Data from: Plant species richness and sunlight exposure increase pollinator attraction to pollinator gardens
<p>Evidence documenting the decline of insect populations is accumulating. Efforts have increased to mitigate pollinator losses by establishing gardens to support pollinator diversity. However, knowledge of the specific garden characteristics, landscape features and environmental factors that affect pollinator diversity and abundance is limited, particularly in biodiverse regions in North America. In order to better understand how garden characteristics affect pollinator attraction, we compared pollinator composition across 16 pollinator gardens in the Appalachian ecoregion in North America. We evaluated the effects of garden characteristics (e.g., plant richness, flower abundance, garden size, proportion of native species), landscape features (land-use type, distance to forest) and environmental factors (sunlight exposure) on pollinator richness, overall visitation rate and visitation rate by defined pollinator groups (i.e., solitary native bees, bumblebees, honeybees, lepidopterans and other insects). Solitary bees (i.e., native bees besides Bombus) were the most frequent visitors (61%). We found differences in pollinator species composition between urban and rural gardens. Moreover, plant richness had a positive effect on pollinator richness and an increase in flower abundance increased pollinator visitation rate. Flower abundance, plant richness and high sunlight exposure increased visitation rate of solitary bees. Visitation rate of solitary bees however, decreased with increasing proportion of native plants. Overall, our results indicate that garden characteristics, landscape and environmental factors all are important mediators of pollinator diversity and abundance. Solitary bees were most affected by garden (i.e., plant richness, number of flowers, proportion of native plants) and environmental factors (i.e., sunlight exposure). However, we also identified differential effects of garden and environmental factors across pollinator groups. We suggest that an integrated management approach that considers multiple garden and environmental characteristics could help improve the effectiveness of pollinator garden as a conservation tool and help preserve this key ecosystem service.</p>
Sunlight-powered self-excited oscillators for sustainable autonomous soft robotics
<p>As soft robotics fast advances, full autonomy becomes highly sought, especially if their motion can be powered by environmental energy and self-regulated. This would present a self-sustained fashion in terms of both energy supply and motion control. Currently, autonomous movement can be realized by leveraging out-of-equilibrium oscillatory motion of stimuli-responsive polymers under a constant light source. It would be more advantageous if environmental energy can be scavenged to power robots. However, generating oscillation becomes challenging under the limited power density of available environmental energy sources. Herein, we develop fully autonomous soft robots with self-sustainability based on self-oscillation. Aided by multiphysics modeling, we have successfully reduced the required input power density to around one-Sun level through a liquid crystal elastomer (LCE)-based bilayer structure. The autonomous motion of the low-intensity LCE/elastomer bilayer oscillator “LiLBot” under low energy supply was achieved by high photothermal conversion, low modulus, and high material responsiveness simultaneously. The LiLBot features tunable peak-to-peak amplitudes from 4 degrees to 72 degrees and frequencies from 0.3 Hertz to 11 Hertz. The oscillation approach offers a general strategy for desgining autonomous, untethered and sustainable small-scale soft robots, such as sailboat, walker, roller, and synchronized flapping wings.</p>

Photocatalytic degradation of methylene blue under natural sunlight using Fe2TiO5 nanoparticles prepared by a modified sol-gel method
<p><span>Iron titanate (Fe<sub>2</sub>TiO<sub>5</sub>) nanoparticles with an orthorhombic structure were successfully synthesized using a modified sol-gel method and calcination at 750 </span><span>°</span><span>C. The as-prepared Fe<sub>2</sub>TiO<sub>5</sub> nanoparticles exhibited a moderate specific surface area. The mesoporous Fe<sub>2</sub>TiO<sub>5</sub> nanoparticles possessed strong absorption in the visible light region and the band gap was estimated to be around 2.16 eV. The photocatalytic activity was evaluated by the degradation of methylene blue under natural sunlight. The effect of parameters such as the amount of catalyst, initial concentration of the dye and pH of the dye solution were investigated on the removal efficiency of methylene blue. Fe<sub>2</sub>TiO<sub>5</sub> showed high degradation efficiency in a strong alkaline medium that can be the result of the facilitated formation of OH radicals due to an increased concentration of hydroxyl ions.</span></p>
