We attempted to perform surface microfabrication of the bioabsorbable material lactic acid–glycolic acid copolymer (LG-80) using a micro-imprint lithography technique with a gas-permeable porous mold at less than 5 °C. As a result, high-resolution

Abstract The shape of pebbles on a curling rink was measured using a replica of the ice surface of the rink to understand the characteristics of pebbles after being in contact with stones. We focused on pebbles with flat tops for which the average sh

In the sport of curling, various mechanisms in curl of rotating stones have been proposed; however, the essential understanding of the mechanism has not been clarified. In this study, we attempted to explain the curl of a rotating stone by focusing o

Refreezing of meltwater in firn is a major component of Greenland ice-sheet's mass budget, but in situ observations are rare. Here, we compare the firn density and total ice layer thickness in the upper 15 m of 19 new and 27 previously published firn

A new method was proposed for replicating snow crystals that uses light-curing resin containing no harmful substances, as the replicating material, and the 3D reproduction of a snow crystal by stereolithography was conducted. It was found that a UV l
