Morphology and microstructure evolution of gold nanostructures in the limited volume porous matrices

The modern development of nanotechnology requires the discovery for simple approaches that ensure the controlled formation of functional nanostructures with a predetermined morphology. One of the simplest...

Molecular Scylla and Charybdis – Maneuvering between pH-Sensitivity and excited state localization in ruthenium bi(benz)imidazole complexes

Bi(benz)imidazoles (b(b)im) acting as N,N-chelates in ruthenium complexes represent a unique class of ligands. They do not harbor metal-to-ligand charge-transfer (MLCT) excited states in ruthenium polypyridyl...

Molecular characterisation of extended-spectrum ß-lactamase producing Escherichia coli in wild birds and cattle, Ibadan, Nigeria

Background: Antimicrobial resistance (AMR) is an increasing global health concern reducing options for therapy of infections and also for perioperative prophylaxis. Many Enterobacteriaceae cannot be treated...

Apparatus to Investigate Liquid Oxygen Droplet Combustion under Microgravity Conditions

To investigate the fundamentals of liquid oxygen droplet combustion in hydrogen under microgravity conditions, a drop tower apparatus has been developed. In a cryogenic combustion chamber cooled with liquid...

Organic linkage controls the photophysical properties of covalent photosensitizer-polyoxometalate hydrogen evolution dyads

Understanding the complex photophysics of covalent photosensitizer–catalyst (PS–CAT) dyads is the basis for advanced structure and reactivity design. Here, we compare the light-induced processes of...

3D Spacer Fabrics for Thermoelectric Textile Cooling and Energy Generation based on Aluminum doped Zinc Oxide

It is demonstrated that spacer fabrics made of polyester can be coated with Al-doped ZnO (AZO) as thermoelectric material and conductive silver as contact material to enable smart textiles. An atomic layer...

Tailored micro-optical freeform holograms for integrated complex beam shaping

Sediment budgeting of short-term backfilling processes – the erosional collapse of a Carolingian canal construction

Sediment budgeting concepts serve as quantification tool to decipher the erosion and accumulation processes within a catchment and help to understand these relocation processes through time. While sediment...

Polarization-Dependent Vibrational Shifts on Dielectric Substrates

The interaction of light with matter at surfaces of dielectrics strongly depends on polarization. Here, we present the first infrared spectroscopic evidence for significant polarization effects in the...

Regenerated Fibre Bragg Gratings: A Critical Assessment of more than 20 Years of Investigations

Regenerated fibre Bragg gratings are formed when specially pre-treated seed gratings are heated up to several hundred degrees centigrade. During this process, the fibre Bragg grating (FBG) reflectivity...
