Determination of Polymer Blend Composition
The blending of two or more polymers is becoming a common method for developing new materials for demanding applications such as impact-resistant parts and packaging films.
Isothermal Microcalorimetry to Monitor Bacteria Growth
There has been significant work done looking at using IMC to characterize the growth patterns of bacteria3-9 and even converting isothermal microcalorimetry data into biologically meaningful data such as growth rate, lag phase, or maximum growth.
DSC Analysis of the Effect of Calcium Stearate on Crystallization of Polypropylene Nucleated with Sodium Benzoate – Modeling a PP Recycle Stream
This note demonstrates the utility of differential scanning calorimeter (DSC) measurements in evaluating the effects of an antagonistic interaction of two common additives that may be found in a mechanical recycle stream of polypropylene (PP).
Study on Energy Metabolism of Food Microorganisms with an Isothermal Microcalorimeter
This app note introduces the application of the measurement of metabolizable energy for growth of living organisms in food processing.
Evaluating Fatigue Characteristics and Heat Generation in Silica ‘Green Tire Recipe’ and Conventional Carbon Black Filled Rubber
This article investigates the flexing properties and heat generation of rubber mixtures of styrene butadiene rubber and butadiene rubber, with silica and carbon black as fillers, using Goodrich Flexometer test or Heat Build-up.7
Liquid Cell Testing via Heat Flow Meter Method
The thermal properties of liquids can be determined through the Heat Flow Meter Method. This is achieved with the DTC-300 instrument, a General Purpose Heat Flow Meter. Though a ‘standard’ sample tested via HFM is a solid disc of varying thickness, the implementation of an optional test cell allows for liquids to be tested as well, provided that they are in the range of 0.1 – 1.0 W/m·K.
Thermal Analysis of Lithium-Ion Battery Electrolytes for Low Temperature Performance
Two commercially available electrolytes are evaluated in this work to understand transitions at low temperatures which may impact battery performance.
Effect of Moisture and Substrate Material on Wall Friction Angle of Carboxymethyl Cellulose Powder
This work investigates the influence of moisture content and substrate material on the wall friction of carboxymethyl cellulose powder, which is used as an excipient in tablet formulations.
Epoxy Powder Rheology: Impact of Temperature on Flow and Shear Properties
TA Instruments Powder Rheology Accessory for Temperature Control is used to study a filled epoxy resin for powder coatings. The results show that care must be taken in storage and processing, even at temperatures below the glass transition due to the effects on flowability and cohesion.
Safety Evaluation of Lithium-ion Battery Cathode and Anode Materials Using Differential Scanning Calorimetry
In this note, a lithium nickel manganese cobalt (NMC) cathode and graphite anode are evaluated, finding higher reaction energy in the cathode, and increasing thermal stability with decreasing state-of-charge.
