Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Isothermal crystallization kinetics of poly(ethylene terephthalate) and poly(methyl methacrylate) blends

open access: yeseXPRESS Polymer Letters, 2007
Different kinetic models like the Avrami, Tobin and Urbanovici-Segal models have been applied for determining the isothermal crystallization kinetics of virgin poly(ethylene terephthalate) (PET) and PET/poly(methyl methacrylate) (PMMA) blends.

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

Nanofluidics Approach to Separate between Static and Kinetic Nanoconfinement Effects on the Crystallization of Polymers

open access: yes, 2015
International audienceHere we report a nanofluidics approach that allows one to discriminate, for the first time, between static and kinetic effects on the crystallization of polymers in 2-dimensional nanoconfinement.

Evaluation of industrial beet sugar crystallization in order to increase the exhaustion of molasses [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2013
The aim of the sugar beet processing is to achieve the highest sugar quality and yield with the lowest energy consumption together with the most effective use of equipment and time. After product crystallization is the most important stage.

Dynamic Supercooled Crystal-Gels for Ultrafast, Reversible Mechanical Adaptative Materials. [PDF]

open access: yesAdv Sci (Weinh)
A dynamic supercooled crystal–gel mimics starfish tissue by storing non‐equilibrium energy in a metastable liquid. A gentle touch triggers templated crystallization, producing a 2596‐fold stiffness increase with negligible volume change. The lattice disintegrates reversibly under humidity or warmth.

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Isothermal batch crystallization of alpha-lactose: A kinetic model combining mutarotation, nucleation and growth steps

open access: yes, 2009
 A kinetic model combining first-order differential equations of the three consecutive steps of lactose crystallization, i.e., mutarotation, nucleation and crystal growth rate, was developed.

Culinary Chemistry as a Platform for Interfacial Materials Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.
