Microcrystalline cellulose is the most used material for medicine, which able to be found in fibrous plants. Microcrystal celluloses are being used as filler or binder in dosage formulas in tablets and capsules. This research aimed to produce microcrystalline cellulose from ramie based on pharmaceutical grade parameters. Research method include hemp fiber preparation, α-cellulose isolation, microcrystalline cellulose production, and microcrystalline cellulose characterization which compare with Avicel® PH 102 . Result shown microcrystalline cellulose yield is 57.26%. The result of physicochemical characterization that can comply the specifications of pharmaceutical grade as a pharmaceutical excipient.  Keywods :  Microcrystalline cellulose, Ramie, physicochemical, pharmaceutical grade.

This study explores the preparation and application of polyethylene glycol (PEG)-modified PbO2 electrodes. The PEG-modified PbO2 coatings were electrodeposited on a Ti/SnO2-Sb substrate from a methanesulfonate electrolytic bath containing different amounts of PEG. Structural and morphologic characterization was carried out for the deposited electrodes. The presence of PEG in the deposition bath represses the nucleation process and grain growth process in PbO2 deposition. Increasing PEG addition results in an increased [Formula: see text]-PbO2 content and decreased crystallite size. At a limited PEG addition [Formula: see text]4 g/L, a rough and pyramidal surface morphology is presented in the PbO2 coatings. A higher PEG addition at 6 g/L leads to a dense and smooth coating surface yet with less uniformity. Electrochemical characterization reveals a great electrocatalytic activity for the modified PbO2 electrodes when the PEG addition is [Formula: see text]4 g/L.

The purpose of this study was to prepare and characterize solid dispersions of the antibacterial agent Cefdinir with PEG 4000 and PVP K-30 with a view to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obtained showed that the rate of dissolution of Cefdinir was considerably improved when formulated in solid dispersions with PVP K-30 and PEG 4000 as compared with pure drug and physical mixtures. The results from XRD studies showed the transition of crystalline nature of drug to amorphous form, while FTIR studies demonstrated the absence of drug-carriers interaction.
