Capillary phenomena governing the mass-transport (capillary filling, condensation/evaporation) has been experimentally investigated in around 20 different silica thin films exhibiting various porosities with pores dimension ranging from 2 to 200 nm. Films have been prepared by sol-gel chemistry combined with soft-templating approaches and controlled dip coating process. Environmental ellipsomet...

Despite the excellent properties of mineral trioxide aggregate (MTA), the condensation technique may have some influence in its sealing ability. The purpose of this study was to compare the sealing ability of sonic and ultrasonic setting of MTA. Thirty-four extracted human teeth had their canals prepared and filled with Sealapex sealer and gutta-percha using the active lateral condensation tech...

We determine simple analytical conditions for combined radiative and thermal equilibrium between the X-ray emitting plasma and cold reprocessor in active galactic nuclei (AGN) and galactic black holes (GBH). These conditions determine the pressure at the transition zone, which is not arbitrary in the static situation. The conditions for static solution are derived analytically for different for...

It was argued in \cite{DallAgata:2022abm} that the Volkov-Akulov (VA) model as well similar models supergravity and related KKLT string theory, suffer from tachyonic instabilities due to goldstino condensation. The authors of constructed a specific with two unconstrained interacting chiral superfields linearly realized supersymmetry which has an unstable vacuum. They claimed this becomes equiva...

the silver spr chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (aptes) in naoh aqueous solution at different times. silver sputtered slides coated with aptes were immersed in naoh solution, enabling us to produce silver surfaces homogeneously covered with aptes. the surface properties of grafted aptes on sputtered silver surface as a occasion of time were studi...

vilsmeier several diamide derivatives containing 2-chloroquinoline scaffolds were synthesized via ugi reaction of 2-chloroquinoline-3-carboxaldehydes, amines, carboxylic acids and isocyanides. the diversity of these quinolinyl ugi-adducts was increased by using 2-chloroquinoline-3-carboxylic acids as a source of acid. among them, compounds 2d, 2n, 2p, 4a, 4c and 4e displayed moderate to good an...
