Diluent effects on combustion characteristics of hydrogen/methane fuel mixtures under colorless distributed combustion regime

W Al-Rikabi, E Yildirim, O Kekul, S Karyeyen Energy Sources, Part A: Recovery, Utilization, and Environmental Effects 48 …, 2026

In this study, the effects of the diluents (N2, CO2, He, and Ar) on a hydrogen/methane flame under colorless distributed combustion conditions were investigated, with a focus on temperature and pollutant emission profiles. The temperature change percentage in the combustor was 51.41% under CO2 dilution, showing that CO2 was the most effective diluent for achieving...

M Ekinci, SO Cirik, E Yildirim, M Turan, M Aydin, E Yigider, A Cangönül Horticulturae 12 (3), 310, 2026

As climate change continues to alter rainfall patterns and precipitation regimes across the globe, waterlogging is emerging as a widespread and pressing issue that threatens agricultural productivity and food security. In this study, we investigated the potential of humic substances to mitigate waterlogging stress in cabbage (Brassica oleracea L.) seedlings. Specifically, humic acid and fulvic...

A Kayabaş Avşar, E Büker, E Yildirim, D Casoni, SCA Cobzac Chemistry & Biodiversity 23 (3), e03371, 2026

This study provides an analysis of the endemic plant Mattiastrum paphlagonicum Bornm.(Synonym Paracaryum paphlagonicum (Bornm.) R.R. Mill), focusing on enzyme activity, secondary metabolite content, antioxidant capacity (DPPH, ABTS, and FRAP), as well as phenolic and flavonoid levels, all within the context of a hydroethanolic extract prepared from M. paphlagonicum and its biodiversity, for the first time. Rosmarinic acid and rutin were identified...

Biostimulants Enhance the Growth and Nutritional Quality of Lettuce (Lactuca sativa L.)

M Turan, M Ekinci, E Yigider, M Aydin, M Akca, S Argin, Nİ Eken Türer, ... Horticulturae 12 (1), 75, 2026

Biostimulants have emerged as effective tools for enhancing both the productivity and quality of crops. In this study, we assessed the impact of the two commercial biostimulant products (Kiana Earth® and Kiana Climate®) on the growth, yield, and quality of lettuce (Lactuca sativa L.). Eight treatments were established, comprising six different biostimulant formulations, a normal...

Foliar Application of Nanoselenium Enhances Drought Tolerance in Brassica oleracea var. italica Through Antioxidant Reinforcement and Pigment Stabilization

SI Vicas, CA Rosan, D Padilla-Contreras, SD Cavalu, R Zsiros, IM Borza, ... Life 16 (1), 70, 2026

Drought stress is one of the major constraints limiting crop productivity, primarily through oxidative damage, pigment degradation, and metabolic imbalance. Nanostructured selenium particles (SeNPs) have recently attracted attention for their potential to enhance plant tolerance to abiotic stress. In this study, green-synthesized SeNPs, with a main hydrodynamic size distribution in the range of 90–100 nm,...

Effects of dopamine on reducing salt stress damage in pepper (Capsicum annuum L.) at morphological, physiological, biochemical, and molecular levels

S Ucar, E Yaprak, M Ekinci, M Yuce, M Aydin, M Turan, E Yigider, G Agar, ... Annals of Applied Biology, 2026

Salt stress is a major environmental challenge that significantly reduces agricultural productivity, particularly in arid and semi‐arid regions. Excessive sodium chloride (NaCl) accumulation in soil negatively affects plant growth, physiological functions, and biological processes. Dopamine, a catecholamine neurotransmitter, has emerged as a potential regulator of plant stress responses. This study aimed to investigate the effects...

Enhanced Salt Stress Tolerance in Maize Using Biostimulant and Biosurfactant Applications

Z Gul, M Ekinci, M Akca, M Turan, E Yigider, M Aydin, NI Eken Türer, ... Agronomy 16 (1), 100, 2025

This research was conducted to investigate effects of biostimulants containing plant growth-promoting rhizobacteria and enriched biosurfactants, which were tested individually and in combination (biostimulant + enriched biosurfactant) on plant growth parameters, physiological and biochemical properties of maize seedlings under different salinity conditions (0, 100, 200 mM NaCl). In the experiment, biostimulant (B: 0.3 g/L), enriched...

Strigolactone mitigates nickel toxicity by regulating nutrient uptake, antioxidant defense, vitamins and phytohormones biosynthesis in pepper seedlings

E Yildirim, M Yuce, E Yaprak, S Ucar, M Aydin, M Turan, TK Ghosh, ... Journal of Hazardous Materials, 140955, 2025

Here, pepper plants were subjected to non-stress control, control with strigolactone (SL), Nickel (Ni)-stress and Ni + SL conditions to investigate the morpho-physiological and biochemical alterations in plant. Excess Ni produced significant negative impacts on plant’s morphology, essential nutrients, and phytohormones content as compared to control plants. However, it caused tremendous increment of hydrogen peroxide...

Systematic Literature Review for Mechanisms and Costs of Plant Adaptation to Biotic and Abiotic Stresses.

MM Abed, M Aydin, E Yiğider, M Ekinci, E Yildirim Phyton (0031-9457) 94 (12), 2025

Plants are continuously exposed to abiotic and biotic stresses that threaten their growth, reproduction, and survival. Adaptation to these stresses requires complex regulatory networks that coordinate physiological, molecular, and ecological responses. However, such adaptation often incurs significant costs, including reduced growth, yield penalties, and altered ecological interactions. This review systematically synthesizes recent advances published between...

Emerging trends in photo-crosslinkable polymeric biomaterials in regenerative medicine

Z Akhmetkarimova, S Mukhlis, E Yildirim, G Zhumanazarova, V Ogay, ... Materials Today Chemistry 50, 103172, 2025

The rapid development in biomedicine presents both challenges and opportunities for macromolecules and polymers development. In this regard, click chemistry emerged as a powerful platform for constructing diverse and innovative materials tailored for biomedical applications. Light (photon)-driven click reactions proceed generally under near-ultraviolet (UV), mid-UV light or visible light are known as photoclick reactions. These...
