Abstract Recent advances in experimental and computational methods are increasing the quantity and complexity of generated data. This massive amount of raw data needs to be stored and interpreted in order to advance the materials science field. Identifying correlations and patterns from large amounts of complex data i…
The possibility of minimizing the operating voltages of the diode structure with a field emission cathode based on an array of carbon nanotubes is investigated. The numerical simulation method was used to perform theoretical calculations that showed the potential for an unlimited reduction in the operating voltage by…
Surface pretreatment plays important role in improvement of corrosion resistance and adhesion of organic coatings. A new generation of metal pretreatments based on nanosize zirconium oxide or ogranosilane film has been investigated recently as an alternative method to phosphatation. In this paper, ZrO2/silane composit…
Treating polyvinyl chloride material with plasma, and the contact angle and shear strength, then study the changes of wettability and surface cohesiveness of the polyvinyl chloride material after modification. Measuring the background mass spectrometry and the mass spectrum of the intermediate product in the treatment…
Abstract In this article, crystallinity and phase dependent insulator-to-metal transition (IMT) of vanadium oxide (VO)-based metal-oxide-semiconductor (MOS) devices is studied at higher measuring temperatures where the sputtered VOs are deposited in different Ar:O 2 ratios at room temparture. The VO phases were identi…
Dental glass fiber is one of dental synthetic fibers that are widely used in dentistry as a dental resin reinforcement, such as in dentin replacement material. The availability of glass fiber is limited in Indonesia because it must be imported and relatively expensive. Bombyx mori silk-fiber is one of the strongest na…
PENGARUH PERISAI RADIASI PADA PENYIMPANAN KERING BAHAN BAKAR NUKLIR BEKAS UNTUK REAKTOR DAYA EKSPERIMENTAL Di masa mendatang, Badan Tenaga Nuklir Nasional (BATAN) berencana membangun Reaktor Daya Eksperimental (RDE) dengan daya termal 10 MW. RDE merupakan merupakan reaktor suhu tinggi dengan bahan bakar berupa pebble…
Hereby, a sonochemical method for synthesis of pure magnetic Fe 3 O 4 nanoparticles (Fe 3 O 4 -NPs) in large scale is being introduced. Synthesis proceeds via simple approach, at room temperature, under sonication, using cheap reagents, green antioxidant-reductant reagent and without using inert gas purge as protectiv…
In considering the future development of organic current injection laser devices, it is indispensable to develop an n-type semiconductor material exhibiting excellent luminescence ability. Therefore, the author focused on bis-styrylbenzene which is an optoelectronically superior skeleton and trifluoromethyl groups whi…
Abstract We report a novel combination of nanomaterial proposed as a peroxidase‐like enzymatic mimic for detection of H 2 O 2 , where CeO 2 nanoparticles dispersed on SBA‐15 through synthesis by the impregnation‐decomposition cycles method (IDC). The system displays a good peroxidase‐like activity and catalyzes to the…
Abstract Preparing counter electrode (CE) with low cost and high catalytic activity is a method for improving the photovoltaic performance of quantum dot-sensitized solar cells (QDSSCs). Here, ZIF-67 thin films are prepared on an Ni sheet and FTO-conducting glass substrate by electrophoretic deposition at different ap…
[Objective] To prepare tetraethylenepentamine functionalized reduced graphene oxide (TEPA-Gn) by a one-step process. [Method] Tetraethylenepentamine (TEPA) was grafted with graphene oxide (GO) under mild condition of 70°C and in the presence of sodium hydroxide which acted as a catalyzer. [Results] The structural anal…
A diamond-like carbon (DLC) film with a nanostructured surface can be produced in a two-step process. At first, a metal-containing DLC film is deposited. Here, the combination of plasma source ion implantation using a hydrocarbon gas and magnetron sputtering of a zinc target was used. Next, the metal particles within…
ABSTRACT A new CoZn nanoferrite and its moderately calcined counterpart were produced by the polyol method aiming to assess their effectiveness for the removal of Cr(VI) species from aqueous solutions. The produced nanoparticles (NPs) were systematically studied by various techniques. X-ray diffraction revealed the fo…
Recently, a novel two-dimensional (2D) metal-free organic material, the C4N3H monolayer, has been proposed and predicted to be a 2D Dirac material with high Fermi velocities. Herein, we investigated its mechanical properties and tensile strain effects on its electronic properties based on first-principles calculations…
Poor dispersion between graphene nanofiller and polymer matrix would limit the development and application of the polymeric composites. In our study, three reduction methods, chemical reduction using hydrazine hydrate (N2H4·H2O), high temperature, and solvothermal methods were used to reduce graphene oxide; then reduc…
