Characteristics of Silicon Dioxide Particles in PCVD Synthesizing Silica Glass Process

Journal of Nanotechnology, 2016
SiO2 nanoparticles in PCVD process were investigated by SEM, TEM, and optical emission spectra (OES). There are large spherical SiO2 particles with diameter of 50–200 nm and more small particles about 10–50 nm in PCVD process.

“We Cannot Talk as a Family”: Complexities of Survivorship Communication Among Hispanic/Latino Young Adult Survivors of Childhood Cancer, Parents, and Clinicians

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Young adult childhood cancer survivors (YA‐CCS) have an increased risk of treatment‐related health complications throughout their lives. Lifelong survivorship care is recommended, yet many YA‐CCS experience disruptions in care during pediatric‐to‐adult transitions and do not receive recommended survivorship care.
