in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...

novel citric acid modified starch-carboxy methyl cellulose (cmc) -montmorillonite (mmt) bionanocomposite films were prepared by casting method and the effect of mmt on the structural and physical properties of the starch-cmc biocomposites was studied. x-ray diffraction test showed thatstrong polar interactions between the hydroxyl groups present in the starch and cmc chains and in the silicate ...

Belimbing (Averrhoa carambola L.) merupakan salah satu buah tropis yang mempunyai umur simpan pendek yaitu sekitar 2-3 hari. Masalah terjadi pada belimbing saat distribusi adalah karena faktor benturan dan penyakit dapat merusak belimbing. Tujuan dari penelitian ini untuk mendapatkan konsentrasi penambahan pektin nanopartikel ZnO (NP-ZnO) terbaik dalam pembuatan bionanokomposit mempertahankan k...

Hydroxyapatite (HA) is a bioceramic very similar to the mineral component of bones and teeth. It well established that osteoblasts grow better onto HA-coated metals than on alone. Herein, preparation new system consisting magnetite (Fe3O4) HA functionalized with oleic acid simvastatin (SIMV), incorporated in chitosan (CHI) scaffolds, was undertaken. synthesized by hydrothermal method, while Fe3...
