Nonlinear buckling and postbuckling of orthogonal carbon nanotube-reinforced composite (Orthogonal CNTRC) cylindrical shells subjected to axial compression in thermal environments surrounded by elastic foundation are presented in this paper. Two layers of shell are reinforced by carbon nanotube (CNT) in two orthogonal…
A series of cis -platinum(II) acetylide complexes containing two-photon-absorbing chromophores have been synthesized and characterized to explore the effects of stereochemistry on the nonlinear absorption properties. The molecules feature 4-(phenylethynyl)phenylethynylene (PE2), diphenylaminofluorene (DPAF), and benzo…
Abstract The aim of this study was to assess the long‐term impact that the addition of biomass provokes on superheater materials exposed to fireside corrosion environments. Alloys covering a broad range of commercially available materials were investigated. Their corrosion kinetics under different corrosive deposits a…
Two-dimensional electron gas (2DEG) buried in ultrathin barrier AlN/GaN heterostructures is the key to exploit high-speed and high-power devices in the aspect of modern semiconductor electronics. Here, we report Shubnikov-de-Haas oscillations of the 2DEG in an AlN/GaN heterostructure with planar anisotropy along [11-2…
One of the major challenges in modern car body construction is the reduction of component weight while still maintaining passenger safety. In terms of these requirements, the substitution of conventional steel grades by ultra-high strength materials is the most promising approach. Hot stamping of these steels has deve…
A photonic heterostructure (HS) with two integrated periodicities is fabricated by combining the features of a diffraction grating and a colloidal photonic crystal. The top surface of the self-assembled photonic crystal, grown using colloids of 254 nm, is patterned with grating structures in optical disks using soft-i…
Various types of insulation models with time‐invariant parameters are available in the literature. Depending on the aging sensitive performance parameters to be evaluated, different models need to be employed (e.g. XY model for oil and paper‐conductivity, conventional Debye model (CDM) for paper‐moisture and tan δ ).…
The charging current of surface traps in AlGaN/GaN high electron mobility transistors with a slot gate structure was investigated. A slot was formed in the middle of the gate metal via the lift-off process. Even though the slot gate only partially controlled the channel, the transient drain current gradually decreased…
The main goal of the present work was to investigate the damages photoinduced by pterin (Ptr), an endogenous photosensitizer present in human skin under pathological conditions, on a globular protein such as ubiquitin (Ub). Particular attention has been paid on the formation of covalent adducts between Ptr and the pro…
In the quest to understand the dynamics of distributed systems on time-dependent spatial domains, we study experimentally the response to domain deformations by Faraday wave patterns – standing waves formed on the free surface of a liquid layer due to its vertical vibration – chosen as a paradigm owing to their histor…
The aim of this research is to improve the electrical properties of dielectric liquids. An examination of the dielectric properties of mineral oil‐based nanofluids was carried out, using three different nanoparticle types: titanium dioxide, zinc oxide, and barium titanate, each with a mean diameter not exceeding 100 n…
Abstract Anatase TiO 2 has become a material of great interest for photocatalytic production of hydrogen, environmental purification and solar energy conversion. Among the key parameters boosting the photocatalytic efficiency of the anatase nanoparticles, an increased light absorption to expand its optical response to…
Celecoxib (CEL) Nanocrystalline Solid Dispersion (CEL_NCSD) was generated by spray drying CEL, mannitol (MAN) and sodium lauryl sulfate (SLS) from a solvent mixture of methanol, acetone and water. The purpose of the work was to determine the size of CEL nanocrystals, investigate agglomeration and inspect dissolution o…
TiO 2 nanospheres wrapped by graphene‐like g‐C 3 N 4 nanosheets were fabricated through the one‐pot solvothermal process and applied as lubricant additives in paraffin base oil to characterise the tribology performances. Moreover, g‐C 3 N 4 /TiO 2 composites were investigated by different characterisation methods such…
We present electrically detected-magnetic-resonance (EDMR) identification of major and minor interface defects at wet-oxidized 4H-SiC(0001¯)/SiO2 interfaces for C-face 4H-SiC metal-oxide-semiconductor field-effect transistors. The major interface defects are identified as c-axial types of carbon-antisite-carbon-vacanc…
A direct synthesis pathway of tetraethyl orthosilicate from silica and ethanol was recently proposed. Although this pathway has many advantages over the conventional one producing tetraethoxysilane (TEOS) from metallurgical silicon, its potential can be further increased by the effective removal of its byproducts. Thi…
Photosensitizers need to be activated by external light to achieve phototherapy. However, unsatisfactory tissue penetration of light and uncontrollable light intensity limit their application. To overcome the limitations, a novel fluorescent conjugate was developed by conjugating coumarin-functionalized nanosilica wit…
The authors propose an experiment to demonstrate the Schwinger mechanism, namely the production of particle-antiparticle pairs under strong electric fields, for chiral quasiparticles in a Dirac semimetal. The paper shows that this mechanism appears to be related to the quantum conformal anomaly, and the running of the…
In this comprehensive investigation, it is demonstrated how chloride ions may permeate a crack-free oxide scale, thus providing hitherto missing mechanistic insight as to the impacts of KCl(s) or HCl(g) exposures on the high-temperature corrosion of biomass- and waste-fired boilers. Guided by dedicated experimental an…
Superconductivity in materials whose crystal structure lacks inversion symmetry is a prime candidate for unconventional superconductivity. A new noncentrosymmetric compound ${\mathrm{Zr}}_{3}\mathrm{Ir}$ crystallizes in a tetragonal $\ensuremath{\alpha}\ensuremath{-}{\mathrm{V}}_{3}\mathrm{S}$ structure. The magnetiza…
