The raw material used for this NCC production was oil palm empty bunches (OPEFB), currently waste from plantations. Delignification of OPEFB carried out using 2 N NaOH solution at 70oC 6 hours. maximum yield is 62.1% (dry cellulose basis) obtained a concentration 54% sulfuric acid and temperature 50oC. addition plasticizers (glycerol PEG) reduced the elastic modulus capsules 7951.4 MPa to 4758 ...
In this study, we fabricated a cellulose nanocrystal (CNC)-embedded aerogel-like chitosan foam and carbonized the 3D for electrical energy harvesting. The nanocrystal-supported can demonstrate high surface area porosity, homogeneous size ranging from various microscales, quality of absorbing external additives. order to prepare CNC, microcrystalline (MCC) was chemically treated with sulfuric ac...
In this paper, we investigate the electrical conductance and density of states of a nanocrystal including an electrical charge or dipole located at cross section of nanocrystal by using Green’s function method in the nearest neighbor tight-binding approach. The results show that moving the electrical charge from center to the edge of the nanocrystal increases the system transmission coefficient...
