Osteomyelitis, an infection and inflammation of bone marrow, often progresses to chronic stage because of delay in diagnosis and treatment. Once it becomes chronic, intravenous antibiotics therapy is no longer effective as swollen surrounding tissue interrupts blood flow into the infected tissue. In severe cases, debridement of the necrotic tissue becomes necessary to prevent further infection. In this study, for the first time, we produced three-dimensional (3D) printed antibiotics-loaded biode

An experimental study is performed to investigate the thermal and flow characteristics of subcooled liquid nitrogen in a natural circulation loop. A round tube with uniform diameter is fabricated into a circulation loop and vertically located in a cryostat, where a GM cryocooler is heat sink at the top and an electrical heater is heat source nearly at the bottom. Steady flow of subcooled liquid nitrogen in the loop is successfully obtained by setting the heating power at a given level. Temperatu

We are developing a robotic system for auto‐mounting protein crystals from a sample cassette in liquid nitrogen to a goniometer head. A small industrial six joint axis robot is adopted for this system with a custom built actuator. It will be installed at a wiggler protein crystallography beam‐line in Pohang Accelerator Laboratory. Our design goal is to make the system applied to every type of sample pins such as a screw or magnetic types of pins with 18mm length. The sample cassette is designed
