“…These substances can effectively impart a high surface density charge or zeta potential and specific interlayer distance (d 0 or d vdW ), contributing to the consistent electrostatic stability of colloids (stably charged) [128]. For example, colloidal suspensions with a zeta potential value greater than 30 mV or less than −30 mV, depending on the nature of the surface charge, are generally considered solely stable [135]. Correspondingly, the efficacy of the organic ILs in creating a polar environment has been found to be favorable for the dispersion and stabilization of quasi-2D/1D colloids compared to other dispersants and stabilizers [136,137].…”

In the pursuit of advanced functional materials, the role of low-dimensional van der Waals (vdW) heterointerfaces has recently ignited noteworthy scientific interest, particularly in assemblies that incorporate quasi-2D graphene and quasi-1D nanocellulose derivatives. The growing interest predominantly stems from the potential to fabricate distinct genres of quasi-2D/1D nanoarchitecture governed by vdW forces. Despite the possibilities, the inherent properties of these nanoscale entities are limited by in-plane covalent bonding and the existence of dangling π-bonds, constraints that inhibit emergent behavior at heterointerfaces. An innovative response to these limitations proposes a mechanism that binds multilayered quasi-2D nanosheets with quasi-1D nanochains, capitalizing on out-of-plane non-covalent interactions. The approach facilitates the generation of dangling bond-free iso-surfaces and promotes the functionalization of multilayered materials with exceptional properties. However, a gap still persists in understanding transition and alignment mechanisms in disordered multilayered structures, despite the extensive exploration of monolayer and asymmetric bilayer arrangements. In this perspective, we comprehensively review the sophisticated aspects of multidimensional vdW heterointerfaces composed of quasi-2D/1D graphene and nanocellulose derivatives. Further, we discuss the profound impacts of anisotropy nature and geometric configurations, including in-plane and out-of-plane dynamics on multiscale vdW heterointerfaces. Ultimately, we shed light on the emerging prospects and challenges linked to constructing advanced functional materials in the burgeoning domain of quasi-3D nanoarchitecture.

The development of energy-saving materials in buildings based on biomass materials is a general consensus building construction of low-carbon cities. Herein, we reported an effective ultraviolet (UV)-filtered film, composed of carbon quantum dots (CDs) and cellulose nanocrystals (CNC). The results showed that CNC had nanoscale dimensions with a diameter of 20−50 nm and length of 250−450 nm, a high crystallinity index of 84.7%, and enrichment of hydrogen bonds on the surface. The photoluminescence spectra showed that ligninbased carbon quantum dots (CDs) exhibited a long-wavelength red emission (623 nm) and an uncommon narrow emission bandwidth (fwhm <30 nm). In addition, the prepared UV-filtered film had strong mechanical tensile properties, good UV light absorbing capability, and water resistance. The optical test showed that the film also had highly optical transparency (94%) and haze (70%). The excellent light management and conversion function of this film provides a new user experience for soft, uniform, healthy, and comfortable indoor sunlight lighting.
