    What is Tin disulfide?

    What is Tin disulfide and how does it work? The inorganic compound Tin desulfide has a chemical composition of SnS2. It is a yellow hexagonal flake containing a CdI2 crystalline structure. It is very insoluble in water. However, it is easily soluble and soluble with aqua regia, hot alkaline solution, as well as sodium sulfide solution. This is often used to make golden paint.
    Tin disulfide dissolves in aqua regia or hot alkali solutions. It is also capable of undergoing coordination reaction with concentrated Hydrochloric Acid. However, it is insoluble and insoluble within dilute Hydrochloric Acid and insoluble in water. It can also react with ammonium-sulfide to disperse.
    How to prepare Tin Disulfide
    You can create Tin disulfide by directly mixing tin, sulfur and iodine. This reaction needs heating.
    Sn + 2 SnS2
    Another option is to pass hydrogen sulfuride into the Tin (IV) salt, or Tin (IV), salt solution, and precipitate it.
    Electrochemical behaviour of multi-walled Carbon Nanotubes confined Tin disulfide used as a Negative Electrode of Lithium Ion Battery
    Multi-walled carbon-confined metal-tin nanostructures were prepared using the direct current arc Plasma method. Brad@ihpa.net was first prepared by heating a methane atmosphere with a precursor. Then, brad@ihpa.net microstructures were created through the sulfurization process. Raman, XRD (XRD) as well as transmission electron microscopy, (TEM), showed that the multi-walled carbon-nanotubes were about 400nm in length, the surface carbon layer had been crystallized and was approximately 10 nm thick. Sn brad@ihpa.net Nanostructures are used as anode material in lithium-ion battery. They show a good electrochemical performance. The first charge-discharge Coulomb efficiency of 71% is achieved, and the capacity maintains 703?mAh?g-1 even after 50 cycles. Brad@ihpa.net Nanostructured Electrodes have high-capacity properties due to the fact that different active materials provide the capacity together and that each material's reaction platform is unique.
    Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
    The simple solvothermal process allowed for the creation of a new composite material consisting of SnS2 (SWCNTs), and single-walled, carbon nanotubes (SWCNTs). After it is applied to the lithium-ion battery's negatively electrode material, it has excellent electrochemical performance. It maintains a specific capacity of 515 mAh/g even at high current density (1 A/g), after 100 cycles. To compare, we used the exact same method to synthesize one SnS2 materials and performed electrochemical tests. Although the SnS2 materials have a relatively high initial specific capability, they are slow to degrade and decay quickly after only 20 cycles. The synergy between SnS2 & SWCNTs is thought to explain the superior performance of this composite material for lithium-ion batteries.

    What is Cementite?

    Or iron caride is an iron-carbon compound, or, more precisely, an intermediate transitional metal carbide having the molecular formula F3C. It weighs 6.67% and 93.3% respectively. It is a gray-white crystal powder with a relative density of 7.694. It is insoluble when dissolved in cold, hot, and dilute acid. But, it is soluble in hot concentrated hydrogen chloric acid to make mixtures with hydrogen, methane and other complex hydrocarbons. Do not react with dry oxygen. Iron oxide and carbon can be formed by oxidizing in moist air. It has an orthorhombic structure. It is a soft and fragile material and, in its natural form, is classified as ceramic. This is why it is an integral part of black metalurgisty.

    What does Fe3C mean?
    Fe3C, also known as iron carbide, is also known cementite.

    How do you make cementite?
    Primary cementite
    When the liquid alloy of iron-carbon alloy (hypereutectic yellow cast iron), is cooled below the liquidus, the cementite precipitates.

    Eutectic cemented cementite:
    The ledeburite structure has a point strip cementite that is uniformly distributed in the austenite matrix. This is known as eutectic or eutectic cemite.

    Preeutectoid phase, cementite:
    Alloys with hypoeutectoid/hypereutectoid compositions are always precipitated with a decrease in temperature. This is the proeutectoid Phase. Because of the differences in forming conditions, proeutectoid morphology can be divided into three types, block, reticulate, and Widmanstatten structures.

    Eutectoid cementite:
    Eutectoid cementite refers to the cementite found in pearlite.

    Secondary cementite
    When iron-carbon alloys are slow cooled, such as hypoeutectic iron, hypoeutectic iron cast iron, hypereutectic iron cast iron), the carbon content in austenite becomes saturated. The cementite will then precipitate along austenite's grain boundary, with a network distribution in microstructure. Secondary cementite is the cementite formed from austenite.

    Tertiary cementedite:
    The equilibrium cooling temperature of industrial pure iron falls below the solid solution line for carbon in iron (FeC equilibrium Diagram PQ line), at which point the solubility in carbon in ferrite reaches saturation. At this point, the temperature drops again and the tertiary cemented from ferrite. Because of its small amount, the Tertiary Cementite is precipitated from the Ferrite grain boundary. It generally spreads intermittently along that boundary.


    It refers only to those that exist outside of the mechanical mixture (structure), such a pearlite (eutectoid) or ledeburite.

    Is Graphite a Nanomaterial?

    Graphite is a nanomaterial

    Graphite is a soft, crystalline form of carbon (C). It occurs naturally in metamorphic rocks. It is a common allotrope of carbon and has properties of a metal and a nonmetal, exhibiting high thermal and electrical conductivity, inertness, and lubricity.

    Synthetic graphite is produced from two raw materials: a carbon carrier, usually coal from crude oil, and pitch as a binder. It is then refined in a complex set of high-temperature processes to obtain desired properties.

    It is also used in batteries and fuel cells, as an electrode for electrochemical cells, in brake linings, and foundry facings. It is a key component in lithium ion batteries.

    In its natural state, graphite is grey to black in color and is opaque. It is lighter than diamond and smooth and slippery to the touch. It has a metallic luster and is highly refractory, chemically inert and heat stable at temperatures of 700 degC and above.

    The atoms of carbon arrange themselves in the hexagonal pattern typically seen in diamond and other crystalline forms. The resulting hexagonal layered lattice makes graphite an excellent conductive material for electricity. Unlike diamond, graphite is a poor insulator.

    As a result, it is very difficult to separate a single carbon atom from its lattice. This limiting property, along with its strength and flexibility, is what has made graphite so useful for so many applications. It is also a very durable material, which is why pencils and erasers are made from it.

    The Naming Method of Graphene

    Graphene Graphene consists primarily of carbon atoms that are tightly packed into a single layer, two-dimensional honeycomb lattice structure. Graphene exhibits excellent optical, mechanical, and electrical properties. This material has great potential for applications in materials science and micro-nano processes, energy, biomedicine and drug delivery. It is expected to be a breakthrough material in the near future.
    To regulate the growth of the graphene industry, it is important to have a better understanding of graphene. China Graphene Standards Committee in 2014 reviewed single-layer graphene and double-layer graphene. There are many concepts like reduced graphene dioxide, functionalized graphene and graphene material.

    The material's electronic energy band structure has reached its 3-dimensional limit when there are 10 graphene layers. Therefore, graphene can only be defined within 10 layers. A single-layer graphene is a two-dimensional material made of carbon atoms that are arranged closely in a hexagonal honeycomb structure.

    Two-layer graphenereferss to two layers carbon atoms that are frequently and closely packed into a benzene ring structural (that's, a hexagonal honeycomb construction) and are made up of various stacking methods (including AB, AA, and AA' stacking). Dimensional carbon materials.

    The few-layer grapheneis a 2-dimensional carbon that is composed of 3-10 layers each of carbon atoms. It can be stacked in different ways (including ABC stacking or ABA stacking) and has a benzene ring structure. Material.

    Single-layer Grapheneoxide - A two-dimensional carbon material that has oxygen-containing functional chains attached to the surface or boundary of a one-layer graphene. Grapheneoxide is a carbon material that has oxygen-containing functional links attached to the surface and boundary at least one graphene carbon atom layer. Grapheneoxide also includes the previously mentioned single-layer graphene.

    Single layer reduced graphene oxygen refers to two-dimensional carbon materials obtained by deoxidizing single-layer graphene dioxide by incomplete removal (groups), of oxygen-containing functional units (groups), by chemical, electrochemical, heat or other treatment methods.

    A two-dimensional carbon substance called reduced graphene oxide is created by deoxidizing or reducing the oxygen-containing functional group (groups) of grapheneoxide by chemical, electrochemical or heat treatment. One-layer reduced grapheneoxide is included in the reduction of graphene.

    Functionalized graphene is a kind of graphene that contains heteroatoms/molecules (such as hydrogen, fluorine, oxygen-containing groups and other surface modification to form bonds, nitrogen, boron and other elements substitution doping, heteroatom/molecule intercalation) Etc.) Two-dimensional carbon material. Functionalized graphene can be either the grapheneoxid described above or reduced grapheneoxid.

    This definition includes single-layer graphene as well as double-layer and few-layer versions of graphene. Both can be called graphene material.

    How amazing is graphene?

    What's graphene Graphene can be described as a new material that is composed of a single layer made up carbon atoms, which are packed tightly together to form a hexagonal honeycomb network. Graphene is an allotrope of carbon and a two-dimensional material.



    Graphene only has 0.142 nanometers molecular bond length and 0.335 micrometers crystal plane spacing. It has four atoms of size, making it much smaller than a bacteria.
    Graphene has been the thinnest known compound. It is one atom in thickness. It is also one atom thick.

    Humans and graphene
    Since 1948, graphene was found in nature. It was hard to separate graphene form the monolayer structure at the time. The graphene was all clumped together.
    Graphene, therefore, was considered non-existent for a very long time.
    Scientists Konstantin Voselov (University of Manchester) discovered how to isolate graphene in 2004. The scientists discovered that graphite sheets made from highly-oriented, pyrolytic graphite could be easily separated by attaching them to special tape and then tearing it apart.
    This can be repeated over and over, resulting in thinner sheets. Eventually, graphene is a special type of carbon atoms. Andrei Geim, Konstantin Novoselov received the Nobel Prize for Graphene Discovery.

    Graphene The king material --
    When graphene became known, it changed the face of scientific research all over the globe. One gram graphene will cover the area of a standard football field, as it is the thinnest known material.
    Graphene is also very good at electrical and thermal properties. Pure monolayer graphene, which is defect-free, has a high thermal conductivity at 5300W/Mk, the highest known carbon material.
    Graphene is also very good at conducting electricity. Graphene, which has a carrier mobility value of 15,000m2/(Vs at room temperatures), is 10 times more than silicon, the most widely used material.
    The arrangement of carbon atoms inside graphene is like barbed wire. This arrangement gives graphene unique flexibility. It makes it even more difficult. The graphene's unique flexibility is due to the honeycomb and barbed wire structures created by carbon atoms. Each carbon atom is also perpendicular the orbital, which allows for large bonds to penetrate atoms.

    Graphene applications
    The discovery graphene has opened scientists' eyes to the possibility of movement and action of particles. It has also made our lives more interesting.

    These new energy batteries represent the first steps towards graphene tech. The lithium battery is currently the most common type of battery. While the lithium battery has the capacity to store a lot of electric power for us, its drawback is that it wears too quickly and can be damaged by repeated charging and discharges.
    The graphene material can greatly increase the charging efficiency and capacity of batteries. Additionally, it plays a significant role in prolonging battery life. A graphene tinoxid layer will be used as the anode for a lithium-ion battery. The battery will last longer once it is charged.
    Graphene is a good choice for batteries that last longer and have a higher capacity.




    Because graphene has soft properties, it could be used to create flexible material. The flexible display is one of the most iconic examples.
    The flexible transparent displays produced by the South Korean Institute were made using layers of graphene, fiberglass polyester sheets and other materials. While the project is still in the development phase and has not yet been launched on the market, the project staff believes that flexible transparent displays made of graphene could one day replace "bricks", mobile phones. The phones can be folded up like silly putty.

    Graphene is also used to protect our environment, especially in desalination.
    The channel is just 0.9 nanometers wide when water interacts with graphene. Molecules smaller in size can pass through the channel without difficulty, but larger molecules will get stuck. Graphene can be used to remove large molecules of salt from seawater.

    Graphene's unique properties and excellent properties have led to many achievements in many scientific fields.
