Los mejillones verdes asiáticos (Perna viridis) son bivalvos que se adhieren firmemente a las rocas en las costas intermareales golpeadas por las olas a través de una secreción proteica. Los mejillones de P. viridis siguen una secreción de proteínas adhesivas regulada en el tiempo, donde la proteína del pie-5 de P. vi…
The study presents a methodology for the optimum selection of the most suitable zinc-based coatings in metallic trunking systems to fulfill the requirements related to atmospheric corrosion resistance. The current methodologies are based on heuristic procedures that do not consider the influence of the in situ atmosph…
Nanotechnology, the widely expanding branch, deals with the study of the properties, applications, and toxicity of particles of smaller dimensions particularly less than 100 nm. This chapter provides a brief introduction to the exciting world of nanoscience and its importance in study. This chapter also provides an ov…
We report on the interplay between surface morphology and the magnetic properties of Pt/Mn ultra-thin bilayers by measuring the temperature dependence of the resistivity of Hall bars cooled under application of an external magnetic field. The resistivity ( ρ ) versus temperature ( T ) curves measured under a magnetic…
The chapter deals with the phenomenon of corrosion of mild steel, its causes, consequences, and inhibition by means of phytochemicals. Corrosion is a major hazard in the application of metals in various fields and its inhibition is to be addressed for rapid and smooth progress in civil, industrial, transport, and othe…
The possibility of an inhomogeneous charge density wave phase is investigated in a system of two coupled electron and hole monolayers separated by a hexagonal boron nitride insulating layer. The charge-density-wave state is induced through the assumption of negative compressibility of electron/hole gases in a Coulomb…
Fly ash merupakan limbah pembakaran batu bara yang memiliki kandungan kimia berupa silika dan alumina mencapai 80%. Senyawa tersebut bereaksi dengan Ca(OH)2 hasil proses hidrasi semen dan membentuk C3S2H3 atau tubermorite yang dapat menambah kekuatan beton. Penggunaan fly ash dalam jumlah besar yaitu 50% subtitusi sem…
Silver (Ag+) doped phosphate glass after exposure to ionizing radiation has an intense luminescence by stimulating with ultra-violet light. This phenomenon is called radiophotoluminescence (RPL). The RPL intensity was increased linearly with increasing X-ray irradiation dose up to about 1000 Gy. Small amount of bead-t…
Common failures in road asphalt pavement includes fatigue, rutting and cracking. It is also common that these failures are usually resulted from either temperature sensitivity or moisture susceptibility of asphalt mix or one of its component – asphalt or aggregate. Many studies have recently dealt with these problems…
The microstructure and mechanical properties of 2205 duplex stainless steel (DSS) during long-term aging at 500°C were studied. The results showed the hardness of specimens increased all the time during aging, reach the peak with aged for 5800h. Besides, aging at 500°C led to a significant decrease in toughness and no…
The infrared transmitting electromagnetic interference shielding (Infrared-EMI) filters were fabricated through transferring multilayer graphene on ZnS and As40Se60 infrared substrates. The monolayer graphene was grown by chemical vapor deposition (CVD) catalyzed by copper foil. The carrier mobility of monolayer graph…
The author has investigated the process to obtain zirconium (IV) oxymethanesulfonate via the interaction between methane sulfonic acid (CH3SO3H) (MSA) and zirconium (IV) oxocarbonate (ZrOCO3.nH2O), and explored its basic physical-chemical and technological properties. The research was undertaken to address the lack of…
Elastic modulus was applied to estimate the damage variable based on continuum damage mechanics. A damage evolution equation was derived and the variation of damage characteristics with deformation was also discussed. Repeated loading-unloading tensile tests were conducted on 5052 aluminium alloy. It was found that th…
Antennary oligoglycines are synthetic products, obtained as a result of preliminary molecular design. Equal-length antennae are built of glycine residues joined through the C end to an oligoamine branching core with an amine group at the N terminus exposed outside. The results of systematic research on the properties…
There is a growing interest in epitaxial interfaces between nonisostructural transition-metal oxides that might exhibit interfacial correlated-electron effects. In this study, we show at the atomic scale that a fully coherent and very stable interface between rutile-type TiO 2 and corundum-type Ti 2 O 3, namely (100)…
In this paper, the poly 3,3'-dimethylglutaric acid neopentane diol ester and poly (3,3'-dimethyl glutaric acid 1115 ester) were synthesized. The PU damping material was obtained by preparing prepolymer synthesized with above materials and 2,4-toluene diisocyanate or isophorone diisocyanate, and taking 3,3'-di chlorine…
Strong correlations between phonon energies and superconducting transition temperatures can be extracted from phonon dispersion calculations using density functional theory for a range of superconducting materials. These correlations are robust and consistent with experimental data for key external conditions includin…
A novel rare earth activated phosphor Ca 1-x-y Al 2 Si 2 O 8 :xCe 3+ , yTb 3+ were prepared under a weak reducing atmosphere by conventional solid-state reaction method and their luminescence properties under 351 nm excitation were investigated in detail. The results show that the CaAl 2 Si 2 O 8 : Tb 3+ shows excited…
Theoretical and experimental characterization methods have been combined to shed more light on the potential impact of the various templating amines that they may have on the formation of layered vanadates with a scroll morphology and their cation-exchange capacity. Eight branched- and straight-chain alkylamines were…
