'Dancing' holes in droplets submerged in water-ethanol mixtures

03-Jul-2018

Researchers from Tokyo Metropolitan University have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This curious, complex phenomenon is driven by an interplay between how ionic liquids dissolve, and how the boundary ...

MOFs provide a better way to remove water from gas

22-May-2017

The conventional view that metal-organic frameworks (MOFs) cannot be stable in water has been overturned by the development of an MOF that can selectively and effectively adsorb water to dry gas streams. "The achievement of energy efficient dehydration by our MOF is revolutionary," said Professor ...

Printed 'coffee rings' avoided with nanofibers

Cellulose nanofibers can help particles in ink and printed electronics disperse evenly

12-May-2017

Drying is an important part of printing words and electronics. Particles suspended in liquid are applied to a surface and the liquid evaporates leaving the particles behind. Many times, the particles dry unevenly because of the so-called 'coffee ring effect'. Much like when spilled coffee dries ...

Cellulose from wood can be printed in 3D

19-Jun-2015

A group of researchers at Chalmers University of Technology have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3D-bioprinter. They also added carbon nanotubes to create electrically conductive material. The effect is that ...

Spray drying the precision particle under the virtual magnifying glass

11-May-2015

Spray drying is a common manufacturing process, used in the production of ceramic granulate for technical components or dental prostheses as well as dissolvable medicinal substances, food additives and in the processing of milk into powder. Using computer simulation methodology developed by ...

New knowledge about permafrost improving climate models

30-Jul-2013

New research findings from the Centre for Permafrost (CENPERM) at the Department of Geosciences and Natural Resource Management, University of Copenhagen, document that permafrost during thawing may result in a substantial release of carbon dioxide into the atmosphere and that the future water ...

Producing hydrogen from wet biomass

FAU researchers co-ordinate EU research project for improving sustainability in energy production

13-Feb-2013

Renewable energy sources – such as hydrogen from wind power – are an important step towards reducing greenhouse gases and protecting our climate. Hydrogen can be produced sustainably using other sources than just wind power: the European research project SusFuelCat aims to improve the process of ...

Scotch tape finds new use as grasping 'smart material'

26-Nov-2012

Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material." Researchers used a laser to form slender half-centimeter-long fingers out of the tape. When exposed to water, the four wispy fingers morph ...

CFD collaboration between GEA Niro and DTU

Building a better spray dryer

08-Aug-2011

GEA Niro is working hand-in-hand with the Technical University of Denmark (DTU), to simulate the fluid dynamics that take place within a full-sized spray dryer. This is done using a scaled down model with water instead of air. The process allows experiments to be performed at a laboratory level ...
