With the purpose to replace expensive and significantly cytotoxic positively charged polypeptides in biodegradable capsules formed via Layer-by-Layer (LbL) assembly, multilayers of bovine serum albumin (BSA) and tannic acid (TA) are obtained and employed for encapsulation and release of model drugs with different solu…
Design of functional hybrids lies at the very core of synthetic chemistry as it has enabled the development of an unlimited number of solids displaying unprecedented or even improved properties built upon the association at the molecular level of quite disparate components by chemical design. Multifunctional hybrids a…
Electrospun nanofibers that contain silver nanoparticles (AgNPs) have a strong antibacterial activity that is beneficial to wound healing. However, most of the literature available on the bactericidal effects of this material is based on the use of AgNPs with uncontrolled size, shape, surface properties, and degree of…
Poly(lactic acid) (PLA), one of the widely studied renewable resource based biopolymers, has yet to gain a strong commercial standpoint because of certain property limitations. This work is a successful attempt in achieving PLA biocomposites that showed concurrent improvements in impact strength and heat deflection te…

Cellulose based hybrid composites are gaining popularity in the growing green communities. With extensive studies and increasing applications for future advancement, the need for an accurate and reliable guidance in machining this type of composites has increased enormously. Smooth and defect free machined surface are…
We report that when (La,Sr)MnO3 films grown on orthorhombic (110)o DyScO3 (DSO) substrates once reach a critical thickness, anisotropic patterned cracks are introduced which propagate parallel to [1–10]o direction. The typical surface morphology and cross-sectional TEM are examined in order to clarify the formation of…
A facile method for surface modification of graphene nanoplatelets (GNPs) in the presence of chitosan was developed to improve their interfacial interaction and dispersion within polymer matrix. The selection of a suitable organic dispersant for GNPs was performed using a sedimentation test of the GNPs in different or…
Micro-/nano-sized BaFe12O19particles were synthesized by the hydrothermal method, and the effects of Ba/Fe ratio, OH-/Cl- ratio, reaction time, and reaction temperature on the phase composition, static, and millimeter (mm)-wave magnetic properties of BaFe12O19were studied. Phase composition analysis shows that non-sto…
Abstract Waterflooding with seawater is the most common approach to supporting reservoir pressure and stimulating oil production in offshore installations. However, producing wells can be significantly damaged when seawater breakthrough occurs, as BaSO4 scale can deposit in the near wellbore area; especially for wells…
Electron probe microanalysis (EPMA) is based on the comparison of characteristic intensities induced by monoenergetic electrons. When the electron beam ionizes inner atomic shells and these ionizations cause the emission of characteristic X-rays, secondary fluorescence can occur, originating from ionizations induced b…
Abstract The thermal shock resistance (TSR) of ZnS wave-transparent ceramic depends on not only the mechanical and thermal properties of materials, but also the aerodynamic heating, pneumatic pressure, external constraint, size, aspect ratio and other factors in its actual service process. The theoretical model was es…

Modeling of self-diffraction pattern formation from the induced diaphragm, arising in the case of the transparency channel saturation by one-photon resonant non-stationary excitation of the basic exciton transition in colloidal quantum dots (QDs) is realized. The simulation results allow us to obtain the reference ima…
In the last years, the number of products for oral care has been expanded to adapt to consumer needs. Thus, in addition to conventional products, new “pocket products” such as sugar-free chewing gums and oral strips (OS) have been developed for oral care. In the present study, OS were formulated using chitosan as the…

Nanoparticles presents the remarkable variety of nanoparticle families, compositions, structures, and functions. The book discusses nanoparticles made of semiconductors, metals, metal-oxides, organics, biological and hybrid constituents. Through a wealth of examples and case studies, supplemented by numerous figures,…
The mechanism for the fast switching between amorphous, metastable, and crystalline structures in chalcogenide phase-change materials has been a long-standing puzzle. Based on first-principles calculations, we study the atomic and electronic properties of metastable Ge2Sb2Te5 and investigate the atomic disorder to und…
Surface preparation has been identified as one of the most critical aspects of attaining predictable and reliable adhesive bonds. Energetic processes such as laser ablation or plasma treatment are amenable to automation and are easily monitored and adjusted for controlled surface preparation. A laser ablation process…
Transparent and colorless CeO2-activated borogermanate glasses with about 5.60 g/cm3 were successfully synthesized by a melt-quenching method in air atmosphere. Both the optical transmittance and X-ray absorption near edge spectroscopy (XANES) spectra confirm that Ce4+ can be effectively reduced to its trivalent state…
