Metal Catalysts for the Electrochemical Reduction of CO2

The world by and large has adopted the The Paris Agreement, which commits any signing party to cut greenhouse emissions drastically and prevent global heating above 2 °C beyond pre-industrial levels. For this ambitious goal to be met, ratifying states need ...

Microfluidics of binary liquid mixtures with temperature-dependent miscibility

Esther Amstad, Stefan Guldin

Liquid-liquid microfluidic systems rely on the intricate control over the fluid properties of either miscible or immiscible mixtures. Herein, we report on the use of partially miscible binary liquid mixtures that lend their microfluidic properties from a h ...

Swelling-Induced Chain Stretching Enhances Hydrolytic Degrafting of Hydrophobic Polymer Brushes in Organic Media

Harm-Anton Klok, Jian Wang

Hydrophilic polymer brushes grown via surface‐initiated polymerization from silicon oxide surfaces can detach or degraft in aqueous media. Degrafting of these chain end‐tethered polymers is believed to involve hydrolysis of bonds at the polymer–substrate i ...

Ab Initio Molecular Dynamics Investigation of Molten Fe-Si-O in Earth's Core

James Badro

Silicon and oxygen are potential light elements in Earth's core because their stronger affinity to metal observed with increasing temperature posits that significant amounts of both can be incorporated into the core. It was proposed that an Fe-Si-O liquid ...

Working fluid charge reduction, part 1: CO2 fin-tube evaporator designed for light commercial appliances utilizing flow pattern based phenomenological prediction models

John Richard Thome, Jackson Braz Marcinichen

The present study focused on improving the thermal performance of CO2 evaporators while reducing their volume and thus significantly reducing the working fluid charge. To achieve this, the leading two-phase flow pattern and physically-based prediction mode ...

Solvent effects in catalysis: rational improvements of catalysts via manipulation of solvent interactions

Paul Joseph Dyson, Philip Gregory Jessop

In homogeneous catalysis, the main emphasis on improving catalyst performance (rate, yield and selectivity) is directed towards manipulation of the ligands. The steric and electronic effects of ligands are extremely well understood and the rational design ...

Working fluid charge reduction. Part II: Supercritical CO2 gas cooler designed for light commercial appliances

John Richard Thome, Jackson Braz Marcinichen

The present study focused on the thermal hydraulic performance improvement of a CO2 gas cooler with the principal goal of reducing its volume, and consequently the necessary charge of the working fluid. To achieve this compactness, the leading methods for ...

Fe-containing Hydrates and their Fate during Cement Hydration : Thermodynamic Data and Experimental Study

Belay Zeleke Dilnesa

Thermodynamic modeling is a versatile tool for predicting the chemical composition cement during the hydration of cement. The quality of the thermodynamic modeling depends directly on the quality and completeness of thermodynamic database used. One of the ...

Dynamics of fluid mixtures in nanospaces

A multicomponent extension of our recent theory of simple fluids [U. M. B. Marconi and S. Melchionna, J. Chem. Phys. 131, 014105 (2009)] is proposed to describe miscible and immiscible liquid mixtures under inhomogeneous, nonsteady conditions typical of co ...

Formation and study of single metal ion–phospholipid complexes in biphasic electrospray ionization mass spectrometry

Hubert Girault, Daniel Filipe Dos Santos Alves Jana, Anne-Clémence Corminboeuf, Manuel Alejandro Méndez Agudelo, Michel Prudent

Single metal ion-phospholipid complexes are observed in biphasic electrospray ionization mass spectrometry (BESI-MS) using a dual-channel microsprayer. Such a microsprayer makes it possible to put into contact two immiscible liquids within the Taylor cone. ...
