Atmospheric nucleation is the dominant source of aerosol particles in the global atmosphere
and an important player in aerosol climatic effects. The key steps of this process occur in the …

Inhibition of vascular endothelial growth factor-A (VEGF) signaling is a promising therapeutic
approach that aims to stabilize the progression of solid malignancies by abrogating tumor-…

Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday 1 . Atmospheric observations …

We present laboratory studies and field observations that explore the role of aminium salt
formation in atmospheric nanoparticle growth. These measurements were performed using the …

Fundamental questions remain about the origin of newly formed atmospheric aerosol particles
because data from laboratory measurements have been insufficient to build global models…

Purpose: Vascular endothelial growth factor (VEGF) signaling is key to tumor angiogenesis
and is an important target in the development of anticancer drugs. However, VEGF receptor (…

We present measurements of the distributions of droplet size and charge along with, for
selected droplets, the variation of droplet size and charge with time for electrosprays of methanol…

Measurements of aerosol chemical and hygroscopic properties and cloud condensation
nuclei were carried out as a part of the third Pallas Cloud Experiment. In this study, the aerosol …

… James KA Smith is associate professor of philosophy and director of Seminars in Christian
Scholarship at Calvin College in Grand Rapids, Michigan. Working primarily in the areas of …
