Phillip Geissler
Phillip L. Geissler (March 27, 1974 – July 17, 2022) was a theoretical chemist and the Aldo De Benedictis Distinguished Professor of Chemistry at UC Berkeley. Geissler contributed to the theory and understanding of water, which he described as "a famously unusual liquid”. He was particularly interested in collective fluctuations that dictated kinetics in aqueous solutions, solvation, and ion-specific effects. He examined the vibrational spectra of water and the dynamical trajectories of water models and simulated air–water interfaces. He further studied the statistical mechanics of biological polymers and heterogeneous materials; explored pathways and guiding principles for nanoscale self-assembly; and developed techniques of model and algorithm development. Education Geissler was born in 1974 in Ithaca, New York. He grew up in Charlottesville and in Richmond, Virginia, graduating from Douglas S. Freeman High School. Geissler attended Cornell University as an unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ithaca, New York
Ithaca is a city in the Finger Lakes region of New York (state), New York, United States. Situated on the southern shore of Cayuga Lake, Ithaca is the seat of Tompkins County, New York, Tompkins County and the largest community in the Ithaca metropolitan statistical area. It is named after the Greek island of Ithaca (island), Ithaca. A college town, Ithaca is home to Cornell University and Ithaca College. Nearby is Tompkins Cortland Community College (TC3). These three colleges bring thousands of students to the area, who increase Ithaca's seasonal population during the school year. As of 2020, the city's population was 32,108. History Early history Native Americans lived in this area for thousands of years. When reached by Europeans, this area was controlled by the Cayuga tribe of Indians, one of the Five Nations of the ''Haudenosaunee'' or Iroquois League. Society of Jesus, Jesuit missionaries from New France (Quebec) are said to have had a mission to convert the Cayug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanomaterials
* Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale). Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, thermo-physical or mechanical properties. Nanomaterials are slowly becoming commercialized and beginning to emerge as commodities. Definition In ISO/TS 80004, ''nanomaterial'' is defined as the "material with any external dimension in the nanoscale or having internal structure or surface structure in the nanoscale", with ''nanoscale'' defined as the "length range approximately from 1 nm to 100 nm". This includes both ''nano-objects'', which are discrete pieces of material, and ''nanostructured materials'', which have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Institute For Quantitative Biosciences
The California Institute for Quantitative Biosciences (QB3) is a nonprofit research and technology commercialization institute affiliated with three University of California campuses in the San Francisco Bay Area: Berkeley, San Francisco, and Santa Cruz. QB3's domain is the quantitative biosciences: areas of biology in which advances are chiefly made by scientists applying techniques from physics, chemistry, engineering, and computer science. History QB3 was founded in 2000 as one of four Governor Gray Davis Institutes for Science and Innovation (originally, California Institutes for Science and Innovation, or Cal ISIs). From a 2005 article written for the University of California Academic Senate: The Institutes were launched in 2000 as an ambitious statewide initiative to support research in fields that were recognized as critical to the economic growth of the state—biomedicine, bioengineering, nanosystems, telecommunications and information technology. Moreover, the Cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrence Berkeley National Laboratory
Lawrence Berkeley National Laboratory (LBNL), commonly referred to as the Berkeley Lab, is a United States national laboratory that is owned by, and conducts scientific research on behalf of, the United States Department of Energy. Located in the hills of Berkeley, California, the lab overlooks the campus of the University of California, Berkeley, and is managed by the University of California system. History 1931–1941 The laboratory was founded on August 26, 1931, by Ernest Lawrence, as the Radiation Laboratory of the University of California, Berkeley, associated with the Physics Department. It centered physics research around his new instrument, the cyclotron, a type of particle accelerator for which he was awarded the Nobel Prize in Physics in 1939. Throughout the 1930s, Lawrence pushed to create larger and larger machines for physics research, courting private philanthropists for funding. He was the first to develop a large team to build big projects to make discov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanoassembler
A molecular assembler, as defined by K. Eric Drexler, is a "proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision". A molecular assembler is a kind of molecular machine. Some biological molecules such as ribosomes fit this definition. This is because they receive instructions from messenger RNA and then assemble specific sequences of amino acids to construct protein molecules. However, the term "molecular assembler" usually refers to theoretical human-made devices. Beginning in 2007, the British Engineering and Physical Sciences Research Council has funded development of ribosome-like molecular assemblers. Clearly, molecular assemblers are possible in this limited sense. A technology roadmap project, led by the Battelle Memorial Institute and hosted by several U.S. National Laboratories has explored a range of atomically precise fabrication technologies, including both early-generation and longer-term prospects for progr ...

Adsorb
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a fluid (the ''absorbate'') is dissolved by or permeates a liquid or solid (the ''absorbent''). Adsorption is a ''surface phenomenon'', while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term ''sorption'' encompasses both processes, while ''desorption'' is the reverse of it. Like surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent or metallic) of the constituent atoms of the material are fulfilled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bond ...

Baker Lecture
A baker is a tradesperson who bakes and sometimes sells breads and other products made of flour by using an oven or other concentrated heat source. The place where a baker works is called a bakery. History Ancient history Since grains have been a staple food for millennia, the activity of baking is a very old one. Control of yeast, however, is relatively recent.Wayne Gisslen, ''Professional Baking'' (4th ed.: John Wiley & Sons, 2005), p. 4. By the fifth and sixth centuries BCE, the ancient Greeks used enclosed ovens heated by wood fires; communities usually baked bread in a large communal oven. Greeks baked dozens and possibly hundreds of types of bread; Athenaeus described seventy-two varieties. In ancient Rome several centuries later, the first mass production of breads occurred, and "the baking profession can be said to have started at that time." Ancient Roman bakers used honey and oil in their products, creating pastries rather than breads. In ancient Rome, bakers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-equilibrium Statistical Mechanics
In physics, statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. It does not assume or postulate any natural laws, but explains the macroscopic behavior of nature from the behavior of such ensembles. Statistical mechanics arose out of the development of classical thermodynamics, a field for which it was successful in explaining macroscopic physical properties—such as temperature, pressure, and heat capacity—in terms of microscopic parameters that fluctuate about average values and are characterized by probability distributions. This established the fields of statistical thermodynamics and statistical physics. The founding of the field of statistical mechanics is generally credited to three physicists: *Ludwig Boltzmann, who developed the fundamental interpretation of entropy in terms of a collection of microstates *James Clerk Maxwell, who developed models of probability distri ...
