Chemical composition, anatomy, lignin distribution, and cell wall structure of Malaysian plant waste fibers

Chemical Composition, Anatomy, Lignin Distribution, and Cell Wall Structure of Malaysian Plant Waste Fibers

The chemical composition, anatomical characteristics, lignin distribution, and cell wall structure of oil palm frond (OPF), coconut (COIR), pineapple leaf (PALF), and banana stem (BS) fibers were analyzed. The chemical composition of fiber was analyzed according to TAPPI Methods. Light microscopy (LM) and transmission electron microscopy (TEM) were used to observe and determine the cell wall st...

Anatomy, Cell Wall Ultrastructure and Inhomogeneity in Lignin Distribution of Broussonetia Papyrifera

Broussonetia papyrifera (Linn.) Vent has been attracting interest recently as a valuable wood source for pulping and papermaking manufacturing. The present study aims to determine the anatomical structure, ultrastructure and distribution of lignin in the fiber cell walls of this shrub, using electron microscopy, fluorescence microscopy (FM) and confocal Raman microscopy, which, to our knowledge...

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

The Chemical Composition of the Cell Wall of Chlamydomonas Gymnogama and the Concept of a Plant Cell Wall Protein

Cell walls of Chlamydomonas gymnogama, shed during sexual mating, were collected and analyzed. Ultrastructural examination indicates that the walls are free of cytoplasmic contamination and that they exhibit a regular lamellate structure. The walls are composed of glycoprotein rich in hydroxyproline. The hydroxyproline is linked glycosidically to a mixture of heterooligosaccharides composed of ...
