However, letters may express a particular opinion rather than a balanced interpretation. Authors of papers commented on are invited to reply, but neither the journal nor peer reviewers should be a…
ZeTe${}_{3}$ belongs to the ample class of chainlike chalcogenide charge-density-wave (CDW) materials. Its peculiarity consists in the formation of the CDW condensate at ${T}_{\mathrm{CDW}}$ along the crystallographic directions perpendicular to the $b$-axis, Zr-Zr chains. Ni and Cu intercalation of ZrTe${}_{3}$ leads…
The Er 3+ concentration dependencies of upconversion luminescence in oxy‐fluoride glass and glass‐ceramics containing PbF 2 nanocrystals were investigated. Strong red emission from the 4 F 9/2 → 4 I 15/2 transition was observed with the addition of ~0.8 mol% Er 3+ ions, whereas ~10 mol% of Er 3+ is required to achieve…
In the fabrication of metal oxide films by the solution process, it is very important to know the state of a gel. In this report, the type of for indium–tin oxide (ITO) gel was determined according to the cohesive energy for agglutinating a gel. We developed the new method of determining a gel’s state to elucidate the…
Electrochemistry represents a dynamic eld with many applications in today’s industrial economy. Electrochemical energy systems are devices that directly convert chemical energy into electrical energy. Fuel cells like batteries or galvanic cells are the most important examples of electrochemical systems. The understand…
Chopped jute fiber-epoxy composites with varying fiber length (2-12 mm) and mass fraction (0.05-0.35) had been prepared by a heat press unit. The cross-linked product was characterized in terms of specific gravity, thermal conductivity, tensile strength, Young modulus and elongation at break. The transverse thermal co…
The present work includes the development of composites in nano based, reinforced with natural fibers. The fibers to be studied come from mechanical extraction from banana. The process, in general, consists of mechanical extraction. Further, the fibers are cut, classified in the adequate mesh and later on undergoes a…
The distribution of Ni 2+ ions in NiO ‐doped 10 YSZ powder is examined with Superconducting Quantum Interference Device magnetometry, a technique that is able to distinguish between randomly distributed Ni 2+ ions in solid solution and ordered Ni 2+ ions within NiO with high precision. Very high purity powders contain…
The average mean‐square radii of gyration for the products of the linear polymerization, the star‐shaped polymerization, and the hyperbranched polymerization of AB 2 ‐type monomer in the absence or presence of a multifunctional core initiator are investigated using the Dobson‐Gordon's method. The dependence relationsh…
Rivers, streams and associated habitats have been sampled for diatoms in the relatively understudied Congo and Zambezi sister basins. The primary purpose of the sampling effort was to collect samples for biological monitoring purposes and the establishment of a diatom-based monitoring programme. However, a large numbe…
Fabrication and controlled localization of BN nanosheets assemblies were performed in polymer-based nanocomposite films under application of DC electric field switching. The localization of BN nanosheets with linearly assembled structure were modulated by applying a Si-mold electrode with micro-dimensional protrusions…
Fragilaria atomus was described from a brackish water lagoon in southern Finland and has subsequently been reported from several localities worldwide. However, due to its small size, it can be easily mistaken with other small, morphologically similar araphid diatoms. To clarify the morphological, metric and structural…
Abstract A novel α‐zirconium phosphate/polyaniline (α‐ZrP/PANI) hybrid film used as K + ion sensor was fabricated on carbon paper by electrochemical method. Mechanisms of film formation and detection of K + ions were also proposed. The exfoliated α‐ZrP was mixed with PANI and deposited on carbon paper. The resultant α…
We report the synthesis and characterization of new Ca(II) and Mg(II) complexes of the type [Ph―PPP]MR (M = Ca, R = N(SiMe 3 ) 2 ( 1 ); M = Mg, R = n Bu ( 2 )) where Ph―PPP − is a tridentate monoanionic ligand (Ph―PPP―H = bis(2‐diphenylphosphinophenyl)phosphine). Reaction of the opportune metal precursor (Ca[N(SiMe 3…
The research of new reliable materials and tailored conservation strategies to preserve metallic artefacts is the aim of this work. Diamond‐like carbon (DLC) thin films, deposited by plasma‐enhanced chemical vapour deposition (PECVD), could be considered as innovative, safe and reliable materials for the long‐term con…
The aim of this study was to investigate the suitability of a novel electrospun polyurethane nanofibre material for water-treatment purposes. Bacterial removal efficiency was tested in the laboratory by filtering artificial water spiked with Escherichia coli through a 0.25 µm nanofibre membrane. The results were compa…
Abstract The biomineralization process produces materials with exceptional microscopic, morphologic, and mechanical qualities, which are finely tuned for specific functionality. This control of the properties is obtained through interactions with bioorganic and inorganic molecules that regulate the formation and/or be…
Fullerene (C(60)), with its unique physical properties and nanometer size, has been mass-produced for many applications in recent decades. The increased likelihood of direct release into the environment has raised interest in understanding both the environmental fate and corresponding biological effects of fullerenes…
Purification of raw single-walled carbon nanotube (SWCNT) material remains an important challenge in nanotube research and applications. We describe here a simple but effective purification method that uses permanent magnets to remove many nanotube aggregates, as well as residual metallic catalyst, from aqueous suspen…
The effective atomic number and effective electron density in amino acids are of significant interest due to their use in various applications. The energy absorption buildup factors, exposure buildup factors, effective atomic numbers, and electron densities of essential amino acids such as Leucine (C6H13NO2), Lysine (…
