Poly glycolic acid (PGA) is an aliphatic polyester which chemical structure consists without side chains. Due to the high molecular density, PGA has very high gas barrier property. It can be utilized for many forms of packaging applications which require gas barrier.
Nanofiltration membranes attract attention to take a role of the high performance purification of water. The purification processes with a little energy consumption are enabled by the selection of membrane materials and driving conditions.
A wide variety of biopolymers are utilized in the food industry for rheology control. Fermentation derived biopolymers such as native gellan gum and xanthan gum exhibit an elastic response to a small deformation or force as well as an insensible viscosity under flow, offering innovative opportunities in stabilizing suspensions without negatively impacting the mouth-feel.
Atomic force microscopy is a powerful tool to study materials in a molecular level. However, observations of soft polymeric materials in a high resolution are still challenging. We review recent achievements in observations of polymer chains at a resolution close to, or better than 1 nm by using well-defined two-dimensional films. The observations include the molecular structure of poly(methyl methacrylate) stereocomplex and detailed helical structures of synthetic helical polymers.
All scientific experiences such as the experiments performed last month, the literatures searched this week, and the manuscript submitted today, will navigate initiatives in the future through accidental necessity.
