Metallic syringe versus electronically assisted injection system: a comparative clinical study in children.

European journal of paediatric dentistry, 2019
Local anaesthesia injection necessary for pain control in paediatric dentistry may itself be painful sometimes, partly because of the pressure felt during injection; electronically assisted injection systems were developed to address this problem.Study design: The present study is a clinical study in children that compared two types of devices for ...

Automatic In-Syringe Dispersive Microsolid Phase Extraction Using Magnetic Metal–Organic Frameworks

Analytical Chemistry, 2015
A novel automatic strategy for the use of micro- and nanomaterials as sorbents for dispersive microsolid phase extraction (D-μ-SPE) based on the lab-in-syringe concept is reported. Using the developed technique, the implementation of magnetic metal-organic framework (MOF) materials for automatic solid-phase extraction has been achieved for the first ...

Molecular design of a “molecular syringe” mimic for metal cations using a 1,3‐alternate calix[4]arene cavity

Journal of Computational Chemistry, 2010
AbstractThe chemically switchable actions well imitate the function of a “molecular syringe,” has been studied in theory using the 1,3‐alternate calix [4]arene bearing a nitrogen‐containing crown cap at one side and a bis(ethoxyethoxy) group at another side by the π‐basic calixtube as a pipette and the crown ring as a rubber cap.

Development of a syringe membrane-based microextraction method based on metal–organic framework mixed-matrix membranes for preconcentration/extraction of polycyclic aromatic hydrocarbons in tea infusion

Food Chemistry, 2021
Inevitably, the residues of polycyclic aromatic hydrocarbons (PAHs) in tea leaves will be transferred to hot tea infusion, constituting a certain drinking risk; consequently, it is imperative to develop rapid, sensitive, and robust approaches for their trace-level detection.

Generalized Synthesis of Metal Phosphide Nanorods via Thermal Decomposition of Continuously Delivered Metal−Phosphine Complexes Using a Syringe Pump

Journal of the American Chemical Society, 2005
We synthesized uniform-sized nanorods of transition metal phosphides from the thermal decomposition of continuously delivered metal-phosphine complexes using a syringe pump. MnP nanorods with dimensions of 8 nm x 16 nm and 6 nm x 22 nm sized were synthesized by the thermal decomposition of Mn-TOP complex, which was prepared from the reaction of Mn(2 ...

Metal-ligand complex formation between ferrous or ferric ion with syringic acid and their anti-oxidant and anti-microbial activities: DFT and molecular docking approach

Journal of Molecular Liquids, 2021
Abstract Syringic acid is a natural product or phytochemical and has significant properties in different areas like medicinal chemistry, pulp industries and many others. Synergic acid comes under the polyphenols and also known as flavonoinds. It is reported that metal complexes of syringic acid have better biological applications than of the syringic

The Formation of Syringe Acid by the Thermal Degradation of Malvidine-3-Glucoside in the Presence of Catalytic Metals

Revista de Chimie, 2008
Malvidine-3-glucoside degrades in the presence of oxygen, temperature and catalytic metals, as iron, so inducing the colour depreciation of vegetal nutrients like the red wines. In this study is presented the degradation of this anthocyan of a majority of grapes and red wines, as well as the formation kinetics of degradation compounds like the ...
