Most materials used for optical lighting applications need to produce a uniform illumination and require high mechanical hydrophobic properties. However, they are rarely eco-friendly. Herein, bio-based, polymer matrix-free, luminescent, film with excellent properties purposes is demonstrated. A template prepared by turning wood veneer into porous scaffold from which most of the lignin half hemicelluloses removed. The infiltration quantum dots (CdSe/ZnS) prior densification resulted in almost...
Wood is considered the most important renewable resource for a future sustainable bioeconomy. It traditionally used in building sector, where it has gained importance recent years as alternative to steel and concrete. Additionally, basis development of novel bio-based functional materials. However, wood's sustainability green often diminished by unsustainable processing modification techniques. They mostly rely on fossil-based precursors yield inseparable hybrids composites that cannot be...
Delignified wood (DW) offers a versatile platform for the manufacturing of composites, with material properties ranging from stiff to soft and flexible by preserving preferential fiber directionality natural through structure-retaining production process. This study presents facile method fabricating anisotropic mechanically tunable DW-hydrogel composites. These composites were produced infiltrating delignified spruce an aqueous gelatin solution followed chemical crosslinking. The mechanical...
The development of controlled processes for continuous hydrogen generation from solid-state storage chemicals such as ammonia borane is central to integrating renewable into a clean energy mix. However, date, most reported platforms operate in batch mode, posing challenge controllable release, catalyst reusability, and large-scale operation. To address these issues, we developed flow-through wood-based catalytic microreactors, characterized by inherent natural oriented microchannels....
Enzymes are often immobilized on solid supports to enable their recovery from reaction solutions, facilitate reuse and hence increase cost-effectiveness in application. Immobilized enzymes may even be used for flow-through applications continuous processes. However, the synthesis of traditional immobilization scaffolds techniques lack sustainability as they based fuel-based materials tedious synthesis- approaches. Here, we present natural material wood a green alternative enzyme...
In this work, we show that different enzymes, such as horseradish peroxidase (HRP), glucose oxidase, laccase, and catalase, can be directly immobilized onto plasmonic gold nanoparticles (NPs) superparamagnetic iron oxide NPs simply via unspecific physical adsorption, yielding catalytically active colloidally stable NP systems. The enzyme coating on the surface is highly robust enzymatically active. colloidal stability enzymatic performance (Vmax Km) of enzyme-coated (Au@enzyme) are strongly...
Wood is an attractive bioresource for the production of functional materials, as it provides a complex hierarchical structure with unique properties. It particularly promising membrane applications due to its aligned micropores, which enable directed flow liquids. However, wood-based membranes often rely on combination wood nonecofriendly compounds or methods. Furthermore, performance such predetermined by wood's intrinsic porosity, cannot be regulated. Here we present green sustainable...
Abstract Enzymatic biocatalysis has the potential to enable greener and more efficient synthesis routes for chemical industry. However, enzymes are hard remove recover from reaction solution due homogeneous nature of biocatalysis. Hence, often limited single‐use applications. This work shows immobilization based on nanoparticle‐mediated robust physisorption natural cellulose fibers. The resulting hybrid material is able perform heterogeneous catalytic activity multifold reusability...
Compliant materials are indispensable for many emerging soft robotics applications. Hence, concerns regarding sustainability and end-of-life options these growing, given that they predominantly petroleum-based non-recyclable. Despite efforts to explore alternative bio-derived like gelatin, frequently fall short in delivering the mechanical performance required actuating systems. To address this issue, we reinforced a compliant transparent gelatin-glycerol matrix with structure-retained...
In this study, we present a novel and facile method for the synthesis of multiresponsive plasmonic nanoparticles with an interesting interfacial behavior. We used thiol-initiated photopolymerization technique to graft poly(N-isopropylacrylamide) onto surface protein-coated gold nanoparticles. The combination protein bovine serum albumin thermoresponsive polymer leads smart hybrid nanoparticles, which show stimuli-responsive behavior their aggregation precisely controllable phase transfer...
