Simultaneous optical trapping and magnetic micromanipulation of ferromagnetic iron-doped upconversion microparticles in six degrees of freedom
Autor: Nalupurackal, Gokul, M, Gunaseelan, Lokesh, Muruga, Vaippully, Rahul, Chauhan, Amit, Nanda, B. R. K., Sudakar, Chandran, Kotamarthi, Hema Chandra, Jannasch, Anita, Schffer, Erik, Senthilselvan, Jayaraman, Roy, Basudev
Optical trapping of magnetic Fe-oxide particles is notoriously difficult due to their high refractive indices, not to mention high absorptivity at the trapping infra-red wavelengths. We synthesize Fe co-doped NaYF4:Yb,Er ferromagnetic upconversion pa

Publikováno v: Fixed Point Theory and Algorithms for Sciences and Engineering, Vol 2022, Iss 1, Pp 1-14 (2022)
Abstract In this paper, we prove some common coupled fixed-point theorems on complete C ⋆ $\mathscr{C}^{\star}$ -algebra-valued partial b-metric spaces. Some of the well-known facts in the literature are generalized and expanded by the results show

Upconverting particles like Yb and Er-doped NaYF _4 are known to heat up after illumination with light at pump wavelength due to inefficient upconversion processes. Here we show that NaYF _4 particles which have been co-doped not only with Yb and Er

Trapped in Out-of-Equilibrium Stationary State: Hot Brownian Motion in Optically Trapped Upconverting Nanoparticles
Autor: Sumeet Kumar, Amrendra Kumar, M. Gunaseelan, Rahul Vaippully, Dipanjan Chakraborty, Jayaraman Senthilselvan, Basudev Roy
Publikováno v: Frontiers in Physics, Vol 8 (2020)
Upconverting nanoparticles typically absorb low frequency radiation and emit at higher frequencies relying upon multiphoton processes. One such type of particle is NaYF4:Yb,Er, which absorbs at 975 nm while emitting in visible radiation. Such particl

Optical tweezers have revolutionised micromanipulation from physics and biology to material science. However, the high laser power involved in optical trapping can damage biological samples. In this context, indirect trapping of microparticles and ob
