Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

A conceptual model for analyzing the stability condition and regime transition in bubble columns

, 2010
The abrupt change on the curve of gas holdup vs. superficial gas velocity calculated from the dual-bubble-size (DBS) model was physically interpreted as a shift from the homogeneous and transition regimes to the heterogeneous regime for bubble columns in

On the reliability of an optical fibre probe in bubble column under industrial relevant operating conditions [PDF]

, 2007
When bubble columns are operated under industrial relevant conditions (high gas and liquid flow rates, large bubbles and vortices,. . .), local data, and especially bubble size values, are difficult to obtain.

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Experimental study of bubble-drag interaction in a Taylor-Couette flow [PDF]

, 2013
This study is an experimental investigation of the interactions between the bubbles, the coherent motion and the viscous drag in a Taylor Couette flow, for the outer cylinder at rest. The cylinder radius ratio is 0.9.

Heat Transfer Between Gas and Liquid in a Bubble Column

Chemical Engineering Transactions, 2017
Multiphase contactors, e.g. bubble columns, are often used in operations accompanied by heat transfer between the phases. Literature studies have divided heat transfer measurements in two- and three-phase systems into: (i) estimations of bed-to-wall heat
