“…The physicochemical and mechanical properties of the stem are associated with natural factors (Huda et al 2007), which are reflected in the proportion of holocellulose (cellulose and hemicellulose), lignin, and content of extractives (Rowell et al 2005;Komuraiah et al 2014;Moriana et al 2014). In this study, Ulex europeaus exhibited component values (Table 3) typical of hardwood specimens ( Rowell et al 2005).…”

“…Currently, natural fibers, or biofibers, extracted from plants or cellulose, are widely used for various technological applications. Nontraditional biofibers from renewable sources are a matter of great interest, particularly fibers from sources that have developed an intelligent functional system to adapt to a variety of different climatic and soil conditions (Huda et al 2007).…”

Information on the morphological and physical properties of biofibers is necessary to support the mechanical understanding of the biological design of plants, as well as for the development of new technology that adds value to non-traditional bioresources, such as those based on Ulex europaeus fibers. Ulex europaeus fibers were extracted through a chemical pulping process at 170 °C and with 40 g/L NaOH. The dimensions of the fibers produced were 0.97 ± 0.1 mm in length and 13 ± 2 μm in diameter. Pressed fiber paper sheets were made to evaluate their mechanical properties. Burst and tear indices of 1.2 mN/kg and 8.6 Nm 2 /kg, respectively, were recorded. The values obtained did not compare well to fiber paper sheets from Pinus radiata, presumably due to the significant amount of non-structural elements of wood present in the samples and the lower length of Ulex europaeus fibers, which resulted in lower tensile strength. Additionally, nanoindentation tests were conducted to assess the hardness and elastic modulus of the fibers, obtaining average values of 0.84 GPa and 9.23 GPa for the stem, respectively. These values were significantly lower than those of industrial biofiber, perhaps due to the lower morphogenic maturity of Ulex europaeus fibers compared to other traditional sources of fiber.

“…The properties of natural fibres also depend on their chemical composition [5][6][7]. Over 100 million tons of different synthetic fibres are manufactured every year out of which more than 50% of that is derived from crude oil [8].Therefore, many efforts are made to replace at least a small portion of synthetic fibres with cellulose fibres which are obtained from plants or agro-waste materials. Day by day awareness is increasing in Consumers about environmentally friendly products and more and more people want to buy it [9].…”

Lignocellulosic fibres have been investigated to understand its influence on properties of textile fibres. Pandanus Odorifer (PO) is a leaf fibre which was mechanically extracted from the leaves of the plant using water retting extraction method. The chemical composition of the extracted fibres was determined using TAPPI method. The composition mainly consisted of cellulose 44±1%, hemicelluloses 30±1%, lignin21±1%, ash content 2.5±0.5%, and extractives around 2.5±0.5%, Structural analysis was carried out by FTIR, SEM, TGA, X-ray diffraction. Tensile and moisture content properties were also studied.

“…[1][2][3] Another biomedical application of PLA is its use as a scaffold on which living tissue can regenerate. 3,4 PLA is also important for its relatively new use in textiles such as apparel, indoor, and outdoor furnishings, and hygiene products. [3][4][5][6] Because of the importance of PLA for drug controlled-release, the sorption of drugs onto PLA and their release from PLA have been studied.…”

A method has been developed to predict the percent sorption of small drug molecules onto polylactide (PLA). In this method, molecular modeling is first used to calculate the interaction energy between the adsorbate and PLA. Alternatively, the adsorbate-PLA interaction energy can be calculated by summing the adsorbate functional group contributions to the interaction energy. These functional group contributions have been found in this study. The adsorbate-PLA interaction energy is then substituted into a linear equation to predict the natural log of the sorption equilibrium constant, and the percent sorption is obtained from this value. This linear equation has been developed based on experimental sorption data for dyes on PLA. The predicted percent sorption of two small drugs on PLA has been verified with experimental data. Our method possibly could be used to select appropriate drugs for use in controlled release studies involving PLA. This method also could be used to calculate the functional group contributions to the interaction energies between other drugs and polymers and to predict their percent sorption onto those polymers, which could be used to select drugs suitable for controlled release studies involving those polymers.
