Kuat Rekat Tarik dan Geser Bahan Bonding pada Perekatan Awal Braket dengan Pengetsaan dan Perekatan Ulang Tanpa Pengetsaan

open access: yesJournal of Dentistry Indonesia, 2015
The incidence of loose brackets during orthodontic treatment has reached 5%; therefore, loose brackts should be rebonded. Rebonding without etching might decrease chair time without compromising bond strength.

On the Hydrogen Bond Strength and Vibrational Spectroscopy of Liquid Water

open access: yesScientific Reports, 2018
In the present work, we introduce two new metrics i.e. hydrogen-bond strength and charge-transfer between the donor/acceptor water molecules as a measure of hydrogen-bond rearrangement dynamics. Further, we also employ a simple model based on energy flux
