Enhancing the supramolecular stability of monolayers by combining dipolar with amphiphilic motifs: a case of amphiphilic push–pull-thiazole

Equipping a thiazole dye with push and pull moieties adds dipolar intermolecular interactions and two hydrophilic anchors to a centrally anchored p-stacking and otherwise mono-amphiphilic dye. We show...

Theoretical principles of Raman spectroscopy

This contribution reports on the theoretical foundations of Raman spectroscopy. Since the discovery of the Raman effect in 1928, Raman spectroscopy with its linear and nonlinear variants has established...

Combined effect of Yb inversion and pump photons on photodarkening in Yb laser fibers: experiments and model considerations

For constant Yb inversion and increasing pump power in the fiber core, a strong acceleration of the photodarkening (PD) process and reduction of PD loss are observed. The PD parameters determined by fitting...

3D-Modelling of Charlemagne’s Summit Canal (Southern Germany)—Merging Remote Sensing and Geoarchaeological Subsurface Data

The Early Medieval Fossa Carolina is the first hydro-engineering construction that bridges the Central EuropeanWatershed. The canal was built in 792/793 AD on order of Charlemagne and should connect the...

Progress and development in structural and optoelectronic tunability of supramolecular nonbonded fullerene assemblies

Assembly of fullerenes utilizing self-organization at solvent/non-solvent interfaces or by introducing hydrophobic(philic) end-groups have yielded diverse molecularly-ordered structures. Taking advantage...

Investigating Light-Driven Hole Injection and Hydrogen Evolution Catalysis at Dye-Sensitized NiO Photocathodes

Dye-sensitized photoelectrochemical cells form an emerging technology for the large-scale storage of solar energy in the form of (solar) fuels because of the low cost and easy processing of their constitutive...

Staphylococcus aureus isolates associated with nasal colonization and environmental contamination in academic dental clinics

Microarray-based detection of resistance and virulence factors in commensal Escherichia coli from livestock and farmers in Egypt

The objective of our study was to provide a molecular analysis using DNA-microarray based assays of commensal E. coli populations from apparently healthy livestock and their attendants to assess the virulence...

Characteristics of methicillin-resistance Staphylococcus aureus from broiler farms in Germany are rather lineage – than source-specific

Methicillin-resistant Staphylococcus aureus (MRSA) are a major concern for public health, and broiler farms are a potential source of MRSA isolates. In this study, a total of 56 MRSA isolates from 15 broiler...

MRSA Strains among Nepalese Rhesus macaques (Macaca mulatta), their Environment

This study looked at 227 saliva samples from Rhesus macaques (Macaca mulatta) and 218 samples from the surrounding environments. From these samples, MRSA isolates were collected from Rhesus saliva samples...
