Fluorescence spectroscopy employed to compute the antibacterial potential of pure ZnO and Titania (TiO) loaded ZnO (TiO: 2%, 4%, 6%, and 8%) electrospun nanofibers. The study of electrospun nanofibers followed by their structural, morphological and antibacterial properties has been revealed through fluorescence spectroscopy. X-ray diffraction (XRD) analysis of nanofibers calcinated at 600 °C revealed the presence of polycrystalline wurtzite hexagonal crystallographic planes of ZnO with preferred orientation along (101) direction.

Environmentally hazardous radioactive isotopes of iodine may be released from a nuclear power plant as a by-product of uranium fission. The efficient and safe capture of volatile radioiodine is of great significance in the history of nuclear power plants. Due to its high volatility and carcinogenic characteristics, elimination of iodine gas (I) from air is the need of the hour from an environmental and health point of view.

The removal of toxic dye pigments from the environment is of utmost importance since even trace amounts of these pollutants can lead to harmful impacts on ecosystems. Heterogeneous photocatalysis is a potential technique for eliminating microbiological, inorganic, and organic pollutants from wastewater. Here, we report the band gap alteration of ZnO by making its composites with CuSe to enhance photocatalytic activity.

Removal of methyl iodide (CHI) from the air present within nuclear facilities is a critical issue. In case of any nuclear accident, there is a great need to mitigate the radioactive organic iodide immediately as it accumulates in human bodies, causing severe consequences. Current research focuses on removing organic iodides, for which the surface of activated carbon (AC) was modified by impregnating it with different metals individually, i.

The degradation of organic dye pollutants is a critical environmental issue that has garnered significant attention in recent years. To address this problem, we investigated the potential of CaCrO chromite (CCO) as a photocatalyst for the degradation of cationic and anionic dye solutions under sunlight irradiation. CaCrO was synthesized via a sol-gel auto-combustion route and sintered at 900 °C.

Article Synopsis
  • Drinking fluoride-contaminated water (>1.5 mg/L) in central Pakistan is leading to serious dental and skeletal issues, particularly in teenagers, due to levels around 20 times higher than the World Health Organization's acceptable limit.
  • Researchers tested biochar made from pinecones, modified with iron and aluminum salts, to remove fluoride effectively from contaminated water.
  • The modified biochar achieved an impressive 87.13% fluoride removal even amidst competing ions, suggesting it could be a low-cost solution for defluoridating drinking water.

Cocrystallization is a promising approach to alter physicochemical properties of active pharmaceutical ingredients (hereafter abbreviated as APIs) bearing poor profile. Nowadays pharmaceutical industries are focused on preparing drug-drug cocrystals of APIs that are often prescribed in combination therapies by physicians. Physicians normally prescribe antibiotic with an analgesic/antipyretic drug to combat several ailments in a better and more efficient way.

The study endeavored to analyze the risk perception, sense of place, and disaster preparedness in response to landslide disaster-prone mountain areas of Gilgit-Baltistan, Pakistan. To this end, we surveyed 315 rural residents of two vulnerable landslide districts (Hunza and Nagar) of Gilgit-Baltistan. To explore the relationships between the dimensions of risk perception, sense of place, and disaster preparedness, we used partial least squares (PLS) structural equation modeling (SEM) to test the hypotheses.
