Surface modified microfibrillated cellulose‐poly(vinylidene fluoride) composites: β‐phase formation, viscoelastic and dielectric performance

Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Mohammed Arif Poothanari

The effect of silylation of microfibrillated cellulose (MFC) surfaces on β‐phase formation in poly(vinylidene difluoride) (PVDF) and the resulting viscoelastic and dielectric performance of MFC‐PVDF composites is investigated. Two different organosilanes, ...

A Two Step Postsynthetic Modification Strategy: Appending Short Chain Polyamines to Zn-NH2-BDC MOF for Enhanced CO2 Adsorption

Wendy Lee Queen, Jordi Espin Marti, Mehrdad Asgari, Olga Trukhina, Ilia Kochetygov, Anita Justin

Functionalizing metal–organic frameworks (MOFs) with amines is a commonly used strategy to enhance their performance in CO2 capture applications. As such, in this work, a two-step strategy to covalently functionalize NH2-containing MOFs with short chain po ...

Succinimidyl Carbonate-Based Amine-Reactive Polymer Brushes: Facile Fabrication of Functional Interfaces

Harm-Anton Klok

Polymeric coatings that can undergo effective functionalization with ligands and (bio)molecules necessary for intended applications are widely employed to engineer functional interfaces. Herein, amine-reactive polymer brushes are fabricated using a succini ...

Comparative assessment of advanced power generation and carbon sequestration plants on offshore petroleum platforms

On conventional offshore petroleum platforms, the combined heat and power production (CHP) currently depends on simple cycle gas turbine systems (SCGT) that operate at lower efficiency and increased environmental impact compared to modern onshore thermoele ...

In Silico Discovery of Covalent Organic Frameworks for Carbon Capture

Berend Smit, Daniele Ongari, Christoph Leopold Talirz, Aliaksandr Yakutovich, Johanna Maria Huck, Kathryn Suzanne Deeg, Daiane Damasceno Borges, Nakul Rampal

We screen a database of more than 69 000 hypothetical covalent organic frameworks (COFs) for carbon capture using parasitic energy as a metric. To compute CO2-framework interactions in molecular simulations, we develop a genetic algorithm to tune the charg ...

Selective Acceptorless Dehydrogenation of Primary Amines to Imines by Core-Shell Cobalt Nanoparticles

Paul Joseph Dyson, Zhaofu Fei, Xinjiang Cui, Matthias Beller

Core-shell nanocatalysts are attractive due to their versatility and stability. Here, we describe cobalt nanoparticles encapsulated within graphitic shells prepared via the pyrolysis of a cationic poly-ionic liquid (PIL) with a cobalt(II) chloride anion. T ...

Partial Hydrogenation of 2-Methyl-3-butyn-2-ol over Pd/ZnO: Effect of Reduction Temperature on Alloy Formation and Catalytic Response

Lioubov Kiwi, Fernando Cardenas Lizana

We have investigated the catalytic effect of the beta-phase PdZn alloy on selective gas-phase hydrogenation of 2-methyl-3-butyn-2-ol over Pd/ZnO using Pd/Al2O3 as a benchmark. Activation (in H-2) of Pd/ZnO to 973 K generated a beta-phase PdZn alloy (from X ...

Delineation of the Critical Parameters of Salt Catalysts in the N-Formylation of Amines with CO2

Paul Joseph Dyson, Martin Hulla, Dmitry Vasilyev

N-formylation of amines with CO2 is base-catalyzed and studies of salt catalysts reveal that the reaction is efficiently catalyzed by "free" floating anions of high basicity, as represented in the cover image. More information can be found in the Full Pape ...

Quantification of amine functional groups and their influence on OM/OC in the IMPROVE network

Satoshi Takahama

Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C = O, in atmospheric parti ...
