Single-crystal NMR spectroscopy [PDF]

Progress in Nuclear Magnetic Resonance Spectroscopy, 2021
Single-crystal (SC) NMR spectroscopy is a solid-state NMR method that has been used since the early days of NMR to study the magnitude and orientation of tensorial nuclear spin interactions in solids. This review first presents the field of SC NMR instrumentation, then provides a survey of software for analysis of SC NMR data, and finally it highlights

Single-Crystal Polycationic Polymers Obtained by Single-Crystal-to-Single-Crystal Photopolymerization

Journal of the American Chemical Society, 2020
The efficient preparation of single-crystalline ionic polymers and fundamental understanding of their structure-property relationships at the molecular level remains a challenge in chemistry and materials science. Here, we describe the single-crystal structure of a highly ordered polycationic polymer (polyelectrolyte) and its proton conductivity.

Photodriven single-crystal-to-single-crystal transformation [PDF]

Coordination Chemistry Reviews, 2017
Abstract Molecular architectures containing photosensitive units respond to light, giving dramatic variations of their structure. In particular, the crystalline packing phases offer the possibility of significant advances in crystal design and the understanding of solid-state photoreactivity.

Redetermination of the crystal structure of yttrium chromium tetraboride, YCrB4, from single-crystal X-ray diffraction data

Acta Crystallographica Section E: Crystallographic Communications, 2023
The structural parameters of yttrium chromium tetraboride YCrB4 were refined based on single-crystal X-ray diffraction data. YCrB4 is orthorhombic, having a space group of type Pbam (No. 55) and with lattice parameters of a = 5.9425 (2), b = 11.4831 (4),

Room temperature continuous wave operation of single-mode, edge-emitting photonic crystal Bragg lasers [PDF]

, 2008
We report the first room temperature CW operation of two dimensional single-mode edge-emitting photonic crystal Bragg lasers. Single-mode lasing with single-lobed, diffraction limited far-fields is obtained for 100μm wide and 550μm long on-chip devices ...

Single Crystal to Single Crystal Transformations [PDF]

Australian Journal of Chemistry, 2006
The past decade has witnessed escalating interest in solidstate phase transitions that involve significant changes in structure without appreciable loss of crystal mosaicity— single crystal to single crystal (SC-SC) transformation.[1–5] Several factors have contributed to these studies: increased general access to X-ray diffraction facilities ...

Single-crystal two-dimensional material epitaxy on tailored non-single-crystal substrates

Nature Communications, 2022
The heteroepitaxial growth of crystalline 2D materials is usually based on single-crystal substrates. Here, the authors demonstrate that single-crystal graphene and hexagonal boron nitride films can be successfully grown on wafer-scale copper foils with ...
