Modulation of Cerium Carbonate Crystal Growth by Polyvinylpyrrolidone using Density Functional Theory

open access: yesActa Chimica Slovenica, 2022
Cerium carbonate crystal morphology is predicted using density functional theory (DFT) simulations in this paper. In the nucleation phase, the ketone group in polyvinylpyrrolidone (PVP) will preferentially bind to Ce3+ to form complexes and provide ...

Misperception of Body Weight After Childhood Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Misperception of body weight can negatively impact the weight management efforts of childhood cancer survivors (CCSs). Both being overweight or underweight are associated with chronic health conditions commonly observed in CCS; therefore, accurate weight perception is critical for reducing long‐term health risks.

First principles study of metal/Bi2Te3 interfaces: Implications to reduce contact resistance [PDF]

open access: yes, 2009
We investigate the band offsets and stability for Ni/Bi2Te 3 and Co/Bi2Te3 interfaces by first principles calculations. It is found that the surface termination strongly affects the band offsets. Ni and Co are found to form Ohmic contacts to Bi2Te 3. The
