Summary: This study explores various strategies to mitigate Pt degradation in proton exchange membrane by considering Pt ion transport. The results show that promoting the Pt band away from the cathode and lowering the Pt ion diffusivity effectively reduce the loss of electrochemical surface area (ECSA) and improve fuel cell durability. Additionally, an inversive transport of Pt ions from membrane to the cathode was observed during the cathodic sweep. The study also evaluates the limit values of mitigated ECSA loss.

Summary: This paper developed a simulation model to determine the range of an electric vehicle by studying the energy consumption through different driving cycles. It was found that the NEDC and JC08 cycles have similar developed speeds in urban conditions, but due to higher speeds, the NEDC cycle can cover a greater distance in equal time compared to JC08. However, the NEDC cycle has low dynamics, which is not suitable for actual urban operation.

Summary: All plants have electrical excitability, but only few can produce a well-defined action potential (AP). The Venus flytrap Dionaea muscipula is able to generate APs with a high firing frequency and speed, allowing it to catch small animals quickly. The captured prey triggers a certain number of APs, which influences the trapping decisions made by the flytrap. The typical Dionaea AP lasts 1 second and consists of five phases, each controlled by specific ion channels, pumps, and carriers.

Summary: This study investigated the dynamic of chlorophyll fluorescence parameters in young wheat seedlings and found a correlation between effective quantum efficiency of photosystem II and biomass accumulation, as well as changes in photosynthetic activity under short-term heating and drought stress. Additionally, the study revealed a positive correlation between Phi(PSII) dark level in young seedlings and tolerance to short-term stress, and a negative relationship between tolerance and non-photochemical fluorescence quenching level under long-term stress conditions. Overall, the results suggest that chlorophyll fluorescence parameters in young seedlings have the potential to predict biomass accumulation and stress tolerance.

Summary: Salinity is a common factor that limits crop productivity. The negative effects of salt stress on plant processes are caused by osmotic stress and toxic ions. The study investigated how salinity affects photosynthesis, transpiration, water content, and cytosolic pH in tobacco and potato plants. Salinity decreased photosynthesis activity and led to a decrease in water content and transpiration. The cytosolic pH also decreased in tobacco and potato plants. The study analyzed potential mechanisms of the effects of salinity on photosynthesis.

Summary: Parameters of illumination, including spectra, intensity, and photoperiod, have a significant impact on plant cultivation under greenhouse conditions, especially for vegetables like lettuce. This study investigated the influence of photoperiod on lettuce production and photosynthesis parameters. The results showed that increasing the duration of illumination can stimulate dry weight accumulation, which can be achieved by either increasing light period or decreasing light intensity.

Summary: This study investigated the effects of different irradiation modes on the physiological, biochemical, and morphometric parameters of lettuce with red and green leaves. The results showed that the impulse illumination mode was most optimal for biomass accumulation and anthocyanin synthesis in red-leaved lettuce. No significant differences in biomass were observed for green-leaved lettuce under different irradiation modes. Moreover, increased photosynthetic activity was found in both varieties of lettuce with 16 hours of operation of LED irradiators, but it did not affect their final productivity.

Summary: This study investigated the mechanisms of systemic functional responses induced by electrical signals. It was found that chronic beta-irradiation had a positive effect on the morphometric parameters and photosynthetic activity of tobacco plants. Irradiation enhanced the plant's response to electrical signals, resulting in temporary changes in chlorophyll fluorescence parameters and increased amplitude and leaf coverage. Irradiation also enhanced signal-induced cytoplasmic acidification and showed stronger inhibition of stomatal conductance in the plants. The study concluded that the effect of irradiation on the systemic response induced by electrical signals mainly occurs during the transformation stage.

Summary: Electrical signals in plants are generated in response to various stressors and can greatly affect different physiological processes. These signals play a crucial role in integrating plant responses to stress, but they may also cause temporary separation between cells or plant parts. This separation can have adaptive benefits by storing energy compounds, limiting damage propagation, and potentially triggering programmed cell death.

Summary: Salinization is a significant factor that limits agricultural plant productivity. Multispectral imaging and the photochemical reflectance index (PRI) can be used to detect early changes in plants under salinization. In this study, we investigated the sensitivity of modified PRIs to changes in pea plants under salinization treatment. The results showed that long-wavelength PRIs decreased, while short-wavelength PRIs increased under salinization. Long-wavelength PRIs were found to be more sensitive to plant changes and could potentially be used as a universal tool for early detection of stress in plants.

Summary: Photodamage is a key mechanism of photosynthetic disruption in plants under stress. Investigating photodamage is important for both basic and applied research. However, the complex mechanisms of photodamage make it difficult to use experimental methods, so developing mathematical models and conducting model-based analysis can overcome these limitations. In this study, a modified Farquhar-von Caemmerer-Berry model was developed to describe photodamage of photosynthetic electron transport in C-3 plants, using experimental results from pea plants. The model analysis showed that inactivation of linear electron flow and Rubisco can both increase and decrease photodamage. Simulation of photodamage under different temperatures and light intensities revealed multi-phase temperature dependences, with paradoxical increases in thermal tolerance observed under high temperatures. It was also found that changes in temperature optimums of linear electron flow and Rubisco can modify temperature dependences of photosynthetic electron transport under photodamage induction, mainly stimulating its photodamage.

Summary: Salinity has a significant impact on important processes in plants and decreases their yield. This study revealed that lower concentrations of NaCl result in cytosolic acidification in plant cells, while higher concentrations can cause an increase or return to normal levels of cytosolic pH. Additionally, salinity inhibits plant development and affects morphology-related parameters. The relationship between cell length and NaCl concentration is nonlinear.

Summary: Magnetic field oscillations may affect the growth and responses of plants to environmental factors. In this study, it was found that a low-frequency magnetic field can modulate the light-induced electric reactions of wheat. Fluorescent and inhibitory analysis revealed the involvement of calcium ions and plasma membrane H+-ATPase in the development of the reaction, with the magnetic field activating H+-ATPase through increased calcium influx.
