This paper compares two laser-assisted processes developed by the authors for the fabrication of microwave devices based on nanowire arrays loaded inside porous alumina templates. Pros and cons of each process are discussed in terms of accuracy, reproducibility and ease of fabrication. A comparison with lithography technique is also provided. The efficiency of the laser-assisted process is demonstrated through the realization of substrate integrated waveguide (SIW) based devices. A Nanowired SIW line is firstly presented. It operates between 8.5 and 17 GHz, corresponding to the first and second cut-off frequency of the waveguide, respectively. Next, a Nanowired SIW isolator is demonstrated. It shows a nonreciprocal isolation of 12 dB (corresponding to 4.4 dB/cm), observed in absence of a DC magnetic field, and achieved through an adequate positioning of ferromagnetic nanowires inside the waveguide cavity.

Abstract Recently, the three-dimensional (3D) printing technique has attracted much attention for creating objects of arbitrary shape and manufacturing. For the first time, in this work, we present the fabrication of an inkjet printed low-cost 3D temperature sensor on a 3D-shaped thermoplastic substrate suitable for packaging, flexible electronics, and other printed applications. The design, fabrication, and testing of a 3D printed temperature sensor are presented. The sensor pattern is designed using a computer-aided design program and fabricated by drop-on-demand inkjet printing using a magnetostrictive inkjet printhead at room temperature. The sensor pattern is printed using commercially available conductive silver nanoparticle ink. A moving speed of 90 mm/min is chosen to print the sensor pattern. The inkjet printed temperature sensor is demonstrated, and it is characterized by good electrical properties, exhibiting good sensitivity and linearity. The results indicate that 3D inkjet printing technology may have great potential for applications in sensor fabrication.

Despite major improvements in diagnostics and interventional therapies, cardiovascular diseases remain a major healthcare and socio-economic burden both in western and developing countries, in which this burden is increasing in closecorrelation to economic growth. Health authorities and the general population have started to recognize that the fightagainst these diseases can only be won if their burden is faced by increasing our investment on interventions in lifestylechanges and prevention. There is an overwhelming evidence of the efficacy of secondary prevention initiatives includingcardiac rehabilitation in terms of reduction in morbidity and mortality. However, secondary prevention is still too poorlyimplemented in clinical practice, often only on selected populations and over a limited period of time. The developmentof systematic and full comprehensive preventive programmes is warranted, integrated in the organization ofnational health systems. Furthermore, systematic monitoring of the process of delivery and outcomes is a necessity.

Abstract Carpenter 430FR Solenoid Quality stainless steel is a ferritic chromium-iron alloy developed especially for A.C. and D.C. magnetic circuit applications such as solenoid valve core components and electromagnetic relay cores. The electrical resistivity of 430FR is approximately 25% higher than other commercially available 430F stainless. Increased electrical resistivity provides better performance of magnetic components, particularly at power frequencies and high magnetic flux density. This datasheet provides information on composition, physical properties, and hardness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-337. Producer or source: Carpenter.
