Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The acceleration of a chemical reaction by a catalyst.
- ‘The partial negative charge on the oxygen atom makes it susceptible to acid catalysis.’
- ‘In general, chemical catalysis offers faster reactions times than bioremediation schemes but also tends to be more expensive.’
- ‘The regions of the monomer that move most during catalysis are shown in dark gray.’
- ‘Amides are hydrolysed to ammonium salts with catalysis by acids or alkalis.’
- ‘Interestingly, protein loops are often involved in protein activities, including ligand binding and catalysis.’
- ‘Histidines are often involved in acid base catalysis, and prone to activate nucleophiles by abstracting a proton.’
- ‘My research interests are organic chemistry mechanisms, organometallic chemistry, and heterogeneous catalysis.’
- ‘The life sciences firm specialises in the niche area of chiral catalysis, which enables the production of pharmaceuticals with reduced side effects.’
- ‘The metal catalysts are quite expensive, but since catalysis occurs at the surface, only a thin layer is required.’
- ‘Liposomes are widely used as models of biomembranes and in applications such as solar energy conversion, chemical catalysis, and drug delivery.’
- ‘Enzymes have been widely praised for their specificity and efficiency in stereospecific catalysis.’
- ‘The catalytic domain also contains an oxyanion hole that is essential for catalysis.’
- ‘The hope is to solve mysteries that Nature has long kept hidden, such as the molecular basis of catalysis and the mechanism that allows plants to split water at room temperature using sunlight.’
- ‘Heterogeneous catalysis, in which the catalyst and reactants occupy separate phases, is something of a black art when compared with homogeneous catalysis.’
- ‘One area where ionic liquids promise to make a big impact is in homogeneous catalysis, where the catalyst is typically dissolved in solution along with the reactants.’
- ‘After polymerisation using heat, light, radiation or catalysis, a range of strong thermosetting plastics can be produced.’
- ‘The most highly conserved domain is located in the C terminus of the protein and is involved in dimerization and likely in catalysis.’
- ‘In either case, the new structure represents an interesting and unique case of metal coordination in enzyme catalysis.’
- ‘The frequency shifts show an electron movement toward -phosphate, which probably contributes to catalysis by reducing the free activation energy.’
- ‘Thus, catalysis is believed to involve a one-step, metal-ion-mediated hydrolysis of the substrate by a metal-activated water molecule.’
Mid 19th century: from modern Latin, from Greek katalusis, from kataluein ‘dissolve’, from kata- ‘down’ + luein ‘loosen’.
We take a look at several popular, though confusing, punctuation marks.
