Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves

open access: yesAdvanced Engineering Materials, EarlyView.
Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

Entropy and the Tolman Parameter in Nucleation Theory

open access: yesEntropy, 2019
Thermodynamic aspects of the theory of nucleation are commonly considered employing Gibbs’ theory of interfacial phenomena and its generalizations. Utilizing Gibbs’ theory, the bulk parameters of the critical clusters governing nucleation can

Trans‐Conductive Melt Pool Scaling and its Implications for Parameter Transfer in Laser Powder Bed Fusion for Metals with High Thermal Diffusivity

open access: yesAdvanced Engineering Materials, EarlyView.
Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Condensation: Passenger Not Driver in Atmospheric Thermodynamics

open access: yesEntropy, 2016
The second law of thermodynamics states that processes yielding work or at least capable of yielding work are thermodynamically spontaneous, and that those costing work are thermodynamically nonspontaneous.

Synthesis and antimicrobial activity of a new series of 1,4-dihydropyridine derivatives [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
A series of 1,4-dihydropyridine derivatives (1a–g) were prepared from Hantzsch syntheses. The compounds 1a–g were reacted with thiosemicarbazide to give the new series of compounds 2a–g. IR, 1H-NMR, 13C-NMR, mass spectral and elemental analysis confirmed

Dynamics of Instantaneous Condensation in the ZRP Conditioned on an Atypical Current

open access: yesEntropy, 2013
Using a generalized Doob’s h-transform we consider the zero-range process (ZRP) conditioned to carry an atypical current, with focus on the regime where the Gallavotti-Cohen symmetry loses its validity.

Laser cooling all the way down to molecular condensate [PDF]

open access: yes, 2005
Numerical simulations show that laser cooling of fermions on the repulsive side of the Feshbach resonance can sympathetically cool molecules well below their condensation temperature.
