Full Sequence Bleaching with Dimethyldioxirane [PDF]
, 1995 Research work to date has shown dimethyldioxirane to be a very powerful, yet highly selective oxidant. Dimethyldioxirane bleaching may become more important in the future with legislative restrictions on chlorine based bleaching agents as it contains no ...

Space biomedicine‐oriented bioink and biomimetic blood‒brain barrier
VIEW, EarlyView.Bioinks and bioprinting play a pivotal role in the successful delivery of cell models and the fabrication of tissue models for space biomedicine research. This study investigated the effects of hypergravity and vibration on two‐dimensional adherent cells and three‐dimensional embedded cells and provided methods for storing hybrid bioink and high ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety
High Voltage, EarlyView.ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Effects of Surface Sizing Agents on BOD of Recycled Papers [PDF]
, 1974 Surface sizing agents can be major contributors to a mill\u27s BOD loading. A 2% solids application of polyvinyl alcohol will give little or no BOD as compared to a high BOD resulting from a 8% solids application of anionic and cationic starch.

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems
High Voltage, EarlyView.ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

The Retention of Wet Strength Resins as Determined by the Kjeldahl Method [PDF]
, 1952 True wet strength is not a gauge of water proofness of paper, but is a measure of the residual strength of the paper gauged by the mullen, tear, burst, and fold, after the paper has been completely soaked in water and the resistance to water penetration ...

High Voltage, EarlyView.ABSTRACT The incorporation of nanocellulose‐doped insulating paper into the material composition of a given structure has been demonstrated to enhance the material’s mechanical properties and retard the development of cracks. However, the effects of different length‐to‐diameter ratios of nanocellulose are different.
