Article Abstract
Electric two-wheelers are gaining popularity due to environmental benefits, extensive operating temperature, and low running costs. However, various environmental factors significantly affect their energy consumption rate and overall performance, with ambient temperature being the critical one. This study investigates the impact of ambient temperature on energy consumption rate and performance of electric two-wheelers by utilizing real-world driving data. An experimental setup consists of drive cycle source, speed control unit, motor control unit, battery pack, and motor with varying ambient temperatures ranging from 15 °C to 40 °C. The experimental setup utilized various sensors to collect parameters such as speed, temperature, current, voltage, state of charge, state of health, and driving range. The result shows that the optimal operating temperature for electric two-wheelers is between 20 °C and 30 °C, where energy efficiency and driving range are maximized. At 15 °C, the driving range decreases to 112.41 km, approximately 2 % lower than at moderate ambient temperature, while at 40 °C, the driving range increases by 2 %, reaching 114.68 km. The study also reveals that an extreme ambient temperature reduces the battery's useable capacity, negatively impacting power output and driving range. Additionally, the battery pack's cell temperature rises by 2.2 °C above the ambient temperature in both low and high conditions.

The incorporation of a glassy material into a self-assembled nanoparticle (NP) film can produce highly loaded nanocomposites. Reduction of the NP diameter can lead to extreme nanoconfinement of the glass, significantly affecting the thermal and physical properties of the nanocomposite material. Here, we investigate the photostability and photodegradation mechanisms of molecular nanocomposite films (MNCFs) produced from the infiltration of indomethacin (IMC) molecules into self-assembled films of silica NPs (11-100 nm in diameter).

Organic-inorganic hybrid ferroelectric compounds of the halobismuthate family have emerged as a focal point of research owing to their reduced toxicity and distinctive optical characteristics. This study presents a novel ammonium hybrid perovskite, [BPMBDMA]·[Bi2Br9], which exhibits both ferro- and piezoelectric properties and crystallizes in the polar noncentrosymmetric 2 space group. The nonlinear optical (NLO) activity of [BPMBDMA]·[Bi2Br9] was corroborated through second harmonic generation measurements evidencing its noncentrosymmetric structure, which was further substantiated by piezoresponse force microscopy analyses.

The cuticle, an extracellular hydrophobic layer impregnated with waxy lipids, serves as the primary interface between plant leaves and their environment and is thus subject to external cues. A previous study on poplar leaves revealed that environmental conditions outdoors promoted the deposition of about 10-fold more cuticular wax compared to the highly artificial climate of a growth chamber. Given that light was the most significant variable distinguishing the two locations, we hypothesized that the quantity of light might serve as a key driver of foliar wax accumulation.

The geographic mosaic of coevolution predicts reciprocal selection, the first step in coevolution, to vary with changing biotic and abiotic environmental conditions. Studying how temperature affects reciprocal selection is essential to connect effects of global warming on the microevolutionary patterns of coevolution to the ecological processes underlying them. In this study, we investigated whether temperature influenced reciprocal selection between a plant (Brassica rapa) and its pollinating butterfly herbivore (Pieris rapae).
