Hydrodynamically-driven colloidal assembly in the thin-film entrainment regime [PDF]
Phys. Rev. Lett. 110, 18830 (2013), 2012 We study numerically the hydrodynamics of dip coating from a suspension and report a mechanism for colloidal assembly and pattern formation on smooth and uniform substrates. Below a critical withdrawal speed of the substrate, capillary forces required to deform the meniscus prevent colloidal particles from entering the coating film.

Performance analysis of a direct-absorption parabolic trough solar collector [PDF]
Renew. Energy 143, 24, 2019, 2018 A parabolic trough solar collector is a dominant technology for high-temperature industrial applications, but efficient use of a conventional surface-based parabolic trough solar collector (SBPTSC) is limited by its high radiation loss due to the high surface temperature.

Quantum magnetomechanics: towards the ultra-strong coupling regime [PDF]
Phys. Rev. B 97, 024109 (2018), 2017 In this paper we investigate a hybrid quantum system comprising a mechanical oscillator coupled via magnetic induced electromotive force to an $LC$ resonator. We derive the Lagrangian and Hamiltonian for this system and find that the interaction can be described by a charge-momentum coupling with a strength that has a strong geometric dependence.

Evolution of a physiological pH 6.8 bicarbonate buffer system: application to the dissolution testing of enteric coated products. [PDF]
, 2011 The use of compendial pH 6.8 phosphate buffer to assess dissolution of enteric coated products gives rise to poor in vitro-in vivo correlations because of the inadequacy of the buffer to resemble small intestinal fluids.

Pharmaceutics, 2020 The in vivo dissolution of enteric-coated (EC) products is often overestimated by compendial in vitro dissolution experiments. It is of great interest to mimic the in vivo conditions as closely as possible in vitro in order to predict the in vivo ...

A brief review on recent advancement of tablet coating technology
Journal of Applied Pharmaceutical Research, 2022 A tablet can be defined as a solid unit dosage form. There are several reasons for coating of solid dosage form, the most important reason is to control the release profile & also to control the bioavailability parameters of the APIs (Active ...
