Uptake of liquid from wet surfaces by the hairy proboscis

Post Image The tip region of the butterfly Asian comma proboscis was observed, especially two microstructures; the intake slits through which liquid passes into the proboscis and the brush-like sensilla styloconica. During liquid feeding, the sensilla sty...   내용 보기

Liquid-feeding strategy of a butterfly

Post Image  A butterfly drinks liquid food through a long coiled proboscis with a pressure gradient induced by a cibarial pump. However, the long and coiled proboscis make it difficult to position the proboscis tip at the liquid target. In addition, the...   내용 보기

Active ion-mediated sap flow regulation in plants

Post Image The ion-responsiveness of water transport was investigated to understand the mechanism of active water flow regulation in plants. Different ion types significantly affected water transport in xylem conduits. Sap flow rate decreased with an increas...   내용 보기

Two-photon imaging of intracellular chloroplast movements

Post Image \\Intracellular 3D movements of chloroplasts in intact plant leaves were monitored during dark to light transitions by a TPM system. All chloroplasts did not exhibit the same motion in response to irradiation variation. Spatial heterogeneity in ch...   내용 보기

Real-time imaging of pulvinus bending in Mimosa pudica

Post Image Structural characteristics and seismonastic reactions of M. pudica were experimentally investigated using advanced bio-imaging techniques. The results show that the key factors for the flexible movements by the pulvinus are the following: bendable...   내용 보기

Gold nanoparticles as tracer of plants’ sap flow

Post Image In order to use gold nanoparticle(AuNP) with synchrotron X-ray imaging as a tool for visualize hydraulics in xylem vessel, interaction with the vascular network is verified. Effects of AuNP supply on the water refilling function of  monocot ...   내용 보기

Journey of water in pine cones

Post Image Pine cones have structural advantages that could influence the efficient motion of pine cones. Raindrops fall along the outer scales to the three layers (bract scales, fibers and innermost lignified structure) of inner pine cones. However, not all...   내용 보기

Basic physics of transpiration at plant leaves

Post Image Plant leaves have porous structures to pull water from root to the tip of leaves, and they finally release water to the air. The morphological structure of plant leaves has been optimized to efficiently transport water. Inspired by the morpho...   내용 보기

Effective mass transport through porous materials

Post Image Mass transport in porous materials attracts large attention in many engineering applications. Plant leaves, which work as natural hydraulic pumps for water uptake, have evolved to have the morphological structure for fast water transport of leaf ...   내용 보기
