A tremendous amount of wheat straw (WS) has been generated by crops every year, while only a small percentage is being used in applications, and most get burned on the field, causing large exhaust gas that pollutes environment. Herein, we report extraction cellulose nanofibrils (CNF) from alkali treated WS combination 2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO)-oxidation mechanical disintegration method. The crystalline structures, thermal properties, natural charge CNF were examined....
Abstract The selective removal and immobilization of uranyl ions from aqueous solutions is essential for the sustainable development nuclear energy. Herein, a robust lanthanide‐organic framework material ( IHEP‐24 ) developed simultaneous fluorescence sensing, adsorption, photocatalytic reduction uranium, integrating three different functions in one material. confined space formed by coordination assembly viologen derivative ligands metal‐oxygen clusters can act as precise recognition sites...
Abstract The progress of stretchable and wearable photovoltaics relies heavily on intrinsically active layer films. Nevertheless, there is a paucity research clarifying the connections between their microstructure, performance, adaptation to large strain in polymer electronic current study utilizes multiple synchrotron X‐ray scattering methods collectively examine correlations morphology stretchability, as well microstructural evolution induced by stretching three sample cases highly ternary...
Abstract Self-assembly of individual building blocks into highly ordered structures, analogous to spontaneous growth crystals from atoms, is a promising approach realize the collective properties nanocrystals. Yet ability reliably produce macroscopic assemblies unavailable and key factors determining assembly quality/yield are not understood. Here we report formation superlattice films, with single crystalline domains up half millimetre in two dimensions thickness several microns...
Abstract Little is known about the induction period before nucleation and growth of colloidal semiconductor quantum dots. Here, we introduce an approach that allows us to probe intermediates present in period. We show this itself exhibits distinct stages with evolution intermediates, first without then formation covalent bonds between metal cations chalcogenide anions. The are optically invisible toluene, while covalent-bonded become visible as magic-size clusters when a primary amine added....
The stretchability and stretch-induced structural evolution of organic solar cells (OSCs) are pivotal for their collapsible, portable, wearable applications, they mainly affected by the complex morphology active layers. Herein, a highly ductile conjugated polymer P(NDI2OD-T2) is incorporated into layers high-efficiency OSCs based on nonfullerene small molecule acceptors to simultaneously investigate morphological, mechanical, photovoltaic properties under stretching ternary blend films with...
Significance As the formation of quasicrystalline ordering in both metal alloys and soft matters reinforces scale-invariance principle, however, it remains unknown that why metallic quasicrystals prefer decagonal (DQC, 10-fold) ordering, condensed maters only exhibit dodecagonal (DDQC, 12-fold) ordering. By tuning self-sorting ability a pair giant molecules, well-mixed binary blends generate metastable DQC phase corresponding unprecedent sequence (DQC → DDQC Frank–Kasper σ) during thermal...
Abstract Characterizing the bulk heterojunction (BHJ) morphology of active layer is essential for optimizing blade‐coated organic solar cells (OSCs). Here, evolution a highly efficient ternary polymer:nonfullerene blend PM6:N3:N2200 under different blade coating conditions probed in real‐time by situ synchrotron X‐ray scattering and ultraviolet‐visible (UV‐vis) spectroscopy. Besides, films at detailed ex microscopic imaging. The film exhibited optimized morphology, such as superior molecular...
Cellulose nanofibrils (CNF), as a kind of renewable, sustainable and biodegradable natural-based nanomaterial, have shown great potential application in numerous fields due to their fascinating properties. Some properties CNF-based materials are closely related cellulose polymorph crystallinity index. In this work, we present facile method for the generation CNF with tunable polymorphs via alkali treatment jute fibers under various conditions followed by (TEMPO)-mediated oxidation mechanical...
The optical system and end-station of bending-magnet beamline BL16B1, dedicated to small-angle X-ray scattering (SAXS) at the Shanghai Synchrotron Radiation Facility, is described. Constructed in 2009 upgraded 2013, this has been open users since May supports methodologies including SAXS, wide-angle (WAXS), simultaneous SAXS/WAXS, grazing-incidence (GISAXS) anomalous (ASAXS). Considering that an increasing necessity for absolute calibration SAXS intensity recognized in-depth investigations,...
Fine particulate matter (PM) air pollution has increasingly become a global problem; thus, high-performance filtration materials are in great demand. Herein, we first prepared biodegradable hierarchically structured nanocellulose-implanted filter with high capacity using freeze-drying technique. In this filter, porous structures of corrugated paper and cellulose nanofibrils (CNFs) were used as frame functional fillers, respectively. The self-assembled structure the CNF fillers could be...
In this work, we perform first-principles calculations, coupled with synchrotron small-angle x-ray scattering (SAXS) to investigate electronic origins of the chemical short-range ordering (CSRO) and reveal relationship between CSROs mechanical properties in a typical bcc (body-centered-cubic) TiZrHfNb high-entropy alloys (HEAs). It was found that existence an appropriate degree not only stabilizes HEA lattice structure, but also enhances hardness, elastic modulus, ideal strength....
Injection molding is a polymer-processing method widely used, which consumes about one-third of global plastics and produces 80% plastic parts. However, it still challenging to in situ reveal the structural evolution polymers during injection molding, long-standing obstacle understand relationship processing–structure–property.
