Cp2TiCl/D2O/Mn, a formidable reagent for the deuteration of organic compounds
Cp2TiCl/D2O/Mn is an efficient combination, sustainable and cheap reagent that mediates the D-atom transfer from D2O to different
functional groups and can contribute to the synthesis of new deuterated organic compounds under friendly experimental conditions
and with great economic advantages.The Spanish MICINN (Project CTQ2015-70724-R)University of Sevill

Bose-Einstein Correlations for Mixed Neutral Mesons
Correlations are shown to arise in nonidentical mixed-particle pairs like
when observed in identical decay modes like in
multiparticle final states containing many partial waves. No enhancement is
found in any single partial wave and all partial wave analyses of the s-wave
threshold resonance and should give the same results for all decay
modes. In CP violation experiments where pairs are inclusively
produced and correlated decays into and leptonic modes are observed,
the CP-violating lepton asymmetry is enhanced by a factor of two in the
kinematic region where Bose enhancement occurs.Comment: 11 page
Selectivity and specificity: pros and cons in sensing
Sensing using specific and selective receptors
provides two very different but complementary strategies. This
Sensor Issues article will discuss the merits and challenges of
specific sensors, and selective sensors based on synthetic
arrays. We will examine where each has been successfully
applied to a sensing challenge, and then look at how a
combined approach could take elements of both to provide
new sensor platforms
Study of KS KL Coupled Decays and KL -Be Interactions with the CMD-2 Detector at VEPP-2M Collider
The integrated luminosity about 4000 inverse nanobarn of around phi meson
mass ( 5 millions of phi mesons) has been collected with the CMD-2 detector at
the VEPP-2M collider. A latest analysis of the KS KL coupled decays based on 30
% of available data is presented in this paper.
The KS KL pairs from phi meson decays were reconstructed in the drift chamber
when both kaons decayed into two charged particles. From a sample of 1423
coupled decays a selection of candidates to the CP violating KL into pi+ pi-
decay was performed. CP violating decays were not identified because of the
domination of events with a KL regenerating at the Be beam pipe into KS and a
background from KL semileptonic decays.
The regeneration cross section of 110 MeV/c KL mesons was found to be 53 +-
17 mb in agreement with theoretical expectations. The angular distribution of
KS mesons after regeneration and the total cross section of KL for Be have been
measured.Comment: 14 pages, 8 figure
CPT violation in entangled B0-B0bar states and the demise of flavour tagging
We discuss the demise of flavour tagging due to the loss of the
particle-antiparticle identity of neutral B-mesons in the
Einstein-Podolsky-Rosen correlated states. Such a situation occurs in cases
where the CPT operator is ill-defined, as happens, for example, in quantum
gravity models with induced decoherence in the matter sector. The time
evolution of the perturbed B0-B0bar initial state, as produced in B-factories,
is sufficient to generate new two-body states. For flavour specific decays at
equal times, we discuss two definite tests of the two body entanglement: (i)
search for the would-be forbidden B0 B0 and B0bar B0bar states; (ii) deviations
from the indistinguishable probability between the permuted states B0bar B0 and
B0 B0bar.Comment: 12 pages LATEX, one eps figure incorporate
