Field emission from flat graphene sheets is a challenge due to fewer emission sites. Here, we have synthesized free-standing vertically oriented few-layer graphene (FLG) films directly on dielectric substrates by hot-filament chemical vapor deposition (HFCVD) without any catalyst or special substrate treatment. The fa…
In this study, continuous microcrystalline diamond layer with grain size of 0.8–2 µm, nanocrystalline diamond layer with grain size less than 100 nm, diamond-like carbon layer with no apparent grains and TiAlN layer with small particles on the top surface are successfully deposited on cemented tungsten carbide-cobalt…
This study focuses on the electrical properties of polycarbonate (PC)/poly(ε‐caprolactone) (PCL)‐multiwall carbon nanotube (MWCNT) nanocomposites. MWCNTs were incorporated into thermoplastic PC matrix by simple melt blending using biodegradable PCL based concentrates with MWCNT loadings (3.5 wt%). Because of the lower…
Commercial α-cellulose was compression-molded to produce 1A dog-bone specimens under various operating conditions without any additive. The resulting agromaterials exhibited a smooth, plastic-like surface, and constituted a suitable target as replacement for plastic materials. Tensile and three-points bending tests we…
The effects of salt, molecular weight and viscosity, and mass ratio on the apparent activation energy of the cross-linking reaction of epoxy resins and protein hydrolysate were studied by nonisothermal differential scanning calorimetry. The Kissinger equation, the model-free isoconversional method, and the autocatalyt…
Diatom‐based assays have been successfully associated worldwide with the tropic status of lakes. Several studies have demonstrated a correlation between epiphytic diatoms and nutrient load in shallow lakes and wetlands. We examine the relative importance of environmental factors in explaining the structure of epiphyti…
Here we report a general methodology to attain novel hierarchical nanostructures using new polymer scaffolds that self-assemble to form cholesteric 1D photonic mesophases existing in conjunction with microphase segregated domains. To achieve this, a series of liquid-crystalline random brush copolymers (LCRBC) consisti…
This article presents the application of waste sanding dusts in order to evaluate its suitability as reinforcement for thermoplastics as an alternative to wood fibers. The effects of sanding dust loading and nanoclay content on the physical and mechanical properties were also studied. Overall trend showed that with ad…
In the present study, a series of large-scale molecular dynamics simulations have been performed to investigate the atomistic scale fracture behaviours along the boundaries of primary twins in Cu with hierarchically nanotwinned structures (HTS), and compare their fracture behaviours with those in monolithic twins. The…
A polymer-stabilised blue-phase liquid crystal display (PSBP-LCD) with double-side in-plane switching (DS-IPS) electrode structure is proposed. This structure shows the transflective characteristics because the bottom electrodes are made by aluminium material. For transflective displays, it exhibits a well-matched vol…
The aim of this study was to better understand the incorporation of rare‐earth elements in glass‐ceramics of nuclear interest. We synthesized glass‐ceramics from glasses in the system SiO 2 – B 2 O 3 – Na 2 O – CaO – Al 2 O 3 – MoO 3 – Gd 2 O 3 by various heat treatments. Gadolinium is used both as a spectroscopic pro…
Surface modification by means of wear protective and antibacterial coatings represents, nowadays, a crucial challenge in the biomaterials field in order to enhance the lifetime of bio-devices. It is possible to tailor the properties of the material by using an appropriate combination of high wear resistance (e.g., nit…
A novel and facile method for water dispersal of hydrophobic iron oxide nanoparticles based on the amphiphilic PAMAM-C12 dendrimer is described. Stable and highly concentrated water dispersions of multifunctional magnetic nanoparticles were obtained with this single-step approach, and showed interesting relaxometric p…
Methane adsorption and dehydrogenation on nanometer-sized Pt clusters, supported by reduced ceria (110), was investigated using density functional theory with Hubbard corrections. Two Pt nanocluster shapes, hemispherical and tetrahedral, are considered. Both stoichiometric and reduced ceria do facilitate methane adsor…
The adsorption and oxidation of hydrogen on Pt film has been studied by means of in situ real-time attenuated total reflection infrared spectroscopy. Strong hydrogen signal was obtained, which is usually very weak or hard to be detected. By applying the curve-fitting analysis to the spectra, it is concluded that three…
In this work, Fe3O4@SiO2 nanoparticles were coated with mesoporous silica shell by S-N+I- pathway by using anionic surfactant (S-) and co-structure directing agent (N+). The role of co-structure directing agent (CSDA) is to assist the electrostatic interaction between negatively charged silica layers and the negativel…
The decomposition and thermal behavior of poly(ethylene terephthalate) (PET)/carbon nanotubes (CNTs) nanocomposites were studied using thermogravimetric (TG) analysis in air atmosphere. A series of PET/single-walled CNTs (SWCNTs) materials of varying nanoparticles concentration were prepared using the in situ polymeri…
Abstract Several biodegradable polymers are used in many products with short life cycles. The performance of a product is mostly conditioned by the materials selection and dimensioning. Strength, maximum strain and toughness will decrease along its degradation, and it should be enough for the predicted use. Biodegrada…
Biological materials in nature serve as a valuable source of inspiration for developing novel synthetic materials with extraordinary properties or functions. Much effort to date has been directed toward fabricating and understanding bio-inspired nanocomposites with internal architectures mimicking those of nacre and c…
1-[4-(Bromomethyl)phenyl]-1,2,2-triphenylethene (2) was synthesized and evaluated for specific fluorescent prestaining of proteins containing cysteine (Cys) in SDS-PAGE. The molecule showed classic aggregation-induced emission (AIE) property in protein labeling and its quantum efficiency was further enhanced upon reac…
