Resorcinol/formaldehyde (RF) foam resin is an attractive material as a low-density target in high-power laser–plasma experiments because of its fine network structure, transparency in the visible region, and low-Z element (hydrogen, carbon, and oxygen) composition. In this study, we developed disk-shaped RF foam and deuterated RF foam targets with 40–200 μm thickness and approximately 100 mg/cm3 density having a network structure from 100 nm to a few micrometers cell size. By deuteration, the polymerization rate was drastically slowed down owing to kinetic isotope effects. These targets were used in high-power laser experiments where a megaelectronvolt proton beam was successfully generated.

通过再沉淀法制备了富勒烯C60/酞菁的复合纳米微粒。这种复合纳米微粒由于C60分子和酞菁分子间的π-π相互作用而具有电子给体-受体(donor-acceptor)结构,而且这种微粒的尺寸可通过选择再沉淀过程中使用的溶剂来进行控制。此外,这种微粒与Nafion结合后,表现出去除三甲胺的光催化性能,而且其光催化活性优于C60微粒/Nafion或酞菁微粒/Nafion复合物。该结果表明电子给体-受体结构可通过促进有机半导体的电荷分离来增强光催化的性能,从而揭示了一种新颖的基于电子给体-受体结构的有机光催化剂。
