In this study, a double cross-linking strategy was employed using poly(vinyl alcohol) (PVA) and 3-aminopropyltriethoxysilane (KH550) to reinforce cellulose aerogels, forming a stable 3D network through hydrogen and chemical bonding. The resulting aerogel exhibits remarkable mechanical strength, with a compressive stress of 2.16 MPa at 80 % strain, an 854 % improvement over pure cellulose aerogels (CA).

The PVA/KH550 cross-linked aerogel demonstrates excellent acoustic and thermal insulation properties. The PVA/KH550 cross-linked CA effectively attenuates sound transmission with an average sound transmission loss of 34.35 dB across the frequency range of 800–6300 Hz under an intensity of sound source of 85 dB. Additionally, the aerogel exhibits outstanding thermal insulation with low thermal conductivity of 0.0324 W/m·K. The aerogel shows a promising potential for robust, energy-efficient, lightweight, fireproof, and sound insulation materials.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 119985"},"PeriodicalIF":5.6,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The co-pyrolysis of IHS and RSO can increase the content of alkene, alkane and MAHs, which improve the quality of bio-oil significantly.

Wood formation is derived from the periodic changes of cambial activity that is regulated by environmental cues and phytohormone signals. Brassinosteroids (BRs), a class of plant-specific steroid hormones, play central roles in modulating cambial activity and xylem development. To decipher the regulatory role of BR in the dynamic change of Chinese fir cambium, a comprehensive analysis of the transcriptome, targeted metabolome, and anatomical observation was conducted. The application of 24-epibrassinolide (EBR, 10 μM) significantly increased the cambial cell layers, resulting in the thickening of the secondary xylem. Conversely, brassinazole (Brz) treatment strikingly inhibited the xylem development by attenuating cambial activity. Moreover, 1583 up-regulated differentially expressed genes (DEGs) were shared in stages A (reactivating), C (active), and E (dormant), which were annotated into the xylem formation and BR signaling pathway. Metabolomic profiling of phytohormone indicated that the contents of brassinolide (BL, the most active BR), castasterone (CS), and typhasterol (TY) were distinctly increased in stage C. Furthermore, <em>ClBES1/BZR1</em>, a hub gene in the co-expression network, dramatically activated the expression of <em>ClPAL2</em> and <em>ClMYB4</em> by binding to their promotors.

Biodiesel production in Brazil (specially soybean oil biodiesel) has been growing every year and demanding more effective and sustainable technologies, which is the case of enzymatic processes. Enzymatic degumming could be an alternative to provide better quality products, before biodiesel production but also, in a one reaction step as a proposal to reduce time and costs. Therefore, this work was aimed at evaluating enzymatic degumming (previously optimized) of crude soybean oil using a phospholipase cocktail associated with transesterification using lipase from <em>Aspergillus oryzae</em> for ethyl biodiesel production. For this, transesterification was optimized for ethanol:oil (E:O) ratio, water and lipase % through a central composite rotatable design (CCRD). Optimal conditions were used to evaluate two degumming-transesterification associated processes: i) a one-pot reaction (OPR) where degumming and transesterification were performed at the same reactor; and ii) a two-pot reaction (TPR) where oil was first degummed, followed by transesterification. The optimal transesterification condition were achieved for E:O = 4.48:1, water = 3.41 % and lipase = 2.43 %, where 97 % fatty acid ethyl esters (FAEE) were obtained. Both OPR and TPR provided biodiesels with FAEE &gt; 94 %: TPR was the best with 97.5 % and 99.98 % before and after biodiesel purification. Mineral elements (including phosphorus) and other impurities (anions) were low, and within quality standards. Glycerol produced also presented very low content of impurities which is quite advantageous. Although lipase achieves good conversion to FAEE (95.7 ± 0.29 %) using crude oil (Control), the final biodiesel carries many impurities (P=80.07 ± 0.1 mg/kg), thus requiring subsequent biodiesel purification steps. In addition, the high impurity content generates a biodiesel that does not comply with ANP legislative standards, P&lt;10 mg/kg. The use of enzymatic degumming in the biodiesel production process generates a biodiesel with low impurities and higher final quality, in addition to being a process that generates less effluent. Enzymatic degumming was essential for obtaining high quality biodiesel and its association with transesterification showed to be a great option for decreasing time and costs for biodiesel production.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 119930"},"PeriodicalIF":5.6,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
