Layered rare earth compounds in the RMn2X2 series (R = rare-earth; X = Ge, Si) are of interest for potential cooling applications at lower temperatures as they enable the structural and magnetic behavior to be controlled via substitution of R, Mn, and X atoms on the 2a, 4d, and 4e sites respectively. We continue investigations of the Pr1−xYxMn2Ge2 magnetic phase diagram as functions of both composition and Mn-Mn spacing using X-ray and neutron diffraction, magnetization and differential scanning calorimetry measurements. Pr1−xYxMn2Ge2 exhibits an extended region of re-entrant ferromagnetism around x ∼ 0.5 with re-entrant ferromagnetism at inline image for Pr0.5Y0.5Mn2Ge2. …

In this study we present the synthesis of a new theranostic system consisting of a core-shell structured nanoceramic-drug conjugate that can potentially combine chemotherapeutic, targeting, diagnostic and radio dose enhancing features in cancer treatment. The conjugate is made of α-Bi2O3 nanoparticles (NPs) which were first coated with (3-aminopropyl)trimethoxysilane (APTMS) to form a core-shell structure and then attached with methotrexate (MTX) through amidation between the amine moieties on the shell and the carboxylic acid groups on MTX. While α-Bi2O3 NPs with high effective atomic number can serve as both contrast agent and radiosensitiser in dose enhancement radiation therapy, MTX as an …

The poor response of dye-sensitized solar cells (DSCs) to red and infrared light is a significant impediment to the realization of higher photocurrents and hence higher efficiencies. Photon up-conversion by way of triplet-triplet annihilation (TTA-UC) is an attractive technique for using these otherwise wasted low energy photons to produce photocurrent, while not interfering with the photoanodic performance in a deleterious manner. Further to this, TTA-UC has a number of features, distinct from other reported photon up-conversion technologies, which renders it particularly suitable for coupling with DSC technology. In this work, a proven high performance TTA-UC system, comprising a palladium porphyrin …
