Entropic stabilization plays a key role in the non-uniform distribution of oxygen ions and vacancy defects in gadolinium-doped ceria.

Gadolinium-doped ceria (GDC) is an important fast oxygen ion conductor. O2--ion hopping in different cation environments of GDC is probed using molecular dynamics (MD). We find that at equilibrium, the O2--ions and vacancy defects arrange themselves around the relatively immobile cations in a way such that pairs of O2--ions and vacancy defect (O2--vac pair) are in greater numbers in some cation environments than others.

The role of a neonatal hypothermia alert device in promoting weight gain in LBW infants.

Background: Neonatal hypothermia is a significant risk factor for preterm and low birth weight (LBW) newborns, especially in India. Kangaroo Mother Care (KMC) is one recommended method of thermal control. A wearable device, TempWatch, has been developed to monitor for and detect hypothermia and to promote KMC for preterm and LBW infants.

Iron stores in low and normal birth weight infants at birth and in early infancy.

Serum ferritin levels of low birth weight (LBW; BW < 2,500 g) and normal birth weight (NBW; BW ≥ 2,500 g) infants were evaluated at birth and at 3 mo using electrochemiluminescence immunoassay. At birth, levels were 318.6 (31.

Vitamin A status of low and normal birth weight infants at birth and in early infancy.

Serum retinol levels of low birth weight (LBW; birth weight < 2500 g) and normal birth weight (NBW; birth weight ≥ 2500 g) infants were evaluated at birth and 3 months using high performance liquid chromatography. At birth, levels were 13.3 ± 8.
