Deep Crustal Heating in a Multicomponent Accreted Neutron Star Crust

open access: yes, 2012
A quasi-statistical equilibrium model is constructed to simulate the multicomponent composition of the crust of an accreting neutron star. The ashes of rp-process nucleosynthesis are driven by accretion through a series of electron captures, neutron ...

Dynamic p-enrichment schemes for multicomponent reactive flows

open access: yes, 2011
We present a family of p-enrichment schemes. These schemes may be separated into two basic classes: the first, called \emph{fixed tolerance schemes}, rely on setting global scalar tolerances on the local regularity of the solution, and the second, called

Interfacial instability-driven amorphization/nanocrystallization in a bulk Ni45Cu5Ti33Zr16Si1 alloy during solidification [PDF]

open access: yes, 2005
We report on experimental evidence for local amorphization/nanocrystallization at the interfaces between the B2-ordered Ni(Ti,Zr) phase and the NiTiZr phase with P63/mmc during solidification of a multicomponent Ni45Cu5Ti33Zr16Si1 alloy. So far there are

Designed Liquid Crystalline Nanoassemblies From Clinically Validated Polyunsaturated Lipids for Combined Antioxidant, Anti‐Apoptotic, and Neurotrophic Treatments

open access: yesAdvanced Healthcare Materials, EarlyView.
Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs

Advances of Ugi reaction in natural product synthesis

open access: yesGreen Synthesis and Catalysis
The Ugi multicomponent reaction represents a highly efficient synthetic transformation, wherein all four reactants (isocyanides, amine, aldehyde or ketone and a nucleophile) are combined in one pot under mild conditions. This reaction exhibits remarkable

The Bucherer–Bergs Multicomponent Synthesis of Hydantoins—Excellence in Simplicity

open access: yesMolecules, 2021
Hydantoins and their hybrids with other molecules represent a very important group of heterocycles because they exhibit diverse biological and pharmacological activities in medicinal and agrochemical applications. They also serve as key precursors in the

Modelling of simultaneous mass and heat transfer with chemical reaction using the Maxwell-Stefan theory I. Model development and isothermal study [PDF]

open access: yes, 1995
A general applicable model has been developed which can predict mass and heat transfer fluxes through a vapour/gas-liquid interface in case a reversible chemical reaction with associated heat effect takes place in the liquid phase.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
