Abstract This study aimed to develop eco-friendly bacterial cellulose (BC) bio-leather with improved durability using plant-based proteins, namely soy protein isolate (SPI) and mushroom (MP), which were physically entrapped inside the BC, respectively. The amounts of proteins determined by evaluating tensile strength BC bio-leather, found be 20 wt% 50 for SPI MP, enhanced properties mechanical ...

Title of Document: SILICON NANOCRYSTALS: BIOCOMPATIBLE FLUORESCENT NANOLABEL Jonghoon Choi, Doctor of Philosophy, 2008 Directed By: Associate Professor, Nam Sun Wang, Department of Chemical and Biomolecular Engineering This study discusses a synthesis, characterization, bioconjugation, and biological responses of fluorescent silicon nanocrystals (SiNCs). First, the efficient method of synthesiz...

objective(s): in recent years, the biosynthesis of gold nanoparticles has been the focus of interest because of their emerging application in a number of areas such as biomedicine. in the present study we report the extracellular biosynthesis of gold nanoparticles (aunps) by using a positive bacterium named streptomyces fulvissimus isolate u from rice fields of guilan province, iran.materials a...

This study examines zinc(II)–chitosan complexes as a bio-sorbent for phosphate removal from aqueous solutions. The bio-sorbent is prepared and is characterized via Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Point of Zero Charge (pHPZC)–drift method. The adsorption capacity of zinc(II)–chitosan bio-sorbent is compared with those of chitosan and ZnO–c...

bovine inorganic biomaterials and correlate them with the dissolution rate. Bio-Oss®, GenoxInorgânico®, and Bonefill® were examined using field emission gun scanning electron microscopy (FEG-SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), specific surface area (BET), calcium/phosphorous molar ratio and a dissolution assay. Bio-Oss® showed a microand nanoporous str...

Bio-oil produced from fast pyrolysis of biomass contains sugars originating from cellulose. Traditional quantification of sugars in bio-oil is accomplished by gas chromatography/mass spectroscopy (GC/MS) via derivatization, high-performance liquid chromatography (HPLC), ion-exchange chromatography (IC), or nuclear magnetic resonance (NMR) methodologies. These techniques are highly specific for ...

New approaches to extracting natural hydroxyl carbonate apatite from bio waste of bovine bones cortical femur have been developed. To extract pure and natural bio ceramics, three different treatments have been applied: 1-Calcination heat treatment at temperature of 700 , 2-alkaline hydrothermal at temperature of 275 and 3-Pressurized low polarity water at temperature of 250 . Raw bovine bone an...

Cracking is one of the main ways that concrete ages, allowing pollutants to seep within and potentially lowering physical mechanical strength endurance structures. One healing procedures merits research use bacterially generated calcium carbonate precipitation in mixtures mend cracks. The impact different variables, including nucleation location, bacterial type, concentration, uratolytic activi...
