Effects of chromium/fluorine co

2021/2/23Abstract Li-rich layered oxides are identified as the most promising cathode material for lithium ion batteries due to their high specific capacity and energy density. However, capacity fading, voltage decay and inferior rate capability have restricted its development in industry. Herein, we developed a novel cation/anion (chromium/fluorine) co-doping methods to enhance the

Bands, Bonds, and Doping

Another term frequently used to describe this type of bonding is metallic bonding, because solids with this type of bonding exhibit metallic properties and are therefore categorized as metals. As we shall see later in the tutorial, elements with metallic bonding are very good conductors of electricity, because of the nondirectionality of the orbitals (i.e., electrons can easily move in any

CMRIT ENGINEERING PHYSICS: BONDING IN SOLIDS

An ionic bonding is the attractive force existing between a positive ion and a negative ion when they are brought into close proximity. These ions are formed when the atoms of different elements involved lose or gain electrons in order to stabilize their outer shell electron configurations.

Tuning the Photoluminescence of Graphene Quantum

Combined with the clear fluorine peak at 686 eV, the intense peak at 287.1 eV confirms the existence of C–F covalent bonding in F-GQDs []. Figure 2(d) reveals two kinds of bonding in the F 1s spectra, 685.9 eV owing to the semi-ionic C–F bonding and 688.6 eV is due to a covalent C–F bonding pattern [ 24 ].

Doping (semiconductor)

Doping a semiconductor in a good crystal introduces allowed energy states within the band gap, but very close to the energy band that corresponds to the dopant type.In other words, electron donor impurities create states near the conduction band while electron acceptor impurities create states near

Tuning the electronic transport properties of graphene

2011/9/12We demonstrate the possibility to tune the electronic transport properties of graphene mono-layers and multi-layers by functionalisation with fluorine. For mono-layer samples, with increasing the fluorine content, we observe a transition from electronic transport through Mott variable range hopping (VRH) in two dimensions to Efros-Shklovskii VRH. Multi-layer fluorinated graphene with high

Doping: Connectivity of Semiconductors

Electronic devices and instruments, such as digital alarm clocks, mp3 players, computer processors, and the electronics in cell phones, all take advantage of semiconductor technology. Doping provides a way to modulate the properties of semiconductors that have broad applications in daily life.

Up to now, it was mainly supposed that CaCO 3 has ionic chemical bonding. Our investigation implies that the bonding is partly ionic-covalent with stronger covalent effects in calcite crystal. It is worth mentioning that our results on energy bands composition agree rather well with the experimental photoemission data 21 obtained for CaCO 3 crystals.

These results inspired us to explore a unique way to deliver the ionic nanomaterials by taking advantage of the already present mitochondrial transfer between SCs and cancer cells. In a 2D system we show SCs can deliver mitochondria that are fluorescently labeled by rhodamine 6G and HMT-based ionic nanoparticles into co-cultured HEK293 tumorigenic cells.

Chemical Bonding of Partially Fluorinated Graphene

Understanding the interactions of graphene and chemical additives is crucial to achieve control over chemically modified graphene materials. Here, density functional theory and experiments are used to elucidate the chemical bonding of partially fluorinated graphene.

Boron Doped Carbon Nanotubes are close analogues of carbon nanotubes (MWCNTs), but composed of hexagonal B-N bonding networks. MWCNTs possess purely covalent C-C bonds; by comparison, the B-N bond has partial ionic character due to the differences in electronegativity of boron and nitrogen.
