Highly effective antibacterial activity of lithium-dopedmagnesium oxide particles synthesized by the microwave-assisted hydrothermal route
MgO particles Bacterial inactivation Microwave-assisted hydrothermal route Li doping Antibacterial mechanism
2023/6/21
Nanocrystallinemagnesiumoxide with different lithiumdopingmolar contents were prepared by amicrowaveassisted hydrothermal route to improve their antibacterial activity. The as-preparedMgO and Li-doped...
Multi-photon evanescent wave (MPEW) excited lanthanidedoped upconverting nanoparticles (UCNPs) for fast single particles tracking and live cell membrane imaging

2016/12/2
We propose a novel multi-photon evanescent wave (MPEW) excitation modality for upconverting nanoparticles (UCNPs) based microscopy. Experimental results show this new imaging method for UCNPs is nonsc...
Quantization and superselection sectors III:Multiply connected spaces and indistinguishable particles
Quantum theory identical particles permutation invariance
2016/6/14
We reconsider the (non-relativistic) quantum theory of indistinguishable particles on the basis of Rieffel's notion of C*-algebraic (`strict') deformation quantization. Using this formalism, we relate...
Interpreting Quantum Mechanics in Terms of Random Discontinuous Motion of Particles
wave function Schrodinger's equation wavefunction collapse random discontinuous motion of particles de Broglie-Bohm theory many-worlds interpretation dynamical collapse theories
2016/6/13
This thesis is an attempt to reconstruct the conceptual foundations of quantum mechanics. First, we argue that the wave function in quantum mechanics is a description of random discontinuous motion of...
On Witness-Discernibility of Elementary Particles
Elementary particles Quantum mechanics Discernibility Leibniz’s principle Identity
2016/5/30
In the context of discussions about the nature of ‘identical particles’ and the status of Leibniz’s Principle of the Identity of Indiscernibles in Quantum Mechanics, a novel kind of physical discernib...
Quantum Logical Structures For Identical Particles
quantum logic-convex sets-indistinguishable particles
2016/5/30
In this work we discuss logical structures related to indistinguishable particles. Most of the framework used to develop these structures was presented in [17, 28] and in [20, 14, 15, 16]. We use thes...
How Classical Particles Emerge from the Quantum World
Identical particles quantum particles classical particles emergence
2016/5/30
The symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in exa...
Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...
Optomechanics of Levitated Dielectric Particles
Optomechanics optical trapping Brownian motion macroscopic quantum mechanics sensor
2016/1/23
We review recent works on optomechanics of optically trapped microspheres and nanoparticles in vacuum, which provide an ideal system for studying macroscopic quan-tum mechanics and ultrasensitive forc...
Experimental Observation of Entanglement Duality for Identical Particles
entanglement duality quantum indistinguishability quantum mechanics
2016/1/22
It was shown recently that entanglement of identical particles has a feature called dualism (Bose and Home 2013 Phys. Rev. Lett. 110 140404), which is funda-mentally connected with quantum indistingui...

2015/10/15
We investigate the long time/small mean-free-path asymptotic behavior of the solutions of a Vlasov-L′evy-Fokker-Planck equation and show that the asymptotic dynamics for the VLFP are described by an a...

Arctic stratosphere ozone layer polar stratospheric clouds sulphate aerosols
2015/9/16
Soon after the discovery of the Antarctic ozone hole it became clear that particles in the polar stratosphere had
an infl uence on the destruction of the ozone layer. Two major types of particles, su...
