EVALUATING OF THE EFFECTIVE USAGE OF THE REMOVABLE ORTHODONTIC APPLIANCE WITH A MOVABLE RAMP IN THE TREATMENT OF MESIAL OCCLUSION ACCORDING TO THE ANTHROPOMETRICAL RESEARCH IN MIXED OCCLUSION

Український стоматологічний альманах, 2018
Introduction. In mixed occlusion all methods are based on the existence of sizes relationships patterns of teeth on the one side and the length of the dental arch and jaws apical base on the other.

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

Advanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Arch length changes from 6 weeks to 45 years.

The Angle orthodontist, 1998
The purpose of this study was to evaluate, on a longitudinal basis, changes in maxillary and mandibular arch length over a 45-year period. Subjects were drawn from two pools of normal individuals. Twenty-eight male and 33 female infants were evaluated longitudinally at 6 weeks, 1 year, and 2 years (before the eruption of the deciduous dentition ...

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Arch dimensional changes following orthodontic treatment with extraction of four ‎first premolars

Journal of Oral Health and Oral Epidemiology, 2016
BACKGROUND AND AIM: Tooth extraction as a part of orthodontic treatment plan to create space for leveling and aligning teeth or causing tooth movement leads to changes in arch width and length. The outcome of these changes is important for the clinicians

Wafer‐Scale 2D High‐Entropy Transition Metal Dichalcogenide Thin‐Film Catalysts for Efficient and Durable Photoelectrochemical Hydrogen Production

Advanced Materials, EarlyView.
A wafer‐scale 2D high‐entropy (MoWTaNbRu)S2 thin‐film catalyst with a distorted 1T phase integrated onto p‐Si photocathode is designed for highly efficient and durable photoelectrochemical hydrogen evolution reaction. The high‐entropy effect in layered transition metal dichalcogenides optimizes hydrogen adsorption energetics, accelerates photogenerated
