Crystalline Pepsin [PDF]

open access: yesScience, 1929
A method is described for the preparation of a crystalline protein from commercial pepsin preparations which has powerful peptic activity. The composition, optical activity, and proteolytic activity of this protein remain constant through seven successive crystallizations.

Short Communication: The Corrosion Behaviors of Amorphous, Nanocrystalline and Crystalline Ni-W Alloys Coating

open access: yesInternational Journal of Electrochemical Science, 2015
The corrosion behaviors of amorphous, nanocrystalline and crystalline Ni-W alloys coating were systematically investigated by ultrasonic-assisted direct current electrodeposition.

Microcone Anodic Oxide Films on Sintered Niobium Powders

open access: yesКонденсированные среды и межфазные границы, 2020
Information on the anodizing of sintered powders (SP) of niobium is limited by the study of the growth of barrier-type fi lms. The formation of a nanostructured anodic oxide fi lm (AOF) on the surface of powder particles should lead to a noticeable ...

Dynamical crystal creation with polar molecules or Rydberg atoms in optical lattices [PDF]

open access: yes, 2010
We investigate the dynamical formation of crystalline states with systems of polar molecules or Rydberg atoms loaded into a deep optical lattice. External fields in these systems can be used to couple the atoms or molecules between two internal states ...

Crystalline Nephropathies [PDF]

open access: yesArchives of Pathology & Laboratory Medicine, 2012
Context.—The kidney is a favored site for crystal deposition because of the high concentration of ions and molecules reached at the level of the renal tubules in the course of filtration. This review focuses on crystalline nephropathies in 4 broad categories: (1) dysproteinemia- associated, (2) drug-induced, (3) calcium-containing, and (4) metabolic or

Phytogenic Fabrication of Copper Oxide Nanoparticles for Antibacterial and Antioxidant Screening: Physico-Chemical Study

open access: yesCrystals, 2022
Bergenia ciliata (B. ciliate) leaf extract was used as a capping and stabilizing agent to synthesize copper oxide nanoparticles (CuO NPs). The selection of B.

Order-disorder phase change in embedded Si nano-particles

open access: yes, 2011
We investigated the relative stability of the amorphous vs crystalline nanoparticles of size ranging between 0.8 and 1.8 nm. We found that, at variance from bulk systems, at low T small nanoparticles are amorphous and they undergo to an amorphous-to ...

Crystalline color superconductors

open access: yes, 2014
Inhomogeneous superconductors and inhomogeneous superfluids appear in a variety of contexts including quark matter at extreme densities, fermionic systems of cold atoms, type-II cuprates, and organic superconductors. In the present review the focus is on

Dynamical Crystallization in the Dipole Blockade of Ultracold Atoms [PDF]

open access: yes, 2009
We describe a method for controlling many-body states in extended ensembles of Rydberg atoms, forming crystalline structures during laser excitation of a frozen atomic gas. Specifically, we predict the existence of an excitation number staircase in laser
