Square atomic configurations of two-dimensional gold and platinum are designed on the basis of density functional theory calculations. Calculations reveal that Au 9 and Pt 9 clusters form energetically stable perfect square structures. Combining and alternating two Au 9 and two Pt 9 allows for the formation of infinit…
ABSTRACT Binary doped polypyrrole (PPy) encapsulated Titania (TiO 2 ) nanoparticles were prepared by oxidative polymerization using FeCl 3 as oxidant in presence of camphorsulfonic acid (CSA) as surfactant. Both FeCl 3 (oxidant) and camphorsulfonic acid (surfactant) also act as dopant and hence thus prepared polypyrro…
Tritium production is of critical importance to prospective DT fusion power plants. Lithium ceramic and beryllium based solid-type breeder blankets are an option for supplying the tritium required to sustain the DT plasma. This research investigates the time-varying tritium production in solid breeder blankets with di…
Designing versatile 3D interfaces that can precisely represent a biological environment is a prerequisite for the creation of artificial tissue structures. To this end, electrospun fibrous sponges, precisely mimicking an extracellular matrix and providing highly porous interfaces, have capabilities that can function a…
Bombyx mori silk fibroin fibers were grafted with methacrylamide (MAA) and characterized by Raman and infrared (IR) vibrational spectroscopy before and after hydrolysis in NaOH 5% to elucidate the possible interactions between the two components and the stability of the fibers toward alkaline hydrolysis. Upon grafting…
We identify features in the angle-resolved photoemission spectra (ARPES) arising from the periodic pattern characteristic for graphene heterostructure with hexagonal boron nitride $(h\mathrm{BN})$. For this, we model ARPES spectra and intensity maps for five microscopic models used previously to describe moir\'e super…
Controllable, spatially inhomogeneous distributions of CdSe nanocrystals smaller than the exciton Bohr radius are grown in a glass matrix under combined action of sample heating (below the transformation temperature) and focused high-repetition femtosecond (fs) laser beam. Selective quantum dot precipitation is eviden…
Gapped iron-core reactors can obtain larger inductance, but they make larger vibration and noise than other kinds of reactors. On vibration dampers, many researchers kept their eyes on vibration isolation structures or vibration isolation materials. However, they did not compute reactor core vibration under fundamenta…
Development of natural polymer biobased materials that are light responsive is very useful for industrial production and our lives for a sustainable world. In this work, on the basis of the strong hydrogen bonding interaction between cellulose chains and conjugated dye molecules, fluorescent cellulose biobased plastic…
A broad and expanding range of materials can be produced by atomic layer deposition at relatively low temperatures, including both oxides and metals. For many applications of interest, however, it is desirable to grow more tailored and complex materials such as semiconductors with a certain doping, mixed oxides, and m…
Intercalation and de-intercalation of lithium into graphene layers is a well-established phenomenon in Li-ion battery technology. Here we show how this phenomenon can be exploited to destabilize, and alter the hydrogen sorption behaviour of Li-based metal hydrides (LiBH 4 and LiAlH 4 ), thereby achieving lower hydroge…
Although discotic liquid crystals are attractive functional materials, their use in electronic devices is often restricted by high melting and clearing points. Among the promising candidates for applications are [15]crown-5 ether-based liquid crystals with peripheral n-alkoxy side chains, which, however, still have me…
Two glasses of the compositions 2 BaO - TiO2 - 2.75 GeO2 and 2 BaO - TiO2 -3.67 GeO2 (also known as BTG55) are annealed at temperatures from 680 to 970 °C to induce surface crystallization. The resulting samples are analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) including electron backscatt…
The intrinsic atomic mechanisms responsible for electronic doping of epitaxial graphene Moirés on transition metal surfaces is still an open issue. To better understand this process we have carried out a first-principles full characterization of the most representative Moiré superstructures observed on the Gr/Pt(111)…
Many industries require irreversibly responsive materials for use as sensors or detectors of environmental exposure. We describe the synthesis and fabrication of a nontoxic surface coating that reports oxygen exposure of the substrate material through irreversible formation of colored spots. The coating consists of a…
Nanometer-sized Cu-enriched solute clusters containing Mn, Ni, and Si atoms are considered as the primary embrittling feature in reactor pressure vessel steels. In order to understand the effects of solute atoms Mn, Ni, and Si on hardening and cluster formation, reactor pressure vessel model alloys FeCu, FeCuSi, FeCuN…
BACKGROUND: Engineered magnetic nanoparticles (MNPs) possess unique properties and hold great potential in biomedicine and clinical applications. With their magnetic properties and their ability to work at cellular and molecular level, MNP have been applied both in-vitro and in-vivo in targeted drug delivery and imagi…
Plasmon-resonant nanostars (NSts) have recently found applications in biophotonics due to their unique optical and chemical characteristics, showing comparable or superior properties than other anisotropic plasmon-resonant nanoparticles. In this paper, we synthesized gold NSts by the seed-mediated surfactant-free meth…
Incineration is considered to be an effective disposal method for municipal solid wastes (MSW), which is attracting increasing attention due to its great performance in waste reduction. However, one big problem for incineration process is the release of a number of harmful pollutants. Nitrogen oxide (NO x ) is one of…
The glass-forming region in the K2O–MnO–P2O5 ternary system was determined and the amorphous nature of the synthesized material was confirmed by X-ray diffraction. Glasses with composition (50-x)K2O-xMnO-50P2O5 (0 ≤ x ≤ 40 mol%) have been studied. Their physical, thermal and spectroscopic properties such as density, m…
