Abstract: Abstract Structural artist Felix Candela pioneered the 8-sided hyperbolic paraboloidal (hypar) umbrella by introducing a parabolic discontinuity bisecting each quadrant of the classical 4-sided form. While artistically striking, such structures have never been rigorously examined… read more here.

DOI: 10.1016/j.jcrysgro.2020.125852
Abstract: Abstract Through transmission electron microscopy and related techniques, we performed structural evaluation of low-temperature grown (LTG) InGaAs crystals on (0 0 1) InP substrates. These crystals were grown at a substrate temperature of 200–250 °C. The results revealed… read more here.

Abstract: We describe the synthesis and characterization of hexabenzo[5.6.7]quinarene, which is composed of an anthraquinodimethane (AQD) central core that is end-capped with fluorenyl and dibenzosuberenyl groups. Due to strong intramolecular spin-spin interaction through the central AQD… read more here.
