Polarizing ³He by Spin Exchange with Potassium [PDF]

open access: yes, 2004
We present experimental studies on the spin-exchange optical pumping of ³He using alkali metal potassium vapor. High ³He polarizations are achieved using lower laser power than traditional rubidium-³He pumping studies.

Demineralization adjacent to orthodontic brackets with fluoride releasing and conventional bonding agents

open access: yesIndian Journal of Dental Research, 2016
Background: Enamel demineralization is an event which is always an integral part of fixed orthodontic treatment due to which fluoride releasing bonding agents are considered to be the most effective but have lower bond strength. Thus, this in vitro study
