Advancing the emerging technologies of MEMS, especially relating to the applications, constitutes one of the most challenging tasks in today’s micromechanics. In addition to design, analysis, and fabrication capabilities, this task also requires advanced test methodologies for determination of functional characteristics of devices produced to enable verification of their operation as well as refinement and optimization of specific designs. The tools used can be categorized as analytical, computational, and experimental. Solutions using the tools from any one category alone do not usually provide all of the necessary information on MEMS and extensive merging, or hybridization, of the tools from different categories is used. One of the approaches employed in the development of micro-structures of contemporary interest, is based on a combined use of the analytical, computational, and experimental solutions (ACES) methodology. In this paper, applicability of the ACES methodology is illustrated by use of selected MEMS samples. The representative results presented in this paper indicate that the optical methodology is a viable tool for micro-scale measurements and, as such, it is particularly useful for development of MEMS, especially while considering MEMS reliability assessment. In fact, this methodology is being used in various manufacturing stages of MEMS for high-performance applications.

Abstract We modified the micro-scale spectrophotofluorometric method of Miceli et al. [Biochem. Med. 12, 348 (1975)] for the assay of "apparent" isoniazid (isoniazid plus acid-labile hydrazones) to improve its clinical application. We also adapted the method for determination of acetyl isoniazid. Data are presented showing how long plasma containing isoniazid may validly be stored. The applicability of the method was demonstrated in studies on children and small animals.

Abstract We report a new micro-scale (0.1-mL sample) turbidimetric method for determination of protein by use of benzethonium chloride in alkali. The method is highly specific for protein, has a higher sensitivity than the classic method of Lowry et al., and shows satisfactory reproducibility and recovery. The turbidity produced in our method is the same for albumin and gamma-globulin and is more stable than in Meulemans' method (in which sulfosalicylic acid is used) or in the method of Bossak et al. (in which trichloracetic acid is used). In contrast to Pesce and Strande's method, there is no manipulative loss of protein.

Abstract. In a cold magnetized plasma with two light ions of comparable gyrofrequencies and any species of heavy ions and/or charged dust particulates, a technique is developed to recover the relative charge density of the heavy plasma population and to estimate its effective averaged charge-to-mass ratio. Such results can be obtained without using mass spectrometer data but only the measurements of the ion plasma frequency, the electron gyro- and plasma frequencies as well as the two highest ion cutoff frequencies.
