) by chemical vapor deposition (CVD), to achieve homogeneous growth of carbon nanotubes (CNTs) on the surfaces of carbon fibers. The morphology of CNTs grown on carbon fiber surfaces was observed by a scanning electron microscope and high-resolution transmission electron microscope, which revealed the uniform coverage…
A set of multi-segmented Fe/Cu nanowires were synthesized by a two-step anodization process of aluminum substrates and a pulsed electrodeposition technique using a single bath. While both Fe segment length and diameter were kept constant to (30 ± 7) and (45 ± 5) nm, respectively, Cu length was varied between (15 ± 5)…
To understand the active sites requirements for NO x -SCR by NH 3 and for designing better catalysts, four SnO 2 -based solid solution samples with the SnO 2 lattice doped by metal cations possessing redox ability (Ce 4+ and Cu 2+ ) or acidity (In 3+ and W 6+ ) have been purposely designed. It is revealed that the met…
Silver nanoparticles with unique physicochemical properties and high biocide activity attract great interest in the design and in the manufacture of the new generation materials intended for biomedical technologies. This review aims to provide assessment of the bioactivity and usefulness of Ag-based materials in biome…
Thermoplastic segmented polyurethanes (PUs) can exhibit shape memory behavior, if they feature multiple kinds of physical cross-links that can be dissociated at different temperatures. This is the case if the hydrogen-bonded hard phase is joined with soft segments that can partially crystallize, so that the melting tr…
Calcium oxalate, a mineral of low solubility, is found widely in plants, but its fate in soils has been neglected until recently. This review considers the likely forms and reactions in soils that may be significant in the recycling of both calcium (Ca) and carbon (C). In soils, calcium oxalate is both formed by fungi…
Nanoliposomes are considered to be the most successful nanoparticle drug delivery system, but their fate in vivo has not been fully understood due to lack of reliable bioanalytical methods, which seriously limits the development of liposomal drugs. Hence, an overview of currently used bioanalytical methods is imperati…
Abstract Micro/nanostructured materials and lubricant‐infused surfaces, both inspired from structures found in nature, are ideally suited for developing self‐cleaning and high surface area transducers for biosensing. These two classes of bio‐inspired technologies are integrated to develop lubricant‐infused electrodes…
Abstract (MnFe) 2 (P, Si)‐type compounds are, to date, one of the best candidates for magnetic refrigeration and energy conversion applications due to the combination of giant magnetocaloric effect (MCE), tunable working temperature range and low material cost. The giant MCE in the (Mn, Fe) 2 (P, Si)‐type compounds or…
Abstract The single copper atom doped clusters CuAl 4 O 7–9 − can catalyze CO oxidation by O 2 . The CuAl 4 O 7–9 − clusters are the first group of experimentally identified noble‐metal free single atom catalysts for such a prototypical reaction. The reactions were characterized by mass spectrometry and density functi…
Background: In recent years, the textile fibres and fabrics enriched with multifunctional properties have gained much attention and accepted abundantly. In general, the flame-retardation ability to the textile substrates is endowed with one of the most attentive factors that needed applicability in civilian as well mi…
Polyacrylonitrile (PAN) is one of the materials most often used for carbonization. PAN nanofiber mats, created by electrospinning, are an especially interesting source to gain carbon nanofibers. A well-known problem in this process is fixing the PAN nanofiber mats during the stabilization process which is necessary to…
We investigate the electronic band structure and the proximity exchange effect in bilayer graphene (BLG) on a family of ferromagnetic multilayers Cr 2 X 2 Te 6 , X = Ge, Si, and Sn, with first principles methods. In each case the intrinsic electric field of the heterostructure induces an orbital gap on the order of 10…
The blood-brain barrier (BBB) is a limiting factor in nanoparticle drug delivery to the brain, and various attempts have been made to overcome it for efficient drug delivery. Nowadays, it was considered as further issue for brain-drug delivery that the nanoparticle delivered to brain through the BBB reach cancer cells…
A “pseudo photocatalysis” process, being initiated between plasma and N-type semiconductors in the absence of light, was investigated for NO removal for the first time via dynamic probing of reaction processes by FT-IR spectra. It was demonstrated that N-type semiconductor catalysts could be activated to produce elect…
Summary A novel bio‐based nitrogen‐rich and phosphorus‐rich flame retardant (Phyt/PEI‐TA) was synthesized and characterized by Fourier transform infrared, inductively coupled plasma, and thermogravimetric analysis (TGA). Thermal degradation and flame retardant properties of poly(lactic acid) (PLA) containing 20 wt% Ph…
One of the most attractive applications of carbon nanomaterials is as catalysts, due to their extreme surface-to-volume ratio. The substitution of C with heteroatoms (typically B and N as p- and n-dopants) has been explored to enhance their catalytic activity. Here we show that encapsulation within weakly doping macro…

A wide range of experimental and computational studies on carbon allotropes and composites is covered in this review paper. Specifically, we discuss the strategies for engineering graphene, graphene nanoribbon, graphene n…
A novel Fe 2 O 3 –MnO 2 /TiO 2 catalyst was synthesized using a conventional impregnation method assisted with ethylene glycol and used for NH 3 –SCR. The catalyst exhibited superior low-temperature activity over a broad temperature window (100–325 °C), low apparent activation energy, and excellent sulfur-poisoning re…
Bone mineral crystallinity is an important factor determining bone quality and strength. The gold standard method to quantify crystallinity is X-ray diffraction (XRD), but vibrational spectroscopic methods present powerful alternatives to evaluate a greater variety of sample types. We describe original approaches by w…
