Malvern Instruments Discusses GPC/SEC Analysis of Polymer Solutions Used in Inkjet Printing
| By Malvern Instruments
Inkjet printing of polymer solutions is an area of interest for depositing precise, high-throughput patterns of functional polymer. The applications of the polymer patterns include OLEDs, organic circuits, and textiles. The efficacy of this printed pattern can be negatively impacted by the concentration and viscosity of the polymer solution, the molecular weight and molecular weight distribution of the polymer, and level of branching in the polymer. Therefore, it is of keen interest to understand the effect of inkjet printing on the degradation of polymers. In this application note, the molecular weight (MW) and molecular weight distribution (MWD) of various polymers is shown as a function of time during inkjet printing. The data shown in this application note is from references [1-2].

Malvern Instruments compares metal powders from different atomization processes using automated image analysis
| By Malvern Instruments
Image analysis is an ideal tool for characterizing the size and shape distributions of atomized metal powders. The manufacture of complex shaped metal parts by Metal Injection Molding (MIM) is a growing industry. The shape and size of metal powders play an important role in determining process efficiency and properties of the final MIM components. Spherical powder particles are typically favored by MIM manufacturers looking to achieve best tolerances and properties in final components. Therefore, it is important to monitor atomized powder to ensure that particles of the desired shape and size are produced.

Malvern Instruments Explores Nanobubble Applications and Characterization
| By Malvern Instruments
Malvern Instruments conducts an in depth review of ultra-fine bubble (nanobubble) applications and characterization examples. The generation, measurement, and applied technologies of so-called nanobubbles or ultra-fine bubbles, with diameter ranging from tens to hundreds of nanometers, are evolving dramatically in recent years. The unique properties of nanobubbles makes them attractive for a number of applications such as facility cleaning, food disinfection, and water treatment, as well as possibilities in fields such as disinfecting food products, pharmaceutical delivery, decontamination, and manufacturing of functional materials. Preliminary market research conducted by the Fine Bubble Industries Association shows the size of the fine bubble business increasing from USD 20 million in 2010 to USD 4.3 billion in 2020.

Synergy of Complementary Nanomaterial Characterization Techniques: NTA+DLS
| By Malvern Instruments
Dynamic Light Scattering (DLS) is a mature and proven technology for nanomaterial characterization. Nanoparticle Tracking Analysis (NTA) is a more recent addition to the spectrum of particle characterization techniques and has many similarities to DLS, leading to some confusion as to their relative capabilities. The broad range of measurement capabilities for each technique is complementary in nature, providing a wealth of valuable information. The differences between the two techniques allow the data from one technology to validate and support the other.

Using the Zetasizer Nano to Optimize Formulation Stability
| By Malvern Instruments
Formulation development is a critical activity for many industries, from pharmaceuticals, to paints and coatings. Indeed, it is estimated that in the UK alone, sales of formulated products amount to some £180 billion per year1. This means that getting formulation ‘right’ is an important goal, with considerable value attached to it. Stability is a crucial attribute for many products with a direct impact on performance, shelf-life, kerb appeal and ultimately, worth. A systematic approach to understanding and developing stability can therefore be extremely helpful in improving the likelihood of success in long-term stability trials and accelerating formulation. The Zetasizer range from Malvern is the world’s most widely used system for nanoparticle, colloid and protein size and zeta potential measurements. In this whitepaper, we examine how these capabilities can be exploited to develop stable dispersions.

Time to Spec up? Top Five Reasons to Replace a Viscometer with a Rheomete
| By Malvern Instruments
Is your viscometer approaching the end of its life? Are you starting to feel that your trial and error, ‘rheology-light’ approach to formulation is becoming dated? Or are there longstanding product performance issues that you’re failing to gain traction with, where you suspect rheology may hold the answer?

Biophysical Characterization of Epigenetic Protein Interactions
| By Malvern Instruments
Epigenetics is the study of heritable changes in gene expression caused by nongenetic mechanisms, without alterations in gene structure or DNA sequence. The epigenetic state of a cell evolves during the cellular differentiation and development of an organism, and epigenetic changes are linked to cellular reprogramming. Because epigenetic mechanisms may also be responsible for the integration of environmental responses at he cellular level, they potentially play an important role in the development of som diseases.

Overcoming and Quantifying 'Wall Slip' in Measurements from a Rotational Rheometer
| By Malvern Instruments
When making shear rheological measurements on structured liquids, in particular suspensions, emulsions or foams there is a high probability that the measurement may be affected by a phenomenon known as 'wall slip'. Wall slip generally results from a localdepletion of the dispersed phase near the geometry walls, effectively forming a lubrication layer at the surface. As a consequence bulk rheological properties are no longer being accurately measured leading to an underestimation of the true viscosity. A similar effect can be observed when measuring solid like materials where there is insufficient friction between the sample and the wall to support the applied stress.

Preformulation and Stability Studies of Biotherapeutics Using DSC
| By Malvern Instruments
The use of biotherapeutics, such as antibodies and other protein molecules, to treat diseases is a rapidly growing field in the pharmaceutical industry.Biotherapeutics are often required at high concentrations and multiple doses, hence a manufacturer must produce kilogram quantities or more of the protein drug. The manufacturing process for biotherapeutics involves protein expression in thousands of liters of bioreactor medium followed by a purification process using large-scale chromatography columns and filtration systems.
