The static and dynamic magnetic properties of cerium (Ce) doped yttrium iron garnet CexY3−xFe5O12 (x=0, 0.05, 0.1, 0.15, 0.2) ferrites (YIG) have been reported in this work. The ferrites were fabricated by the traditional solid-state reaction method. All ferrite samples reveal pure garnet structure identified by x-ray…
One of the major obstacles of the magnetic topological insulators (TIs) impeding their practical use is the low Curie temperature (Tc). Very recently, we have demonstrated the enhancement of the magnetic ordering in Cr-doped Bi2Se3 by means of proximity to the high-Tc ferrimagnetic insulator (FMI) Y3Fe5O12 and found a…
One of the lingering controversies in the field of cardiac regenerative medicine has been around the origin of c-kit+ cardiac stem cells in the heart and their contribution towards cardiac homeostasis. A recent study reports that a subpopulation of c-kit+ cardiac progenitors emerges from the cardiac neural crest (CNC)…
We critically address the problem of predicting the thermal boundary resistance at the interface between two semiconductors by atomistic simulations. After reviewing the available models, lattice dynamics calculations and molecular dynamics simulation protocols, we reformulate this problem in the language of non-equil…
The United Nations Educational, Scientific and Cultural Organization (UNESCO) proclaimed in 2005 that Ugandan barkcloth largely produced from mutuba tree (Ficus natalensis) as a “Masterpiece of the Oral and Intangible Heritage of Humanity.” An exploratory investigation of barkcloth a nonwoven material produced through…
Dolichos kilimandscharicus is a perennial herb. In Zimbabwe the tuber powder is used against various insect pests. Saponins from this plant have molluscicidal and fungicidal properties. The aims of this study were to investigate the antibacterial activity of saponins from the roots of D. kilimandiscarius against S. au…
Leiomyoma is a benign smooth muscle tumor usually encountered in the uterus. Primary pulmonary localization is extremely rare in adults and children. However, it must be included in the differential diagnosis of any nodular lung lesion. Its treatment is surgical, with good long-term results. Here, we report a case of…
Of recently, magnetic nano-ferrites have come forward as excellent catalysts for various organic transformations and mitigation of environmental deterioration. In the present investigation, attempts have been made to beneficially modify nickel ferrite nanoparticles by substituting various transition metal ions in to i…
The last two decades have witnessed tremendous advancements in the area of nanophotonics and plasmonics. Undoubtedly, the introduction of metallic structures has opened a path toward light confinement and manipulation at the subwavelength scalea regime that was previously thought to be out of reach in optics. Of centr…
Spin-capable carbon nanotubes (CNTs) are proposed as a promising material for transparent conductive films (TCFs) to replace indium tin oxide (ITO) in optoelectronic and flexible applications. CNT-TCFs were prepared by a dry-spun method, a straightforward transfer process for fabricating CNT-based films. The effects o…

In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney,…
The paramagnetic metallofullerenes wrapped lanthanide metals have many special properties and potential applications, especially as a single-molecule magnet. Herein, we report a spin probe of nitroxide radical for the magnetic dysprosium metallofullerenes. The nitroxide radical was connected to dysprosium metallofulle…
Based on the well-accepted physical understanding that cleavage fracture of structural steels is preceded by plastic deformation, a critical flaw in the Beremin model and its modifications is proposed, and a new statistical model with the power-law distribution of microcracks is obtained to describe the cumulative pro…

Photoluminescence (PL) excitation spectroscopy is applied to observe the evolution of the luminescence spectra from dopant-diffused crystalline silicon wafers with varying excitation wavelength. Utilizing the micrometer-scale spatial resolution achievable with confocal optics in a micro-photoluminescence spectroscopy…
In this study, AA6066 alloy samples were cryogenically forged after annealing and then subjected to solution and aging treatments. Compared with conventional 6066-T6 alloy samples, the cryoforged samples exhibited a 34% increase in elongation but sacrificed about 8%–12% in ultimate tensile strength (UTS) and yield str…
Thick foils of nanostructured permalloy were electrodeposited by applying a current density of 100 mA cm−2 for 48 hours. The bath contained nickel sulphate, iron sulphate, a complex agent, a grain refiner, a stress reducing agent, a buffer and a wetting agent. The bath pH was 3·8. Different parameters were controlled…
ABSTRACT Core–shell polymer microcapsules are well known for their biomedical applications as drug carriers when they are filled with drugs and gas‐filled microcapsules that can be used as ultrasound contrast agents. The properties of microcapsules are strongly dependent on their size (distribution); therefore, equipm…
A quaternary system composed of surfactant, cosurfactant, oil, and water showing spontaneous motion of the oil-water interface under far-from-equilibrium condition is studied in order to understand nanometer-scale structures and their roles in spontaneous motion. The interfacial motion is characterized by the repetiti…
We previously showed that long-lived nanoemulsions, seeming initially vesicular, might be prepared simply by diluting and cooling (quenching) warm microemulsions with n-hexadecane with precooled water. In this paper, we confirm that these systems are vesicular dispersions when fresh, and they can be made with similar…
