Physics of $\pi$-Meson Condensation and High Temperature Cuprate Superconductors

open access: yes, 2009
The idea of condensation of the Goldstone $\pi$-meson field in nuclear matter had been put forward a long time ago. However, it was established that the normal nuclear density is too low, it is not sufficient to condensate $\pi$-mesons. This is why the $\

One-loop Correction and the Dilaton Runaway Problem [PDF]

open access: yes, 1995
We examine the one-loop vacuum structure of an effective theory of gaugino condensation coupled to the dilaton for string models in which the gauge coupling constant does not receive string threshold corrections.

Cytoplasmic condensation induced by membrane damage is associated with antibiotic lethality

open access: yesNature Communications, 2021
Bactericidal antibiotics kill bacteria by perturbing various cellular targets and processes. Disruption of the primary antibiotic-binding partner induces a cascade of molecular events, leading to overproduction of reactive metabolic by-products.

Selective and eco-friendly procedures for the synthesis of benzimidazole derivatives. The role of the Er(OTf)3 catalyst in the reaction selectivity

open access: yesBeilstein Journal of Organic Chemistry, 2016
An improved and greener protocol for the synthesis of benzimidazole derivatives, starting from o-phenylenediamine, with different aldehydes is reported. Double-condensation products were selectively obtained when Er(OTf)3 was used as the catalyst in the ...

Tachyon condensation and Boundary States in Bosonic String [PDF]

open access: yes, 2000
We discuss tachyon configuration for the unoriented bosonic string theory which produces a bosonic string theory with SO(32) gauge symmetry in ten dimensions. It is closely related to the tachyon condensation scenario proposed by A. Sen. We also give the

Condensate Halos in Condensation Frosting

open access: yesAdvanced Science
AbstractThe freezing of water drops on cold solid surfaces is ubiquitous in nature, and generally causes serious technological, engineering, and economic issues in industrial applications. Despite longstanding research efforts, existing knowledge on dropwise freezing is still limited, as this phase‐change phenomenon is always accompanied by complex ...

Synthesis of [(4-Chloro-5H-1,2,3-dithiazol-5-ylidene)amino]azines

open access: yesMolecules, 2011
The reactions of 2-, 3- and 4-aminopyridines with 4,5-dichloro-1,2,3-dithiazol-ium chloride (Appel salt) 4 to give N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)pyridin-X-amines 1a (X = 2), 1g (X = 3) and 1k (X = 4) were optimized with respect to base ...
