<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study focused on the analysis of the morphological structure， crystalline characteristics， and mechanical properties of the five moraceae phloem fibers (<i>Morus alba</i>，<i> Morus cathayana</i>，<i> Morus australis</i>，<i> Ficus concinna</i>， <i>Ficus heteromorpha</i>). The results indicated that all five moraceae phloem fibers exhibited slender structures， among which the <i>Morus cathayana</i> phloem fiber had the maximum average length (3.02 mm) and the highest aspect ratio (123). The density of these five moraceae phloem fibers ranged from 1.47 to 1.65 g/cm³， all demonstrating high crystallinity (&gt;80%)， with the crystallinity of <i>Ficus concinna</i> phloem reaching as high as 87.42%. Significant differences were observed in their zero-span tensile indices. The <i>Morus alba</i> phloem fiber exhibited the highest dry zero-span tensile index (94.0 N·m/g)， while the <i>Morus cathayana</i> phloem fiber showed the highest wet zero-span tensile index (62.2 N·m/g). Comprehensive evaluation of morphological structure and mechanical properties revealed that <i>Morus alba</i> and <i>Morus cathayana </i>phloem fibers demonstrated superior performance， establishing them as superior raw materials within the pulp and paper industry.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study used a Box-Behnken design and response surface methodology based on a three-variable central composite design to optimize the oxalic acid solution pretreatment process for wheat straw. A mathematical model was established to correlate the glucose conversion rate of wheat straw with pretreatment conditions, and its validity was validated. The results showed that reaction time and temperature during pretreatment were significant factors influencing the enzymatic hydrolysis efficiency of wheat straw. Through response surface analysis optimization, the optimal pretreatment conditions for glucose conversion were identified as follows: a molar ratio of water to oxalic acid of 3.8∶1.0, a reaction temperature of 110 ℃, and a holding time of 20 minutes. Under these conditions, the glucose conversion rate of cellulose reached 95.1%, similar to the model-predicted value (94.5%). Furthermore, the hydrogen production via simultaneous saccharification and fermentation (SSF) of pretreated wheat straw under these conditions achieved 131.5 mL/g, significantly higher than the biohydrogen yield from separate hydrolysis and fermentation (SHF) (105.2 mL/g).]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Cellulose-based porous aerogel composites were prepared from office waste paper and graphene oxide (GO)， followed by amine functionalization of the surface with (3-aminopropyl) triethoxysilane (APTES) to enhance CO<sub>2</sub> capture.In addition， adsorption kinetics， isosteric heat of adsorption， cycling stability， CO<sub>2</sub>/N<sub>2</sub> selectivity， and water uptake were evaluated. The APTES-functionalized cellulose/GO composite aerogel exhibited CO<sub>2</sub> uptaked of 1.2， 1.5， and 2.5 mmol/g at 25 ℃ under 0.001， 0.01， and 0.1 MPa， respectively， with a CO<sub>2</sub>/N<sub>2</sub> selectivity of 87 at 0.01 MPa. The material showed robust cycling performance： only slight capacity fade under pressure-swing adsorption， while complete regeneration was achieved after temperature- and/or pressure-swing desorption.]]></description>
