Surface deep profile synchrotron studies of mechanically modified top-down silicon nanowires array using ultrasoft X-ray absorption near edge structure spectroscopy

Atomic, electronic structure and composition of top-down metal-assisted wet-chemically etched silicon nanowires were studied by synchrotron radiation based X-ray absorption near edge structure technique....

Functional materials: making the world go round

Electronic and atomic structure studies of tin oxide layers using X-ray absorption near edge structure spectroscopy data modelling

The phase composition and local atomic and electronic structure of tin oxide layers have been studied by applying synchrotron X-ray absorption near edge structure spectroscopy. The inear combination analysis...

Light-sheet microscopy with isotropic, sub-micron resolution and solvent-independent large-scale imaging

We present cleared tissue Axially Swept Light-Sheet Microscopy (ctASLM), which achieves sub-micron isotropic resolution, high optical sectioning capability, and large field of view imaging (870×870 μm2)...

Compliance-current-modulated resistive switching with multi-level resistance states in single-crystalline LiNbO3 thin film

Resistive switching behavior of a ca. 600 nm thick single-crystalline LiNbO3 (LNO) film has been investigated after vacuum-annealing. Oxygen vacancies (OVs) were generated in the LNO thin film during the...

Two-Photon Induced CO-Releasing Molecules as Molecular Logic Systems in Solution, Polymers and Cells

Phototherapeutic applications of carbon monoxide(CO)-releasing molecules are limited because they require harmful ultraviolet (UV) and blue light for activation. We describe two-photon excitation with...

Design of Novel TiO2-SiO2 Core-Shell Helical Nanostructured Anti-Reflective Coatings on Cu(In,Ga)Se2 Solar Cells with Enhanced Power Conversion Efficiency†

Introducing an anti-reflective coating (ARC) is the last step of fabricating Cu(In,Ga)Se2 solar cells with enhanced photogenerated current by reducing the reflectance of visible light. The use of nanostructures...

Protein corona formation and its constitutional changes on magnetic nanoparticles in serum featuring a polydehydroalanine coating: effects of charge and incubation conditions

The inevitable formation of a protein corona upon contact of nanoparticles with different biological fluids is of great interest in the context of biomedical applications. It is well established that the...

Optical manipulation, beam-shaping and scanner-free bright-field and dark-field imaging via multimode optical fibre

We present a powerful approach towards full understanding of laser light propagation through multimode optical fibres and control of the light at the fibre output. Transmission of light within a multimode...

Single laser beam based passive optical sorter

We demonstrate experimentally a new method of sorting of colloidal particle suspension in wide single laser beam. The sorting is performed in a realization of a "tractor" beam a weakly focused laser beam...
