The work of the Polymeric Materials Team at the NPL is summarised, identifying the scientific focus of the work and the measurement techniques available.
The demands of quantum metrology and nanoscience are driving the requirements for single particle detection capability across a wide variety of physics, including quantum information processing (QIP), single photon detection, NEMS, nanomagnetism and spintronics.
Thermodynamically based modelling provides improved understanding and prediction of processes; more efficient direction of experiments; energy savings and avoidance of pollution and corrosion. The rigor of a thermodynamically based approach gives extra confidence and supports regulatory conformance.
All measurement systems have a resolution limited by random fluctuations (noise) or by variations in parameters with time (drift). The Allan deviation statistical method allows different noise and drift types to be readily identified at various timescales.
This poster shows piezoresponse force microscopy data for a range of compositions of the multiferroic material bismuth ferrite lead titanate.
Nanoscale imaging of non-resonant Raman-active polystyrene (PS)-polymethyl methacrylate (PMMA) polymer-blend thin films using Tip-enhanced Raman spectroscopy (TERS) is reported for the first time in this poster.
Instruments based on direct stochastic optical reconstruction microscopy (dSTORM) are used to image the absorption of proteins by cells.
Recent advances in thermocouple development have resulted in ultra-stable Pt/Pd thermocouples. These are now available commercially.
Recently there have been a number of new designs of micro-CMM probes. However, there are still some issues with probe design that need addressing.
Collaborative work with the University of Cambridge demonstrates the power of the super-resolution imaging technique dSTORM (direct Stochastic Optical Reconstruction Microscopy).
The spatial uniformity of transmittance of most optical components evaluated was shown to exhibit fine structure which may introduce significant uncertainties in high accuracy radiometric measurements.

Light microscopes have a resolution limit of around 250 nanometres (nm), which means anything smaller will appear blurred.
Photoelectrochemical activity screening of dyes on TiO2 surfaces is becoming increasingly relevant as industry tries to expand commercialisation of dye-sensitized solar cells (DSSCs).
