Background Miniature ion trap mass spectrometer enables mass-to-charge ratio analysis of
ions via quadrupole field in a low vacuum environment. It plays an important role in on-site …

The main purpose of this paper is to introduce a boundary layer analysis for the fluid flow
andheat transfer characteristics of an incompressible nanofluid flowing over a permeable …

This paper discusses the optimal control of pressure using the zero-gradient control (ZGC)
approach. It is applied for the first time in the study to control the optimal pressure of …

The paper reports on some theoretical studies concerning the impulsional mode of a
quadrupole mass filter (QMF) supplied with a new periodic impulsional radio frequency …

In this article, we investigate the theoretical study of the magnetohy-drodynamic (MHD) non-
orthogonal stagnation point flow of a nanofluid towards a stretching. The partial differential …

RATIONALE The capabilities and performances of a quadrupole ion trap under damping
force based on collisional cooling is of particular importance in high‐resolution mass …

Quadrupole ion trap mass analyzer with a simplified geometry, namely, the cylindrical ion
trap (CIT), has been shown to be well-suited using in miniature mass spectrometry and even …

In this article, fractional calculus has been applied to study the motion of ions in a three-
dimensional radio frequency quadrupole ion trap; we have called this arrangement a …

Abstract The Brownian motion or Wiener process, as the physical model of the stochastic
procedure, is observed as an indexed collection random variables. Stochastic procedure are …

The employment of the fuzzy method to solve differential equations has been well studied. In
this article, Mathieu differential equations of the quadrupole mass filter (QMF) have been …
