Cellulose White Pigments – A Sustainable Replacement to TiO2 for Health Sensitive and Industrial Applications?

A proprietary process with low-to-zero CO2 emissions has been developed, and scaled up, by Seprify AG to produce pure cellulose microparticles. At a specific size these microparticles have unique capabilities to scatter light thereby allowing it to be very efficient white pigments. As such, cellulose white pigments (CWP) can be an excellent sustainable, renewable, and… Read more »

Superhydrophobic Coatings and Coatings that Harvest Energy

Challenges around sustainability, energy-efficiency, robustness, etc. hinder the practical use of superhydrophobic surfaces and liquid-repellent coatings in general. Here we will present new insights from interfacial nanoengineering alongside their promise to address the challenges in healthcare and the net zero aspirations in infrastructure resilience, built environment and transport sectors. For example, performance of emergent coatings… Read more »

The Future of UK Chemical Regulation

Elaine’s presentation covers some of the issues and challenges faced in recent years by the UK Chemical industry.  With all the uncertainty in UK chemical regulation, Elaine will look at what may potentially be coming in the future and how business can plan for this.

Antibacterial and Antifungal Action of Surfaces and Coatings are Dependent on the Surrounding Environmental Conditions and Deposition Mechanics

Many antimicrobial surfaces and coatings are capable of passing standardised test methods and so are being labelled as antimicrobial but are ineffective at point of use. Current common standardised test methods (e.g. ISO22196) specify environmental conditions unlikely to be found in an end-use scenario, particularly relative humidity that is kept artificially high (>90 %). This… Read more »

The Development of Sustainable Paint for Coil Coated Steel

The use of organic coatings on coil coated steel is widespread among the construction, automotive industries and for use in domestic appliances. Almost all commercially available protective organic coatings are derived from fossil fuel origins. Increased environmental awareness has driven the requirement for alternatives to fossil fuel-based paint chemistries. The main aim of this work… Read more »

Chemical Analysis of Surfaces and Coatings by X-ray Photoelectron Spectroscopy

The surface of a material is the key interface at which chemical reactions, degradation and wearing processes occur. X-ray photoelectron spectroscopy (XPS) is a powerful tool for examining the composition and chemistry of the surface, with the inherent surface specificity limiting the information gathered to the outermost 5-10 nm, thereby elucidating the chemical properties of… Read more »

Radiative Cooling Coatings and Coatings That Can Produce Electricity From Sunlight

Radiative cooling, the natural thermoregulation process responsible for maintaining the Earth’s temperature balance, is emerging as a sustainable, electricity-free solution to combat building overheating. In my talk, I will delve into the fundamentals of radiative cooling, showcase the latest advancements in radiative cooling coatings and paints, and explore the challenges and opportunities that lie ahead.
