New artificial materials
and their applications are of crucial importance in Nanotechnology. Actually
Liquid Crystals (LC) are seriously promissing materials because of their self
assebled properties. In the scope of this talk, some case studies are discussed
with mainly LC based materials in first three case studies and a Phosphore
based two dimensional material and its application in energy storage is
discussed in the fifth one, all throughout with our experiments. While, the
forth case is the review of the employment of the Spinel Ferrite Magnetic
Nanoparticles in Organic Solar Cell (OSC) Technology, where potential of magnetic nanoparticles (MNPs) discussed to
improve OSC morphology, inhibit recombination, and enhance charge carrier collection.
Thus, incorporation of MNPs led to a
substantial increase in short-circuit current density and fill factor, resulting
in a significant boost in power conversion efficiency.
In regard to our LC
experiments, the first application is devoted for diffraction grating
experiments, which are performed by the usage of fullerene balls, graphene
sheets and some other nanoparticles in the structure of LC molecules so that we
advance the performance of the proposed material, which is an effiecient
candidate for Holographic Storage(In principle 1TByte storage per cubic
centimeter). In the second case study, reorientation of Carbon Nanotubes (CNT)
in LCs are discussed and our experimental outputs, revealing the efficient
reorientation via Electric Fields and Magnetic Fields, are demonstrated. Later
on sandwiched designs are discussed for flexible transistors with some more
feeds to mind for possible future applications and further advances. The last
case study is devoted to the research of an efficient and sustainable electrode
materials for advanced energy storage systems, particularly in lithium-ion
batteries (LIBs). Here, we propose Black phosphorus (BP) as an emerging
promising candidate owing to its unique layered structure and exceptional
electronic and electrochemical properties. An innovative approach for preparing
phosphorene, a two-dimensional (2D) material derived from BP, through a
two-step method involving ball milling and subsequent exfoliation is applied. Whereby, exfoliated phosphorene exhibits
remarkable physicochemical properties, including a large surface area, high
carrier mobility, and excellent electrical conductivity, positioning it as an ideal
candidate for electrode materials in LIBs. Some early results are encouraging to
fully exploit the potential of BP-derived materials in the energy storage
applications.
