Nodularity Measurement Carbon in the form of graphite is often used as an additive in the production of cast iron, amounting to 2 to 4 percent by weight or 6 to 10 percent by volume in typical castings. The microstructure of graphite within cast iron significantly affects the mechanical properties of the casting. When graphite takes the form of thin flakes the result is flake cast iron, which is hard and brittle. When graphite arranges itself as spherical nodules the result is ductile cast iron, which is softer and more malleable than flake cast iron. The relative high strength and toughness of ductile cast iron provides advantages in many structural applications including automotive crankshafts, pistons and cylinder heads. Both flake cast and ductile cast iron are made by mixing carbon, silicon, and other additives into molten iron. Part of the mixing of elements is often done in the final mould. If the mixing is non-uniform or the casting process is not optimal, it is possible to make a casting with nodularity variations or with inclusions of flake cast iron present in the ductile cast iron. Since the type of result will significantly change the mechanical properties of the metal, foundries should check the uniformity of ductile cast iron. It is important to ensure that the distribution of graphite in the die casting is uniform and also that the graphite inclusions are present in the correct form: nodules rather than flakes. STEMart uses various methods to check the uniformity and form of the graphite in the die casting.

Protein is a complex organic compound composed of amino acids. Due to the hydrophilicity, hydrophobicity, positive charge, negative charge and other characteristics of amino acid residues, it can be folded into a precise 3D structure through the interaction between the residues. The sequence of amino acids determines the unique 3D structure of each protein and its specific functions. Protein participates in almost every process in the cell and is necessary to maintain the structure and function of human tissues and organs. Protein folding errors can induce a variety of degenerative diseases, such as Parkinson's disease, Alzheimer's disease, frostbite, and senile heart failure. Therefore, imaging analysis of the folding process of proteins is of great significance for the early diagnosis and treatment of diseases.

Metabolism is a term that describes the set of life-sustaining chemical reactions in organisms. It can be divided into two categories: catabolism, the breakdown of molecules, and anabolism, the synthesis of molecules. Metabolism is tightly linked to the availability of nutrients such as proteins, lipids and carbohydrates. Metabolic pathways are a series of chemical reactions of metabolism, which are catalyzed by a sequence of enzymes. However, metabolic signaling pathways refer to the cellular signaling transductions that respond to metabolic state and regulate cellular events to maintain cell and organismal homeostasis. Dysregulation of these pathways is associated width metabolic diseases such as obesity, type 2 diabetes, as well as cancer and aging.

Materials testing is used to understand how your materials will perform or react under a wide variety of stresses. Materials testing can also supply important information about the materials you are developing or incorporating into products to ensure they are in compliance with the expected specifications. The data collected during testing and the final test results can be very useful to engineers, designers, production managers and others. STEMart can conduct a large range of material analysis and characterization under standard guidelines and methods, and also provide custom testing according to clients' testing purposes and applications of the testing requirements.

Dengue Virus (Serotypes 1-4) Antiviral Services Dengue virus is an enveloped single-stranded positive-sense RNA virus, which belongs to the family of Flaviviridae. Dengue virus has approximately 11,000 nucleotides in length that encodes three structural (C, Env, M) and seven non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). There are four different serotypes of dengue virus (DENV 1-4) and the classification is based on structural antigens that induce type-specific antibodies at the time of infection. Dengue fever is an arthropod-borne disease caused by the dengue virus (DENV), mainly transmitted by Aedes aegypti mosquitoes. Dengue fever is the most popular mosquito-borne disease in the world. The dengue virus mainly spreads in tropical and subtropical regions, including Southeast Asia, the Americas, Africa, the Western Pacific, and the Eastern Mediterranean. Dengue virus research should be conducted using biosafety level 2 practices, equipment, and facility design. Laboratory diagnostic methods to confirm dengue virus infection may involve detection of virus, viral nucleic acid, antigen or antibody, or a combination of these techniques. The virus can be detected in serum, plasma, circulating blood cells, and other tissues for 4-5 days after onset. In the early stages of the disease, viral isolation, nucleic acid or antigen testing can be used to diagnose infection. At the end of the acute phase of infection, serology is the method of choice for diagnosis. Serological tests for dengue virus generally use IgM antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA), IgG ELISA, IgM capture and IgG capture ELISAs, anti-dengue virus IgA capture ELISA, and haemagglutination-inhibition (HI) test.
