The Nucleosome Core Particle

The Nucleosome Core Particle

Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

Oxidation of Alcohols

Oxidation of Alcohols

In this lesson, the oxidation of alcohols is discussed in depth. The various reagents used for oxidation of primary and secondary alcohols are detailed, and their mechanism of action is provided.
The process of oxidation in a chemical reaction is observed in any of the three forms:

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis

Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Protection of Alcohols

Protection of Alcohols

This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Background:

Direct alcohol fuel cells require robust electrocatalysts for efficient energy conversion.
One-dimensional (1D) nanomaterials are promising, but precise surface structure control remains a challenge.

Purpose of the Study:

To design and synthesize novel core@multishell 1D nanowire electrocatalysts with enhanced catalytic properties.
To investigate the structure-property relationships for improved ethanol and methanol oxidation reactions.

Main Methods:

Creative introduction of trimetallic nanoalloy, core@multishell structure, and 1D nanowire morphology.
Synthesis of spiny PtFePd@PtFe/Pt core@multishell 1D NW catalysts.
Composition optimization of Pt5FePd2 1D NWs.

Main Results:

Pt5FePd2 1D NWs exhibited remarkable catalytic activity for ethanol and methanol oxidation.
Mass activities were significantly higher (4.0-9.2-fold) compared to commercial Pt/C and Pd/C catalysts.
The catalysts demonstrated favorable stability after durability tests.

Conclusions:

The novel core@multishell structure, spiny morphology, and synergistic effects contribute to advanced catalytic performance.
This work provides a meaningful guideline for designing high-performance electrocatalysts for fuel cells.
