Phlomoides superba (Royle ex Benth.) Kamelin & Makhm. is a critically endangered tuberous herb of the western Himalaya with a highly restricted distribution in India. The present study reassessed its population status and major threats in the Jallow and Khathil Gango localities of Udhampur district, Jammu and Kashmir. A total of approximately 412 individuals were recorded from the two sites. Populations occurring along roadsides, stream margins, and agricultural field boundaries were small and fragmented, whereas a comparatively large and vigorous population was observed in the relatively undisturbed habitat at Khathil Gango. Habitat destruction, agricultural expansion, residential development, and road widening were identified as the major threats. Although local communities are aware of the traditional medicinal and veterinary uses of the species, no active tuber harvesting was reported during the study. The findings highlight the importance of habitat protection, regular population monitoring, community participation, and integrated in situ and ex situ conservation measures for the long-term survival of P. superba.
The family Mutillidae (velvet ants) is a diverse group of aculeate wasps that remains poorly documented in the north-western Himalayan region. Field surveys were conducted from August 2025 to July 2026 in selected urban and peri-urban areas of Jammu District, Jammu & Kashmir. Specimens encountered in the study areas were photographed and identified using external morphological characters and relevant taxonomic literature. The current study documented five taxa of the family Mutillidae from urban and peri-urban areas of Jammu District, comprising Radoszkowskitilla ceylonica, Smicromyrme sp., Nemka sp., and two unidentified black velvet ant taxa, designated as Mutillidae taxa 1 and Mutillidae taxa 2 as a new record from the study area. The study contributes to baseline knowledge of Mutillidae in the region and highlights the importance of systematic surveys for documenting urban insect diversity.
The novelty of the present study lies in the first-time use of lemon leaf extract (LLE) as an effective green corrosion inhibitor for aluminum in 0.2–0.4 M HCl solution. The inhibition performance was evaluated using mass loss (ML), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS), supported by computational approaches such as molecular dynamics (MD) simulations and density functional theory (DFT). The chemical composition of LLE was characterised by Fourier transform infrared spectroscopy (FT-IR). Additionally, scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) and atomic force microscopy (AFM) were utilised to investigate the surface morphology. The impact of varying LLE concentrations on corrosion inhibition in HCl was investigated between 303–333 K, revealing that an optimal concentration of 2.0 g/L LLE demonstrated a high inhibition efficiency of 92.0
Adsorption technology has gained popularity for removing contaminants from waste water during the last few decades. Banana peel is a popular choice as adsorbent due to its availability, cost-effectiveness, non-hazardous, and biodegradation quality. It is an attractive material for generation of emerging biosorbents by various chemical treatment methods. The use of both naturally and chemically activated biomass therefore got attention in the waste water treatment. The collection of data on decontamination of waste water by various adsorbents derived from the agro-waste, banana peel was found to be potential biomaterials in removal of various emerging water pollutants. This review paper analyzes the use of banana peel-based adsorbents for water pollution remediation, focusing on potential removing organic dyes, phenols, heavy metal ions, antibiotics, and pesticides. Future work should consider the use of agro-waste for actual contaminated water in single as well as multi-pollutants; regeneration, reuse, etc. should get importance.
The growing contamination of water resources from dyes due to anthropogenic activities is a wholesome worry. Thus, exploring different materials capable of removing dye from aqueous medium is need of time. Herein, nanoferrites an important class of magnetic material has been synthesized and tested for removal of malachite green (MG) dye from aqueous medium. The present study reports the preparation of a series of Mg‐Mn doped nanoferrites (MMNF) (Mg 0.9 Mn 0.1 Fe 2 O 4 ) by sol‐gel auto combustion technique in different chemical environments of ethylene glycol (EG) and Melamine (Mel). The nanoferrite material with highest MG dye removal efficiency in preliminary test has been chosen for further batch experimentation to check its overall performance. The selected material was characterized by advanced analytical techniques such as FTIR, UV, BET, XRD, FESEM, and VSM to explore its different properties. The dielectric characteristics and magnetic behaviour analysis by VSM confirmed the soft‐magnetic characteristics of the material. Batch optimization study confirms that the 1 g/L of material is enough the eliminate 93% of 20 mg L −1 MG dye in 60 min of time. The mechanistic study along with pseudo‐second order kinetic model and Langmuir isotherm model confirms the involvement of electrostatic force of attraction and weak H‐bond in the chemisorption of MG dye by MMNF material. The easy synthesis protocol with magnetic characteristics and effective MG dye removal efficiency makes MMNF a feasible material for removal of MG dye from water.
