Abstract ：
Increasing kraft pulp yield has long been a critical objective in the pulp and paper industry. In recent years, methyl mercaptan (MeSH) has been recognized as an effective additive for enhancing kraft pulping yields in both softwood and hardwood. To elucidate the underlying mechanisms, this study investigates the impact of MeSH introduction on bamboo kraft pulping, with a focus on understanding its role in enhancing delignification efficiency and protecting carbohydrates. A comparative analysis on kraft lignin reveals that MeSH introduction significantly reduces lignin's molecular weight by approximately 30%, and the phenolic hydroxyl group content drastically increases by 21.7%. That promotes the dissolution of kraft lignin in pulping liquors, thus accelerating delignification and shortening H-factor by 29.5% and lowering alkali charge by 2%. Analysis of polymerization degree (with a 56% reduction in its decrease) and reducing end group content (decreasing by 12%) in cooked dissolving pulps verifies that MeSH inhibits both carbohydrate peeling reactions and alkaline hydrolysis, and the primarily contribution is on the protective effect on cellulose (82.1%). Therefore, we believe that the main mechanism using MeSH as additives includes two aspects, i.e., accelerating delignification and preventing carbohydrate degradation, which collectively promotes the yield increase of bamboo kraft pulp by 2.8%.

Abstract ：
有机太阳能电池（OSCs）具有成本低、可大规模溶液加工、轻量化和柔性等优势，近年来已引起人们的广泛关注，当前OSCs的最高光电转换效率已超过19%。然而，绝大多数OSCs材料主要是采用化石资源衍生物制造，这对OSCs的可持续发展构成了严重威胁。研究者已开展了大量关于生物质基光电材料的开发工作，并成功将这些材料用作OSCs的衬底、光敏活性层与载流子传输层。本文首先对OSCs的器件结构和工作原理进行了介绍，重点对木质素、纤维素、叶绿素等生物质基光电材料的制备及其在OSCs中的应用展开综述，最后对生物质基OSCs材料的发展方向做出了展望，旨在为后续的相关研发工作提供借鉴。

Abstract ：
Woodwork has functions as the versatile and sustainable furniture material to decorate buildings in our lowcarbon society, while commonly giving significant risks of releasing volatile organic compound (VOC). Thus, how to accurately identify and quantify the VOC of woodwork raw materials is critical. Herein, we designed an easy-to-handle, processable, time-saving strategy of coupling headspace (HS) and gas chromatography (GC) to effectively and precisely investigate the emission behavior of VOC of Cinnamomum camphora (C. camphora). The effects of operation parameters of HS-GC on the VOC emission are analyzed in detail, where the optimize treatment conditions are 140 degree celsius of equilibrium temperature, 25 h of equilibrium time, and 20-40 mesh of particle size. In addition, camphor and eucalyptol are the main chemical components of VOC, which shows the high content, more than 50 % of harvesting VOC. Moreover, a semi-empirical model for VOC emission of C. camphora is established, in which the predicted VOC emission demonstrates a strongly linear relationship with the experimental results (R-2 > 0.99). This study enables the comprehensive understanding of VOC emission of raw materials of woodwork, beyond C. camphora, and provides references to effectively reduce VOC in sustainably building and construction.

Abstract ：
The pulp industry, one of the oldest and largest chemical industries globally, plays a critical role in biomass utilization. Increasing kraft pulp yield has long perplexed researchers and engineers. Given that methyl mercaptan (MeSH) can be self-produced during the kraft pulping process, revisiting MeSH-assisted yield enhancement technology offers great attraction for pulp industry. MeSH's strong nucleophilicity enables its consumption through both demethylation and non-demethylation reactions. Investigating the MeSH's evolution at typical pulping conditions is crucial for achieving higher recovery rate of MeSH. This study found that higher pulping temperatures, increased alkali charge, and larger Na2S ratios improve the recyclable residual MeSH content in black liquors, increasing it from 17 to 36%. Under moderate pulping conditions, the residual MeSH content was approximately 30% of the original MeSH. Dimethyl sulfide (DMS), a valuable demethylation product of lignin or hemicellulose by MeSH, was found in black liquors at levels up to 15% of the original MeSH. Approximately half of MeSH participated in non-demethylation reactions and could not be recycled. X-ray photoelectron spectroscopy (XPS) analysis of separated kraft lignins suggested the generation pathway and chemical structure of new methylsulfur (MeS)-containing lignin. For economic balance and profitability, DMS recycling is proposed as cost compensation, or by adopting partial MeSH-assisted kraft pulping in batch digesting systems.
