This review focuses on the progress made over last decade, in development of bio-based matrices for biocomposite applications.
A detailed investigation of the structural changes lithium borate (LiB) glass 25Li2O-(75 - x)B2O3 was conducted in absence and presence lead(II) oxide or aluminum (x = 10 mol %) modifiers. X-ray diffraction (XRD), Fourier transform infrared (FTIR), electron paramagnetic resonance (EPR) spectroscopy were used to explore properties LiB by incorporating trace amounts manganese(III) (0.00-0.25 as a probe. Differential thermal analysis XRD results for glasses their ceramics confirmed integration...
Abstract A novel, bio‐based, aromatic monomer (methacrylated vanillyl alcohol, MVA) is synthesized using alcohol and methacrylic anhydride in the absence of solvents. The resulting MVA used as a sustainable comonomer to replace styrene maleinated acrylated epoxidized soybean‐oil (MAESO) resin produce novel thermosets via free radical polymerization. influence loading on viscosity, gelation time, curing extent, thermomechanical properties, tensile properties MAESO–MVA thermoset investigated....
Soybean-oil-based cationic polyurethane coatings with antibacterial properties have been prepared a range of different molar ratios hydroxyl groups from an amine diol. A second series were soy polyols numbers. All the PU dispersions and films exhibit inhibitory activity against three foodborne pathogens: Salmonella enterica ssp. ser. Typhimurium, Listeria monocytogenes, Staphylococcus aureus. It is generally observed that increases in ratio ammonium cations improve performance. Reduction...
Catalyst deactivation resulting from the hydrothermal leaching of sulfonic acid residues and deposition carbonaceous was studied using condensed phase flow reactor experiments along with state-of-the-art solid-state NMR. Several commercially available acid-containing heterogeneous Brønsted acids were compared by measuring rates breakdown at conditions 160 °C. Amberlyst 45 found to show higher stability when both Nafion 15, <10% loss in acidity after 48 h. The dehydration reaction fructose...
A salt-marsh assemblage of agglutinated foraminifera was recovered from a salt marsh on the east side Tubli Bay in eastern Bahrain. This locality is one last remaining patches coast Bay. The covered by single plant species, Arthrocnemum macrostachyum. Samples were collected beneath canopy two transects beginning at maximum landward extent halophytic plants high and extending to tidal channel seaward low marsh. distinct elevation-related zonation observed trochamminids Entzia macrescens...
The new species Agglutinella kaminskii n. sp. (Miliolida: Siphonapertinae) is described from nearshore marine localities in eastern Bahrain. characterized by its simple tooth and tendency for selectively incorporating colorful siliciclastic mineral grains of eolian origin into test wall. appears to be endemic the Arabian Gulf.
Date palm fiber composites with aligned, continuous fibers and epoxy matrix were prepared mechanically characterized using micromechanical models. A hydrothermal process microwave heating was utilized to extract the date frond (midrib) fibers, making eco-friendly as opposed commonly reported chemical extraction method. Single then found have an average elastic modulus ultimate tensile strength of 17.1 ± 1.5 GPa 333 27.4 MPa, respectively. Interfacial shear strengths ranging between 6 12 MPa...
In this study we report the occurrence of a foraminiferal assemblage dominated by organic-walled agglutinated foraminifera from mangrove swamps located to east Abu Dhabi Island, UAE. Mangals in region are characterized tree Avicennia marina. Different sedimentary facies mangals were sampled for present study. Samples collected upper intertidal area (often dry) proximity marina roots and containing leaf material produced an exclusively composed small-sized opportunistic Ammonia...
In this study, we investigated the relationship between environmental parameters (water and sediment) benthic foraminiferal assemblages found in nearshore siliciclastic sediment Arabian Gulf. Nearshore marine water samples were collected from a beach on Gulf of Bahrain located south Al Khobar, Saudi Arabia. The analyzed for biochemical oxygen demand (BOD5) other chemical analyses. tested (SOD) heavy metal analysis. Results showed BOD5 levels below detection limit (<1 ppm), while mean SOD...
The Paleozoic formations in the Middle East contain some of world's richest petroleum deposits, as they include excellent source and reservoir rocks.The rocks were deposited on northern continental shelf Gondwanan continent at relatively high latitudes, provide evidence Late Ordovician glacial event associated sea-level changes.They also unique fossil remains.The exposed Al-Qassim Province Saudi Arabia are well-suited to become important sites for geotourism.Because sedimentary well-exposed...
NSF Graduate STEM Fellows in K-12 Education (GK12 Fellow) provide students with exposure to inquiry-based learning experiences and authentic demonstrations, which introduce the real-world problems such as renewable energy, sustainable technology. We present a case study on interactions of GK12 Fellow high school chemistry classroom. how experimental design was incorporated into ongoing classroom instruction connected existing curriculum. Evaluations were conducted using pre-and post-test...
