Oriented nucleation in formamidinium perovskite for photovoltaics

Nature, 2023
The black phase of formamidinium lead iodide perovskite is used to make highly efficient solar cells, and a technique to improve its purity and stability by controlling crystal nucleation could make them even better. The black phase of formamidinium lead

Tuning Transport Phenomena in Agarose Gels for the Control of Protein Nucleation Density and Crystal Form

Crystals, 2021
Agarose gels provide the ideal environment for studying the nucleation step of complex biomacromolecules under diffusion-controlled conditions. In the present paper, we characterized the influence of agarose on the nucleation of three model proteins, i.e.

γ-Tubulin Complexes and Fibrillar Arrays: Two Conserved High Molecular Forms with Many Cellular Functions

Cells, 2021
Higher plants represent a large group of eukaryotes where centrosomes are absent. The functions of γ-tubulin small complexes (γ-TuSCs) and γ-tubulin ring complexes (γ-TuRCs) in metazoans and fungi in microtubule nucleation are well established and the ...

Co-Crystallization Kinetics of 2:1 Benzoic Acid–Sodium Benzoate Co-Crystal: The Effect of Templating Molecules in a Solution

Crystals, 2021
The addition of dissolved templating molecules in crystallization will create “supramolecular assemblies” within the solution, serving as “anchor points” for the solute molecules to nucleate and grow.

Prenucleation at the Liquid/Substrate Interface: An Overview

Metals, 2022
Prenucleation refers to the phenomenon of substrate-induced atomic ordering in the liquid adjacent to the liquid/substrate interface at temperatures above the nucleation temperature.

Biochemical reconstitution of branching microtubule nucleation

eLife, 2020
Microtubules are nucleated from specific locations at precise times in the cell cycle. However, the factors that constitute these microtubule nucleation pathways and their mode of action still need to be identified. Using purified Xenopus laevis proteins

Phase-field modeling of grain evolutions in additive manufacturing from nucleation, growth, to coarsening

npj Computational Materials, 2021
A three-dimensional phase-field model is developed to simulate grain evolutions during powder-bed-fusion (PBF) additive manufacturing, while the physically-informed temperature profile is implemented from a thermal-fluid flow model. The phase-field model

Microtubule Anchoring: Attaching Dynamic Polymers to Cellular Structures

Frontiers in Cell and Developmental Biology, 2022
Microtubules are dynamic, filamentous polymers composed of α- and β-tubulin. Arrays of microtubules that have a specific polarity and distribution mediate essential processes such as intracellular transport and mitotic chromosome segregation. Microtubule

Reversible disorder-order transitions in atomic crystal nucleation

Science, 2021
Watching early stage nucleation In classic nucleation theory, a metastable disordered dense liquid or amorphous solid cluster spontaneously and irreversibly transforms into a crystalline nucleus. Jeon et al.
