Hydrogen Peroxide  Introduction Hydrogen peroxide (H2O2) is a chemical compound consisting of oxygen and hydrogen. With a chemical formula of H2O2, it is colorless and appears as a clear liquid, slightly more viscous than water. Hydrogen peroxide is naturally produced in small amounts by all aerobic organisms as a by-product of metabolic processes that use oxygen. However, it finds extensive applications in various industries as well as in our daily lives. Physical and Chemical Properties Hydrogen Peroxide is a pale blue, clear liquid that is slightly more viscous and dense than water. It has a pH of 4-5 and is considered unstable as it readily decomposes into water and oxygen. This decomposition process is catalyzed by light, heat or metal ions. Its chemical structure consists of two hydrogen atoms bonded to two oxygen atoms to form a hydrogen-oxygen bound. This bound makes it more reactive than water and it acts as a strong oxidizing agent in chemical reactions. At room temper...

  Flexible Packaging The flexible packaging industry has been growing steadily across Southeast Asian markets in recent years, driven by changing consumer lifestyles and preferences as well as economic growth in the region. Flexible packaging solutions such as plastic films, pouches, bags and wraps are finding increasing demand from both food and non-food applications. Increasing Consumption of Convenience and Ready-to-Eat Foods One of the major factors fueling the rise of flexible packaging is the growing consumption of convenience and ready-to-eat foods among urban populations in ASEAN countries. As more people lead busier lifestyles with less time to cook, preference for packaged foods that can be easily prepared or consumed on the go has grown tremendously. Flexible packaging formats such as stand-up pouches,queeze pouches and easy-to-open bags provide the perfect solution for foods like snacks, frozen meals, coffee and more. They allow makers to offer portion-controlled and...

Feldspar  Feldspar is a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as veins or masses in both intrusive and extrusive igneous rocks. They also form in low-grade metamorphic rocks through the gradual alteration of pre-existing igneous rocks. Commonly off-white to gray or pink in color, feldspars are an essential constituent in the majority of felsic igneous rocks. Forms and Composition Feldspar s belong to a solid solution series between albite (NaAlSi3O8) and anorthite (CaAl2Si2O8) end members. Based on the predominant alkali/alkaline earth metal composition, feldspars are divided into two main categories - plagioclase and potassium feldspar. Plagioclase, containing sodium, calcium and traces of potassium, makes up ~90% of igneous rocks worldwide. Sanidine and orthoclase are the most common potassium feldspars rich in potassium. The varied chemical composition of feldspars allows...

eSports   eSports has seen exponential growth over the past decade emerging as a billion dollar industry. With large tournament prize pools and millions of viewers, competitive video gaming has paved a path of its own to reach new heights. Beginnings of eSports The origins of eSports can be traced back to the 1970s when computer space tournaments were organized. However, it was not until the 1990s that eSports began to take off with the rise of multiplayer video games. Some of the early landmark events included the first international StarCraft tournament in Korea in 1996 and QuakeCon Doom tournaments starting in 1997 held in the US. Major gaming titles like StarCraft, Warcraft III, and Counter-Strike dominated the competitive scene attracting enthusiastic gamers and small live audiences. Rise of Major Tournaments With growing interest, prize pools at tournaments steadily increased throughout the 2000s. In 2011, the first League of Legends World Championship was held with ...

Automated Fiber Placements And Automated Tape Laying Machines Automated fiber placement (AFP) and automated tape laying (ATL) machines are two advanced manufacturing processes that have revolutionized the composites industry. These machines utilize computer-controlled robotic systems to precisely place fiber-reinforced composite tapes and prepregs onto large composite molds or tools to produce high-quality composite parts with extremely accurate fiber steering and placement. What is Automated Fiber Placement? Automated fiber placement (AFP) involves the use of a machine with a robotic end effector to lay down multiple plies or layers of dry composite materials, called tows, onto a tool or mold surface to build up a laminated composite structure. The AFP machine spools continuous strands of carbon fiber, glass fiber, or other composite fibers and places them onto the tool according to a pre-programmed sequence. AFP can consolidate multiple fiber tows into a single ply with very pre...

Lidocaine Patches  What are Lidocaine Patches? Lidocaine patches are a type of topical analgesic patch used to relieve pain. Lidocaine is a local anesthetic that works by reversing the sensations of pain signals sent to the brain. It temporarily blocks sodium channels in nerve cell membranes, inhibiting the conduction of pain signals. Lidocaine patches work by continuously delivering lidocaine through the skin directly to the skin and nerve endings below. This reduces discomfort and allows patients to do daily activities with less pain. How do Lidocaine Patches Work? Lidocaine patches contain 5% lidocaine formulated in an adhesive patch. When applied to intact skin, the patch adheres and releases lidocaine through the skin layers over a period of 12 hours. After penetrating the outer skin layers, the lidocaine is delivered to nociceptors - the nerve endings that detect pain signals. Here it prevents the nerve endings from sending those pain signals by blocking the neurotransmitt...

  Cell Processing Introduction Cells form the basic structural and functional units of all living organisms, from bacteria and plants to humans. Cell processing refers to the various techniques used for working with and manipulating cells outside their natural biological context. With advances in biotechnology, cell processing has enabled significant contributions to fields such as medicine, biomanufacturing, and regenerative therapies. Isolation and Purification of Cells The initial stage of any cell processing workflow involves isolating cells of interest from the original biological sample such as tissue or cell culture. Specific cells are then purified away from unwanted cell types using techniques like centrifugation, filtration or cell sorting. Cell isolation techniques work by exploiting differences in cell properties such as size, density or expression of specific cell surface markers between target and non-target cells. For example, immune cells can be isolated from who...
