The phrase "a class of interesting" is not correct in standard written English.
It seems to be an incomplete thought and lacks clarity. A more complete phrase would be needed to convey a specific meaning.
Example: "We have identified a class of interesting phenomena in our research."
Alternatives: "a category of intriguing" or "a group of fascinating".
In this perspective, fluoropolymers are a class of interesting materials due to their inertness properties.
A class of interesting quantum states for a harmonic oscillator is superpositions (Schrödinger's cat states) of two DNSs of the same amplitude with opposite phases.
Plants represent a class of interesting source of compounds currently being explored for use in metal corrosion protection in most systems, as possible replacement of toxic synthetic inhibitors.
Following the aforementioned prerequisites, Figure 2 illustrates a class of interesting structures generated through variations on such a single mathematical equation.
Therefore, the Mn-Zn-O ternary systems belong to a class of interesting and useful materials in terms of their electrical and magnetic properties.
Electroactive polymers, based on the concept of linking a redox-active core to a backbone with high electronic conductivity, are a class of interesting materials because of the possibility to independently control different properties like electrochromic contrast, conductivity, charge capacity and redox potential window by the proper choice of the two distinct components employed.
Nonlocal boundary value problems of fractional-order differential equations constitute a class of very interesting and important problems.
Shape memory actuators are a class of very interesting actuators due to the high power to weight ratio, plus the fact that they can work in harsh environments and can be easily constructed.
In the case of the family of the nitro-derivative inhibitors, a class of particularly interesting compounds, a round of optimizations was performed with the synthesis and biological evaluation of a series of derivatives aimed at testing the proposed binding mode and at improving interaction with active site residues.
Since the nonlocal boundary value problems can describe a class of very interesting and important phenomena arising from heat conduction, chemical engineering, underground water flow, thermo-elasticity, and plasma physics, this type of problem has attracted much attention of many researchers (see [2 14] and the references therein).
Each topic introduced in the present paper serves as a representative of a larger class of interesting problems that arise frequently in many applications such as design tasks, functional optimization associated with various variational formulations, or a number of problems linked to image evaluation.
