Deletion mutants of bacteriophage phiX174 [PDF]

open access: yes, 1972
Mutants of bacteriophage phiX174 have been isolated that are less dense than wild-type phiX particles in CsCl. When mutant viral (+) strand DNA and wild-type complementary (-) strand DNA are hybridized, the resulting duplex molecules have single-stranded

Temperature dependent refractive index of silicon and germanium [PDF]

open access: yes, 2006
Silicon and germanium are perhaps the two most well-understood semiconductor materials in the context of solid state device technologies and more recently micromachining and nanotechnology.

Amphiphilic Polymer Model Networks Synthesized by Different Hetero‐Complementary Coupling Reactions of Tetra‐PEG and Tetra‐PCL Stars

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 7, 14 April 2026.
Amphiphilic co‐networks (ACN) synthesized by different hetero‐complementary reactions of hydrophilic tetra‐PEG and hydrophobic tetra‐PCL stars are compared. For the ACNs, equilibrium volume swelling degrees (Qv) are determined. Information about the ACNs micro structure (connectivity distribution) is obtained from proton low‐resolution multiple‐quantum

Viscoelastic Behaviors of Hyaluronic Derivatives as a Function of pH, Salt, and Temperature

open access: yesJournal of Polymer Science, Volume 64, Issue 6, Page 1505-1517, 15 March 2026.
Viscoelastic properties of hyaluronic acid grafted with polyether side‐chains (HA‐PEPO) can be controlled in aqueous media over more than three decades of amplitude with the possibility to get liquid or gel states, regardless of temperature, as well as sol/gel transitions induced by cooling or heating by the interplay between hydrogen bonds ...

Convenient Monitoring Of Brewery Fermentation Course By Refractometry.

open access: yesKvasný průmysl, 2009
The course of wort fermentation is most often monitored by measuring density by immersion saccharometer or digital densitometer; other methods include classical analysis or automatic analyzers.

Refractive index and generalized polarizability

open access: yes, 2019
We investigate the role of retardation corrections to polarizability and to refractive index. We found that the classical electromagnetic theory of dielectrics requires corresponding modifications in terms of nonlocality of the dielectric constant.
