ABSTRACT Lignin, comprising 20%–35% of lignocellulosic biomass, is the second most abundant biopolymer after cellulose. As bioethanol industry expands, accumulation lignin by‐products necessitates innovative valorization strategies. This study explores synthesis and characterization lignin‐derived composites. Specifically, reaction 20 wt. % guaiacol or syringol with 80 elemental sulfur gives composites GS SS , respectively. The chemical structures were elucidated using GC–MS, 1 H NMR, UV–Vis spectroscopy, revealing formation both SC aryl alkyl bonds. Thermal morphological analysis (via TGA, DSC, PXRD, SEM‐EDS) indicated has higher crystallinity thermal stability than attributed to a degree crosslinking greater content dark sulfur. Mechanical testing showed exhibits superior compressional flexural strengths, enhanced Young's modulus Shore hardness, compared . Notably, mechanical strength parameters for are comparable those C62 class bricks used in construction applications. These findings suggest that composites, particularly incorporating syringol, can provide viable alternatives traditional materials various applications, contributing waste sustainable science.

Fine root decomposition is a physio-biochemical activity that critical to the global carbon cycle (C) in forest ecosystems. It crucial investigate mechanisms and factors control fine ecosystems understand their system-level balance. This process can be influenced by several abiotic (e.g., mean annual temperature, precipitation, site elevation, stand age, salinity, soil pH) biotic microorganism, substrate quality) variables. Comparing rates within sites reveals positive impacts of nitrogen phosphorus concentrations negative effects lignin concentration. Nevertheless, estimating actual breakdown difficult due inadequate methods, anthropogenic activities, impact climate change. Herein, we propose how physiochemical characteristics interact with microorganisms influence decomposition. review summarized elements this process, as well research methods used it.

<p>Lignin, the most abundant natural aromatic compound on earth, offers valuable resources for development of bio–based polymers. In recent years, a plethora diverse polymer materials has been reported using either separated lignin or lignin–derived monomers. this review, we present comprehensive summary achievements and compare these two well–known strategies. While utilizing directly as starting advantages in terms cost–effectiveness wider options, employing monomers suffer from higher costs limited structural variety. However, well–defined structure lignin-derived monomers, retention functional group characteristics make promising strategy future applications. Through review paper, aim to inspire more researchers material science focus lignin—an intriguing emerging carbon-neutral biomaterial.</p>

Abstract Bone regeneration for large, critical-sized bone defects remains a clinical challenge nowadays. Guided (GBR) is promising technique the repair of multiple defects, which widely used in oral and maxillofacial but still unsatisfied treatment long defects. Here, we successfully fabricated bilayer mineralized collagen/collagen (MC/Col)-GBR membrane with excellent osteoinductive barrier function by coating MC particles prepared via situ biomimetic mineralization process on one side sheet-like pure collagen layer. The aim present study was to investigate physicochemical properties biological functions MC/Col film, further evaluate its efficiency large defect repair.

Lignin is an abundant polyaromatic polymer with a wide range of potential future uses. However, the conversion lignin into valuable products comes at cost, and medium- to high-value applications are thus appropriate. Two examples these polymers (e.g., as fibers, plasticizers, or additives) flow batteries redox species). Both areas would benefit from lignin-derived molecules potentially low molecular weight high (electro)chemical functionality. A promising route obtain oxidative depolymerization, it enables formation targeted compounds multiple functionalities. An application in production plastics synthesis new sustainable polymers. Employing organic molecules, such quinones heterocycles, constitute important step toward sustainability aqueous batteries, its derivatives emerging species, mainly due their cost renewability.

Benzene, toluene, and xylenes (BTX), as well their downstream products, are a fundamental part of numerous processes in the chemical industry. However, by now, aromatics still yielded from fossil resources like naphtha, coal, natural gas. Thus, to push industry further toward renewability, production bio-based is an essential step take. The implementation replace petrochemical can proceed two main ways: direct replacement via renewable drop-in or functional alternatives. both pathways requires significant process optimization large-scale application industrial processes. In this work, mainly discussed context pyrolysis Diels-Alder reactions. Furthermore, alternatives here focus on furan derivatives lignin-based building blocks.
