    How Graphene Is Aiding Space Exploration
    Aug 18, 2020 | ACS MATERIAL, LLC

    If humankind is ever going to settle new planets and conduct expansive space exploration, we’re going to need radically new technologies. Graphene is the perfect material to step in and lead the way. Graphene is abundant on our planet and, potentially, others; it’s also lightweight, easy to manipulate, versatile, and super strong. One single atomic layer of graphene is 200 times stronger than steel, better at conducting heat and electricity than any other material, and allows 97% of white light to pass through, making it an ideal material for solar energy. Graphene’s discovery in 2004 …

    Jun 16, 2020 | ACS MATERIAL, LLC

    What’s so revolutionary about graphene, a material composed of 100% carbon? Hasn’t carbon been around quite literally forever? Carbon is one of the basic building blocks of life and is found abundantly in all corners of the world. But in 2004, when two researchers at the University of Manchester exfoliated one layer of carbon atoms from a chunk of ubiquitous soft carbon graphite, everything changed. The result was graphene, a single layer of bonded carbon atoms. It’s the world’s first 2D material; one sheet of graphene is one atom thick. Every single carbon atom in graphene is …

    A Detailed Overview of Graphene Nanoplatelets
    May 18, 2020 | ACS MATERIAL, LLC

    Nanoparticles are microscopic particles that, in at least one dimension, measure less than 100nm. Nanoparticles have captured the attention of researchers and technicians around the world in nearly every field because they represent a bridge between atomic structures and bulk materials. Scientists are discovering that many properties are highly size-dependent; the percentage of atoms on the surface area of a particle has a significant impact on properties and performance. As a result, nanoparticles demonstrate different, sometimes vastly different, properties from their bulk counterparts.

Transferring the material is quite common and can be done in different ways, such as utilizing a thermal release tape and PMMA. This report will explain both techniques and its ease in transferring graphene.

    Upconverting Nanoparticles
    Oct 24, 2017 | ACS MATERIAL LLC

    Upconverting nanoparticles have attracted a large amount of interest due to their ability to partake in bioimaging and therapy applications. Upconversions display anti-Stokes shifts in which the summed, single emitted photon has a higher energy than the incident photons.  While this is an unnatural phenomenon, rare earth metals have been used to assist in upconversions due to its multiple excitation levels. With this ability, these nanoparticles can be used to possibly overcome limitations (as found in quantum dots) when displaying fluorescent properties.  In this article, we will discuss …

    Graphene is defined as a single-atomic-layer, 2-dimensional allotrope of carbon atom.  This material has superlative properties of strength, elasticity, electrical conductivity, and thermal conductivity.  It can potentially provide a higher energy density than that of a common supercapacitor.  There are multiple ways to prepare graphene using one of the top-down or bottom-up categorical methods but the most popular within these categories would be the chemical vapor deposition (CVD) as it can produce high-quality graphene film which can be transferred onto a desired substrate relatively …
