A panel with international guests discussing their experiences of creating games with impact. The perspectives are from three different backgrounds - a US based philanthropic model, an EU funding policy angle, and from research/industry.

In the presented work, ZnO nanofiber sensor structures designed and fabricated using a standard microelectronic device technology were studied. The structures in the configuration of a resistor with chemically active ZnO multiple nanofibers deposited by electrospinning method were prepared. Investigation of inclusion in the process reactive- ly sputtered AlN insulating film to improve the robustness of the nanofibres on the substrate was undertaken. Selective wet chemical etching of AlN film using photoresist developers and a photoresist mask to define the sensor active area was studied. The Ti/Au ohmic contacts were fabricated using the lift-off photolithography process. To- pography of the sensor structure details was investigated using AFM. Electrical charac- terization by means of I-V measurements was made. Sensitivity to the physiologically relevant concentration of Bovine Serum Albumin in water solution was shown.

The observed spatial variability of arsenic substituted in pyrite (arsenian pyrite) was considered to study the nature of arsenic environment using synchrotron X-ray photoelectron spectroscopy. As 3d of arsenian pyrite has shown that bulk As, present as As(-I) in arsenian pyrite, may be an As–As dimer rather than as As–S. This argument was made due to shift in the bulk As 3d component to lower binding energy, a feature observed in the As-As dimer of loellingite (FeAs₂). The presence of a pronounced tail in the Fe 2p signal of arsenian pyrite, which is absent in loellingite, implies localised arsenic mineralisation in a dominating pyrite host. Possible As cluster formation producing a subtle shift in binding energy to lower values is also put forward. The surface component found at a binding energy of 41.3 eV in the As 3d of arsenian pyrite was ascribed to polymeric sites generated from surface reconstruction initiated upon fracture of As–As or As–S bond. Except for a polymeric sulphur component at a binding energy of 163.2 eV, the S 2p signal of pyrite and arsenian pyrite are equivalent at high excitation energy. Refereed/Peer-reviewed
