Evaluation of Combined Dilute Acid-Kraft and Steam Explosion-Kraft Processes as Pretreatment for Enzymatic Hydrolysis of Pinus radiata Wood Chips

open access: yesBioResources, 2015
The combination of hemicellulose pre-hydrolysis by dilute acid or steam-explosion followed by kraft pulping was one approach evaluated in this work to generate pulps from radiata pine wood chips amenable to saccharification by enzymatic hydrolysis ...

Visual Implied Motion in Marketing: A Dual‐Route Framework of Perceptual Persuasion

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Depicting movement in static marketing stimuli, referred to as ‘implied motion’, is widely used across packaging, logos, and advertising, and multimodal brand communications. Despite growing evidence of its persuasive impact, the underlying psychological mechanisms and boundary conditions remain theoretically fragmented. This systematic review

Ethanol Production from Sugarcane Bagasse Pretreated by Steam Explosion [PDF]

open access: yes, 2013
Bioethanol is an alternative renewable fuel that can be produced from cellulosic biomass through hydrolysis and fermentation based processes. Sugarcane bagasse constitutes a potential lignocellulosic substrate for bioethanol production, since it has high

Exploring biofiber properties and their influence on biocomposite tensile properties

open access: yesPolymer International, EarlyView.
The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...

Bioconversion and characterization of watermelon rind waste‐based microcrystalline cellulose: A green alternative to synthetic reinforcements

open access: yesPolymer International, EarlyView.
Microcrystalline cellulose (MCC) was extracted from watermelon rind using acid hydrolysis. MCC can be efficiently used as reinforcement in biofilms and biocomposites. Abstract The increasing accumulation of agricultural waste from watermelon (Citrullus lanatus) represents a substantial environmental concern, particularly in view of the extensive ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

open access: yesSmall, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

汽爆预处理对油莎豆组分、微观结构 及油脂提取率的影响Effects of steam explosion pretreatment on composition, microstructure and oil extraction rate of Cyperus esculentus

open access: yesZhongguo youzhi
旨在提高油莎豆油的提取率,对油莎豆进行不同时间的汽爆预处理,探究汽爆预处理对油莎豆的化学组分、微观结构以及油脂提取率的影响。结果显示:汽爆预处理使油莎豆的脂溶物和水溶物含量增加,纤维素、半纤维素和果胶含量减少,木质素含量增加;汽爆预处理使油莎豆细胞壁主要化学键发生断裂或修饰;汽爆(30 min)后油莎豆形状发生明显变化,细胞间裂缝变大,细胞结构破损,排列杂乱;汽爆后油莎豆的油脂提取率增至18.41%,比汽爆前(14.58%)提高26.27%。综上,汽爆破壁促进油莎豆油提取的方法是可行的。In order
