The chemical and structural characteristics of solution-processed polymer with intrinsic microporosity (PIM) based on 9, 9-bis (4-hydroxyphenyl) fluorene (BHPF) film is investigated. A fully flexible transparent PIM exhibiting uniform high transmittance more than 90% within the visible light range demonstrated. stability further demonstrated relatively stable coefficient thermal expansion (CTE)...

The performance of glassy carbon (GCE) and graphite pencil electrodes (PGE) modified with multiwalled carbon nanotubes (CNTs) are compared, based on the direct electrochemical detection of nucleic acids. This is accomplished by monitoring the differential pulse voltammetry changes of the guanine signal. CNT-modified PGE compares favorably to that of the commonly used CNT-modified GCE owing to t...

Bragg gratings in etched polymer fibres and their unique properties and characteristics are discussed in this paper. Due to the change in material and mechanical properties of the polymer fibre through etching, Bragg gratings inscribed in such fibres show high reflectivity and enhanced intrinsic sensitivity towards strain, temperature, and pressure. The short-term and long-term stability of the...

Locally linear embedding is an effective nonlinear dimensionality reduction method for exploring the intrinsic characteristics of high dimensional data. This paper proposes a new manifold learning method, which is based on locally linear embedding and growing neural gas and is termed growing locally linear embedding (GLLE). GLLE overcomes the major limitations of the original locally linear emb...

Face is a human biometric attribute that can be used to establish the identity of a person. A face-based biometric system operates by capturing probe face samples and comparing them against gallery face templates. The intrinsic characteristics of captured face samples determine their effectiveness for face authentication. Face sample quality is a measurement of these intrinsic characteristics. ...

The aim of this work was to study the properties of the carboxylated polyelectrolyte obtained from guar gum. The C-6 alcohol functions of galactose units side chains were oxidized first by GO-ase to aldehyde groups and then to carboxylic groups by halogen oxidation. The enzymic oxidation step was followed by the Dische method, by viscosity and light scattering measurements. With regard to previ...
