Rachel Claire Evans FRSC FIMMM FLSW is a Welsh chemist based at the University of Cambridge and a fellow of Jesus College, Cambridge. [1] She works on photoactive polymer-hybrid materials for solar devices, including organic photovoltaics and stimuli-responsive membranes. [2]
Evans grew up in South Wales. [3] She studied at Swansea University, earning a Master of Chemistry (MChem) degree in 2002. [4] [5] During her Masters, she completed an International Association for the Exchange of Students for Technical Experience (IASTE) fellowship at Lonza Group. [3] She returned to Swansea University for her PhD, investigating on light-emitting materials for display technologies. [6] [4]
After her PhD, Evans spent a year at the University of Aveiro. [4] She was subsequently awarded a Marie Curie Fellowship at the University of Paris [4] where she worked as a postdoc on fluorescence of soft materials. [4] Evans left Paris to join the University of Coimbra as a Fundação para a Ciência e Tecnologia postdoctoral fellow. She moved to Trinity College Dublin in 2009, where she was a lecturer in Physical Chemistry. Her research was funded by Science Foundation Ireland and Enterprise Ireland. [7] She delivered the 2011 Royal Society of Chemistry Schools lecture on the Chemistry of Light. [8] In 2013 she published the textbook Applied Photochemistry with Springer Publishing. [9] They explored self-assembly of conjugated polyelectrolyte–polyoxometalate networks, with dimensions controlled by the polymer chain length and steric charge distribution. [10] [11] The self-assembly of these lumophores can be used to tune the optical and electronic properties. [12] To understand the morphology of these films and inform the design of performance nanostructured devices, her group use small-angle scattering, spectroscopy and microscopy. [13] [14] Small-angle scattering allows her to study the microstructure of hybrid materials at the near atomic scale. [15] Their conjugated polyelectrolyte work was featured in the ChemComm Emerging Investigators issue. [16] She also worked on oxygen sensitive printable ink sensors. [17]
Evans has explored polymer-hybrid materials for luminescent solar concentrators. [18] By controlling the placement and orientation of the lumophore, she showed that it is possible to limit light lost by reabsorption. [19] [20] She minimises waveguiding losses by designing materials with high refractive indices. She demonstrated that perylene carboxdiimide-bridged triethoxysilane can be covalently grafted to siloxane hybrids. [18] Her work was featured in the Journal of Materials Chemistry C Emerging Investigators Issue in 2016. [21] She also develops encapsulation techniques to improve device lifetime. [22] She was made an associate professor in 2016. She collaborated extensively with the University of Montpellier as part of a French-Irish collaboration. [23]
Evans was appointed a lecturer at the University of Cambridge in 2017 [3] and a fellow of Jesus College, Cambridge. [4] Her group explore soft materials that are responsive to stimuli, nanostructured inks and hybrid nanoparticles. [24] The soft materials respond to light, using photoresponsive surfactants that include an azobenzene group. [25] She was appointed chair of the Royal Society of Chemistry Photophysics and Photochemistry Group in 2017. [26]
She founded Senoptica Technologies [27] in 2018 and is the chief scientific officer (CSO) working on optical sensors developed in Evans' lab. [28] Senoptica Technologies detect defective modified atmosphere packaging, changing colour to alert the consumer to the amount of oxygen in the pack. [29]

Trinity College, officially The College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, is the sole constituent college of the University of Dublin, a research university in Dublin, Ireland. Queen Elizabeth I founded the college in 1592 as "the mother of a university" that was modelled after the collegiate universities of Oxford and Cambridge, but unlike these affiliated institutions, only one college was ever established; as such, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes.
Jing Li is a professor at Rutgers University. She and her team are engaged in solid-state, inorganic and inorganic-organic hybrid materials research. Her current research focuses on designing and developing new materials for applications in the field of renewable and sustainable energy.

Nicholas A. Kotov is the Irving Langmuir Distinguished Professor of Chemical Sciences and Engineering at the University of Michigan in Ann Arbor, MI, USA. Prof. Nicholas Kotov demonstrated that the ability to self-organize into complex structures is the unifying property of all inorganic nanostructures. He has developed a family of bioinspired composite materials with a wide spectrum of properties that were previously unattainable in classical materials. These composite biomimetic materials are exemplified by his nacre-like ultrastrong yet transparent composites, enamel-like, stiff yet vibration-isolating composites, and cartilage-like membranes with both high strength and ion conductance.
