  Emulsifiers  When you bite into a velvety slice of cake, pour a smooth salad dressing, or scoop up a spoonful of creamy ice cream, emulsifiers are working behind the scenes to create that perfect consistency. Often overlooked on ingredient labels, emulsifiers are the unsung heroes in the world of food production. They ensure that oil and water, two substances that naturally repel each other, blend together seamlessly, forming stable mixtures with the desired textures and flavors. In this blog, we’ll explore what emulsifiers are, how they work, and their vital role in food production, focusing on their ability to enhance textures, improve shelf life, and even make foods healthier. What Are Emulsifiers? Emulsifiers are substances that help combine two immiscible liquids—typically oil and water—into a smooth, stable mixture known as an emulsion. Without them, many food products would separate into unappetizing layers of oil and water. The simplest example of an emulsion ...

  Polyethyleneimine  Chemical Structure and Properties Polyethyleneimine (PEI) is a polymer made up of repeating units of ethyleneimine monomers. The monomer units are connected through secondary amine groups, which give PEI its unique branched structure. PEI is further classified based on its average molecular weight - low (600-5,000 Da), medium (5,000-25,000 Da) and high (>25,000 Da). PEI has a high density of amine functional groups which makes it cationic and water-soluble across all pH ranges. This key property arises due to the presence of primary, secondary and tertiary amino groups along its polymer backbone. PEI also has a high charge density that allows it to be an effective polyelectrolyte and bind strongly with anions like DNA or RNA. Its branched structure increases solubility and decreases viscosity compared to linear PEIs of similar molecular weight. Gene Delivery and Transfection One of the major applications of PEI is in gene delivery and transfection. ...

  Industrial Coatings  Industrial covering refer to protective paints, coatings and lining systems used for infrastructure, equipment and applications operating in demanding industrial settings. These heavy-duty coatings are designed to shield surfaces from corrosion, abrasion, chemicals, heat and other environmental stresses present in various industries. Some of the main sectors utilizing industrial covering include oil and gas, petrochemical, automotive, mining, power generation, wastewater treatment and infrastructure development amongst others. Types of Industrial Coatings There are different types of industrial covering suitable for diverse applications and environmental conditions: - Anticorrosive Coatings: Used for protecting metal surfaces like steel, non-ferrous alloys from corrosion in harsh, wet or salty environments. Some examples are epoxy, polyurethane, vinyl and alkyd coatings. - Chemical Resistant Coatings: Applied on surfaces that will be exposed to chem...

  UV Coatings Value  UV Coatings Technology and Applications Ultraviolet (UV) curable coatings, also known as UV coatings, cure and dry upon exposure to ultraviolet light. They are different from traditional thermoset coatings that cure through the application of heat. UV coatings offer several advantages over solvent-borne and thermally cured coatings. Some key characteristics of UV coating technology include: - UV absorbers - UV coatings contain photoinitiators or photoinitiating systems that absorb UV light energy and initiate the polymerization and curing process. Different types of photoinitiators can be used for different types of resins and applications. - Light curing - Upon exposure to UV light source such as mercury vapor, LED, or iron vapor lamps, the photoinitiators trigger a photochemical reaction that converts the liquid or paste-like resin into a cured dry protective film within seconds. - Solvent-free application - UV coatings are 100% solids and contain vi...

Refinery Catalyst  Refineries play a vital role in meeting the ever-growing demand for fuels like gasoline, diesel and jet fuel. These complex facilities convert crude oil into a variety of products through an array of processes like fractionation, cracking and reforming. However, the efficiency and yield of these processes heavily depend on the usage of specialized catalysts known as refinery catalysts. In this article, we explore the importance of refinery catalysts and how they help refineries operate smoothly. What are Refinery Catalysts? Refinery catalysts are substances that facilitate and accelerate chemical reactions during refining processes without undergoing any permanent chemical change themselves. They allow refineries to produce more fuels and valuable petrochemicals from crude oil in a cost-effective manner. Some common types of catalysts used in refineries include metal oxides, zeolites and metals like platinum, palladium, nickel and cobalt. They play a vital role i...
