It is essential to control the size and morphology of nanoparticles strictly in nanomedicine. Protein cages offer significant potential for templated synthesis of inorganic nanoparticles. In this study, we successfully synthesized ultrasmall copper sulfide (CuS) nanoparticles inside the cavity of ferritin (Fn) nanocag…
Among the many novel photocatalytic systems developed in very recent years, plasmonic photocatalytic composites possess great potential for use in applications and are one of the most intensively investigated photocatalytic systems owing to their high solar energy utilization efficiency. In these composites, the plasm…
Interactions between particles in quantum many-body systems can lead to collective behavior described by hydrodynamics. One such system is the electron-hole plasma in graphene near the charge-neutrality point, which can form a strongly coupled Dirac fluid. This charge-neutral plasma of quasi-relativistic fermions is e…
Two-dimensional (2D) transition-metal dichalcogenide (TMD) nanosheets have emerged as a fascinating new class of materials for catalysis. These nanosheets are active for several important catalysis reactions including hydrogen evolution from water. The rich chemistry of TMDs combined with numerous strategies that allo…
Advances in wireless technologies, low-power electronics, the internet of things, and in the domain of connected health are driving innovations in wearable medical devices at a tremendous pace. Wearable sensor systems composed of flexible and stretchable materials have the potential to better interface to the human sk…
A better understanding of turbulent unsteady flows in gas turbine systems is a necessary step toward a breakthrough in compressor applications for hybrid fuel cell gas turbine (FC-GT) systems. In this study, compressor stall/surge analysis for a 220 kW hybrid solid oxide FC-GT system is performed for the two different…
By means of a perturbative scheme, we determine analytically the capillary energy of a spheroidal colloid floating on a deformed fluid interface in terms of the local curvature tensor of the background deformation. We validate our results, that hold for small ellipticity of the particle and small deformations of the s…
Abstract Preferential growth of anatase crystallites along different directions is known to deeply affect their photocatalytic properties, especially with respect to the exposure of the reactive {001} facets. Its extent can be easily quantified through simple geometric calculations, on the basis of crystal sizes extra…
ABSTRACT The ring‐opening polymerization of ɛ‐caprolactone and morpholine mixture was carried out at 160°C for 24 h under nitrogen atmosphere at two different experimental conditions, mercaptoaceticacid (MAA) and Ag‐MAA initiator variation. The resultants were characterized by Fourier transform infrared spectroscopy,…
This paper analyzes the output characteristics of a Galfenol magnetostrictive displacement sensor based on the Wiedemann effect, the Jiles-Atherton model, and the piezomagnetic effect. The sensor which is subjected to simultaneously circumferential excitation magnetic field, bias magnetic field, and stress will induce…
The transition-metal dichalcogenides have attracted a lot of attention as a possible stepping-stone toward atomically thin and flexible field-effect transistors. One key parameter to describe the charge transport is the time between two successive scattering events---the transport scattering time. In a recent report,…
Polymer brushes have a large potential for controlling properties such as surface lubrication or wetting through facile functionalization. Polymer chemistry, chain density, and length impact on the wetting properties of brushes. This study explores the use of diblock copolymer brushes with different block length and s…
In this work, the dynamics of electronic energy transfer (EET) in bichromophoric donor-acceptor systems, obtained by functionalizing a calix[4]arene scaffold with two dyes, was experimentally and theoretically characterized. The investigated compounds are highly versatile, due to the possibility of linking the dye mol…
A first-principles-based effective Hamiltonian approach is used to predict the existence of a highly tunable piezocaloric effect in antiferroelectric ${\mathrm{PbZrO}}_{3}$. The high tunability originates from a strong dependence of both the magnitude and sign of the piezocaloric temperature change on the initial temp…
Abstract Gases dissolved in solvents are usually low in amount but introduce many impurities to certain systems, thus creating disadvantages or advantages which have so far been seldom reported. Evidence of the effects of dissolved gases as impurities on crystallization is provided here. Four types of gases were used.…
We have studied structure and ionic conductivity of La2−xErxMo2O9 (0.05 ≤ x ≤ 0.25). The phase transition observed in La2Mo2O9 is suppressed in Er substituted samples. Cubic β phase in these samples is confirmed from Rietveld refinement at room temperature. The densification of the samples and grain–grain connectivity…
In this work, an experimental approach toward reaching new insights into the mechanism of superconductivity in the iron-based compounds is presented.

In this paper, spherical core@shell (multi-Fe3O4@C) magnetic beads (DMB ~ 100 nm), composed of several single cores of magnetite nanoparticles (MNPs) (Dsingle-core ~ 15 nm) surrounded by a wide carbon shell (δ ~ 20 nm), have been synthesized by a solvothermal procedure in organic solvent that provides good control ove…
The structural evolution and electronic properties of VnC2(-/0) and VnC4(-/0) (n = 1-6) clusters were investigated using photoelectron spectroscopy and density functional theory calculations. The adiabatic and vertical detachment energies of VnC2(-) and VnC4(-) (n = 1-6) clusters were obtained from their photoelectron…
Nanoparticles are environmental contaminants of emerging concern. Exposure to engineered nanoparticles has been shown to have detrimental effects on aquatic organisms. The authors synthesized gold nanoparticles (18.1 ± 3.5 nm) and tested their effects on time to and weight at metamorphosis in wood frog (Lithobates syl…
