Abstract: Paragrass is a weed of Thailand. It can be applied as reinforcing material for green composites. It was cleaned, soaked in NaOH, washed, dried and ground. The composite sheet was prepared from laminated technique. paragrass were sandwiched between poly(lactic acid) (PLA) sheets then molded by compression in hot press machine at temperature set of 190 degree Celsius. Properties of composite sheet were investigated according to TISI standard No. 876-2532. From the results, Modulus of ruptures, density, water and moisture absorption, thickness swelling and thermal properties were passed the TISI standard.
Keywords: Green composite , Paragrass, Poly lactic acid

| Title | : | Extraction of Dye From Walnut Shell and Dyeing of Natural Fibre |
| Country | : | India |
| Authors | : | Mrs. Alka Ali || Dr. Anita Nishkam |
Abstract: A new natural dye was extracted from walnut shell, then applied to wool and cotton fabric. In this research paper development of a process for the extraction of the natural dyes from inedible walnut shell was investigated. Wool and cotton fabric were selected for dyeing. The study shows that the sources can produce different shades of color with and without mordants. Extraction of dye from the walnut shell through acidic and alkaline medium. The result indicates that the extracted dye through Acidic medium show darker shades were produced on wool fabric as compared to cotton fabric.
Keywords: dyeing, Extraction of dye, mordants, shade.

| Title | : | Dye Selectivity and Colour Fastness Assessment of Dyed icrocrystallineCellulose Extracted From Cornstalks |
| Country | : | Nigeria |
| Authors | : | Adeyemo Bilyaminu Adebola || Yakubu Mohammed Kabir || BelloKasali Ademola || GadimohSylvester |
Abstract: Microcrystalline cellulose (MCC) was extracted from cellulose obtained from cornstalks by sulphuric acid hydrolysis method. The exhaustion dyeing of microcrystalline cellulose with selected commercial dyes; Procion Violet H-3R (reactive), Solophenyl Yellow PFL (direct), and Foron Yellow S.E-2GL (disperse) was carried out and their substantivity were studied from their percentage exhaustions. The percentage exhaustion (% E) of 17.9%, 65.5%, and 75% were obtained for reactive, direct, and disperse dyes, respectively.......

| Title | : | Natural Synthesis of Silver Nanoparticles by Banana Peel Extract and As an Antibacterial Agent |
| Country | : | India |
| Authors | : | Alvakonda Narayanamma |
Abstract: Natural of silver nanoparticles has now become a novel method to physical and chemical approaches. In the present study, silver nanoparticles (AgNPs) were synthesized from banana peel extract (BPE). Our present research is to investigate on the synthesis eco-friendly silver nanoparticles using banana peel extract. In this natural synthesis we used banana peel extract which act as natural reducing agent to synthesize biodegradable silver nanoparticles. Natural silver nanocomposite hydrogels were prepared by a green process using Acrylamide (AM) with banana peel extract........

Abstract: Chitin and chitosan are the second most available biopolymers after cellulose. Chitosan as a result of N-deactylation of chitin and has linear chain of β-(1, 4)-linked 2-acetamino-2-deoxy-β-D-glucopyranose and 2-amino-2-deoxy-β-Dglucopyranose. The chitosan extraction consists of four common steps such as demineralisation, deproteinisation, decolourisation and N-deacetylation. This study on the extraction of chitin and chitosan from the shells of with is golden apple snail shells collection in the control field.........
