Green synthesis of fluorescent carbon dots embedded in silanized cellulose nanofibers: A ensitive and ustainable platform for uranium detection and remediation.

The rise of uranium ions in groundwater in Northern India has raised serious health concerns, including increased cancer cases. This study introduces a novel solution using a hydrothermal method to synthesize highly fluorescent and stable carbon dots (CDs) from Kalanchoe pinnata. These CDs were embedded in silanized cellulose nanofibers (SCNFs) to create an eco-friendly dual-functional adsorbent and fluorescent probe (SCNFs@CDs) for the remediation of UO ions.

Effect of manganese doping on the hyperthermic profile of ferrite nanoparticles using response surface methodology.

Magnetic hyperthermia-based cancer therapy mediated by magnetic nanomaterials is a promising antitumoral nanotherapy, owning to its power to generate heat under the application of an alternating magnetic field. However, although the ultimate targets of these treatments, the heating potential and its relation with the magnetic behavior of the employed magnetic nanomaterials are rarely studied. Here we provide a bridge between the heating potential and magnetic properties such as anisotropy energy constant and saturation magnetization of the nano-magnets by simultaneous investigation of both hyperthermia and magnetism under a controlled set of variables given by response surface methodology.

KTaO -The New Kid on the Spintronics Block.

Long after the heady days of high-temperature superconductivity, the oxides came back into the limelight in 2004 with the discovery of the 2D electron gas (2DEG) in SrTiO (STO) and several heterostructures based on it. Not only do these materials exhibit interesting physics, but they have also opened up new vistas in oxide electronics and spintronics. However, much of the attention has recently shifted to KTaO (KTO), a material with all the "good" properties of STO (simple cubic structure, high mobility, etc.

Epitaxial Structure of (001)- and (111)-Oriented Perovskite Ferrate Films Grown by Pulsed-Laser Deposition.

The epitaxial structures of SrFeO(2.5) films grown on SrTiO(3) (001) and (111) substrates by PLD are reported. A layer-by-layer growth mode was achieved in the initial stage on both substrates.
