The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]

open access: yesJournal of the European Ceramic Society, Volume 32, Issue 1, 2012, Pages 235-244, 2013
The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

Comparative Study of Immobilized Biolipasa‐R for Second Generation Biodiesel Production from an Acid Oil

open access: yesChemBioChem, Volume 25, Issue 21, November 4, 2024.
Biolipasa‐R immobilized via adsorption on diatomaceous earth and commercial carriers efficiently catalyzes the production of fatty acid methyl esters from acid oils, for the preparation of second‐generation biodiesel. It's performance in this process is superior to benchmark enzyme Novozym® 435. Abstract The primary objective of this work is to develop

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]

open access: yes, 2014
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.

POLYMETHACRYLIC ACID: INDUCTION OF LYMPHOCYTOSIS AND TISSUE DISTRIBUTION

open access: yesCell Proliferation, 1975
AbstractPolymethacrylic acid (PMAA) induces up to a three‐fold increase in the lymphocyte population of peripheral blood in rats, goats and calves after intravenous administration. Other routes of administration are less effective. A maximum lymphocytosis is achieved after 3 hr with all doses in excess of 30 mg PMAA/kg body weight; over the next few ...

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]

open access: yesIcarus, 2019, 319, 685-700, 2018
The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...
