In last many years ago there was a great interest in studying the existence of positive solutions for fractional differential equations. Many authors have considered the existence of positive solutions of non-linear diff...

Aim: The aim of this study is to synthesize and characterize the more efficient photocatalyst [zinc oxide nanoparticles (ZnONPs)] via the addition of dopant lanthanum (La) and pineapple peel extract. Pineapple peel as a ...

The current study was used to achieved the green synthesis of pure with different percentages of zirconium-doped cerium oxide nanoparticles (Zr-doped CeO2 NPs) using an aqueous plant extract of Sanvitalia procumbens. The...

In this analysis, A green synthesis method utilizing a plant extract derived from Rumex nepalensis (spreng) was employed to synthesize silver nanoparticles. The synthesized nanoparticles were thoroughly characterized for...

Using zinc nitrate hexahydrate as the precursor and Rhus vulgaris fruit extract as a natural reducing and capping agent, this study describes the environmentally friendly synthesis of zinc oxide nanoparticles (RV-ZnONPs)...

This study aims to examine urban zoning within a linear city in a Bertrand duopolistic competition framework with price discrimination and linear transportation costs. It analyses the effects of introducing an environm...

Abstract Germination is an effective bioprocessing strategy for enhancing the nutritional quality and functional potential of legumes. This study systematically evaluated the effects of controlled germination on the nutr...

AbstractThis article proposes a deterministic radio propagation model using dyadic Green's function to predict the value of the electric field. Dyadic is offered as an efficient mathematical tool which has symbolic simpl...

The so-called driven Liouville–von Neumann equation is a dynamical formulation to simulate a voltage bias across a molecular system and to model a time-dependent current in a grand-canonical framework. This approach in...

Protected cultivation systems offer opportunities for improving potato productivity but are often constrained by inefficient maize stover utilization and suboptimal fertilization practices. In this study, a 4 × 4 fa...

Vegetable intercropping has advantages over single cultivation in terms of less environmental impact. However, to convince farmers to adopt this production system, it is necessary to prove greater efficiency in the produ...

The present study employed white (W), blue (B: 468 nm), red (R: 629 nm) and green (G: 524 nm) monochromatic LED lights for 26 days, from 11:00 to 18:00 (7 h per day), with a average of photosynthetic photon flux density ...

A green and sustainable approach to the direct synthesis ofthioesters has been developed using Fe3O4 as a low-cost, easilyprepared, reusable and environmentally safe catalyst. The crossdehydrogenative coupling (CDC) of v...

Abstract Background Functional outflow tract obstruction (FOO) remains a challenging disease to manage in male dogs. Cystostomy tubes have been used to relieve urethral obstruction while allowing time to achieve effectiv...

Traditional poppy vinegar is a functional fermented food matrix enriched with diverse biomolecules that may contribute to metabolic health. In this study, the effects of thermosonication on the biomolecular profile, anti...

Ulva prolifera (U. prolifera) green tides have become a recurring ecological issue in the Yellow Sea, posing serious threats to coastal ecosystems and regional economies. Traditional optical satellite index-threshold met...

The Comprehensive Environmental Design and Evaluation System (CEDES) is based on a general taxonomic and conceptual framework that allows it to function both as a building sustainability assessment system and as a flexib...

Abstract Photo-redox catalysis has emerged as a new generation of biochemical protocols in proximity labeling, noninvasive therapy, ultrafast activation. However, the well-developed photocatalysts cannot simultaneously p...

Delhi, one of the fastest-urbanising megacities in the Global South, has undergone severe fragmentation of blue-green spaces (BGS) over three decades, driving deterioration of urban ecosystem health through impervious-su...

The Emissions Trading System (ETS) has been functioning in the European Union since 2005. It is aimed at reducing the greenhouse gas emissions produced within the EU in a cost-effective and economically efficient manner....

This study investigates how education, green technology, and clean energy function as explicit indicators of sustainability and ecological resilience in BRICS economies over the period 1995–2021. Moving beyond income-c...

In this work, we report our efforts to develop a novel inorganic halide perovskite-based bi-functional light-emitting and photo-detecting diode. The bi-functional diode is capable of emitting a uniform green light, with ...

This study investigates how the green economy agenda is operationalised through eco-edu tourism along the Ciliwung River in Kelurahan Cikoko, South Jakarta. Drawing on qualitative case-study evidence, the research docume...
