Herein, a single-step production for the development of gas sensing devices from unsubstituted and hexadecafluorinated metal phthalocyanines (MPc, M = Fe2+ Co2+) is explained. The preparation sensor by direct growth nanowires on interdigitated electrodes vapor transport synthesized MPc precursors discussed, emphasizing approach. Results using as-prepared detection NH3 NO2 in ppb range are shown. In agreement with similar materials, response recovery times fitted double-exponential model gave...

The development of rapid prototyping techniques for the fabrication microelectronic structures has seen growth over past decade. In particular, laser-induced forward transfer (LIFT) is a non-lithographic direct-write technique that offers advantages high speed / throughput, resolution, materials versatility, and substrate compatibility. Because degree control size shape printed material, wide range components, including interconnects, antennas, sensors, become possible using LIFT. this...

The use of laser induced forward transfer (LIFT) techniques for printing materials sensor and electronics applications is growing as additive manufacturing expands into the fabrication functional structures. LIFT capable achieving high speed/throughput, high-resolution patterns a wide range over many types substrates in flexible-hybrid electronics. In applications, sacrificial or laser-absorbing donor layer required despite fact that it can only be used once. This because various release...

The increasing interest for dedicated analysis of single particles at microscopic scales, such as biological cells, has led researchers to create micro-fluidic systems capable trapping in a liquid flow. most common mechanism is by physical obstruction, which simple, but it its limitations. For instance, these particle selectivity poor because all the that pass through channel may get pin down against obstruction regardless size and shape [Di Carlo et al., Tan Nilsson al.]. In addition,...
