New Application Note: Contact Angle Measurements of Surface Wetting

Posted on Tue, Apr 03, 2018 by Ashley Wong

When a droplet spreads over a surface and creates a contact angle of below 90°, a phenomenon known as 'surface wetting' is said to have occurred. A Contact Angle Goniometer is the best equipment for taking surface wetting measurements, because wetting and contact angle are directly related. Ossila have just produced a new application note where the Ossila Contact...

New Guide Available: Sheet Resistance Measurements of Thin Films

Posted on Tue, Mar 13, 2018 by Ashley Wong

An important characteristic of various materials, sheet resistance (a.k.a. surface resistivity) quantifies the ability for electric charges to move along uniform thin films. Knowing the sheet resistance of a material allows you to calculate its resistivity and conductivity - and thus enables you to electrically characterise the material.   Schematic...

Now Available: High-performing Polymer Acceptors - PNDI(2HD)T & PNDI(2HD)2T

Posted on Tue, Mar 06, 2018 by Hunan Yi

Having achieved 10% power conversion efficiencies (PCE), all-polymer solar cells (all-PSCs) have been the subject of significant research interest in recent years. With p-type polymers as electron donors and n-type polymers as electron acceptors, all-PSCs have contributed to the rise of high thermal, mechanical and photochemical device stability - with the prospect of large-area production.

    Amruth's Slot-Die Secondment

    Posted on Tue, Feb 20, 2018 by Ashley Wong

    As an industrial partner in the EU-funded Excilight Innovative Training Network (ITN) Programme, Ossila recently hosted Amruth, who is an Excilight PhD student. Amruth was on secondment with us from November 2017, and primarily worked with our Slot-Die Coater. As his secondment with Ossila drew to a close earlier this month, we thought it would be great for him to share his experiences and some of his research findings with you!

    New Slot-Die Coating Guide Available: Troubleshooting Defects

    Posted on Thu, Jan 25, 2018 by Jon Griffin

    An extremely versatile deposition technique, slot-die coating is capable of being integrated into both roll-to-roll and sheet-to-sheet deposition systems. Slot-die coating's key advantage is its simple relationship between i) wet-film coating thickness, ii) the flow rate of solution, and iii) the speed of the coated substrate relative to the head. Moreover, it can achieve extremely uniform films across large areas - in the best cases with variation being less than 1% across several meters.

    A Guide to Sheet Resistance

    Posted on Fri, Dec 08, 2017 by Chris Bracher

    Sheet resistance is the electrical resistance along a thin conductive film. It is inherently linked to the resistivity and thickness of the material being tested, and the measurement can be used to characterise thin films. Whether you are new to the measurement or simply want a refresher on the topic...

    Solution Preparation, Made Easy

    Posted on Mon, Dec 04, 2017 by Jon Griffin

    Whether in workshops or our own labs, we've always understood and emphasised the importance of the little things. For example, take the simple pipette tip or syringe filter - these simple accessories are often overlooked in favour of other shiny new pieces of equipment. However, even the most advanced equipment in the world will fail to give you accurate results if the fundamental steps are not carried out properly. Therefore, a basic step like solution preparation is truly a vital part of conducting experiments.
