Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

Chemical Agents for Microbial Control

Chemical Agents for Microbial Control

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

π Electron Effects on Chemical Shift: Overview

π Electron Effects on Chemical Shift: Overview

An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0, resulting in...

Protecting Groups for Aldehydes and Ketones: Introduction

Protecting Groups for Aldehydes and Ketones: Introduction

Protecting groups are compounds that can bind to a specific functional group in the presence of other functional groups to protect them from undesired chemical reactions. These compounds can selectively bind to particular functional groups and advance chemoselective reactions in polyfunctional systems (Figure 1). After the functional group has served its purpose, it is removed by reacting it with specific compounds.

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...

Area of Science:

Materials Science
Surface Chemistry
Fluid Dynamics

Background:

Superomniphobic surfaces repel most liquids, exhibiting high contact angles and low hysteresis.
Existing superomniphobic surfaces are often limited in their effectiveness against non-Newtonian fluids.

Purpose of the Study:

To create surfaces demonstrating superomniphobicity with a broad spectrum of Newtonian and non-Newtonian liquids.
To develop effective chemical shields against diverse liquid types.

Main Methods:

Fabrication of surfaces with hierarchical, re-entrant textures.
Testing liquid repellency using various Newtonian and non-Newtonian fluids, including acids, bases, solvents, and polymer solutions.

Main Results:

The developed surfaces achieved superomniphobicity (>150° contact angle, low hysteresis) with a wide range of liquids.
Demonstrated repellency against Newtonian liquids (acids, bases, solvents) and non-Newtonian liquids (viscoelastic polymer solutions).
Liquids easily rolled off and bounced, indicating minimal solid-liquid adhesion.

Conclusions:

The hierarchical re-entrant textured surfaces effectively reduce solid-liquid contact area.
These surfaces provide robust chemical shielding capabilities against a vast array of organic and inorganic liquids, regardless of their rheological properties.
