We report a one-pot chemical approach for the synthesis of highly monodisperse colloidal nanophosphors displaying bright upconversion luminescence under 980 nm excitation. This general method optimizes the synthesis with initial heating rates up to 100 °C/minute generating a rich family of nanoscale building blocks with distinct morphologies (spheres, rods, hexagonal prisms, and plates) and upc...

A study into the use of Solution Combustion Synthesis (SCS) method with glycine and citric acid to synthesize fine powders multicomponent solid solutions oxides rare earth (RE) metals (Nd, Sm, Eu, Gd, Dy, Ho) for preparation ceramic materials is presented. parameters 4-, 5-, 6-component entropy-stabilized (REOs) a C-type cubic structure are determined. The stability (ESOs) shown depend not only...

2-Thiohydantoin derivatives are produced by heating a mixture of thiourea and an alpha-amino acid. The method described offers the advantages of simplicity, low cost, easy work-up and scalability.

We present a concept for the post production modification of commercially available microfluidic devices to incorporate local temperature control, thus allowing for the exact alignment of heating structures with the existing features, e.g. wells, channels or valves, of a system. Specifically, we demonstrate the application of programmable local heating, controlled by computerized PI regulation,...

In this demonstration, we present a scalable low-cost solution to provide personalized home heating advice to households. Our solution uses a specially designed USB temperature logger, placed on top of the thermostat, to infer the operation of the heating system indirectly. Using additional external temperature data, available through the internet, it builds a simple thermal model of the home, ...

Producing solution-based metal nanoparticles that do not agglomerate at elevated temperatures remains challenging. We show that thermally stable Au and Cu nanoparticles can be prepared using polystyrene-poly(4-vinylpyridine) diblock copolymers as capping agents. These materials remain stable when their solutions are subjected to prolonged heating up to 160 °C for more than 48 h. These condition...
