Synthesis of Polymer in Supercritical Carbon Dioxide

open access: yesKobunshi, 2008
A conductive polyaniline thin film was successfully synthesized in a homogeneous supercritical carbon dioxide system. An AFM measurement revealed the flat surface of the obtained film in that system.

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Solvation Of Purine Alkaloids In Supercritical Co2 By Molecular Dynamics Simulations [PDF]

open access: yes, 2015
A molecular dynamics (MD) computer simulation study is presented for the solvation of purine alkaloids (caffeine, theophylline, and theobromine) in supercritical CO2 at 313 K and density in the range 0.117-0.94 g/cm3 using force fields that treat all ...

Gas Sensing With Aerogels: A Critical Review on Structure‐Property Correlations and Performance Optimization

open access: yesAdvanced Science, EarlyView.
With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, EarlyView.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).
