The development of sustainable and effective methods for extracting lignin is crucial achieving the advantages promoting shift towards a more circular bioeconomy. This study addresses use environmentally friendly processes, including organosolv technique, supercritical fluid (SCF), non-thermal plasma (NTP), ionic liquids (ILs), deep eutectic solvents (DES), microwave assisted extraction (MAE) techniques extraction. Organosolv treatment offers high selectivity purity make this process economically feasible. Using water, carbon dioxide, or ethanol to extract without harmful successful customizable. NTP technologies break down lignin, simplifying processing increasing its value. Whereas ILs may boost synthesis change properties via solvent design. DES-based can efficiently specifically lignin. rapid MAE method employs radiation reduce times yields These feature selectivity, little environmental impact, capacity target fractions. describes fundamentals, benefits, drawbacks each process, focusing on their ability large scale future usage.

Natural wood has served as a foundational material for buildings, furniture, and architectural structures millennia, typically shaped through subtractive manufacturing techniques. However, this process often generates substantial waste, leading to inefficiency increased production costs. A potential opportunity arises if complex can be created additive processes. Here, we demonstrate an additive-free, water-based ink made of lignin cellulose, the primary building blocks natural wood, that used three-dimensional (3D) print architecturally designed via direct writing. The resulting printed structures, after heat treatment, closely resemble visual, textural, olfactory, macro-anisotropic properties, including mechanical wood. Our results pave way 3D-printed wooden construction with sustainable pathway upcycle/recycle

Abstract Bio‐based hydrogels, valued for their flexibility, tunable mechanical properties, and biocompatibility, are promising materials wearable skins sensing devices in bionic hand control systems. Lignin, a biopolymer rich functional groups, can be modified into UV‐curable monomers, enabling the development of 3D‐printed hydrogels via photopolymerization. However, inherent rigidity lignin's aromatic rings, coupled with covalent cross‐linking between lignin other often limits hydrogel's stretchability (poor strain) compressibility. Additional challenges, including poor moisture retention freeze resistance, further hinder wider application. In this study, lignin‐based hydrogel is developed high tensile strain (≥350%), compressive (≈95%), fatigue resistance (up to 10 000 cycles under 50% strain, 200–800 95% strain), which achieved by incorporating glycerol lithium chloride facilitate dynamic hydrogen ion bonds, while accordingly reducing sites monomers. The enhanced allow effective performance at −40±1 °C. Afterward, using 3D printing technology, sensors ripple‐shaped 3 × Matrix pressure fabricated, demonstrated uniform stress distribution improved controlling complex movements, underscoring application advancing human–machine interfaces.

Abstract Accurate dosing for various liquids, especially highly viscous is fundamental in wide‐ranging from molecular crosslinking to material processing. Despite droppers or pipettes being widely used as pipetting devices, they are powerless quantificationally splitting and liquids (>100 mPa s) like polymer due the intertwined macromolecular chains strong cohesion energy. Here, a transparent photopyroelectric slippery (PS) platform provided achieve noncontact self‐splitting with viscosity high 15 000 s, just assistance of sunlight cooling source provide local temperature difference ( ΔT ). Moreover, guarantee accuracy (>80%), ultrathin MXene film (within thickness 20 nm) self‐assembled photo‐thermal layers, overcoming trade‐off between transparency photothermal property.
