Nucleation of protein fibrillation by nanoparticles. [PDF]

open access: yes, 2007
Nanoparticles present enormous surface areas and are found to enhance the rate of protein fibrillation by decreasing the lag time for nucleation. Protein fibrillation is involved in many human diseases, including Alzheimer's, Creutzfeld-Jacob disease ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

High‐pressure Nucleation of Low‐Density Polymorphs

open access: yes, 2020
The crystallized above 0.3 GPa polymorphs β and γ of bis-3-nitrophenyl disulphide, are less dense than the ambient-pressure polymorph α. This high-entropy nucleation illustrates the molecular-scale mechanism of empirical Ostwald’s rule of stages.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Using HOESY NMR Spectroscopy to Characterise Pre-Nucleation Aggregates

open access: yes, 2020
Pre-nucleation aggregates are important species on the crystallisation pathway. Here we combine heteronuclear Overhauser effect spectroscopy (HOESY) and molecular dynamics calculations to study the self-association of a model system – benzoic acid.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

open access: yesAdvanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Effects of relaxants before embedding nucleus for the survival rate and pearl qualities in Pinctada fucata [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2006
Nucleation in the spherical pearl production from Akoya pearl oysters Pinctada fucata (Gould, 1850) obtained low survival rate, and the nuclei were frequently excluded.

Kinematic Equations for Front Motion and Spiral-Wave Nucleation

open access: yes, 2007
We present a new set of kinematic equations for front motion in bistable media. The equations extend earlier kinematic approaches by coupling the front curvature with the order parameter associated with a parity breaking front bifurcation. In addition to

Bubble-Nucleation-Based Method for the Selective and Sensitive Electrochemical Detection of Surfactants

open access: yes, 2019
We present the first bubble-nucleation-based electrochemical method for the selective and sensitive detection of surfactants. Our method takes advantage of the high surface activity of surfactant analyte to affect the electrochemical bubble nucleation ...

Results from the CERN pilot CLOUD experiment [PDF]

open access: yes, 2009
During a 4-week run in October–November 2006, a pilot experiment was performed at the CERN Proton Synchrotron in preparation for the Cosmics Leaving OUtdoor Droplets (CLOUD) experiment, whose aim is to study the possible influence of cosmic rays on ...
