Multimode microbolometers for wavelength-selective infrared detection have been designed using a Genetic Algorithm and an electromagnetic model of the planar antenna. Wavelength selectivity can be varied by changing the distance to a tuning mirror, or by changing only lithographically drawn parameters, with bandwidth narrower than Fabry-Perot microbolometers. The design of a three color system ...

To increase selectivity and sensitivity of determination of nitromethane in the air a set of piezoelectric gas sensors is proposed. In order to increase the differences between the signals sensor responses have been preliminary processed in accordance with the known algorithms. To determine nitrometane in the air an artificial neural network is applied and its parameters have been investigated.

Considerable by-catch problems have occurred in the commercial beam trawl fishery targeted at deep water pink shrimp Sea of Marmara. In this study, grid systems were used to reduce untargeted catch and improve species' selectivity. By-catch reduction ratios trawls deployed with without compared by parallel hauling method. Selectivity values 20 mm bar spacing 24 mesh size cod-end also analyzed S...

A thin layer of a SU-8 submicrometer pattern produced by holographic lithography was directly used as the dry-etching mask in a chemically assisted ion-beam-etching system. With optimized etching parameters, etching selectivity of 7:1 was achieved together with a smooth vertical profile. As an application, a half-wavelength retardation plate for a 1.55-microm wavelength was produced and evaluated.

The composition of a polymeric potential-determining phase for ketoprofen selective electrode has been determined and the following basic electrode parameters were examined: measurement range, slope characteristic, limit of detection, response time, lifetime and selectivity coefficients in relation to some organic and inorganic anions. The electrode have been used for ketoprofen determination i...

A bi-enzymatic cascade for the redox-isomerisation of allylic alcohol is presented. Coupling of an alcohol dehydrogenase to an enoate reductase has been successfully applied in one pot for the isomerisation of an allylic alcohol to the corresponding ketone. Critical parameters for yield and selectivity have been investigated.

4-Hydroxyacetophenone monooxygenase from Pseudomonas fluorescens ACB was employed in the presence of a weak anion exchange resin to perform dynamic kinetic resolutions of racemic benzyl ketones with high conversions and good optical purities. Different parameters that affect to the efficiency of the enzymatic Baeyer-Villiger oxidation and racemisation were analyzed in order to optimize the acti...

A new high performance liquid chromatography (HPLC)-based method is proposed for the determination of vitamin E, free and in inclusion complexes with natural beta-cyclodextrin and its 2-hydroxy derivative. The method has been validated on the basis of the following parameters: specificity, selectivity, linearity, precision, range and recovery.

The application of reactivity parameters derived from density functional theory in a local sense, in particular the softness and Fukui function, to interpret and predict the mechanisms of various organic reactions has been discussed. Local softness is shown to be successful in determining the site-selectivity and regiochemistry and can be used as an alternative to the traditional frontier orbit...
