Formulation of inkjettable nanoparticle fluids: Automatic powder feeder in experimental fluid design for printed electronics

A research team of the VTT Technical Research Centre of Finland conducted a study to formulate a carbon-coated copper nanoparticle (Cu+CNT) fluid for printed electronic devices. To obtain the nanoparticles, the automatic and programmable powder dispenser was attached to the heating section of a quartz reactor to dispense copper chloride (CuCl) to the evaporation zone (750 - 800 °C) in presence of nitrogen flow. In the formulation step, the produced particles were mixed with water and co-solvents. Then, the deposition of formulated nanoparticle fluids was carried out to evaluate their conductive properties.

The notable attributes of the developed copper nanoparticle fluid are its easy processing, handling, and low cost compared to silver and gold; however, the material is not envisioned to replace the conventional printable fluids in devices that require high conductivity. The application of functional inks studied is in devices that require low conductivity, such as antistatic coatings, resistors and sensors.

Laborfermenter / Parallelreaktor für die technische Fermentation 

Im Fermenterlabor sind Laborfermenter als Parallelreaktor für die technische Fermentation im Aufbau. Ein Blick auf die Reaktorgefässe ist interessant: 

Die schnell und einfach austauschbaren Reaktorgefässe - für alle Volumenbereiche zwischen 35 ml und 6 Liter Kulturmedium!

[lambda-instruments]

Auf kostbarer Laborfläche in der technischen Mikrobiologie, sind auch Chemostat Fermentationen von 6 Liter Arbeitsvolumen möglich! 

Das Bild vom Chemostaten aus dem Fermenterlabor zeigt einen modularen Laborfermenter für sechs Liter Arbeitsvolumen. 

Wann macht ein modularer Laborfermenter in der technischen Mikrobiologie Sinn? 

Ihre Forschung hat klein anzufangen, und Sie rechnen damit, Ihre Versuche später auszubauen.

Ihre kostbare Laborfläche ist begrenzt, und Sie halten alles Überflüssige von der Stellfläche fern.

Ihre Versuchsziele sind breit gefächert,  und Sie passen Ihre Laborversuche Schritt für Schritt optimal an.

Barbier-type allylation of aldehydes with allylic bromide and tin(II) chloride in presence of potassium iodide and ammonium chloride in water. 

During the reaction tin(II) iodide forms what is visible from the color change of the reaction. Tin(II) iodide is a bight orange salt that is not really soluble in water in the presence of ammonium ions. 

The Barbier reaction is an organometallic reaction between an alkyl halide (chloride, bromide, iodide), a carbonyl group and a metal. The reaction can be performed using magnesium, aluminium, zinc, indium, tin, samarium, barium or their salts. The reaction product is a primary, secondary or tertiary alcohol. The reaction is similar to the Grignard reaction but the crucial difference is that the organometallic species in the Barbier reaction is generated in situ, whereas a Grignard reagent is prepared separately before addition of the carbonyl compound.

The Barbier reaction is named after Victor Grignard’s teacher Philippe Barbier.
