Tannin, after lignin, is one of the most abundant sources natural aromatic biomolecules. It has been used and chemically modified during past few decades to create novel biobased materials. This work intended functionalize for first time quebracho Tannin (T) through a simple phosphorylation process in urea system. The tannin was studied by Fourier transform infrared spectroscopy (FTIR), NMR, inductively coupled plasma optical emission (ICP-OES), X-ray fluorescence spectrometry (XRF), while further characterization performed scanning electron microscopy/energy dispersive (SEM/EDX) thermogravimetric analysis (TGA) investigate morphology, composition, structure, thermal degradation phosphorylated material. Results indicated occurrence phosphorylation, suggesting insertion phosphate-containing groups into revealing high content phosphate (PT). elevated phosphorus serves as evidence successful incorporation functionalization process. corresponding PT T were employed adsorbents methylene blue (MB) removal from aqueous solutions. results revealed that Langmuir isotherm model effectively represents adsorption isotherms. Additionally, pseudo-second-order indicates chemisorption predominantly controls mechanism. finding also supports fact introduced via significantly contributed improved capacity. Under neutral pH conditions at room temperature, material achieved an impressive capacity 339.26 mg·g

As a versatile nanomaterial derived from renewable sources, nanocellulose has attracted considerable attention for its potential applications in various sectors, especially those focused on water treatment and remediation. Here, we have combined atomic force microscopy (AFM) reactive molecular dynamics (RMD) simulations to characterize the interactions between cellulose nanofibers modified with carboxylate or phosphate groups protein foulant model bovine serum albumin (BSA) at pH 3.92, which is close isoelectric point of BSA. Colloidal probes were prepared by modification AFM nanofibers, nanofiber coating tip was first time confirmed through fluorescence labeling confocal optical sectioning. We found that wet-state normalized adhesion approximately 17.87 ± 8.58 pN/nm carboxylated (TOCNF) about 11.70 2.97 phosphorylated ones (PCNF) studied pH. Moreover, adsorbed partially unfolded interface due secondary structure's loss intramolecular hydrogen bonds. demonstrate colloidal can be used as sensitive tool reveal BSA nano scales under situ conditions. RMD helped gain molecular- atomistic-level understanding differences these findings. In case PCNF, solvated metal ions, preferentially bound phosphates, reduced direct protein–cellulose connections. This lead significant advancements development cellulose-based antifouling surfaces provide crucial insights expanding range use suggesting appropriate recalibrations.

Flexible electrothermal heaters have attracted abundant attention in recent years due to their wide applications, but preparation with high efficiency remains a challenge. Here this work, highly stable and bending-tolerant flexible heater was fabricated graphite nanosheets cellulose fibers through scalable papermaking procedure. Its property can be enhanced by hot-pressing treatment introduction of cationic polyacrylamide (CPAM) during the protocol. The may quickly reach its maximum temperature 239.8 °C around 1 min at voltage 9 V. power density up 375.3 cm2 w−1. It appeared tolerance for bending deformation various curvatures, remained even under 100 frequency 0.17 Hz. Over alternatively heating cooling cycles, it worked stably as well. proved used wearable equipment, soft heaters, aircraft deicing devices, suggesting great prospect field heat management.
