Potentiostats are used extensively in electrochemistry to control and measure three electrode systems. Unfortunately, up until now this ubiquity has not resulted in potentiostats becoming cheaper or more accessible.
The new Ossila Potentiostat has been designed to help electrochemists perform cyclic voltammetry for less. The complete system includes cyclic voltammetry software, an electrochemical cell, and everything you need to start taking measurements.

Synthesising high quality quantum dots (QDs) can be a complex process.
During the original development of all-inorganic perovskite quantum dots, several synthetic routes were attempted in order to find a process that can reliably produce stable and defect resistant dots. Two major routes to the synthesis have now been developed: room temperate synthesis and synthesis by hot injection.

The discovery of ITIC and the subsequent boom in the use of non-fullerene electron acceptors in organic photovoltaic solar cells (OPVs) has resulted in rapid improvements in device power conversion efficiencies (PCEs).

Over the last two decades, quantum dots have elicited a considerable amount of excitement and attention from both research scientists and the media. When Sony launched their XBR line of televisions in 2013, quantum dots successfully moved from pure research into the commercial sphere. Despite this, there are still some barriers to overcome before we can expect to see widespread adoption of quantum dot-based products.

A great deal of focus has been given to non-fullerene acceptors (NFAs) in recent years, primarily around the research and development of bulk-heterojunction organic solar cells (OSCs). To a large extent they have taken the spotlight in this area away from fullerene derivatives like Phenyl-C81-Butyric Acid Methyl Esters (PCBMs).

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. PDMS-based transfer offers a fast and convenient way of depositing monolayer flakes of 2D materials onto virtually any substrate and, unlike other methods, does not require the use of wet chemistry.

We are absolutely thrilled to announce that an Ossila student employee, Oluchi Emenike, has won a Regional award for Student Employee of the Year (SEOTY) in the Commercial Impact category. This is the third time that one of our student employees has won a SEOTY award! Read about our previous SEOTY award-winning students.
The SEOTY awards have been held annually in the UK since 2002. As the UK’s largest student awards, they honour the extraordinary contributions and accomplishments of students who have flourished in combining their academic and part-time work duties.

Surface energy is a material property that can be used to explain why solutions wet differently on different surfaces. This is important for almost any solution processing technique. Values of surface energy can be calculated using contact angle measurements, allowing for easier optimisation of wetting. In the latest guide by...

Spin coating is a great technique to easily deposit thin films, but is easier for some materials than others. Solutions with poor solubility, or those that are very volatile/viscous can cause difficulties when spin coating - especially if they don’t wet well to the substrate. This means that non-uniform or...

As part of our continuous mission to enable more scientific research, we are happy to announce that several of our OPV & OLED substrates will now have permanent price reductions. Due to increased support and demand from our customers, we have been able to reduce costs by scaling up our manufacturing and production processes - thus allowing us to provide you prices that are even more affordable!
The following substrates (100 pieces) will now be priced at £199 (previously £425):
- S101: 6-Pixel ITO Glass OLED Substrates (Pixelated Anode)
- S171: 6-Pixel ITO Glass Substrates (Pixelated Cathode)
- S211: 8-Pixel ITO Glass Photovoltaic Substrates
In addition, our ITO substrate packs have also had a massive price reduction and are now £279 (previously £500).

Spin coating is a simple and straightforward thin-film deposition technique. As such, it is a great technique for beginners due to its relatively low barrier-to-entry. However, to become highly skilled at spin coating, it is beneficial to understand how the background physics involved (in terms of physical factors and solution properties)...

A material's properties are not only determined by what it is made of - the size of a material can also affect how it behaves. When reduced down to nanoscale form, certain materials will display properties that are different to what they show in their bulk form.

Earlier this week, we published a guide on the factors that influence the degradation of perovskite solar cells. As a follow-up to it, we now have a guide on several methods that have been found to help improve perovskite solar cell stability and durability. These methods can also be divided...

In the field of photovoltaics, it is common knowledge that perovskite solar cell stability and durability still has room for improvement. Although recent studies have shown promising advancements, perovskite solar cells still do not reach the standards defined by the International Electrotechnical Commision (performing well under non-lab conditions, and withstanding...

Molybdenum disulfide (MoS2) is an inorganic compound that is made up of molybdenum and sulfur. Oxygen and dilute acids do not have any effect on it, as it is a fairly unreactive compound. It is a member of the group of materials called 'Transition metal dichalcogenides' (TMDCs). A key characteristic shared...
