platform targeting tumor‐associated αvβ3 integrin. The NBD system integrates selective nanobody‐mediated tumor recognition, glutathione‐responsive disulfide cleavage for doxorubicin release, and aza‐BODIPY‐based near‐infrared fluorescence for real‐time imaging.

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

Advanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

A comprehensive model for chemical bioavailability and toxicity of organic chemicals based on first principles

Frontiers in Marine Science, 2014
Here, we present a novel model to predict the toxicity and bioavailability of polychlorinated biphenyls (PCBs) as model compounds based on a first principles approach targeting basic electronic characteristics. The predictive model is based on an initio

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.
