You might have heard of diffusiophoresis in which charged colloids move either up or down an ion concentration gradient. But what happens if there are two gradients, crossed at right angles with each other? For the past couple of years, @ipwilliams did experiments to find out 1/2

Enthusiastically starting a new @EPSRC Impact Acceleration project with @ipwilliams working in collaboration with Pulpex to develop #sustainable #packaging pulpex.com @FEPSInfo aligned with @SurreySustain

I'm excited to see my microscope image of a Star Polymer Thin-Film @PhysicsatSurrey @KeddieLab in the journal for the International Association of Physics Students (jIAPS) See: iaps.info/blog/2022/08/0…… ( @IAPS_physics Lumiere Photo competition)

Farewell to Dr Yuxiu (Phil) Chen as he heads off to Newcastle! We enjoyed a nice walk along the River Wey with a stop at a riverside pub. Phil pushed forward our research in #biocoatings on the @LeverhulmeTrust project. New publication on wastewater treatment to appear soon!🤞

Very proud to host @sa_almad today. An excellent presentation about excellent work.

Published today in @JChemPhys. @Sara66Chem, @KeddieLab, @rpsear and I explore the physical chemistry of manufacturing latex gloves: doi.org/10.1063/5.0097…

There's an exciting PhD position to work with me and Dr Andrea Rocco. We are interested in studying the effect of noise in model genetic networks. Please check it out! findaphd.com/phds/project/n…

Good news for @Solomon_Melides who successfully defended his thesis this morning! His examiners appreciated his great results on wetting of heterogeneous surfaces: printed fat dots on soluble maltodextrin films @ChemEngSurrey @PhysicsatSurrey Great Supervision by @MarcoRamaioli

@DrJamesHallett Likely because efficiency is at the 10^-5 scale…

@ipwilliams Why doesn’t my car have a colloidal clutch yet?

“New” preprint on the Arxiv today: arxiv.org/abs/2205.01474

There's an exciting Ph.D. opportunity co-supervised by me and @rpsear to understand the transmission of COVID-19. If you're interested in building model viral particles, please have a look at the link below! surrey.ac.uk/fees-and-fundi…

Congratulations, @sa_almad. It has been a pleasure to work with you for the last few years. I’m incredibly proud.

This feels a bit bizarre after two years of the plague

@LNER Thank you for the information and fast reply

@ipwilliams It will be, yes.

@LNER I have a ticket from Guildford to Edinburgh for Friday, including Kings X to Edinburgh on an LNER train. If I travel tomorrow instead, will my ticket be valid for the Guildford to London part of my journey on a non-LNER service?

A merry Christmas from the @PhysicsatSurrey Soft Matter Physics Group! The past year was challenging for everyone, but the Group worked together wonderfully to achieve much. Hoping that 2022 is even better.

@ProjectScreenUK Thank you very much

@ipwilliams we do offer our apologies for the delay, we can confirm your result has been released.

@ProjectScreenUK I am supposed to be flying to the USA tomorrow and have been waiting almost 7 hours for my observed lateral flow results from you. Results were promised in 3 hours.
