Induced-fit Model

Induced-fit Model

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Induced Electric Dipoles

Induced Electric Dipoles

A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

Induced Electric Fields

Induced Electric Fields

The fact that emfs are induced in circuits implies that work is being done on the conduction electrons in the wires. What can possibly be the source of this work? We know that it’s neither a battery nor a magnetic field, as a battery does not have to be present in a circuit where current is induced, and magnetic fields never do any work on moving charges. The source of the work is in fact an electric field that is induced in the wires. For example, if a stationary conductor is placed in a...

Spontaneous and Induced Mutations

Spontaneous and Induced Mutations

Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).

Background:

Face-centered cubic (fcc) metals are conjectured to form glassy states via deformation.
Nanoscale impact forces induce melting, hindering observation of fcc metal amorphisation.
Previous studies faced challenges in observing amorphisation due to deformation-induced melting.

Purpose of the Study:

To investigate the possibility of inducing amorphisation in pure-element fcc metals at ultra-high strain rates.
To explore the effects of sonication treatment on silver nanowires.
To understand the relationship between nanowire diameter and ductility under extreme deformation.

Main Methods:

Sonication treatment of silver (Ag) nanowires to induce ultra-high strain rates.
Analysis of deformation modes and amorphisation in bent areas of Ag nanowires.
Characterization of the stability and reactivity of sonication-prepared amorphous Ag.

Main Results:

Confirmed amorphisation in Ag nanowires induced by high strain rates generated via sonication.
Observed a diameter-dependent increase in ductility of Ag nanowires due to deformation mode mismatch.
Sonication-prepared amorphous Ag exhibited stability at room temperature and high reactivity.

Conclusions:

Verified the occurrence of high strain rate induced amorphisation in pure fcc metals.
Sonication provides a powerful method for mechanical studies on metal nanomaterials under extreme conditions.
Amorphous Ag demonstrates potential for further material science applications due to its reactivity and stability.
