We introduce Gaussian Process Topic Models (GPTMs), a new family of topic models which can leverage a kernel among documents while extracting correlated topics. GPTMs can be considered a systematic generalization of the Correlated Topic Models (CTMs) using ideas from Gaussian Process (GP) based embedding. Since GPTMs work with both a topic covariance matrix and a document kernel matrix, learnin...

Nanocrystalline cellulose (NCC) was used as a modifier for waterborne polyurethane (WPU) to investigate the water and ethanol resistance of WPU-NCC composites. The NCC surface was modified with γ-glycidoxypropyltrimethoxysilane (GPTMS) and γammnonimpropylmethyldimethoxysilane (APMDS) to improve its compatibility with waterborne polyurethane (WPU), as indicated by the contact angle (CA). The cha...

The treatment of peripheral nerve injuries remains one of the greatest challenges of neurosurgery, as functional recover is rarely satisfactory in these patients. Recently, biodegradable nerve guides have shown great potential for enhancing nerve regeneration. A major advantage of these nerve guides is that no foreign material remains after the device has fulfilled its task, which spares a seco...

In the present work, a study was carried out to compare morphology and electrochemical properties of pure graphene-modified hybrid silica sol–gel coatings deposited on anodized AZ31B magnesium alloys. The precursor solution prepared using tetraethoxysilane (TEOS) 3-glycidoxypropyl-trimethoxysilane (GPTMS), with addition chemically modified graphene nanosheets (GN-chem). Homogeneous adherent wer...

This work reports the obtention of nanocompounds from epoxy resin (EP) with graphenes at three different oxidation degrees (GO1, GO2, and GO3), functionalized 3-glycidyloxypropyl trimethoxysilane (GPTMS), graphene concentrations (1%, 2%, 3%). The aim is to improve GO compatibility in EP obtain a nanocompound synergistic properties. Ultrasonic bath was used disperse GO, factor effective interact...

3-Glycidoxypropyltrimethoxysilan, also known as GPTMS, is a versatile organosilane compound that has gained significant attention in various fields. Its unique chemical structure, consisting of glycidoxy group and three methoxy groups attached to propyl chain, enables it exhibit exceptional reactivity compatibility with different materials. In the literature, extensive research been conducted u...

We report the formation and characterization of graphene dispersions in two organosilanes, 3-glycidoxypropyl trimethoxysilane (GPTMS) and phenyl triethoxysilane (PhTES) as new reactive solvents. The preparation method was mild and easy and does not produce any chemical modification. The dispersions, which exhibit the Tyndall effect, were characterized by TEM and Raman spectroscopy to confirm th...

In the current opinion, we would like to study adhesion of DNA and RNA−amphiphile complexes to non–modified glasses, glasses containing phenylboronic acid (PBA) attached via 3– glycidoxypropyltrimethoxysilane (GPTMS) [(PBA–GPTMS–glasses)] and glasses containing grafted dimethyllacrylamide–acrylamide phenylboronic acid (DMAA–AAPBA) copolymer (DMAA–AAPBA– glasses). We prepared glasses modified wi...

This paper describes the apatite deposition of chitosan-silicate porous hybrids derived from chitosan and γ-glycidoxypropyltrimethoxysilane (GPTMS) in alkaline phosphate solution. The preparation of porous hybrids with needle-like apatite on their surfaces is described. Following apatite deposition the porous hybrids maintained high porosity. The enzymatic degradation rate was low even after 6 ...
