Dye-sensitized solar cells (DSSCs) have recently emerged as a low cost option to the more expensive conventional photovoltaic devices based on silicon. However, low efficiency and durability are the recurring problems with DSSCs. In this report, poly(methyl methacrylate) (PMMA) incorporated with carbon dot (CD) is stu…
Stability and hydrophilicity of TiO 2 nano-coating was improved in this work. TiO 2 nanoparticles were prepared via conventional, microwave radiation, surfactant, refrigerating, and silica-assisted sol-gel processes. The coated rock plates were obtained by impregnating the plates with nanofluids. The modified TiO 2 -b…
Abstract On the basis of first principles methods, we systematically investigate the electronic structures and magnetic properties of zigzag C 3 N nanoribbons (ZCNNRs) with ribbon widths (N) from 4 to 12. The unsaturated ZCNNRs are predicted to be magnetic metals or magnetic nearly half-metals depending on the ribbon…
In this paper, nonlocal free longitudinal vibration of thick nanorods is investigated by focusing on the inertia of lateral motions and shear stiffness effects. To this end, Bishop and nonlocal theories are used. Then, by implementing the Hamilton’s principle nonlocal governing equation of motion and boundary conditio…
The local environments within an amphiphilic polymer shell wrapped around lanthanide-doped upconverting nanoparticles were probed using steady-state and time-resolved fluorescence spectroscopy techniques. Emission lifetime measurements of pyrene chromophores trapped within the polymer shell reveal that there are at le…
Abstract Reversible catalytic hydrogenation‐dehydrogenation reactions of ortho ‐terphenyl ( o ‐terphenyl) as one of the most promising materials for hydrogen storage were investigated. The conversion of o ‐terphenyl is 100 % and the selectivity to perhydro‐ o ‐terphenyl reaches 99 % in the first cycle of hydrogenation…
Quantum dots are fluorescent nanoparticles with narrow-band, size-tunable, and long-lasting emission. Typical formulations used for imaging proteins in cells are hydrodynamically much larger than the protein targets, so it is critical to assess the impact of steric effects deriving from hydrodynamic size. This report…
Abstract The present study aims at deposition of zinc phosphate coatings on low carbon steel with incorporated nano- TiO 2 particles by chemical phosphating method. The coated low carbon steel samples were assessed in corrosion studies using electrochemical impedance spectroscopy and potentiodynamic polarization techn…
A series of novel 4f-3d crystalline porphyrinic compounds, {[Co(TPPS)] 2 [Ln(Histidine)(H 2 O)][Ln(H 3 O) 3 ]} n · n H 2 O (Ln = Sm ( 1 ), Eu ( 2 ), Dy ( 3 ); TPPS = 5,10,15,20-tetra(4-sulfonatophenyl)porphyrinato) with TPPS and histidine as mixed ligands, have been prepared and characterized by single-crystal X-ray d…
Pure titanium components fabricated by casting have a coarse grain microstructure. To improve the mechanical strength of pure titanium components by refining the grain size, the cast samples were repeatedly heat-treated. During the heat treatment, the titanium samples were repeatedly heated above the alpha-to-beta ( α…
High Resolution Image Download MS PowerPoint Slide Conjugated porous polymers (CPPs) possess great potential in the energy storage aspect. In this work, a boron-dipyrromethene (BODIPY)-conjugated porous polymer (CPP-1) is achieved by a traditional organic synthesis route. Following this, a carbonization process is emp…
Precise control over microstructure and composition is desired prerequisite for the performance enhancement of thermoelectric materials. In conventional magnetron plasma sputtering synthesis, composition control is challenging when the sputtering-target is composed by different elements. Here, the potential of pulsed…
Spin-crossover (SCO) solids have been studied from magnetic and structural viewpoints under the form of powder, single crystals, and nanoparticles. Recently, an important progress made in chemistry allowed the design of spin-crossover nanocomposites, combining the properties of two types of spin-crossover solids havin…
Abstract Two-dimensional (2D) semiconductors present great potential for electronic and optoelectronic applications due to their uniform thickness and tunable band gaps. Using ab initio electronic structure calculations and quantum transport simulations, we demonstrate the asymmetric metal contact design in the case o…
Skin mechanics is of importance in various fields of research when accurate predictions of the mechanical response of skin is essential. This study aims to develop a new constitutive model for human skin that is capable of describing the heterogeneous, nonlinear viscoelastic mechanical response of human skin under she…
The properties of gelatin films developed from neem extract (NE; Azadirachta indica ) were determined. Moreover, the developed films were applied to minced beef to test its effectiveness for preserving the meat. The quality attributes of the minced beef wrapped with the developed film were monitored over a 7‐day perio…
Shape memory alloys from the Cu–Al–Ni system arouse interest for industrial applications due to their high thermal stability and low cost. In this study, the Cu–11.8Al–3.2Ni–3Mn–0.5Zr alloy is prepared through a powder metallurgy processing technique. Specimens are produced by a conventional uniaxial press followed by…
In this chapter, design and analysis study of thermoelectric cooling systems are described. Thermoelectric (TE) cooling technology has many advantages over the conventional vapor-compression cooling systems. These include: they are more compacted devices with less maintenance necessities, have lower levels of vibratio…
Controlling water vapor diffusion into cellulose–ionic liquid solution induced a novel cellulose complex crystal.
