≤ θ, the groove is always wetted; (ii) as , both impregnated and unwetted states can be observed; (iii) as , the groove cannot be impregnated. As the drop volume is increased, both θ and decrease but become insensitive to the volume eventually. Surface roughness tends to hamper the impregnation of grooves by liquid. C…
Nanostructured materials are in the frontline of the present scientific research because of their multifunctional properties that leads their applications from optics to electronic, from mechanical engineering to medical science and technology. However increased levels of nanomaterials in the environment drastically a…
An enantiopure NNN-scorpionate zirconium alkoxide as the highest active group 4-based initiator in ROP of unpurified <italic>rac</italic> -LA under industrially preferred conditions.
Spherical carbon spheres with improved mesoporosity and ion sorption properties are synthesized by an ultrasonic spray pyrolysis process from an aqueous sucrose/NaHCO <sub>3</sub> /TEOS solution.
A supercapacitor based on nitrogen-doped carbon double shell hollow nanoparticles as the electrode material exhibited a high specific capacitance of 202 F g <sup>−1</sup> at a current density of 0.5 A g <sup>−1</sup> due to high surface area and nitrogen-doping.
thin film under gasochromic color switching. Analysis of the V K-edge with respect to crystalline structural symmetry and valence requires many reference samples, whereas the V L-edge, which involves V 3d orbitals of various symmetries, can provide information about the atomic/electronic structures without many refere…
Specific features of complexation in solutions of a strong dibasic acid in the H 2 SO 4 –2-pyrrolidone (Pyr) system (in the range of compositions of 0–100% H 2 SO 4 ) are studied using multiple frustrated total internal reflection IR spectroscopy. The conclusions drawn on the structure of the complexes formed in such…
The relevance of material consumption during the product lifecycle is catching up with that of energy consumption. While the share of renewable energy sources has continuously been rising over the last years, material resources are getting more and more limited on earth. Thus, a method that enables a holistic material…
The inhibition effect of a newly synthesized pyrimidine derivative, namely 3-(2-(4-(hydroxymethyl)-1 H -1,2,3-triazol-1-yl)ethyl)-2-methyl-6,7,8,9-tetrahydropyrido[1,2- a ]pyrimidin-4-one, on the corrosion of mild steel in 1.0 M HCl medium was investigated using the weight loss, the Tafel extrapolation technique and t…
A novel metamaterial, which exhibits a wideband double negative behavior in X-band, is proposed, designed, and investigated in this paper. The metamaterial is composed of modified S-shaped split-ring resonators (S-SRR). The periodic structure is designed and simulated using CST MWs. Next, the experiments are carried o…
C NMR, UV/vis) and structures of 2, 3', 3'', 6, 8 and 9 were determined by X-ray single crystal analyses. It has been unambiguously established that ligands with n ≤ 6 gave heteroleptic binuclear (1-5), while those with n ≥ 7 yielded homoleptic mononuclear (6-9) bis-dipyrrinato complexes. Spectral and structural studi…
Two critical nanoscale design parameters (CNDPs); namely, surface chemistry and interior compositions of poly(amidoamine) (PAMAM) dendrimers were systematically engineered to produce unique hyperpolarizable, electro-optical substrates. These electro-optically active dendritic films were demonstrated to produce high qu…
A polar-to-polar phase transition in a cyanometallate crystal (TA) <sub>2</sub> {(H <sub>3</sub> O)[Co(CN) <sub>6</sub> ]} (TA = thiazolium) triggers multiple switchings of the dielectric constant, second harmonic generation and polarization.
Tensile failure properties of single collagen fibrils were determined using our original tensile test method. Fibrils were directly isolated from the fascicles of mouse tail tendons. Both the ends of each fibril were wound onto the tips of two microneedles several times using micromanipulators. The fibril and tips wer…
In this study, the double perovskite LaBa <sub>0.5</sub> Sr <sub>0.5</sub> Co <sub>2</sub> O <sub>5+δ</sub> (LBSC55) is investigated as a potential cathode for solid oxide fuel cells (SOFCs).
Two-dimensional molybdenum disulfide (MoS 2 ) with few layers, due to their excellent optical and electrical properties, has great potential for applications in electronic and optoelectronic devices. In this work, flower-like MoS 2 nanostructures with ultrathin nanosheets (petals) were successfully deposited onto sili…
In this work, the results of formation of composite membranes with a thickness of about 200 μm with a high electric conduction based on porous silicon and graphene-like films have been presented. A method of CVD film synthesis that makes it possible to form a graphene-like coating on the inner surface of gradient-poro…
We investigated the catalytic properties of Fe1−xNix nanoparticles prepared by a polyol-based method that allowed the precise control of their composition and structure. In the hydrogenation of propyne, the reaction rate decreased with decreasing x, which was in good agreement with the scenario that inactive Fe atoms…
