MICRA brings together researchers working across the field of inorganic chemistry. Attendees are expected to be at an early stage in their career. This includes early career academics, independent research fellows and experienced postdoctoral researchers.
All attendees are encouraged to give short presentations on their work in order to introduce themselves to the community and potentially inspire new collaborations. The meeting is a great opportunity to get to know the early career researchers across the UK working in inorganic chemistry.
In 2024, MICRA will be held at the University of Leicester from 9-11 September. Leicester has a strong history of inorganic chemistry and is a friendly city, bursting with heritage and culture.
Along with oral presentations from the delegates, we will also host plenary speakers from experienced members of the inorganic chemistry community. We will also hold a Q&A session to give advice and help answer those burning questions that early career researchers may have.
We study fundamental electrochemical problems through nanoscale science and technology. Our primary focus is on electrochemical energy conversion, but focus areas also include biosensors and bio-nanomaterials. Research in our lab is highly interdisciplinary and overlaps with material science, biochemistry, microbiology, biotechnology and analytical chemistry. Please see our lab website (www.ramasamy.uga.edu) page for more information.
We appreciate your financial support. Your gift is important to us and helps support critical opportunities for students and faculty alike, including lectures, travel support, and any number of educational events that augment the classroom experience. Click here to learn more about giving.
Kogularamanan "Rama" Suntharalingam has been selected by the Royal Society of Chemistry to receive the 2014 Dalton Young Researchers Award in Chemistry for his contributions to the design and development of new metallo-pharmaceuticals and to the understanding of their complex mechanisms of action.
Suntharalingam, who was born in 1986, is of Tamil origin and grew up in the U.K. He attended Imperial College London for his undergraduate studies, receiving a first-class MSci degree in chemistry in 2008. He continued his studies at Imperial College London and received a PhD in chemistry in 2012.
Under the mentorship of his PhD advisor, Ramon Vilar, Suntharalingam explored the interaction of metal complexes with quadruplex DNA. During that time, Suntharalingam published several high-impact papers in top-flight journals, and presented his findings at national and international conferences, including the "Dalton Transactions Younger Researchers Symposium" in 2011. Suntharalingam has also co-authored three book chapters, one as a single author.
Suntharalingam is currently a postdoc in Professor Stephen J. Lippard's research group in the Department of Chemistry. His current research combines facets of inorganic chemistry, nanotechnology, and molecular biology. Lippard refers to Suntharalingam as "a wonderfully creative addition to the laboratory."

Human manganese superoxide dismutase is an oxidoreductase that converts superoxide to molecular oxygen and hydrogen peroxide with proton-coupled electron transfers (PCETs), and has evolved to be highly product inhibited to limit the formation of hydrogen peroxide. Here, the authors use neutron diffraction and X-ray absorption spectroscopy of the product-bound, trivalent, and divalent states of the enzyme to identify the product-inhibited complex and propose a PCET mechanism.
Exploring the dual-emission mechanism in open-shell nanoclusters with doublet or quartet emissions remains challenging. Here, the authors reveal the origin of dual-quartet phosphorescent emission in the open-shell M1Ag13 (M = Pt, Pd) nanoclusters.
Despite the progression of Actinium-225 (225Ac) radiopharmaceuticals, there is still a limited understanding of Ac coordination chemistry due to its radioactivity, poor availability, and lack of stable isotopes. Here, the authors demonstrate a platform to characterize the solution and solid-state behavior of the longest-lived Ac isotope, 227Ac.
The authors report a Cu/Cu2Se-Cu2O heterojunction nanosheet array which show cases efficient CO2 reduction to ethanol using solar energy through a confluence of effects stemming from the catalyst heterostructure and including photothermal and confinement effects.
The authors fabricate ferroelectric freestanding hafnia membranes with metastable rhombohedral structure down to 1-nm-thick, highlighting the key role of the rhombohedral phase in the scale-free ferroelectricity in hafnia.
Long persistent luminescence materials often show monochromatic emission. Here, the authors fabricate a series of inorganic halide perovskites with time-dependent afterglow color and reverse excitation-dependent Janus-type luminescence.
Phosphanorcaradienes can serve as synthons for transient phosphinidene but the synthesis remains challenging. Here, the authors report a synthesis protocol for a phosphanorcaradiene, in which one of the benzene rings is intramolecularly dearomatized through attachment to the phosphorus atom.
Electron transfer in solids is a fundamental process in many functional nanomaterials. Here, the authors directly observe this process via x-ray crystallography for incorporating of electron-donor guest molecules in macrocyclic nanotube crystals.
7C-10C and 12C-carbolong complexes with planar ligand skeletons containing 7-10 and 12 carbon atoms have been previously reported but 11C-carbolong complexes with a planar carbon-chain ligand are elusive. Here, the authors prepare metallabenzyne-fused metallapentalenes and metallabenzene-fused metallapentalynes, both representing 11C-carbolong complexes with a planar carbon-chain ligand
The authors use femtosecond K-edge X-ray absorption spectroscopy to follow nuclear motion in a manganese-based tri-nuclear single-molecule magnet, and resolve changes in bond lengths on the order of hundreds of ngstrms and on sub-picosecond timescales.
CALF-20 is a water stable structure capable of selectively separating CO2 from flue gas. Here authors use a close feedback loop between theory and experiments to understand CO2/water adsorption and framework flexibility of CALF-20.
So far, only homoleptic N2 complexes of silicon have been reported under matrix-isolation conditions including but the activation of more inert nitrogen by silylenes remains challenging. Here the authors report on the activation of dinitrogen by silylenes under cryogenic conditions.
Hong et al. report 2D perovskite lateral homojunction consists of ordered and disordered phases, achieved by organic cation doping induced phase pinning, built upon which they develop tuneable optical properties under external stimuli and directional exciton diffusion in the homojunctions.
Bis(N-heterocyclic carbene)-borylene complexes are capable of capturing and functionalizing CO2, but stable single-site-boron-carbon dioxide adducts are rarely reported. Here, the authors report the synthesis of a stable borylene-CO2 complex as well as the functionalization of the captured CO2.
Icosahedral carboranes have long been considered to be aromatic but the extent of conjugation between these clusters and their substituents is still being debated. Here the authors demonstrate carboranes as conjugated bridges in optical functional chromophores.

Chemical reduction of alkali cations to their metals is extremely challenging. Here, the authors synthesized a series of redox-active borate anions stabilized by bipyridine ligands which can reduce lithium ions generating elemental lithium metal and borate radicals.
Many alkyl fluorides are readily available, but the synthetic applications trail behind the widely accepted utility of other halides. Here, the authors report a practical Csp3-F bond functionalization method that expands the currently restricted synthetic space of unactivated C(sp3)-F bonds, but also uses benzylic, propargylic and acyl fluorides.
Coordination-induced bond weakening (CIBW) by redox-active metals is used to weaken bonds in water and ammonia to facilitate proton-coupled electron transfer but achieving CIBW using aluminium as abundant metal is challenging. Here, the authors report a system that uses aluminum with a redox non-innocent ligand to achieve CIBW of O-H and N-H bonds.
