Liquid solution centrifugation for safe, scalable, and efficient isotope separation [PDF]

open access: yesScience Advances, 2023
A general method of separating isotopes by centrifuging dissolved chemical compounds in a liquid is introduced. This technique can be applied to almost all elements and leads to large separation factors.

Photonic crystals with rainbow colors by centrifugation-assisted assembly of colloidal lignin nanoparticles

open access: yesNature Communications, 2023
Photonic crystals are optical materials that are often fabricated by assembly of particles into periodically arranged structures. However, assembly of lignin nanoparticles has been limited due to lacking methods and incomplete understanding of the ...

Influence of scarification method on seed germination of the terrestrial orchid Anacamptis laxiflora (Lam.)

open access: yesThe EuroBiotech Journal, 2021
A critical step during in vitro sexual propagation of terrestrial orchids is the treatment of the microscopic seeds with a disinfecting solution that kills bacteria and fungi attached to the seeds.

Quantifying the Influence of Pollen Aging on the Adhesive Properties of Hypochaeris radicata Pollen

open access: yesInsects, 2022
Although pollination is one of the most crucial biological processes that ensures plant reproduction, its mechanisms are poorly understood. Especially in insect-mediated pollination, a pollen undergoes several attachment and detachment cycles when being ...

Selective loss of microvesicles is a major issue of the differential centrifugation isolation protocols

open access: yesScientific Reports, 2021
Microvesicles (MVs) are large extracellular vesicles differing in size, cargo and composition that share a common mechanism of release from the cells through the direct outward budding of the plasma membrane.

Washing solution and centrifugation affect kinematics of cryopreserved boar semen

open access: yesJournal of Animal Reproduction and Biotechnology, 2021
Cryopreservation is a widely-used efficient means of long-term sperm preservation. However, unlike other types of semen, cryopreserved boar semen has reduced fertility and the efforts continue to optimize post-thawing sperm recovery.

Influence of Centrifugation and Shaking on the Self-Assembly of Lysozyme Fibrils

open access: yesBiomolecules, 2022
Protein self-assembly into fibrils and oligomers plays a key role in the etiology of degenerative diseases. Several pathways for this self-assembly process have been described and shown to result in different types and ratios of final assemblies ...

Ultracentrifugation Techniques for the Ordering of Nanoparticles

open access: yesNanomaterials, 2021
A centrifugal field can provide an external force for the ordering of nanoparticles. Especially with the knowledge from in-situ characterization by analytical (ultra)centrifugation, nanoparticle ordering can be rationally realized in preparative (ultra ...
