ON THE PRECISION OF THE NUCLEATOR

Image Analysis & Stereology, 2017
The nucleator is a design unbiased method of local stereology for estimating the volume of a bounded object. The only information required lies in the intersection of the object with an isotropic random ray emanating from a fixed point (called the pivotal point) associated with the object.

Synthesis of Zinc-Sulfate Nano Particles and Detection of Their Induction Time, Nucleation Rate and Interfacial Tension [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2019
The production of zinc sulfate is important both medically and agriculturally. If zinc sulfate is produced without agglomeration at the nanoscale, its absorption in the body is more and faster.

Investigation on the graphite nucleation and growth mechanism of the compacted graphite iron

Journal of Materials Research and Technology, 2020
This paper investigates the three-dimensional spatial characteristics of graphite in compacted graphite iron (CGI), at different crystallization stages, by interrupting the solidification process through experimental technique and taking three ...

Earthquake nucleation in weak subducted carbonates [PDF]

, 2016
Ocean-floor carbonate- and clay-rich sediments form major inputs to subduction zones, especially at low-latitude convergent plate margins. Therefore, knowledge of their frictional behaviour is fundamental for understanding plate-boundary earthquakes ...

An In-Situ LSCM Study on Bainite Formation in a Fe-0.2C-1.5Mn-2.0Cr Alloy

Metals, 2018
Direct microscopic observation of the isothermal bainite evolution in terms of nucleation events, the location of the nuclei, as well as their growth is very valuable for the refinement of models predicting the kinetics of bainite transformation. To this

Evolution of a Polydisperse Ensemble of Spherical Particles in a Metastable Medium with Allowance for Heat and Mass Exchange with the Environment

Crystals, 2022
Motivated by a wide range of applications in various fields of physics and materials science, we consider a generalized approach to the evolution of a polydisperse ensemble of spherical particles in metastable media.

Hierarchies in nucleation transitions [PDF]

Computer Physics Communications, 2011
We discuss the hierarchy of subphase transitions in first-order-like nucleation processes for an exemplified aggregation transition of heteropolymers. We perform an analysis of the microcanonical entropy, i.e., the density of states is considered as the central statistical system quantity since it connects system-specific entropic and energetic ...

Adipic acid primary nucleation kinetics from probability distributions in droplet-based systems under stagnant and flow conditions [PDF]

, 2015
In this work, we present a microfluidic approach that allows performing nucleation studies under different fluid dynamic conditions. We determine primary nucleation rates and nucleation kinetic parameters for adipic acid solutions by using liquid/liquid ...
