From another side, continuous device downscaling identified by ITRS [10] imply the employment of both new device architectures (to improve short-channel effects (SCE) control) and new channel (to boost carrier mobility) and gate dielectric (to improve SCE control and minimize leakage currents simultaneously) materials.
At present, there is no sufficient generated knowledge and gathered experimental database on the reliability aspects in the devices with novel architecture and employing new materials thus creating a demand for an in-depth assessment of reliability issues in “novel” devices.
Difference in the initial space-charge conditions at the film-BOX interface, difference in oxide and interface charges build-up in both gate and buried oxides in the case of strained and non-strained materials as well as possible strain relaxation were considered.

Early-stage oxidation behavior of γγγγ''''-Ni3Al-based alloys with and without Pt addition Shigenari Hayashi1,a, Toshio Narita 1,b and Brian Gleeson2,c 1 Devision of Materials Science and Engineering, Hokkaido University, N13, W8, Kitaku, Sapporo, 060-8628, Japan 2 Department of Materials Science and Engineering, Iowa State University, Ames, Iowa, 50011-2300, USA a hayashi@eng.hokudai.ac.jp, bnarita@eng.hokudai.ac.jp, cbgleeson@iastate.edu Keywords: short-term oxidation, γ'-Ni3Al, Pt effect, Al2O3 scale, GD-OES analysis Abstract The early-stage oxidation behavior of γ'-Ni3Al-based alloys of composition (in at.%) Ni-22Al and Ni-22Al with 10, 20, and 30Pt was investigated in terms of oxidation kinetics, scale evolution and resulting composition profiles during heating to 1150ºC in air.
Several mechanisms have been proposed for this beneficial effect, including the postulation that Pt reduces both the negative effect of impurity sulfur and the extent of void formation at the oxide / alloy interface [5,6], or that the presence of Pt leads to the development of alloy protrusions into the oxide scale, which act to "key" the scale to the coating or alloy [7].

Effects of Fabrication Techniques and Durability Performance on Resistance of Fibre-Based PEDOT:PSS/GO pH Sweat Sensor Siti Nurazlina Zaidi1,a*, Khadijah Ismail1,b and Siti Nooraya Mohd Tawil1,c 1Faculty of Engineering, Universiti Pertahanan Nasional Malaysia, Kem Sungai Besi, 57000 Sungai Besi, Kuala Lumpur, MALAYSIA a2170308@alfateh.upnm.edu.my, bkhadijah@upnm.edu.my, cnooraya@upnm.edu.my Keywords: PEDOT:PSS/GO, pH sensor, sweat sensor, wearable electronics.
Hence, it is crucial to fabricate sweat sensor from non-toxic and durable materials that are flexible and stable for efficient detection.
Materials and Methods The experimental stages are categorised into material preparation and characterisation, and electrical characterisation of fabricated sensor via surface resistance measurements, as illustrated in Figure 1.
Therefore, this shows that the developed fibre sensor is able to withstand sweat absorption without any corrosion of coating materials during physical activities.

Approximately 15 nurses per hospital were interviewed, selected from areas with the most patient contact, as well as the responsible biomedical engineers.
Therefore, only the head nurses of each hospital ward, two nurses per ward, and the biomedical engineers within each healthcare institution were included.
In the healthcare sector, there is a tendency towards corrective rather than preventive measures, with emphasis on corrective maintenance due to workload, staff shortages, lack of materials and supplies, and budget constraints.
Fig. 5 shows a usage test from the perspective of a biomedical engineer, who would be responsible for managing and using the bot's settings [29].
