Effect of morphology and temperature treatment control on the photocatalytic and photoluminescence properties of SrWO4 crystals
This work reports the combined effect of the morphology and crystallization degree of the strontium tungstate (SrWO4) scheelite structure on its photocatalytic and photoluminescence properties. The difference in ...

Open AccessWavelength and orientation dependent capture of light by diatom frustule nanostructures
The ecological success of diatoms is emphasized by regular blooms of many different species in all aquatic systems, but the reason behind their success is not fully understood. A special feature of the diatom ...

Open AccessNano-architecture of gustatory chemosensory bristles and trachea in Drosophila wings
In the Drosophila wing anterior margin, the dendrites of gustatory neurons occupy the interior of thin and long bristles that present tiny pores at their extremities. Many attempts to measure ligand-evoked curren...

Open AccessRaman scattering of linear chains of strongly coupled Ag nanoparticles on SWCNTs
We compare the Raman scattering properties of hybrid nanostructures consisting of Ag nanoparticles (NPs) in disordered and aligned arrangements on single-walled carbon nanotubes (SWCNTs) as a result of chemica...

Open AccessQuenching ilmenite with a high-temperature and high-pressure phase using super-high-energy ball milling
The mass production of highly dense oxides with high-temperature and high-pressure phases allows us to discover functional properties that have never been developed. To date, the quenching of highly dense mate...

Open AccessLight- induced electron transfer and ATP synthesis in a carotene synthesizing insect
A singular adaptive phenotype of a parthenogenetic insect species (Acyrthosiphon pisum) was selected in cold conditions and is characterized by a remarkable apparition of a greenish colour. The aphid pigments inv...

Self-Assembly and Raman Spectroscopy of Additive Coated Nanocrystals
Copper oxalate 1 µm-sized nanocrystalline assemblies with several shapes (cushions, lenses, drilled cushions, and square rods) have been obtained by aqueous precipitation without additive, with glycerol, with ...
