Borosilicate nanoparticles prepared by exothermic phase separation
Nature Nanotechnology, 2008Nanoparticles play an important role in chemical and biological sciences due to their ability to bind and concentrate many molecules on their surface. Polymers and silica are widely used to make nanoparticles, but efforts to make nanoparticles from borosilicate glass--which exhibits high tolerance to chemicals and solvents, combined with excellent ...

Preparative-scale isoelectric trapping enantiomer separations
Journal of Chromatography A, 2003The new Gradiflow BF200 IET unit, developed for isoelectric trapping protein separations has been modified and used to carry out preparative-scale enantiomer separations. Hydroxypropyl beta-cyclodextrin was used as the chiral resolving agent to induce an isoelectric point difference between the enantiomers.

Phase separation in frozen erythrocyte membrane preparations
Journal of Microscopy, 1985SUMMARYThe reversible formation of a lipid‐like phase in frozen preparations of erythrocyte membranes has been studied by X‐ray diffraction and by electron microscopy of freeze‐fracture replicas. The observations provide strong evidence for lateral migration or displacement at specific temperatures of intra‐membrane particles.

Hydroxamates of tissue-activated acyls: Preparation and separation
Biochimica et Biophysica Acta, 1959Abstract To determine the amount of reactive acyl present in tissue with the aid of hydroxylamine, it is necessary to heat inactive (10 min, 70°) the enzymes responsible for the enzymic formation of hydroxamates. Such heat treatment is shown to leave intact the thiol acyl forms of the monobasic acids studied but to destroy the succinyl derivative ...

Role of simulation in preparation for the care of conjoined twins-prenatal preparation to separation
Seminars in Perinatology, 2018The rarity and complexity of conjoined twins creates a challenge for prenatal planning, delivery resuscitation, and postnatal management. The modality of simulation offers a safe practice environment for a multidisciplinary group consisting of neonatal providers, nurses, respiratory therapists, and surgeons in which to identify and address clinical ...

Enantiomer separation of hydrocarbons in preparation for ROSETTA's “chirality‐experiment”
Chirality, 2001AbstractUntil now the favored method for separating racemic pairs of underivatized alcohols, diols, and phenylsubstituted amines has been gas chromatography on cyclodextrin phases. However, certain enantiomers of saturated chiral hydrocarbons could not be resolved in this way because they lack the functional groups necessary to undergo “intensive ...
