Madhavi Krishnan is a British chemist who is Professor of Physical Chemistry at the University of Oxford. Krishnan invented an electrostatic fluidic trap which permits the spatial control and manipulation of nanoscale materials. These traps can permit the sensitive detection of biomarkers of disease, allowing for early diagnosis.
Krishnan earned her undergraduate degree in Industrial Biotechnology at Anna University in Chennai. She moved to the United States for her graduate studies, where she joined the University of Michigan at Ann Arbor to work on genetic testing. Krishnan was an Alexander von Humboldt Foundation Fellow at TU Dresden, where she developed new techniques to trap colloidal nanoparticles and stretch DNA. [1] In 2008 she was awarded a Marie Curie Fellowship and moved to ETH Zurich. [2] She was a visiting scholar at the Harvard John A. Paulson School of Engineering and Applied Sciences. [3]
In 2012 Krishnan was appointed an Assistant Professor of Physical Chemistry at ETH Zurich, where she was eventually made a Swiss National Science Foundation Chair. She moved to the University of Oxford in 2018, where she was made an Associate Professor of Physical Chemistry. [4]
Krishnan investigates single-molecule imaging, making use of electrostatic fluid traps to suspend nanoscale materials. [5] Traditionally, molecular traps need external fields (for example, ion traps and optical tweezers), which can perturb the systems that are under investigation. [6] Investigating molecules in a field-free, electrostatic trap permits the non-destructive analysis of molecules in fluids at room temperature. [6] Studying molecules in this way allows for unparalleled opportunity to understand molecular size and charge. [6]
In September 2023 Krishnan was awarded a Title of Distinction of Professor of Physical Chemistry by the University of Oxford. [7]
Gilbert Newton Lewis was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley. Lewis was best known for his discovery of the covalent bond and his concept of electron pairs; his Lewis dot structures and other contributions to valence bond theory have shaped modern theories of chemical bonding. Lewis successfully contributed to chemical thermodynamics, photochemistry, and isotope separation, and is also known for his concept of acids and bases. Lewis also researched on relativity and quantum physics, and in 1926 he coined the term "photon" for the smallest unit of radiant energy.
Walther Hermann Nernst was a German physicist and physical chemist known for his work in thermodynamics, physical chemistry, electrochemistry, and solid-state physics. His formulation of the Nernst heat theorem helped pave the way for the third law of thermodynamics, for which he won the 1920 Nobel Prize in Chemistry. He is also known for developing the Nernst equation in 1887.
Brownian motors are nanoscale or molecular machines that use chemical reactions to generate directed motion in space. The theory behind Brownian motors relies on the phenomenon of Brownian motion, random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid.
Soft matter or soft condensed matter is a subfield of condensed matter comprising a variety of physical systems that are deformed or structurally altered by thermal or mechanical stress of the magnitude of thermal fluctuations. These materials share an important common feature in that predominant physical behaviors occur at an energy scale comparable with room temperature thermal energy, and that entropy is considered the dominant factor. At these temperatures, quantum aspects are generally unimportant. Soft materials include liquids, colloids, polymers, foams, gels, granular materials, liquid crystals, flesh, and a number of biomaterials. When soft materials interact favorably with surfaces, they become squashed without an external compressive force. Pierre-Gilles de Gennes, who has been called the "founding father of soft matter," received the Nobel Prize in Physics in 1991 for discovering that methods developed for studying order phenomena in simple systems can be generalized to the more complex cases found in soft matter, in particular, to the behaviors of liquid crystals and polymers.
Electrohydrodynamics (EHD), also known as electro-fluid-dynamics (EFD) or electrokinetics, is the study of the dynamics of electrically charged fluids. It is the study of the motions of ionized particles or molecules and their interactions with electric fields and the surrounding fluid. The term may be considered to be synonymous with the rather elaborate electrostrictive hydrodynamics. ESHD covers the following types of particle and fluid transport mechanisms: electrophoresis, electrokinesis, dielectrophoresis, electro-osmosis, and electrorotation. In general, the phenomena relate to the direct conversion of electrical energy into kinetic energy, and vice versa.
Armand Paul Alivisatos is an American etymologist, chemist and academic administrator who has served as the 14th president of the University of Chicago since September 2021. He is a pioneer in nanomaterials development and an authority on the fabrication of nanocrystals and their use in biomedical and renewable energy applications. He was ranked fifth among the world's top 100 chemists for the period 2000–2010 in the list released by Thomson Reuters.
Leroy "Lee" CroninFRSE FRSC is the Regius Chair of Chemistry in the School of Chemistry at the University of Glasgow. He was elected to the Fellowship of the Royal Society of Edinburgh, the Royal Society of Chemistry, and appointed to the Regius Chair of Chemistry in 2013. He was previously the Gardiner Chair, appointed April 2009.
Nanofluidics is the study of the behavior, manipulation, and control of fluids that are confined to structures of nanometer characteristic dimensions. Fluids confined in these structures exhibit physical behaviors not observed in larger structures, such as those of micrometer dimensions and above, because the characteristic physical scaling lengths of the fluid, very closely coincide with the dimensions of the nanostructure itself.
The Corday–Morgan Medal and Prize is awarded by the Royal Society of Chemistry for the most meritorious contributions to experimental chemistry, including computer simulation. The prize was established by chemist Gilbert Morgan, who named it after his father Thomas Morgan and his mother Mary-Louise Corday. From the award's inception in 1949 until 1980 it was awarded by the Chemical Society. Up to three prizes are awarded annually.
Molecular propeller is a molecule that can propel fluids when rotated, due to its special shape that is designed in analogy to macroscopic propellers: it has several molecular-scale blades attached at a certain pitch angle around the circumference of a shaft, aligned along the rotational axis.
