Despite scientific and technological advances in the field of assistive technology (AT) for people with visual impairment (VI), technological designs are frequently based on a poor understanding of the physical and social context of use, resulting in devic ...
The implementation of non-user-centered design is sometimes effective for traditionally mass-produced items; however, these methods do not take into account local needs, resources, and cultures, and the history of individual people and communities in low- ...
Field Asymmetric IonMobility Spectrometry (FAIMS) is a very promising technique for chemical detection. FAIMS systems are portable, highly sensitive, relatively inexpensive and can work at atmospheric conditions. These attributes make it a very desirable t ...
Ionization efficiency is an important factor for ion sources in mass spectrometry and ion mobility spectrometry. Using helium as the discharge gas, acetone as the sample, and high-field asymmetric ion mobility spectrometry (FAIMS) as the ion detection meth ...
We presented the conduction mechanism investigation of porous silicon/p-Si heterojunction fabricated on low resistivity crystalline silicon by electrochemical anodization. Measurements of the current - voltage I(V) and capacitance - voltage C(V) characteri ...
