The smear layer created by scaling and root planing is physiologically eliminated in a biphasic process

Brazilian Oral Research, 2015
Mechanical instrumentation of the root surface causes the formation of a smear layer, which is a physical barrier that can affect periodontal regeneration.

A Randomized Controlled Trial of Standard Versus Intensified Tuberculosis Diagnostics on Treatment Decisions by Physicians in Northern Tanzania. [PDF]

, 2014
Routine tuberculosis culture remains unavailable in many high-burden areas, including Tanzania. This study sought to determine the impact of providing mycobacterial culture results over standard of care [unconcentrated acid-fast (AFB) smears] on ...

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

Advanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.

Efficacy of Ultrasonically Activated 12.5% Ethanolic Extract of Salvadora persica, Smear Clear, 0.2% Chitosan, 10% Citric Acid in Elimination of Intracanal Smear Layer: A Scanning Electron Microscope Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: The chemomechanical preparation technique is gaining significant importance. Sodium Hypochlorite (NaOCl) and Ethylenediaminetetraacetic acid (EDTA) are traditional irrigants used, but various studies have shown their deleterious effects on ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Tuberculosis Transmission by Patients with Smear- Negative Pulmonary Tuberculosis in a Large Cohort in The Netherlands [PDF]

, 2020
Background. Sputum smear microscopy is commonly used for diagnosing tuberculosis (TB). Although patients with sputum smear-negative TB are less infectious than patients with smear-positive TB, they also contribute to TB transmission.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.
