Investigation of sintering methodologies and its influence on magnetic and electric properties of NiFe2O4: a comparative study, Kumar, N Pavan, Chary, K Abhishek, Sumana, B, Rao, K Sambasiva, Suresh, M B, Raja, M Manivel, Srinivas, A
Abstract In this work, we use density functional theory calculations with a hybrid exchange–correlation functional and effective core pseudopotentials to determine the geometry of bare and phosphine-protected Au8 nanoclusters and characterize their electronic structure. Au8 clusters were bonded to four and eight PH3 l…
In this study, we prepare series of low-density polyethylene (LDPE)/recycled polyethylene terephthalate (RPET) blends using melt extrusion. The effects of RPET content on the crystallization behavior and thermal conductive properties of the resultant blends were investigated using DSC, XRD, DMTA, TGA, etc. RPET was fo…
The growth of a flat, covering, and single-crystalline IrO 2 (110) film with controlled film thickness on a single-crystalline TiO 2 (110) substrate is reported. The preparation starts with a deposition of metallic Ir at room temperature followed by a post-oxidation step performed in an oxygen atmosphere of 10 –4 mbar…
A new biomimetic stimuli-responsive adaptive elastomeric material, whose mechanical properties are altered by a water treatment is reported in this paper. This material is a calcium sulphate (CaSO 4 ) filled composite with an epoxidized natural rubber (ENR) matrix. By exploiting various phase transformation processes…
Abstract This review focuses on recent advances in the synthesis and characterization of calcium aluminate glasses and the effects of various ion additions/substitutions on the processing and properties of these glasses. Calcium aluminate‐based glasses are of great scientific and technological interest because of thei…
Ultrashort single-walled carbon nanotubes (SWCNTs) that fluoresce brightly in the shortwave infrared could open exciting opportunities in high-resolution bioimaging and sensing. However, this material remains largely unexplored due to the synthetic challenge. Here, we describe a high-yield synthesis of fluorescent ult…
V–W/TiO 2 -based catalysts, which are used for the removal of NO x from the exhaust of diesel engines and stationary sources via selective catalytic reduction with NH 3 (NH 3 -SCR), were studied by operando X-ray absorption spectroscopy (XAS) and emerging photon-in/photon-out techniques. In order to minimize the influ…
MXenes hold immense promise for diverse applications that highly depend on the compositional and structural features of both the carbide frame and interlayer functional groups. Here, we show that electron probes can controllably impart metal atoms in the carbide slabs to the functional group slabs in MXene multilayers…
Quasicrystals are a class of ordered solids made of typical metallic atoms but they do not exhibit the physical properties that usually signal the presence of metallic bonding, and their electrical and thermal transport properties resemble a more semiconductor-like than metallic character. In this paper I first review…
The use of collagen and gelatin in the field of regenerative medicine is widely extended. However, most of the studies in this topic are focused on the scaffolds' properties, but only a few are related to the properties of the raw material used. The raw material analysis not only consists of a study of the composition…
Abstract Chirality or the handedness of objects is of prime importance in life science, biology, chemistry, and physics. It is also a major symmetry ingredient in frustrated magnets revealing spin-spiral ground states. Vector-chiral phases, with the twist (either clock- or counter clock-wise) between neighboring spins…
Precise patterning and localization of functional nanomaterials is the key step for miniaturization and building of optoelectronic devices. Present study utilizes a robust methodology for the multicolor patterning of luminescent Indium Phosphide/Zinc Sulfide Quantum Dot (InP/ZnS QD) film, by taking the advantage of QD…
Fusion is a relatively new concept to produce unique members of the porphyrin family. A representative compound formed by fusion is N-fused porphyrin, which is synthesized from N-confused porphyrin. N-Fused porphyrin has an unusually narrow HOMO–LUMO energy gap and exhibits absorption in the near infrared region up to…
Influence of chemical substitution on broadband dielectric response of barium-lead M-type hexaferrite, Alyabyeva, Liudmila N, Torgashev, Victor I, Zhukova, Elena S, Vinnik, Denis A, Prokhorov, Anatoliy S, Gudkova, Svetlana A, Góngora, David Rivas, Ivek, Tomislav, Tomić, Silvia, Novosel, Nikolina, Starešinić, Damir, Do…
This study elucidates a mechanochemical polymerization reaction towards a hyper-crosslinked polymer as an alternative to conventional solvent-based procedures. The swift and solvent-free Friedel–Crafts alkylation reaction yields a porous polymer with surface areas of up to 1720 m2g−1 and pore volumes of up to 1.55 cm3…
Polymethine bridges in cyanine dyes may be constrained by setting them into edge-fused ring systems, or extended by conjugation with carefully chosen heterocycles. Recent studies have shown that modifications like these can give significantly brighter dyes with red-shifted absorbance and emission maxima.
Due primarily to the inherent brittleness of poly(lactic acid) (PLA), numerous studies have sought to improve the mechanical properties (e.g., fracture toughness) of PLA for a wide range of contemporary applications. In this study, we report a facile method by which to prepare esterified poly[styrene- b -(ethylene- al…
Abstract Graphene nanoribbons are ideal candidates to serve as highly conductive, flexible, and transparent interconnections, or the active channels for nanoelectronics. However, patterning narrow graphene nanoribbons to <100 nm wide usually requires inefficient micro/nano fabrication processes, which are hard to impl…
We investigate the molecular geometry of the carboxyl group of formic acid in acetonitrile and aqueous solutions at room temperature with two-dimensional infrared spectroscopy (2D-IR). We found that the carboxyl group adopts two distinct configurations: a configuration in which the carbonyl group is oriented antiparal…
