Global nitrogen (N) deposition patterns have profoundly affected the production and morphological structure of fine roots, which in turn changed distribution carbon forests. However, traditional experiments N addition forests ignored ecological processes canopy, such as retention, effects these on root functional traits remain unclear. In this study, we quantified canopy (CAN) understory (UAN) biomass morphology roots a temperate deciduous forest. Based three-way ANOVA, found that treatment...

Abstract Most tough hydrogels are reinforced by introducing energy dissipation mechanisms, but simultaneously realizing a high toughness and low hysteresis is challenging because the structure cannot recover rapidly. In this work, mechanical performance highly entangled double network without fabricated, in which physical entanglements act as primary effective crosslinking first network. This sliding entanglement allows hydrogel to form uniform oriented during stretching, resulting tensile...

Understanding nanoparticle growth mechanisms is crucial for the synthesis of nanocrystals with desired biological and chemical properties. Growth by oriented attachment (OA) frequently reported as a method supplementary to classical Ostwald ripening (OR) process. In this work, ZnO nanoparticles (NPs) were prepared wet method. Size/shape evolution NPs in ethanol solution was systematically studied using transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray diffraction...

Development of functional materials capable exhibiting chirality tunable circularly polarized luminescence (CPL) is currently in high demand for potential technological applications. Herein we demonstrate the formation both left- and right-handed fluorescent helical superstructures from each enantiomer a chiral tetraphenylethylene derivative through judicious choice solution processing conditions. Interestingly, aggregation induced emission active enantiomers exhibit handedness inversion...

ZnO nanoparticles are widely used in biological, chemical, and medical fields, but their toxicity impedes wide application. In this study, pristine NPs (~ 7 nm; ~ 18 49 nm) lipid-coated 13 22 52 with different morphologies were prepared by chemical method characterized TEM, XRD, HRTEM, FTIR, DLS. Our results showed that the groups improved colloidal stability, prevented aggregation dissolution of nanocrystal particles solution, inhibited into Zn2+ cations, reduced cytotoxicity more...

Introduction Increasing atmospheric N deposition and changes in precipitation patterns could profoundly impact forest community structure ecosystem functions. However, most water (W) addition experiments have focused on direct application to leaf litter or soil, neglecting canopy processes such as evaporation absorption. Methods In this study, we aimed assess the effects of increased fine root biomass morphology plants a temperate deciduous forest. To achieve this, applied W above quantified...

A pervasive threat regarding human health, ecological balance, progress, and sustainability marks the current era. Many nations are grappling with consequences of overabundance carbon emissions from a wide range destructive activities, which is primary driver air pollution, global warming, warming. Thus, while some countries squandering their riches, others making great strides to keep environment clean green so that future generations may thrive. National governments policymakers now...

It has been widely reported that cellulose nanocrystals (CNCs) demonstrate a special structural color, which stems from chiral nematic domains. Herein, the humidity and heat dual response nanocomposite films with multilayered helical structure were prepared by self-assembling of CNCs hydrazone groups modified poly(N-isopropylacrylamide) (PNIPAM) copolymers. Furthermore, glutaraldehyde was involved to act as chemical linker improve cyclic stability forming acylhydrazone bonds. The color could...

Abstract Facile functionalization of multilayer fullerenes (carbon nano‐onions, CNOs) was carried out by [2+1] cycloaddition nitrenes. The products were further derivatized using the “grafting from” strategy in situ ring‐opening polymerization (ROP) and atom transfer radical (ATRP). Using one‐step nitrene chemistry with high‐energy reagents, such as azidoethanol azidoethyl 2‐bromo‐2‐methyl propanoate, N ‐methyl‐2‐pyrrolidone at 160°C for 16 h, hydroxyl bromide functionalities introduced onto...
