Chemical Engineering of Polymer Dispersions
CHIMIA, 2001 The research activity on dispersed polymers – polymer particle size from tens of nanometers to hundreds of microns – carried out at ETH in our group is reviewed with a brief summary of the various projects currently in progress. These have been organized into two main categories: Polymer Reaction Engineering, where polymerization reaction and

Preparation of Ni–YSZ thin and thick films on metallic interconnects as cell supports. Applications as anode for SOFC [PDF]
, 2008 In this work, we propose the preparation of a duplex anodic layer composed of both a thin (100 nm) and a thick film (10 lm) with Ni–YSZ material. The support of this anode is a metallic substrate, which is the interconnect of the SOFC unit cell.

A review of the toxicity of chemical dispersants [PDF]
Reviews on Environmental Health, 2011 Chemical dispersants are a mixture of various surfactants and solvents. Most dispersants are proprietary, and the complete composition is not often public knowledge. Chemical dispersants used for the cleanup and containment of crude oil toxicity became a major concern after the 2010 Deepwater Horizon oil crisis in the Gulf of Mexico. During the crisis,

Chemical affinity and dispersibility of boron nitride nanotubes
Nanoscale Advances, 2020 The chemical affinity of purified boron nitride nanotubes (BNNTs) is measured in terms of Hansen solubility parameters, taking into account relative sedimentation time in various solvents. This improves predictions for the dispersion of BNNTs.

Superconducting HfO2-YBa2Cu3O7-δ nanocomposite films deposited using ink-jet printing of colloidal solutions [PDF]
, 2019 To reduce the fabrication costs while maximizing the superconducting and pinning properties of YBa2Cu3O7−δ (YBCO) nanocomposite films, the drop-on-demand ink-jet printing technique was used to deposit colloidal YBCO inks onto LaAlO3 substrates.

2017 State-of the Science of Dispersants and Dispersed Oil (DDO) in U.S. Arctic Waters: Physical Transport and Chemical Behavior [PDF]
, 2017 Chemical dispersants were employed on an unprecedented scale during the Deepwater Horizon oil spill in the Gulf of Mexico, and could be a response option should a large spill occur in Arctic waters. The use of dispersants in response to that spill raised

Influence of Succinimide Dispersants on Film Formation, Friction and Antiwear Properties of Zinc Dialkyl Dithiophosphate [PDF]
, 2012 ZDDP (zinc dialkyldithiophosphate) is arguably the most successful antiwear additive ever employed in crankcase engine lubricants. It was originally used as an antioxidant and shortly afterwards recognized for its antiwear and extreme pressure ...

Laboratory Evaluation Of Chemical Oil Dispersants [PDF]
International Oil Spill Conference Proceedings, 1969 Abstract This paper describes some of the methods which can be used to evaluate chemical oil dispersants in order to obtain some preliminary data related to their effectiveness as dispersants and problems that may result from their use. Most of the techniques are quite simple and can be done fairly rapidly in the laboratory.
