Asymmetrical two-atom entanglement in a coated microsphere [PDF]

open access: yes, 2006
We study evolution of entanglement of two two-level atoms placed inside a multilayered microsphere. We show that due to inhomogeneity of the field modes this entanglement essentially depends on the atomic positions (asymmetrical entanglement) and also on

Microspheres of Mixed Proteins [PDF]

open access: yesChemistry – A European Journal, 2010
AbstractThis paper describes the synthesis of mixed proteinaceous microspheres (MPMs) by the sonochemical method. The current fundamental research follows the research of Suslick and co‐workers who have developed a method by which high‐intensity ultrasound is used to make aqueous suspensions of proteinaceous microcapsules filled with water‐insoluble ...

Investigation of microsphere-mediated cellular delivery by chemical, microscopic and gene expression analysis [PDF]

open access: yes, 2010
Amino functionalised cross-linked polystyrene microspheres of well defined sizes (0.2-2 mm) have been prepared and shown to be efficient and controllable delivery devices, capable of transporting anything from small dye molecules to bulky proteins into ...

Coupling of ultrathin tapered fibers with high-Q microsphere resonators at cryogenic temperatures and observation of phase-shift transition from undercoupling to overcoupling [PDF]

open access: yes, 2012
We cooled ultrathin tapered fibers to cryogenic temperatures and controllably coupled them with high-Q microsphere resonators at a wavelength close to the optical transition of diamond nitrogen vacancy centers.

PLGA Microspheres Incorporated Gelatin Scaffold: Microspheres Modulate Scaffold Properties [PDF]

open access: yesInternational Journal of Biomaterials, 2009
Freeze drying is one of the popular methods of fabrication for poly(lactide‐co‐glycolide) (PLGA) microspheres incorporated polymer scaffolds. However, the consequence of microspheres incorporation on physical and biological properties of scaffold has not been studied yet.

Experimental Study on Expansion Characteristics of Core-Shell and Polymeric Microspheres

open access: yesJournal of Nanotechnology, 2018
Traditional polymeric microsphere has several technical advantages in enhancing oil recovery. Nevertheless, its performance in some field application is unsatisfactory due to limited blockage strength.

Parameter determination and transformation for the focusing of dielectric microspheres illuminated by optical needle

open access: yesScientific Reports, 2017
By eliminating the spherical aberrations of microsphere we derived a simple but useful formula on the focusing of dielectric microsphere. On basis of this formula, not only can researchers determine the parameters of an optical microsphere system with ...

Compact, fiber-compatible, cascaded Raman laser [PDF]

open access: yes, 2003
Cascaded Raman Stokes lasing in an ultrahigh-Q silica microsphere resonator coupled to a tapered fiber is demonstrated and analyzed. With less than 900 μW of pump power near 980 nm, five cascaded Stokes lasing lines are generated.

Chitosan and Nanohydroxyapatite Roles in Physical and Chemical Characteristics of Gelatin/Chitosan/Nanohydroxyapatite Microspheres [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2010
The effects of chitosan/biopolymer (C/P) and nanohydroxyapatite/ biopolymer (nHA/P) weight ratios on particle size and its uniformity, cross-linking density and NH2 content of nano-hydroxyapatite/chitosan/gelatin (nHA/C/G) microspheres were investigated.

5-Gbit/s BER performance on an all fiber-optic add/drop device based on a taper-resonator-taper structure [PDF]

open access: yes, 2000
We present an all fiber-optic add/drop device based on a taper-resonator-taper structure with improved characteristics. Several gigahertz bandwidths are observed using microspheres having diameters ranging from 30 to 50 μm.
