Precipitation Gravimetry

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Electron Carriers

Electron Carriers

Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Catalysis

Catalysis

The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

SN2 Reaction: Mechanism

S_N2 Reaction: Mechanism

The kinetic studies of SN2 reactions suggest an essential feature of its mechanism: it is a single-step process without intermediates. Here, both the nucleophile and the substrate participate in the rate-determining step.
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...

Rate-Determining Steps

Rate-Determining Steps

Relating Reaction Mechanisms
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

Summary

This summary is machine-generated.

Nickel transfer from fingers to the face can cause facial dermatitis in nickel-allergic individuals. Handling coins showed higher nickel levels on fingers and faces compared to controls, supporting this transfer theory.

Area of Science:

Dermatology
Environmental Health

Background:

Nickel allergy is a common cause of allergic contact dermatitis.
Facial dermatitis can be challenging to manage, with external triggers often implicated.

Purpose of the Study:

To investigate the role of fingers as a pathway for nickel transfer to the face.
To correlate nickel levels on fingers and face with nickel hypersensitivity and facial dermatitis.

Main Methods:

Utilized the adhesive tape stripping method to collect samples from fingers and cheeks of volunteers.
Quantified nickel levels using mass spectrometry.
Compared nickel concentrations between individuals handling coins and a control group.

Main Results:

Nickel was detected on both fingers and cheeks of individuals who handled coins.
Significantly higher nickel levels (14.67–58.64 ppm on fingers, 1.28–8.52 ppm on cheeks) were found in the coin-handling group compared to controls.
Control group exhibited considerably lower nickel levels.

Conclusions:

Fingers serve as a significant source for nickel transfer to the face.
Handling nickel-containing objects like coins can lead to facial nickel exposure.
This transfer mechanism provides a plausible explanation for facial dermatitis in patients with nickel hypersensitivity.
