Making Asymmetric Dark Matter Gold: Early Universe Synthesis of Nuggets [PDF]

open access: yesPhys. Rev. D 97, 036003 (2018), 2017
We compute the mass function of bound states of Asymmetric Dark Matter--nuggets--synthesized in the early Universe. We apply our results for the nugget density and binding energy computed from a nuclear model to obtain analytic estimates of the typical nugget size exiting synthesis.

Surface-Wave Dispersion Retrieval Method and Synthesis Technique for Bianisotropic Metasurfaces [PDF]

open access: yesPhys. Rev. B 99, 155140 (2019), 2018
We propose a surface-wave dispersion retrieval method and synthesis technique that applies to bianisotropic metasurfaces that are embedded in symmetric or asymmetric environments. Specifically, we use general zero-thickness sheet transition conditions to relate the propagation constants of surface-wave modes to the bianisotropic susceptibility ...

Giant asymmetric self-phase modulation in superconductor thin films [PDF]

open access: yesarXiv, 2017
Self-phase modulation (SPM) of light pulses is found to occur strongly, at low incident intensities, in the coupling of light with superconductors. We develop a theory from a synthesis of the time-dependent Ginzburg-Landau (TDGL) equation and basic electrodynamics which shows the strongly non-linear phase accumulated in the interaction.

Large-area synthesis of continuous two-dimensional MoTexSe2-x alloy films by chemical vapor deposition [PDF]

open access: yes, 2019
Great achievements have been made in alloying of two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), which can allow tunable band gaps for practical applications in optoelectronic devices. However, telluride-based TMDs alloys were less studied due to the difficulties of sample synthesis.

Recent Advances in π-Stacking Interaction-Controlled Asymmetric Synthesis [PDF]

open access: yesMolecules
The π-stacking interaction is one of the most important intramolecular and intermolecular noncovalent interactions in organic chemistry. It plays an important role in stabilizing some structures and transition states in certain reactions via both ...

Synthesis of novel phthalimido oxime pseudoesters and evaluation of their cytotoxicity [PDF]

open access: yesJournal of the Serbian Chemical Society, 2020
A series of novel optically pure oxime pseudoesters derivatives were synthesized by the reaction of substitute keto oximes with various N-substituted α-amino acids chlorides in the presence of triethylamine and dichloromethane at 0°C, and their ...

Recent Advances in DMSO-Based Direct Synthesis of Heterocycles

open access: yesMolecules, 2022
Besides serving as a low-toxicity, inexpensive and easily accessible solvent, dimethyl sulfoxide (DMSO) has also been extensively used as a versatile reagent for the synthesis of functionalized molecules.
