In situ inward epitaxial growth of bulk macroporous single crystals

open access: yesNature Communications, 2017
Porous single crystals are desirable for optoelectronic applications, but their fabrication remains challenging. Here the authors produce centimetre-sized macroporous GaN single crystals with electron mobility comparable to that of bulk crystals via in ...

Bubble Raft Model for a Paraboloidal Crystal [PDF]

open access: yes, 2007
We investigate crystalline order on a two-dimensional paraboloid of revolution by assembling a single layer of millimeter-sized soap bubbles on the surface of a rotating liquid, thus extending the classic work of Bragg and Nye on planar soap bubble rafts.

Spin Coating Method Fabricated of In2O3 Thin Films

open access: yesAnnals of West University of Timisoara: Physics, 2019
In this work, the In2O3 thin films have been fabricated using a spin coating technique; this technique was prepared in our laboratory. The effect of the layer times (3, 5, 7 and 9 times) on optical and structural properties was investigated.

The formation of a nanohybrid shish-kebab (NHSK) structure in melt-processed composites of poly (ethylene terephthalate) (PET) and multi-walled carbon nanotubes (MWCNTs) [PDF]

open access: yes, 2017
The combination of synchrotron Small- and Wide-Angle X-ray scattering (SAXS/WAXS), and thermal analysis was used to follow the evolution of crystalline morphology and crystallization kinetics in a series of melt-processed composites of poly(ethylene ...

A possible structure for α‐crystallin [PDF]

open access: yesFEBS Letters, 1987
α‐Crystallin, the major protein of the mammalian eye lens, is found in vivo as a multimeric aggregate composed of two closely related subunits whose molar ratio is widely variable from species to species. Attempts to determine the arrangement of the subunits within the aggregate, or even to determine the size of the aggregate and the number of subunits

Structural and functional properties of indica rice starch as influenced by late-stage nitrogen fertilization

open access: yesInternational Journal of Food Properties, 2021
Late-stage nitrogen (N) fertilization is an important crop management for improving rice production and also affects the quality of rice, whereas information on the influence of late N on structural and functional properties of indica rice starch is ...

Effect of crystalline transformation on supercritical CO2 foaming and cell morphology of isotactic polybutene-1

open access: yesJournal of CO2 Utilization, 2023
As a polycrystalline polymer, isotactic polybutene-1 (iPB-1) will form different crystalline structures when it crystallizes under different conditions. In this work, we found a simple method to manipulate the cell structure of iPB-1 foams by controlling
