The Malvern Panalytical compositional analysis coupled with GPC can provide the key to characterizing copolymers to the next level. In this application note you will find out how we analytically breakdown copolymers into their component parts and what extra information we get when we do so. The specific examples analyzed in this application note are blends of polystyrene and polymethylmethacrylate, ...

Prof. Saúl Loaiza shares the importance of robust quality control in mineral analysis by using high-quality in-the-field analyzers Published on SelectScience® on 8 June 2022 To get the big picture to fall into place, we must look at the smaller things. Every aspect of our lives – our buildings, our cars, products in our homes, and the food that we eat – needs to be safe and of high quality, ...

IntroductionA new mineral with the composition Al2(PO4)(SO4)(OH,F)·7H2O was found on the dump of the Lichtenberg open cast, Ronneburg, Thuringia, Germany. In the open cast and surrounding mines uranium-bearing alum shale was mined from 1951 to 1990. The Ronneburg mining area was one of the largest uranium producers in Europe. The new mineral is an alteration product of pyrite and fluorapatite ...

Polymer solids can have a range of mechanical properties, at one extreme they can be very soft and elastic and at the other they can be immensely strong and rigid. Their mechanical properties can change with external conditions such as temperature and pressure. They can be used for a large range of applications from protective coatings to containers and building materials. The science of ...

Global demand for graphite is soaring, driven by the clean energy transition to electric cars and battery energy storage systems, as graphite is used to make lithium-ion battery anodes. The properties that make it a great anode material also lends itself to many other innovative areas of research, such as specialist coatings and inks. For a given application, the particle size and particle ...

In the field of protein therapeutics, a protein-polymer conjugation strategy can improve the protein’s clinical potential by overcoming some of the challenges, such as physiochemical instability, immunogenicity and suboptimal circulation half-life.[1][2] This strategy is the covalent modification of a therapeutic protein with a polymer of biological or synthetic origin. A commonly used polymer ...

This technical note discusses DLS method development with the Zetasizer Advance series and highlighted the various factors that need to be considered. These include cell selection, instrument verification, sample preparation, measurement set up and results analysis.

The spectacular success of the Covid-19 vaccines has brought to global attention the potential of mRNA as medicines. It has also helped emphasize for the broader public that there are other types of RNA with a huge therapeutic potential, such as short interfering RNA (siRNA). Although they share the fundamental structure —they are both polymers of ribonucleic acids⁠—there are some notable ...

Modern batteries, like Li-ion, have revolutionized our day-to-day life – from enabling smart mobile devices to pollution-free electric cars and intelligent power-management solutions. Batteries also hold the potential to be economical solutions for mass energy storage, complementing renewable energy resources for power grid applications. Irrespective of the cathode chemistry, which can be ...

In this application note field application scientist, Dr Agatha Rosenthal discusses how the MicroCal PEAQ DSC can be used to analyze the thermal stability of mRNA-LNP formulations.
