Mycosynthesized magnetite particles:Comparative physicochemical properties and antifungal activity
(Elsevier, 2026) Prabhugaonkar, Arya; Mordekar, Rajashri Karmali
The study focuses on antifungal applications of Fe3O4 synthesized by Chemical and fungal methods. Fe3O4 is synthesized by conventional hydroxide method and mycosynthesized using fungi G. lucidum and P. rimosus. The Fe3O4 synthesized by all three methods is Pure, crystalline and magnetic. Fe3O4 synthesized by fungal methods show fine crystallite size and agglomeration than the one synthesized by chemical method. There is evidence of phenolic and amino groups which are indicative of phytochemicals in mycosynthesized Fe3O4. All synthesized samples are good antifungal agents against pathogenic fungi C. albicans and A. flavus with sensitivity in the range of 500 to 7.81 μg/mL. Fe3O4 synthesized using P. rimosus (P– Fe3O4) shows better sensitivity (S) at concentrations from 500 to 4.0 μg/ml for pathogens C. albicans and A. flavus in comparison to G- Fe3O4 and C– Fe3O4. The materials show sensitivity superior to some of the reported composites of magnetite with noble metals and Schiff bases like Fe3O4@Ag, Fe3O4@SiO2/Schiff Base/Cu(II)MNPS These potential antifungal agents being magnetic, can be used synergistically with antifungal drugs which will facilitate their movement within the target tissue by means of external magnetic field. This will also minimize the dosage and toxicity of the antifungal drugs.

Gliricidia sepium-derived high surface area meso/micro-porous carbon for enhanced capacitance and adsorption performance
(Elsevier, 2026) Sakli, Firdosh; Mordekar, Rajashri Karmali; Samant, Purnakala V.
Carbon-based materials, due to their unique structural and physicochemical properties, are used in various environmental and energy applications. The present investigation reports a sustainable approach to valorise Gliricidia sepium (GS) into porous carbon with a large surface area. Carbon was synthesized through carbonization and KOH activation, with varying KOH-to-carbon ratios. The influence of the KOH activation ratio showed variation in structural and morphological character in activated carbon, which influenced the electrochemical and dye adsorption performance. Among the samples, GSC5K achieved a specific surface area of 2670 m2 g−1 with a pore volume of 1.33 cm3 g-1, enabling efficient ion transport and adsorption. Further electrochemical studies demonstrated a notable specific capacitance of 329 F g−1 at 5 mV s−1, positioning GSC5K as a strong candidate for supercapacitor application. Additionally, GSC5K demonstrated enhanced methylene blue adsorption (250 mg g−1) achieving complete removal within 120 s under refined kinetic monitoring, surpassing the adsorption capacity of commercial activated carbon. Thus, the work highlights an enhanced GS-derived carbon for sustainable energy storage and wastewater treatment.

Quality of Life and Burden in Caregivers of Patients with OCD: A Scoping Review
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Shirodkar, Ridhima R; Warrier, Manjusha
Aim: This scoping review aimed to synthesize the quality of life (QoL) and perceived burden among caregivers of patients with Obsessive–Compulsive Disorder (OCD). Background: The QoL and burden among caregivers of patients with OCD is an important but under-researched topic, given that OCD can significantly impair the QoL of both patients diagnosed with OCD and their caregivers. Method: A scoping review approach was used to identify articles published in peer-reviewed journals between the years 2010–2024. The search yielded a total of 511 articles from 5 databases, namely, Science Direct, PsycInfo, PubMed, JSTOR, and Google Scholar. Ten articles that fit the inclusion criteria were selected. All the articles followed a quantitative approach; the mean age of caregivers was approximately 48 years, the number of caregivers ranged from 50 to 120, and the majority of the articles had samples with more female caregivers, mostly spouses/parents of the patient. Results: The four themes derived through the synthesis included caregiver support priorities, illness trajectory and caregiver strain, detrimental caregiver response, and socioeconomic disparities and QoL. Conclusion & Implications: Synthesizing the existing literature can guide the development of evidence-based strategies to alleviate the burden among and enhance the QoL of caregivers.

Navigating Growth and Sustainability: Strategy Mapping Across the Life Cycle of a Fishermen’s Cooperative
(Vidarbha Arthashastra Parishad, 2025) Dhaimodka, Sarvesha; Sukthankar, Sitaram V.
This study maps strategies adopted by a fishermen’s marketing cooperative to sustain and grow across its life cycle stages. It employs an exploratory case study aligned with Cook and Burress's (2009) lifecycle framework, using in-depth interviews, documents, observations, and informal discussions as data sources. Findings show that each phase presents distinct challenges that can be addressed through timely, stage-appropriate strategic choices. The study highlights the importance of a robust financial foundation and complementary activities, such as retailing and banking, providing a practical framework for cooperative leaders—especially in developing countries to prevent stagnation and foster long-term success.
