Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Development of Continuous Cooking Process for Kraft Pulping
カミヤ社が1949年に連続蒸解技術を開発して以来,連続蒸解技術が商業的に注目され始め,1980年代に入ると,異なったニーズに応じて多くの連続蒸解システムが開発された。その後,生産規模及び環境保全への対応,蒸解収率の向上,操業の安定化,漂白効率の改善,最終製品の品質要求を満たすパルプ品質確保のために,COMPACT COOKING™の連続蒸解システムが開発された。2000年代になると,パルプ製造の原料である木材チップと重油の高騰から製造コストの低減を目的とした蒸解プロセスを含むプロセス面での改善が試みられている。本稿では,まず連続蒸解釜の変遷,そしてクラフトパルプ法の連続蒸解プロセスの進歩を振り返る。次に1ベッセル気相/液相釜の低温蒸解技術が開発された背景,及びこの技術の特徴について紹介し ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
