Glass samples have been processed by a single-step self-masking RIE (Reactive Ion Etching) process to obtain random subwavelength structures (SWSs), which mimic anti-reflective and anti-soiling patterns present in nature. The SWSs fabricated on glass provide an excellent broadband omnidirectional (AR) property (¡1% absolute reflectance) the spectral region (300–1200) nm due graded refractive index that these SWS produce air–glass interface, reducing reflectance.

Although localized surface plasmon resonance (LSPR) transducers can be optically interrogated without the need of light couplers, normally they tailor-made optical assemblies for signal monitoring. This fact limits application LSPR biosensors in laboratories due to lack specific setups. If commercial equipment like common spectrophotometers were suitable interrogation, technology could applied more often detection applications.

The increase in the operating temperature decreases efficiency and lifetime of photovoltaic (PV) systems. Radiative cooling effect offers a promising solution to passively reduce PV modules using atmospheric window (AW). Glass is well‐known material used as front cover modules. It presents fairly good emissivity AW although low‐absorption resonance at 9–10 μm its overall emissivity, hampering radiative capacity. This can be reduced by tailoring glass surface. Herein, samples are...

Superoxide dismutase enzymes (SODs) are an essential part of the first line cellular defense system against free radicals species. They catalyze dismutation superoxide into oxygen and hydrogen peroxide. Although several studies have examined attachment dismutases to nanoparticles nanostructures, never has been used a member Fe/MnSOD family. In this study, behavior plant origin FeSOD enzyme on three different nanopatterned surfaces was investigated as function covalent electrostatic binding....

We propose and experimentally demonstrate a novel method to fabricate subwavelength silica nanocone arrays with high aspect ratio (~7) for multifunctional surfaces having anti-reflective, self-cleaning, anti-fogging properties.
Tapered nanostructures with high aspect ratio were fabricated using high-throughput nanoimprint process. The replicated have axially increasing effective refractive index, which enhances the optical transmission over a wide range of wavelengths and incident angles.
Summary form only given. Spectrometers are widely used for scientific experiments in all different fields and real-time monitoring. In several setups it is necessary to measure a spectrum at positions over time [1], but with most spectrometers possible one time. For measuring two or more spectra simultaneously, which increases costs. the scope of EnviGuard project we have developed multichannel optical interrogator based on an integral field spectrometer that can capture up 12 channels parallel.
