Cellulose Microfibril Angle in Wood and Its Dynamic Mechanical Significance [PDF]
, 2013 إن اتجاه اللييفات الدقيقة السليلوزية في طبقات S2 من جدران الخلايا من الخشب اللين له تأثير كبير على الخواص الميكانيكية للخشب. تم العثور على الزاوية بين لييفات السليلوز ومحور الخلية الطولي، وزاوية اللييفات الدقيقة، MFA لتكون عاملاً حاسماً في تحديد الخصائص الفيزيائية والميكانيكية للخشب (Cave، 1997). لهذا السبب، تم توجيه جهد كبير نحو قياس MFA السليلوز.

Radial Variation in Microfibril Angle of Super and Common Teak Wood
Indonesian Journal of Forestry Research, 2008 Teak wood (Tectona grandis L.f.) is a well known and relatively slow growing hardwood species and popularly used as furniture and construction timber. Recently fast growing teak has been introduced which is named as super teak, as opposed and existing common teak. The quality of super teak however, is being questioned and suspected to be not as common

Polymer 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 ...

Measuring the distribution of cellulose microfibril angles in primary cell walls by small angle X-ray scattering [PDF]
Plant Methods, 2014 Background X-ray scattering is a well-established method for measuring cellulose microfibril angles in secondary cell walls. However, little data is available on the much thinner primary cell walls. Here, we show that microfibril orientation distributions can be determined by small angle X-ray scattering (SAXS) even in primary cell walls.

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing
High Voltage, EarlyView.ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic
