Reconstructing the intergalactic UV background with QSO absorption lines

open access: yes, 2011
We present a new approach to constrain the spectral energy distribution of the intergalactic UV background observationally by studying metal absorption systems. We study single-component metal line systems exhibiting various well-measured species.

Ionizing Radiation Carcinogenesis [PDF]

open access: yes, 2012
Human exposure to ionizing radiation is a natural part of life on earth. These exposures occur every day from radiation associated with naturally occurring radionuclides in soil, air, and food, and also from cosmic rays. In addition, many people are exposed to dental and medical diagnostic procedures and therapy involving: x rays, gamma rays, charged ...

Active Thermal Field Integration for Marangoni‐Driven Salt Rejection and Water Collection

open access: yesAdvanced Functional Materials, EarlyView.
A thermal gradient fabric (TGF) evaporator with an auxiliary active thermal field can simultaneously increase evaporation rates and achieve long‐term salt rejection. The auxiliary active thermal field is well integrated with solar energy to construct moderate, extensive, and circulating Marangoni flow for salt rejection.
