Aligned cellulose nanocrystals and directed nanoscale deposition of colloidal spheres

, 2014
Cellulose nanocrystals are aligned in wrinkled polydimethylsiloxane templates and transferred to polyethyleneimine-coated silica surfaces in a printing process similar to microcontact printing. The highly aligned nanorods were deposited onto the surfaces

A Thermoreversible Gelation Pathway to Plant Cuticle‐Inspired Biopolymer Aerogel Monoliths Based on Network‐Spherulitic Crystal Assemblies

Advanced Materials, EarlyView.
To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...

Assessment of the Alga Cladophora glomerata as a Source for Cellulose Nanocrystals

, 2023
Nanocellulose is isolated from cellulosic fibers and exhibits many properties that macroscale cellulose lacks. Cellulose nanocrystals (CNCs) are a subcategory of nanocellulose made of stiff, rodlike, and highly crystalline nanoparticles.

Ti3C2Tx MXene/Silver Composite Foams For Lightweight, High‐Performance Electromagnetic Interference Shielding and Joule Heating

Advanced Materials Interfaces, EarlyView.
Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

Near-White Circularly Polarized Luminescence by Color Mixing Utilizing Surface-Fluorophore-Modified Cellulose Nanocrystals in Composite Films. [PDF]

Chemistry
Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (
