HD Scanning Thermal Microscopy (HD SThM) allows studying local thermal properties simultaneously with QNM measurements. From the hardware point of view it was implemented using AppNano VertiSense™ thermocouple probes. The thermal conductivity and temperature mapping modes (CMM, TMM) can be realized by positioning the AFM laser at the end or the central part of the probe, respectively. HD mode working principle allows exceptional spatial resolution of SThM measurements in comparison to conventional Amplitude Modulation (AM) mode. That was demonstrated in TMM of a microheater sample. SThM and HybriD mode is the winning combination for distinguishing between the constituents of polymer blends as demonstrated in the example of a blend of polystyrene (PS) with low density polyethylene (LDPE) (see below). The difference in thermal conductivity of the polymers (PS – 0.12 W/mK; LDPE – 0.33 W/mK) allows the assignment of the colder matrix to LDPE and the hotter islands to PS.

500g glass jar (can be ordered also in 1300g plastic jars) SELECTION REGION: Tula region Meadow May motley-grass honey is one of the most popular and widespread varieties. It is unique because it contains a lot of pollen from different plants of the central part of Russia. Nowhere else in the world you can find such a combination: on average, from 15 to 35 plants. This type is characterized by a spicy, bright honey aroma and a brighter, warmer color. The main honey plants are clover, chamomile, sunflower, sage and thyme. This honey boosts the immune system, fights viral infections, removes wastes and toxins, accelerates metabolism and improves the digestive system.
