Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its releases. This study aims to prove the difference and interaction between immersion time...

Mini screw orthodontics merupakan alat yang digunakan dalam perawatan ortodonsia untuk kasus yang membutuhkan absolute anchorage. Mini screw yang tersedia terbuat dari logam nikel titanium atau stainless steel yang pada...

Fe-doped TiO2 (2, 5, 10, 15 and 20% wt. of Fe) photocatalysts have been synthesized by sol-gel method using titanium aquacomplex precursor. The structure and morphology have been characterized by XRD, BET, SEM, and EDS a...

In this review, we describe the investigation of a ruthenium [Ru(II)] complex-based, AC voltage-driven, electrochemiluminescent (ECL) device first. The ECL turn-on response time and intensity were dramatically improved b...

ABSTRACT Background Skin cancer is one of the most prevalent malignancies worldwide, characterized by the abnormal growth of skin cells and significant clinical challenges. Conventional treatments—including surgery, ch...

Thermolytic decomposition in a chloride-acid medium of a titanium aquacomplex precursor solution [Ti(OH2)6]3+•3Cl¯ as a result of its boiling at a temperature of (110-114) 0С is accompanied by precursor hydrolysis a...

Abstract This study investigates the surface morphology, microhardness, and electrochemical corrosion behavior of Ti-Mn alloys reinforced with hydroxyapatite (HA) at 5, 10, and 15 wt% concentrations, fabricated via spark...

In this work TiO2 modified with nitrogen was synthesized by sol-gel method from the hydrolysis of titanium isopropoxide with urea solution in different concentrations so that the theoretical N/Ti molar ratio was equal to...

This paper presents results of an investigation of the features of phase and structure formation of a ternary compound during thermal sintering use of compacted TiH2-Al-C powder blends. The thermal sintering was carried ...

This paper highlights the relationship between changes in structural and morphological features, electronic structure and exanging of time mechanical treatment at microbraker (MBT). Scaning electron microscopy revealed a...

Background/Aim: The aim of this study is to examine with finite element analysis the distal bar extension, the bar substructure material type and the amount of bar substructure-abutment mismatch, and the stress caused by...

The braking system is a critical safety component in land vehicles, relying on efficient deceleration during operation. Among its elements, the brake disc plays a central role in dissipating the heat generated by frictio...

Microwave ignition (MWI) technology enables synchronized large-area multi-point ignition, multi-pulse operation, higher combustion temperature and efficiency, and dynamic thrust modulation through microwave field adjustm...

The aim of this study was to evaluate sunscreens by Dispersive X-ray Fluorescence (EDXRF) and UV-VIS spectrophotometry, to quantify the sun protection factor (SPF) of the physical filter (micro-fine titanium dioxide) a...
