Methylammonium tin triiodide (MASnI3) films were grown through Sequential Physical Vapour Deposition (SPVD) without breaking the vacuum and optimized by varying MAI thickness and annealing time while keeping SnI2 thickness ...
Nuclear waste storage materials are inevitable in nuclear industry for preventing the release of radioactive waste
products. Glassy carbon has been considered being beneficial to be used in the dry cask needed for nuclear ...

With the advent of novel polymers, organic solar cell (OSC) research has evolved significantly over the
past decade. The molecular engineering of terpolymers has allowed for simple morphological control in
binary devices ...

A one-step solvothermal approach was used to integrate nitrogen-doped reduced graphene oxide into
vanadium dioxide (VO2) to prepare a V@XN-G (where X = 24, 48 and 96 and is the mass of urea as the
nitrogen (N) source) ...

The past decade has seen significant advances in wide-field cm-wave very long baseline interferometry (VLBI), which is timely given the wide-area, synoptic survey-driven strategy of major facilities across the electromagnetic ...
The MIGHTEE survey utilizes the South African MeerKAT radio telescope to observe four extragalactic deep fields, with the aim of advancing our understanding of the formation and evolution of galaxies across cosmic time. ...
Cold gas evolution ties the formation of dark matter haloes to the star formation history of the universe. A primary component of cold gas, neutral atomic hydrogen (HI), can be traced by its 21-cm emission line. However, ...
The Square Kilometre Array mid-frequency array will enable high-redshift detections of neutral hydrogen ( H I ) emission in galaxies, providing important constraints on the evolution of cold gas in galaxies over cosmic ...
Activated carbon (AC) and hexagonal boron nitride (hBN) electrodes were successfully synthesized from Eucalyptus grandis tree bark and a mixture of boric acid and urea in the ratio of 2:3, respectively. The optimal composite ...

Much can be learned about molecular aggregates by modeling their fluorescence-type spectra. In this study, we systematically describe the accuracy of various methods for simulating fluorescence-type linear spectra in a ...
The present study was carried out to investigate the thin film properties of poly (3-hexylthiophene) (P3HT) coupled with graphene oxide (GO) using different spectroscopic techniques. The X-ray diffraction spectrum of GO/P3HT ...
This review explores the field of X-shaped radio galaxies (XRGs), a distinctive
subset of winged radio sources that are identified by two pairs of jetted
lobes which aligned by a significant angle, resulting in an ...

The study investigated the migration behaviour of Sr implanted into SiC in the presence of helium (He). Sr ions
were implanted into polycrystalline SiC samples (Sr-SiC) at room temperature (RT), and co-implanted with ...
