Effect of the Refractive Index of Buffer Solutions in Evanescent Optical Biosensors
Evanescent field optical biosensors are label free sensors that measure the variation of the refractive index of the adsorbed layer onto a chip surface and translate this variation into surface concentration of the adsorbed molecule. The evanescent field

Buffer Index and Buffer Capacity for a Simple Buffer Solution
Journal of Chemical Education, 1997Many papers that present the buffering effect of the simple buffer solution consider the notion of buffer index and buffer capacity as being equivalent. Moreover, IUPAC defies them as the same thing. According to the definition of the authors who have introduced these two units, the paper shows that there is a large difference between them.

Buffer index in the titration of a monoprotic acid with a strong base
International Journal of Pharmaceutics, 1992Abstract Buffer solutions are of great worth in analysis, in chemical and pharmaceutical research, in physiology and other fields of science and technology. On the other hand, buffer capacity is subject to precise algebraic treatment by using differential calculus. The location of the maximum and inflexion points in the buffer index against pH and in

A Method for Cross-Layer Analysis of Transmit Buffer Delays in Message Index Domain
IEEE Transactions on Vehicular Technology, 2018In data transmission systems, quality-of-service constraints are commonly defined in the form of buffer overflow probability or delay violation probability at a transmitter buffer. Some of the studies that employ the large-deviation principle have taken the buffer overflow probability as the quality-of-service constraint and performed the associated ...

Buffer dependence of refractive index increments of protein solutions
Biopolymers, 1998The refractive index increment of a protein solution is a property not only of the protein, but also of the solvent. This is demonstrated theoretically and confirmed experimentally using analytical interferometry. © 1998 John Wiley & Sons, Inc.

On the buffer index of a single weak monoprotic acid system
International Journal of Pharmaceutics, 1996Abstract Mathematical consideration of the course of titration of a weak acid with a strong base shows that buffer index versus pH curve, π = f(pH), should contain two minima and one maximum under certain conditions, which coincides with the three inflection points of the pH versus fraction titrated, pH = f(T), curve.

Refractive index buffer enhanced out-of-plane coupling in silicon-on-insulator
2009 6th IEEE International Conference on Group IV Photonics, 2009A refractive index buffer enhanced grating coupler in Silicon-on-insulator (SOI) was demonstrated. By a PMMA cladding layer, the grating coupler with the efficiency of 44% and 3-dB bandwidth of > 40 nm was obtained.
