The work is devoted to the synthesis and characterization of gels based on monomers pentaerythritol triaacrylate (PETriA) 2,2 '-(ethylenedioxy)diethanethiol (EDODET) by thiol-ene "click" polymerization. properties obtained were investigated IR, Raman spectroscopy, mechanical analysis. Sol-gel analysis networks was carried out degradability investigated. results IR spectroscopy confirmed presenc...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

BACKGROUND Aluminum is considered to be a relatively safe metal for humans. However, there are some reports that aluminum can be toxic to humans and animals. In order to estimate the toxicity of aluminum with respect to humans, we measured the aluminum concentration in urine of aluminum-handling and non-handling workers and investigated the relationships between their urinary aluminum concentra...

The Aluminum Hypothesis, the idea that aluminum exposure is involved in the etiology of Alzheimer disease, dates back to a 1965 demonstration that aluminum causes neurofibrillary tangles in the brains of rabbits. Initially the focus of intensive research, the Aluminum Hypothesis has gradually been abandoned by most researchers. Yet, despite this current indifference, the Aluminum Hypothesis con...

Aluminum has been implicated in several neurodegenerative conditions including Alzheimer's disease. Because the mammalian olfactory system has an unusual capacity for the uptake and transneuronal spread of inhaled substances such as aluminum, whole cell recording techniques were used to examine the actions of aluminum on basic membrane properties and amino acid receptors on rat olfactory bulb m...

Nanoscale features as small as 65 ± 5 nm have been formed reproducibly by using 520nm femtosecond pulsed excitation of a 4,4'-bis(di-n-butylamino)biphenyl chromophore toinitiate crosslinking in a triacrylate blend. Dosimetry studies of the photoinducedpolymerization were performed on chromophores with sizable two-photon absorptioncross-sections at 520 and 730 nm. These studies s...

We report on a simple and effective process that allows direct imprinting of microand nanostructures on non-flat surfaces using flexible polymer stamps. Pattern imprinting was tried using a UV-curable polymer blend containing poly(propylene glycol) diacrylate, trimethylolpropane triacrylate and a photoinitiator. The UV-resist was dispensed manually on convex and concave surfaces of a glass lens...
