Biomimetic trace metals improve bone regenerative properties of calcium phosphate bioceramics
( John Wiley and Sons Inc , 2021 , Article)The bone regenerative capacity of synthetic calcium phosphates (CaPs) can be enhanced through the enrichment with selected metal trace ions. However, defining the optimal elemental composition required for bone formation ... -
CFD modeling of particle settling in drilling fluids: Impact of fluid rheology and particle characteristics
( Elsevier B.V. , 2021 , Article)The settling of drilling cuttings is important for the drilling and clean-out operations. The current article provides a Computational Fluid Dynamics (CFD) modeling study of particle settling behavior during the drilling ... -
Composition and characteristics of trabecular bone in osteoporosis and osteoarthritis
( Elsevier Inc. , 2020 , Article)Background Bone strength depends on multiple factors such as bone density, architecture and composition turnover. However, the role these factors play in osteoporotic fractures is not well understood. Purpose The aim ... -
Glycoside-based niosomal nanocarrier for enhanced in-vivo performance of Cefixime
( Elsevier B.V. , 2016 , Article)This study aimed to evaluate the potential of a novel glycoside non-ionic surfactant synthesized and characterized in our laboratory for increased oral bioavailability of Cefixime. The surfactant was synthesized by simple ... -
Highly dispersed Pt nanoparticles on ultrasmall EMT zeolite: A peroxidase-mimic nanoenzyme for detection of H2O2 or glucose
( Elsevier Inc. , 2020 , Article)In past decade, Pt-based nanomaterials as peroxidase mimics have attracted much attention for H2O2 and glucose detection. However, easy aggregation of Pt nanoparticles (Pt NPs) greatly decreases their peroxidase-like ... -
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
( Elsevier B.V. , 2016 , Article)In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ... -
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore strengthening: A review
( Elsevier B.V. , 2020 , Article Review)Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods ... -
Possible evidence for the existence of a hairy layer at the surface of polymer latex particles
( John Wiley & Sons, Ltd. , 1998 , Article)In this work, an attempt is made to verify the existence of a hairy layer at the surface of polymer latex particles, and determine its thickness under different conditions. Two systems have been studied. In one system, ... -
Prevalence of microplastics in the marine waters of Qatar
( Elsevier Ltd , 2016 , Article)Microplastics are firmly recognized as a ubiquitous and growing threat to marine biota and their associated marine habitats worldwide. The evidence of the prevalence of microplastics was documented for the first time in ... -
Spray-Dried Proliposome Microparticles for High-Performance Aerosol Delivery Using a Monodose Powder Inhaler
( Springer New York LLC , 2018 , Article)© 2018, American Association of Pharmaceutical Scientists. Proliposome formulations containing salbutamol sulphate (SS) were developed using spray drying, and the effects of carrier type (lactose monohydrate (LMH) or ... -
Synthesis of Podlike Magnetic Mesoporous Silica Nanochains for Use as Enzyme Support and Nanostirrer in Biocatalysis
( American Chemical Society , 2020 , Article)Magnetic mesoporous materials have attracted great interest due to their combined property of magnetic nanomaterials and mesoporous materials as well as their potential applications in catalysis, bioenrichment, drug delivery, ...
