Experimental Details Materials Tetraethylorthosilicate (TEOS, 99%), cetyltrimethylammonium bromide (CTAB, >95%), (3-aminopropyl)triethoxysilane (APTES), hydrochloric acid (HCl, assay 37%), absolute ethanol (EtOH, >99.9%), fluorescein isothiocyanate (FITC), 1-Ethyl-3(3-dimethylaminopropyl)carbodiimide (EDC), N-Hydroxysuccinimide (NHS), catalase (from Aspergillus niger), phosphate buffered saline...

The aim of our study was to reveal the fungal degradation in historical monuments ancient city Teos. In antique Teos, which is estimated exist since protogeometric period, field studies have been carried out on exposed deterioration. As a result it observed that especially cauliflower-like black microcolonial fungi, caused alteration artifacts. These fungi found cause brown coloration, crater-s...

Recently, many nanomedical studies have been focused on magnetic nanoparticles (MNPs) because MNPs possess attractive properties for potential uses in imaging, drug delivery, and theranostics. MNPs must have optimized size as well as functionalized surface for such applications. However, careful cytotoxicity and genotoxicity assessments to ensure the biocompatibility and biosafety of MNPs are e...

Development of optical biosensors is an active area of research in the field of medical technology. Sol-gel matrices made from alkoxide silicates, tetraethyl orthosilicate (TEOS) appear to be suitable glassy host matrix for the sensing system. However, the major problem in the TEOS based sol-gel matrices is stability. So it is important to study dopant-matrix interaction as a function of time. ...

Context. Heartbeat stars are eccentric binaries that exhibit a characteristic shape of brightness changes close to the periastron passage, primarily caused by variable tidal distortion components. Variable potential can drive tidally excited oscillations (TEOs), which usually gravity modes. Studies heartbeat and TEOs open up new possibilities for probing interiors massive stars. There only few ...
