Monomers, mostly organic, are a type of molecules that have the ability to chemically bond with other molecules in a long chain. Monomers are usually unsaturated, cyclic or contain two or more functional groups of low molecular compounds, mainly including acrylic, epoxy, styrene, alcohol, acid anhydride, etc. They are the most important raw materials to polymers by forming chemical bonds or binding supramolecular through a process called polymerization. Common Monomers and Their Functions Different types of monomers can give different functions to polymer materials, so that on the basis of the original mechanical properties, it not only has the function of transferring, transforming or storing substances, but also has the function of chemical reactivity, photosensitivity, conductivity, catalysis, biocompatibility, pharmacology, selective separation, energy conversion, magnetism and other functions.

In general, magnesium alloys show lower mechanical performance in comparison with other metal alloys. Grain refinement and precipitation strengthening are the two primary methods to improve the strength and ductility for magnesium alloys. Hence, commercial magnesium-zinc-zirconium (ZK) alloys were designed and are widely used. The ZK series magnesium alloys have good strength and ductility due to zinc addition for precipitation strengthening and zirconium addition for grain refinement. While with increasing content of Zn, ZK series magnesium alloys become more susceptible to solidification cracking. Because of the good casting properties, hot working properties and corrosion resistance, ZK series magnesium alloys can be used in aviation, aerospace, transportation, chemical industries. Apart from structural applications, it has been reported that the ZK series magnesium alloys are promising for biodegradable implants applications because they have slower corrosion rates.

Microbial metabolites are intermediate or end products of microbial metabolism, which are involved in the various biochemical reactions in microorganisms. Microbial metabolites include various organic compounds, such as amino acids, nucleotides, fermented alcohols, signal molecules, growth factors, etc. They play an immense role in healthcare, and are a major source of essential nutrients for all life forms. The inherent characteristic of microbial metabolites is their origin, that is to say their specific producer. Different producers are related to various biological activities and functions of microbial metabolites. Microbial metabolites are classified into primary metabolites and secondary metabolites[1]. Primary metabolites Metabolites produced in early phase of microbial growth are involved in cellular growth and development and are termed as primary metabolites.

Malachite green (MG) and crystal violet (CV) are synthetic basic industrial dyes of triphenylmethane. In the past, many countries used MG and CV as insecticides and fungicides to be widely used in aquaculture to kill ectoparasites and mold in fish eggs. Later scientific research found that malachite green and leuco malachite green remain in aquatic products and the environment for a long time. The MG and CV chemical functional groups "triphenylmethane" have been confirmed to have high toxicity, high residue, carcinogenic, teratogenic, mutagenic and other side effects. In addition, the discharge of wastewater containing malachite green and crystal violet will pollute the water environment. Therefore, the United States, Canada, Japan, Europe and the United States and other countries or organizations have listed it as a banned drug for aquaculture. Malachite Green and Crystal Violet Residue Testing Service After entering aquatic animals, MG and CV are rapidly metabolized i

Canine disease diagnosis is an important aspect of veterinary medicine aimed at recognizing and determining the presence of disease in dogs. Accurate and timely diagnosis is essential for the effective treatment, management and prevention of canine diseases. Canine diseases range from common ailments to more serious diseases that can be life-threatening. Early and accurate diagnosis enables veterinarians to provide appropriate treatment, prevent disease progression, and improve the overall health and well-being of the dog. Diagnosis also plays a vital role in disease surveillance, outbreak control and monitoring the effectiveness of preventative measures. The canine disease diagnosis test kits utilize advanced molecular biology techniques such as enzyme-linked immunosorbent assay (ELISA) or lateral flow assays (LFA) with high sensitivity and specificity. These techniques target specific pathogen gene markers or sequences to ensure accurate results and reliable diagnosis. Multipl

Atomic layer deposition (ALD) is a special CVD that can be deposited at the atomic level. It can form very smooth, uniform thickness, highly dense, and alternating layers of different materials with minimal defects. CVD / ALD processes are highly attractive, through which thin films that meet specifications and are uniform and with precise thickness control can be grown. CVD is suitable for manufacturing optical storage media and manufacturing semiconductor devices. With more precise control of film formation, ALD is becoming more and more attractive for depositing thin films through microelectronic device applications, such as ferroelectric memory, integrated circuits, MEMS, thin-film capacitors, and new high-k gate dielectrics. They are also essential for advancing the technology of electroluminescent devices. CVD and ALD Precursors.pngFig 1.

Volatile organic compounds (VOCs) are the precursors of photochemical smog, which can be divided into hydrocarbon, halogenated hydrocarbon and VOCs containing oxygen. In addition to participating in the photochemical reaction in the atmosphere to form ozone, volatile organic compounds can be further oxidized, affecting the oxidation of the atmosphere and eventually forming secondary organic aerosols, resulting in the deterioration of visibility, which is an important pollutant in the formation of complex atmospheric pollution. In addition, VOCs are easily absorbed by human skin and mucosa, causing acute damage to human health. Some of the substances are also carcinogenic, teratogenic and mutagenic. VOCs in the outdoor environment mainly come from industrial waste gas from fuel burning and transportation, automobile exhaust gas and photochemical pollution, etc. Indoor smoke mainly results from combustion products such as coal and natural gas, smoking, heating and cooking, constructio

Nimustine hydrochloride is an active pharmaceutical ingredient used in the treatment of malignant brain tumors. Introduction of malignant brain tumors Malignant brain tumors can be divided into primary and secondary malignant brain tumors. Primary malignant brain tumors mean the cancer starts in the brain, while secondary malignant brain tumors mean the cancer starts somewhere else in the body and then metastasizes to the brain. The incidence of the latter is about 10 times that of the former. Meningioma brain tumors usually come with no symptoms, but as they grow gradually, patients may experience the following symptoms: Seizures Memory loss Speech problems Headache Loss of smell Hearing disability Numbness Blurred vision If left untreated, malignant brain tumors can rapidly grow and spread to other areas of the brain and spinal cord.
