Abstract Wood pulp fibres are promising reinforcements for biocomposites due to their renewable resource origin and mechanical properties. An oriented dense fibre reinforcement structure is beneficial biocomposite We present a method of modifying (e.g. increase strain failure) in pre-formed high-density paper structures intended or as hot-pressed materials. Mildly delignified, well-preserved ho...
In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...
As the second largest production material, starch has important value in textile, food, chemical and other fields. The shortcomings of natural can be solved, its properties improved by modifying structure, developing original properties, or introducing new functions, making it more suitable for certain application requirements. At present, methods modification mainly include chemical, physical,...
Acoustic cavitation has been shown to cause physical damage and partial starch depolymerization in ultrasound-treated flours. However, the promising effects of this modification on bread-making performance gluten-free flour are still unexplored. Based hypothesis, sonicated rice (2–20 min) was used replace 30% native control formulation bread. Breadmaking characterized by doughs' pasting, therma...
