  Cobalt iron oxide nanoparticles , the chemical formula of which is CoFe 2 0 4 , is a nanoparticle material composed of iron and cobalt elements. It has a high specific surface area and good magnetic properties, and is often used in catalysis, batteries, storage media and other fields. And because magnetic nanoferrite particles have biosafety properties, they have important applications in biomedical fields such as magnetic resonance imaging, targeted drugs, cell separation and magnetic hyperthermia, and have become one of the current hot spots in nanomagnetic material research. There are two methods for preparing cobalt iron oxide nanoparticles, physical method and chemical method. Physical methods have major limitations. For example, the requirements for equipment are high, and the product is relatively easy to be oxidized. The properties of the product are not perfect, such as uneven particle distribution and low purity. Therefore, physical methods are generally not used. There...

  Vacuum filtration is an integral part of various industries and scientific fields, including biological laboratories and pharmaceutical cleanup procedures. A   vacuum filtration system   is fundamentally a setup where a vacuum is used to expedite filtration processes. Standard filtration relies on gravity for fluid to ooze through a filter or sieve, a slow and arduous operation. In contrast, the vacuum filtration system uses atmospheric pressure to propel the liquid into a container below the filter, expediting the process considerably. The function of this system is to separate solids from a liquid sample. The most common use being the separation of a precipitate (solid) from a solution (liquid). When suction is applied to the flask (usually via a vacuum pump or aspirator), the reduced pressure in the flask leads to a difference between atmospheric pressure and the pressure inside the flask. This differential pressure accelerates the passage of the liquid portion of th...

Carbon foam, also known as reticulated vitreous carbon (RVC) foam, is a stiff, porous structure formed from a web of carbon atoms. It has attracted increasing attention from academic communities and industry because of its unique 3D porous structure and excellent performance, such as low density with high mechanical strength, high electrical conductivity, tailorable thermal conductivities, high adsorption, electromagnetic shielding, ablation resistance, and large surface area. Carbon foam is an enabling technology for a host of next-generation material systems and components. It can be used as the core material in a structural composite that makes ships more fireproof, as a firewall in airplanes and as energy absorbing structural components in automobiles. The foam material performs well in a marine environment. Basic Parameters Pore size:  0.01-6mm Density:  0.2-1.0g/cm 3 Porosity:  30-80% Compressive strength:  8-12MPa Compressive modulus:  300-620MPa Tensile...

In a broad sense, essential oils are defined as a general term for volatile substances obtained by processing and extraction from plants or animals. However, essential oils in daily use usually refer to aromatic substances obtained from botanical sources by distillation, cold pressing, solvent extraction, or maceration. Essential oils are obtained from various parts of plants, i.e., roots, leaves, seeds, bark, fruits, flowers, stems, etc. They are formed in fixed cells, most often, grouped in channels or in secretory pockets and they are then transported to the different parts of the plant during its growth. Essential oils have important biological properties such as antioxidant, antiviral, antibacterial and insecticidal. Due to these unique properties, they have applications in various fields. Today, essential oil has made an important contribution to the continuous development of the pharmaceutical, beverage, food industry, cosmetics, and perfume industries. Methods of extracting es...

Piperidine alkaloids are widespread among the Apiaceae, Solanaceae, Chenopodiaceae, Fabaceae, Crassulaceae, Lycopodiaceae, and Asteraceae. They are organic compounds containing saturated heterocyclic amine ring, i.e piperidine nucleus – a six membered ring consists of five methylene bridge (-CH 2 -) and one amine (-NH 2 -) bridge. Most of the alkaloids containing the piperidine rings, including pelletierine ( Punica granatum ), piperine ( Piper nigrum et longum ), and lobeline ( Lobelia inflata ) are derived from lysine. Piperidine alkaloids are of interest to many researchers because of their important biological activities. Precursors of piperidine alkaloids The precursor of piperidine alkaloids is a substrate for the piperidine alkaloid molecule as well as being the source of the piperidine alkaloid's nitrogen and skeleton. L-lysine is the precursor of piperidine alkaloids. It is α-ε-diaminocarbon acid, the homologue of L-ornithine, contains with one methylene group more than t...

  Most of the liquid crystals to be synthesized required the preparation of intermediate. Generally, producing a liquid crystal from an intermediate can save you time and money. Intermediates tend to be extremely reactive and short-lived, so they represent a low concentration in a chemical reaction compared with the amount of reactants or products. When describing intermediates, we need to take into account the reaction in which they are present. A short-lived species in one reaction might actually be considered stable in another. Manufacturing Steps of Liquid Crystal Materials Generally, there are three main steps in the manufacturing process of liquid crystal materials. Firstly, liquid crystal intermediates are synthesized from basic chemical raw materials. The second step is the synthesis of liquid crystal monomer from liquid crystal intermediates. In the third step, these electronic liquid crystal monomers are mixed in different proportions to achieve uniform and stable liquid ...
