Light alkanes can be converted to more useful chemicals in noble metal coated monoliths at very short contact times. The short-contacttime reactor is described by detailed models for the flow field, chemistry, and their coupling. The partial oxidation of methane to synthesis gas in a rhodium coated monolith is studied numerically as an example. Keyword: reactor modelling, catalytic partial oxid...

We present the first use of digital microfluidic techniques to perform on-chip solid phase extraction (SPE). The material used for SPE was a porous polymer monolith with 12-carbon functionality (C12 PPM) which was photopolymerized on-chip and used to desalt a peptide sample prior to nano-electrospray ionization mass spectrometric analysis (nano-ESI-MS). We anticipate this technique may be usefu...

This year the task of the UvA Rescue Team is to break up the monolith architecture of the control architecture. On the one hand this will make the existing modules reusable by other researchers; on the other hand it opens the possibility to incorporate e cient modules from other research groups. A rst attempt will be to incorporate 3DTK The 3D Toolkit which provides methods and algorithms to pr...

The performance of stabilization/solidification(S/S) monoliths is vital for the long-term effectiveness potentially toxic-element-contaminated soil treatments, which arevulnerable to environmental conditions (e.g., strongly acidic or alkaline conditions). This study numerically investigated S/S monolith materials in erosive environments with pHs ranging from 2.65 10.00 over three years. It was ...

A chloropropyl-functionalized silica (CP-silica) hybrid monolithic column was synthesized within the confines of a capillary via the sol-gel process using tetramethoxysilane (TMOS) and (3-chloropropyl)-trimethoxysilane (CPTMS) as the precursors. The resulting CP-silica hybrid monolith inside the capillary showed homogeneous macroporous morphology and was well attached to the inner wall of the c...

The paper aims at simulating the closed-system dynamic leaching of a cement-based monolith containing lead with the numerical reactive transport code HYTEC in a 3D-cylindrical geometry. The model considers, simultaneously, the chemical evolution of pore water, the progression of mineralogical alteration fronts, and the concomitant release of elements from the S/S waste. In good agreement with t...

Boehmite nanomaterials have been researched for use in applications such as separation media, fillers resins, and catalyst support. This study investigates the relationship between structural density mechanical thermal performance of boehmite nanofiber-polymethylsilsesquioxane (PMSQ) composite aerogels. Tri-functional organosilicon alkoxide methyltrimethoxysilane (MTMS) was added to a nanofiber...

An Al-based Metal-Organic Framework (MOF) obtained from Li-ion battery wastes as an upcycled material has been shaped a hierarchically porous solid monolith. This original method is based on the stabilization of Pickering High Internal Phase Emulsion (HIPE) by MOF particles that conducts to formation monolith after polymerization aqueous continuous phase and elimination organic internal emulsio...
