<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， DMSO/H<sub>2</sub>O/KOH was used as the solvent to dissolve aramid nanofiber (ANF)/boron nitride nanosheet (BNNS) composite paper， to study the difference in the dissolution rate of ANF/BNNS composite paper with different BNNS contents， and to investigate the micro-dissolution law of ANF/BNNS composite paper. The results showed that the tensile strength of pure ANF paper was 48.8 MPa， the time required to increase from 25 ℃ to 70 ℃ was 6 s， and the dissolution thickness was 42.0 μm， while the tensile strength of ANF/BNNS composite paper with BNNS content of 20% was reduced to 34.5 MPa， and the time required to increase from 25 ℃ to 70 ℃ was only 2 s. The dissolution time was 3 h， and the dissolution thickness was 52.5 μm， which was 25% more than that of pure ANF paper. It was indicated that the addition of BNNS slightly reduced the mechanical strength of the ANF/BNNS composite paper， significantly improved the thermal conductivity of the ANF/BNNS composite paper， promoted the dissolution of the ANF/BNNS composite paper.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， a high-density cationic poly(ionic liquid)-grafted cellulose sponge (CS-PAPIM-co-PBBIM) was fabricated and employed as a novel cellulose-based adsorbent. Two functional ionic liquid monomers， 1-vinyl-3-(3-ammoniumpropyl) imidazolium dibromide and bis-1-vinyl-3，3’-(1，4-phenylmethylene) imidazolium dichloride， were rationally designed and synthesized， and subsequently grafted onto the cellulose sponge surface through reversible addition-fragmentation chain-transfer (RAFT) polymerization. This surface modification markedly enhanced the adsorption performance of the material toward methyl orange (MO). The optimized CS-PAPIM-co-PBBIM exhibited a high adsorption capacity of 312 mg/g for MO. Mechanistic analysis revealed the presence of multiple types of adsorption sites on the adsorption material surface， where electrostatic attraction between the poly(ionic liquid) layer and MO served as the dominant driving force， and π-π stacking interactions together with hydrophobic interactions synergistically facilitated chemisorption. Moreover， after five adsorption-desorption cycles， the adsorbent maintained over 85% of its initial adsorption capacity， demonstrating excellent regeneration ability and cycling stability.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Using alkali lignin as raw material， lignin/copper ion nanoparticles （LNP/Cu） containing rich amounts of ortho-quinone and ortho-phenol were prepared using a self-assembly catalytic oxidation-reduction method. The alkali lignin and LNP/Cu were taken as paper reinforcement， via hot-press drying methods instead of room-temperature drying method to prepare reinforced paper. The effects of the additive and drying methods on paper strength properties were investigated. The results showed that the LNP/Cu prepared in this study exhibited a spherical shape with a diameter of approximately 300 nm and could be uniformly distributed in the paper， demonstrating superior reinforcement effects compared to alkali lignin. The hot-press drying method enhanced the interaction between lignin and fibers. Compared to paper produced without additives and using room-temperature drying， the tensile index， bursting index， and tearing index of the reinforced paper produced with LNP/Cu as an additive combined with the hot-press drying method （120 ℃， 0.14 MPa， 10 min） increased by 27.5%， 51.0%， and 9.6%， respectively， while the air permeability decreased by 38.8%.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study investigated the effects of hydrolysis temperature on the physicochemical properties of hydrolysis residues， hydrolysate， and solid in the hydrolysate during the acetic acid hydrolysis of corn stalk， as well as the soil improvement effects of the hydrolysate on saline-sodic soil. The results indicated that under conditions of acetic acid water-soluble liquid with volume fraction of 20%， a solid-liquid ratio of 1∶10 （g∶mL）， a pH value of 2.4， and a hydrolysis time of 1 h， increasing the hydrolysis temperature promoted the accumulation of sugars in the hydrolysate， with the maximum total sugar （including glucose， xylose， and arabinose） content of 7.34 g/L at 140 ℃； at 160 ℃， the solubility rates of cellulose， hemicellulose， and lignin reached 28.65%， 84.55%， and 16.77%， respectively. Additionally， the hydrolysate contained abundant organic matter and had a low pH value. When diluted 100-fold and used as a soil conditioner for saline-alkali soil， it effectively reduced the pH value， electrical conductivity （EC）， and exchangeable sodium percentage （ESP） of the soil， while increasing the soil organic matter content （SOM）. After three cultivation cycles， the saline-sodic soil transformed from moderately saline-sodic soil to slightly saline-sodic soil， demonstrating significant improvement effects.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Using sunflower stalk rind as raw material， TEMPO/NaBr/NaClO oxidation system was used to prepare TEMPO oxidized cellulose fibers （TOCF）， and further combined with high-pressure homogenization method to obtain TEMPO oxidized cellulose nanofibrils （TOCNF）， which featured with high carboxyl content， small particle size and good dispersion stability. The products was characterized using Transmission Electron Microscopy （TEM）， Fourier Transform Infrared Spectroscopy （FT-IR）， X-ray Diffraction （XRD）， and Thermogravimetric Analysis （TGA）. The results showed that when the dosage of NaClO was 10 mmol/g， the carboxyl content of TOCF reached 1.42 mmol/g. After 8 times of high-pressure homogenization， the length and particle size of TOCNF significantly decreased， with distribution ranges of 100~250 nm and 3~7 nm， respectively. The FT-IR spectrum of TOCF showed a clear —COOH characteristic absorption peak， while TOCNF did not show any new characteristic peaks， indicating that high-pressure homogenization did not change its functional groups. Both TOCF and TOCNF retained the type I crystalline structure of cellulose， but compared with sunflower stalk rind holocellulose， the crystallinity and thermal stability of TOCF and TOCNF had decreased.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To achieve clean and efficient cellulose hydrolysis， a plasma-acid-catalyzed cellulose hydrolysis technical solution with simultaneous acid production and cellulose hydrolysis was proposed. The effects of parameters such as working voltage， discharge gap， and reaction time on cellulose hydrolysis were examined. Furthermore， a comparative study of two technological solutions， simultaneous and stepwise acid production-cellulose hydrolysis was also carried out. Additionally， the reaction mechanism of acid-catalyzed hydrolysis of cellulose enhanced by electric field and discharge plasma was elucidated. The results indicated that when the reaction time was 60 min， the simultaneous acid production-cellulose hydrolysis scheme increased the cellulose conversion rate by 10.5 percent points compared to the stepwise scheme， increased the average cellulose conversion speed by approximately 32.7%， and reduced the average specific energy consumption by about 83.3%.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Lignin was extracted from black liquor through acid precipitation， and a KOH gradient dissolution was employed to simultaneously achieve lignin fractionation and potassiumization， resulting in the synthesis of small molecular lignin potassium fertilizer (LMWL-K) with a high content of hydrophilic groups， which was subsequently applied in the cultivation of potassium-demanding butterhead lettuce seedlings. The results demonstrated that the small molecular lignin (LMWL) exhibited high contents of phenolic hydroxyl (2.98 mmol/g) and carboxyl groups (2.30 mmol/g). Consequently， LMWL-K achieved a potassium content of 15.9%， significantly higher than that of the full-spectrum lignin potassium fertilizer (10.3%). Hydroponic experiments on butterhead lettuce seedlings demonstrated that the optimal treatment efficacy was observed at an LMWL-K dosage of 150 mg/L. Compared with the control group without addition of potassium fertilizer application， LMWL-K significantly enhanced biomass accumulation， increasing the contents of chlorophyll a， chlorophyll b， soluble protein， and soluble sugar by 22.3%， 48.9%， 231%， and 40.5%， respectively. In addition to LMWL-K serving as a potassium source， the LMWL component in LMWL-K was found to stimulate root tip cell division， promote root development， and enhance nutrient uptake， thereby increasing seedling biomass. Its growth-promoting effects surpassed those of potassium humate and inorganic potassium fertilizers at equivalent potassium concentrations. Furthermore， LMWL-K was shown to regulate osmotic metabolism and activate the antioxidant enzyme system， thereby significantly enhancing the salt tolerance of the butterhead lettuce seedlings.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Deep eutectic solvents （DES） were prepared by combining various organic acids （citric acid， malic acid， and lactic acid） with 2，3-epoxypropyl trimethyl ammonium chloride （molar ratio of 1∶2）. These DES were used to pretreat hardwood chemical pulp to prepare cellulose nanofibers （CNF） with a high-pressure homogenization process. The effects of pretreatment by different DES on the properties of CNF were investigated. The results indicated that the CNF produced using the DES of lactic acid/2，3-epoxypropyl trimethylammonium chloride with homogenizing for 15 times under a pressure of 100 MPa exhibited the best performance， with an average diameter reduced to 12.95 nm， a Zeta potential of -26.21 mV， and no phase separation after 9 months of storage. The analysis of the mechanism revealed that DES selectively broke down the amorphous regions of cellulose fibers after swelling， was conductive to subsequent high-pressure homogenization treatment to produce CNF with a high specific surface area and excellent properties.]]></description>

The adsorption performance of lignin-based porous carbon towards the neonicotinoid insecticide imidacloprid (IMI) in an aqueous solution was preliminarily investigated. The results indicated that staged hydrochloric acid pretreatment at pH value of 9 effectively optimized the pore structure and surface chemical activity of the lignin-based porous carbon (KP9@MBC@N). The specific surface area， total pore volume， and average pore diameter of the resulting KP9@MBC@N were 1 693.8 m<sup>2</sup>/g， 0.56 cm<sup>3</sup>/g， and 2.52 nm， respectively. Under the conditions of IMI solution initial concentration of 200 mg/L， adsorbent dosage of 10 mg， adsorption temperature of 35 ℃ and adsorption time of 120 min， the maximum adsorption capacity of KP9@MBC@N towards IMI could reach 294.4 mg/g. It was hypothesized that the adsorption mechanism towards IMI mainly involved pore filling and some mild chemical reactions.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study mimicked the structure of natural plant cell walls， using cellulose nanofibers （CNF）， konjac glucomannan （KGM）， and sulfonated lignin （LA） as raw materials， a physically cross-linked network was constructed via acetic acid vapor protonation， and by the formation of a chemically cross-linked network using epichlorohydrin and ammonia vapor， resulting in the preparation of two types of cross-linked lignocellulose-based composite films. The study systematically investigated the effects of cross-linking methods and component ratios on the physicochemical properties of the composite films， revealing the synergistic mechanisms of the three components within the composite films. The results indicated that， similar to natural plant cell walls， CNF within the composite film formed a rigid three-dimensional framework through intermolecular hydrogen bonding， KGM enhanced the synergistic effect of hydrogen bonding to improve film toughness， and LA could toughen the film and optimize its pore structure. Compared to the control without LA， when the LA mass fraction was 1%， the fracture strain of the chemically cross-linked composite film increased from 5.01% to 10.65%， and the 1 day water swelling rate was as low as (175.78±11.06)%， which was only 4.12% of that of the physically cross-linked composite film. At a LA mass fraction of 15%， the chemical cross-linked composite film achieved peak blocking rates for medium-wave ultraviolet （UVB） and long-wave ultraviolet （UVA） radiation， at 98.5% and 87.8%， respectively. These results demonstrated that LA not only optimized the pore structure of the composite film and significantly enhanced its mechanical properties but also conferred excellent water resistance and UV shielding performance.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Utilizing sugarcane tops as raw material， a major agricultural waste product in Guangxi， the multi-component decrystallizing depolymerization agent pretreatment effectively disrupted the stable and compact structure of the lignocellulose components in sugarcane tops. Subsequently， the hemicellulose component of sugarcane tops was efficiently separated and extracted via water extraction/alcohol precipitation method. The pretreatment conditions for extracting hemicellulose in the sugarcane tops were optimized through single-factor and orthogonal experiments. The results showed that the optimum extraction process conditions were 200 μL for multi-component decrystallizing depolymerization agent dosage， 35% for sugarcane tops moisture content， 120 ℃ for pretreatment reaction temperature， and 3 h for reaction time. Under the optimized conditions， the extraction yield of hemicellulose from the sugarcane tops reached (14.0±0.5)%. The Fourier Transform Infrared Spectroscopy， Scanning Electron Microscopy， and Thermogravimetric Analysis indicated that the main chemical structure of the extracted hemicellulose from the sugarcane tops was nearly undamaged after multi-component decrystallizing depolymerization agent pretreatment and it exhibited good thermal stability.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study utilized sugarcane bagasse as raw material， employed a pretreatment method combining <i>p</i>-toluenesulfonic acid-alkali-bleach to obtain sugarcane bagasse cellulose (TSA-SCB). Subsequently， oxalic acid hydrolysis was applied to produce sugarcane bagasse cellulose nanocrystal (SCB-CNC). The optimum preparation conditions of both TSA-SCB and SCB-CNC were investigated. The results showed that lignin and hemicellulose from SCB were efficiently removed， and the prepared TSA-SCB had a high purity， when the <i>p</i>-toluenesulfonic acid solution concentration was 65%， reaction temperature was 80 ℃， and reaction time was 20 min. Under the conditions of oxalic acid solution concentration of 90%， hydrolysis temperature of 110 ℃， and hydrolysis time of 3 h， SCB-CNC had a yield of 29.8% with the Zeta potential of -32.65 mV and excellent stability of suspension. The physicochemical properties of SCB-CNC were characterized， the results indicated that SCB-CNC exhibited rod-shaped with an average length and average width of about 468 and 39 nm， respectively， and it was successfully introduced carboxyl groups onto surface of SCB-CNC while retaining the crystalline structure of cellulose type I. Furthermore， SCB-CNC suspensions could self-assemble into a chiral nematic liquid crystal phase at a certain concentration.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， cellulose acetate （SBC-CA， Pre-SBC1-CA， Pre-SBC2-CA） and cellulose benzoate （SBC-CB， Pre-SBC1-CB， Pre-SBC2-CB） were prepared by acetylation （homogeneous） and benzoylation （heterogeneous） reactions， respectively， with sugarcane bagasse cellulose before and after dry pretreatment at different times as raw material. The samples were characterized to investigate the effects of dry pretreatment on esterification activity of sugarcane bagasse cellulose， with their structure and properties. The results showed that dry pretreatment effectively improved the esterification activity of sugarcane bagasse cellulose， and was conducive to the preparation of cellulose acetate and cellulose benzoate with favorable crystalline structure， hydrophobic properties， and thermal stability. Compared with SBC-CA and SBC-CB without dry pretreatment， Pre-SBC2-CA and Pre-SBC2-CB with dry pretreatment for 3 h exhibited the highest esterification efficiency with substitution degrees of 2.82 and 0.76， increased by 20.5% and 46.2%， while yields rose by 1.2 and 1.3 times， the crystallinity index increased by 1.26 and 1.09 times， the water contact angle increased by 74.1% and 20.5%， respectively. Theremore， the temperatures corresponding to the maximum degradation rate of Pre-SBC2-CA and Pre-SBC2-CB reached 380 and 369 °C， with both the initial and complete decomposition temperature increasing simultaneously.]]></description>
