Oxidation Numbers

Oxidation Numbers

In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Pyruvate Oxidation

Pyruvate Oxidation

After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

Dimensional Analysis

Dimensional Analysis

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Dimensional Analysis

Dimensional Analysis

Dimensional analysis is a valuable technique in fluid mechanics for simplifying complex problems by reducing them into dimensionless groups. These groups capture the essential relationships between the variables involved, allowing researchers and engineers to analyze fluid flow without dealing with each variable individually. This approach reduces the number of independent variables, allowing for easier analysis and better understanding of physical phenomena.
In fluid mechanics, dimensional...

Background:

Developing compact, low-power vacuum ultraviolet (VUV) photodetectors is crucial for deep space exploration to reduce costs and extend mission lifetimes.
Current semiconductor-based VUV photodetectors lack the high external quantum efficiency (EQE) required for sensitive signal detection.

Purpose of the Study:

To discover and characterize a novel material with ultrasensitive photoresponse to VUV light for improved photodetector performance.
To enable the development of integrated VUV devices with high responsivity and low power consumption for space applications.

Main Methods:

Synthesis of two-dimensional (2D) magnesium oxide (MgO) using a conformal anneal method.
Characterization of the photoresponse of 2D MgO to VUV light, including sensitivity and EQE measurements.

Main Results:

Two-dimensional MgO exhibits an ultrasensitive photoresponse to VUV light.
The material can detect extremely weak VUV signals (as low as 0.85 pW) with a high external quantum efficiency (EQE) of 1539%.
The enhanced performance is attributed to high charge-collection efficiency of excited carriers.

Conclusions:

The developed 2D MgO material presents a promising solution for creating high-performance VUV photodetectors.
This advancement can lead to prolonged service times and reduced launch costs for deep space explorers.
The findings offer a new pathway for designing integrated VUV devices with superior responsivity and energy efficiency.
