In the present investigation, the cadmium sulphide (CdS) nanoparticles are synthesized in the normal gravity i.e. 1 g (called as control) and in simulated microgravity (called as SMG). The SMG was created by using an instrument called Random Positioning Machine (RPM). Cadmium sulfide nanoparticles were synthesized by…
Adsorption of tetramethyltetrazene on NaAu y surface leads to formation of aromatic compounds constituting thermal ionization mass spectrum, in accordance with the ionization rules of nitrogen-containing molecules established earlier. The suggested mechanism of tetramethyltetrazene adsorption on NaAu y surface is char…
Abstract Efficient targeting to tumor tissues and subsequent rapid drug release in cancer cells remains a major challenge for nanodrug delivery systems. Herein, smart nanodrug particles with reduction‐sensitive and active tumor‐targeting ability are constructed based on the nanoprecipitation of glucosamine‐grafted plu…
Abstract To satisfy increasing stringent application requirements for high power wLEDs, we propose a superficial carbon modification method to enhance thermal stability of red‐emitting CaAlSiN 3 :Eu 2+ phosphor via carbon coating by mechanical mixing and thermal post‐treatment at high temperature under N 2 ‐H 2 atmosp…
The field of material science is continually evolving with first-class discoveries of new nanomaterials. The element carbon is ubiquitous in nature. Due to its valency, it can exist in various forms, also known as allotropes, like diamond, graphite, one-dimensional (1D) carbon nanotube (CNT), carbon fiber (CF) and two…
We theoretically investigated electron energy loss spectroscopy (EELS) of ultraviolet surface plasmon modes in aluminum nanodisks. Using full-wave Maxell electromagnetic simulations, we studied the impact of the diameter on the resonant modes of the nanodisks. We found that the mode behavior can be separately classifi…
Enabled with both magnetic resonance and geometric phase, dielectric nanobrick based metasurfaces have shown their unusual abilities to produce high-definition and high-efficiency holographic images. Herein, we further show that such a metasurface can not only project a holographic image in far field but also record a…
Abstract The effects of neutron irradiation on lithium aluminate ceramics and the transport and incorporation of tritium into surrounding components are primary concerns in the development of materials for use in tritium production. The high specific activity and volatility of the tritium in activated samples greatly…
In this study, Low Density Polyethylene (LDPE) and Thermoplastic Starch (TPS) reinforced with different amounts of Starch Nanocrystals (SNCs) with and without Dicumyl Peroxide (DCP) were blended in an internal mixer. The XRD results showed that crystallinity decreases with increasing SNC content with and without DCP.…
Abstract Boron carbide comprises of polymorphs that differ in crystallographic arrangement and stoichiometry. Consequently, specimens extracted from the same batch can exhibit variability in mechanical properties depending on the constituent mixture of polymorphs. In this work, density functional theory simulations an…
Micro-pillars of solution-treated and aged AZ91 magnesium alloy (Mg-9Al-0.7Zn-0.2Mn) have been used to study the influence of precipitates on plastic deformation mechanisms. The micro-pillars were compressed along [5510¯9] and [011¯0] directions in order to activate basal slip and {011¯2} twinning, respectively. The c…
The high demand for quality in the manufacture of absorbent hygiene products requires the adhesive bonds between layers to be as uniform as possible. An experimental study was conducted on two industrial multihole melt blowing nozzle designs used for hot-melt adhesive applications for hygiene products, in order to stu…
In this paper, the axial buckling of boron nitride nanotubes (BNNTs) is investigated by considering the effects of surface and electric field. To achieve this purpose, the surface elasticity theory is exploited and the results are compared with the molecular dynamic simulation in order to validate the accuracy of the…
Abstract In this study, (1− x )Sr 0.75 Ba 0.25 Nb 2 O 6 ‐ x [0.94Bi 0.5 Na 0.5 TiO 3 ‐0.06BaTiO 3 ] solid solution ceramics were prepared and investigated. The length‐diameter ratio of pillar‐like grain increased with increase in x , reaching maximum value of 10.5 at average length of 1.36 μm and diameter of 0.13 μm f…
Abstract We demonstrate the ability of plasma immersion ion implantation to treat all surfaces of a porous polymer structure designed to act as a bone scaffold. We prove that the internal pore surfaces receive ion bombardment by examining the ultraviolet (UV) absorption spectrum of a thin polymer sheet placed inside p…
Molecular Dynamics (MD) simulations were used to investigate the mechanical response and interfacial mixing of Al/Fe system loaded in uniaxial compression at a constant strain rate of 5 × 107s−1 and five temperatures (150, 300, 500, 700, and 900 K). During the simulations, the temperature was kept below the melting te…
Abstract Although hexagonal boron nitride (BN) nanostructures have recently received significant attention due to their unique physical and chemical properties, their applications have been limited by a lack of processability and poor film quality. In this study, a versatile method to transfer‐print high‐quality BN fi…
Abstract A metamaterial absorber is proposed that functions in the medium‐ (3–5 µm) and long‐wavelength (8–12 µm) infrared (medium‐wavelength infrared, MWIR, and long‐wavelength infrared, LWIR, respectively) regions. The proposed design, which consists of periodic cells, can be tuned to achieve single‐band or dual‐ban…
This review focuses on the description of several examples of supramolecular assemblies of phthalocyanine derivatives differently functionalized and interfaced with diverse kinds of chemical species for photo-induced phenomena applications. In fact, the role of different substituents was investigated in order to tune…
Abstract Micro‐thermoelectric generators (m‐TEGs) are considered one of the potential semi‐permanent power sources for portable self‐powered electronic devices. To supply a sufficient amount of power for applications, the m‐TEG needs high‐performance thermoelectric materials as well as a large temperature difference a…
