Control of crystal polymorph in microfluidics using molluscan 28 kDa Ca2+-binding protein [PDF]

open access: yes, 2010
Biominerals produced by biological systems in physiologically relevant environments possess extraordinary properties that are often difficult to replicate under laboratory conditions.

Making ARPES Measurements on Corrugated Monolayer Crystals: Suspended Exfoliated Single-Crystal Graphene

open access: yes, 2011
Free-standing exfoliated monolayer graphene is an ultra-thin flexible membrane, which exhibits out of plane deformation or corrugation. In this paper, a technique is described to measure the band structure of such free-standing graphene by angle-resolved

Surface-Enhanced Plasmon Splitting in a Liquid-Crystal-Coated Gold Nanoparticle [PDF]

open access: yes, 2005
We show that, when a gold nanoparticle is coated by a thin layer of nematic liquid crystal, the deformation produced by the nanoparticle surface can enhance the splitting of the nanoparticle surface plasmon.

An Optical Microscope Study of the Morphology of Xenon Hydrate Crystals: Exploring New Approaches to Cryopreservation

open access: yesCrystals, 2019
One of the possible approaches to a new method of cryopreservation seems to be the controlled formation of a multitude of small crystals in an object, which, due to their size, will not damage cellular structures.

Effects of Different Shade Treatments on the Epidermal Wax Deposition of Hosta Genotypes with Different Glaucousness of Leaf Surface

open access: yesHorticulturae
Epidermal wax is strategically situated at the interface between plants and air; therefore, it plays a key role in plants’ interactions with their surroundings. It is also unstable and susceptible to light intensity.

Structural aspects of displacive transformations: what can optical microscopy contribute? Dehydration of Sm2(C2O4)3·10H2O as a case study

open access: yesIUCrJ, 2017
For martensitic transformations the macroscopic crystal strain is directly related to the corresponding structural rearrangement at the microscopic level.

The morphology of bone mineral crystals

open access: yesCalcified Tissue Research, 1978
Electron microscopical observations of the size and shape of bone mineral crystallites have not been in complete agreement with X-ray diffraction findings. The two prevalent viewpoints consider bone mineral crystals to be either rod, or plate like in habit.

The physics of snow crystals [PDF]

open access: yes, 2005
We examine the physical mechanisms governing the formation of snow crystals, treating this problem as a case study of the dynamics of crystal growth from the vapour phase.

Luminescent analysis of the quality of CdS nanocrystals depending on technological parameters

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2019
This work is devoted to luminescent investigations of CdS nanowhiskers grown in different technological approaches with variable parameters, what allows to control sizes and morphology of grown nanocrystals. Luminescence was used for the express analysis
