No full textInterview with Paul Selzer
No full textPaul Selzer, a computational chemist at Novartis (Basel, Switzerland), has been part of the computational medicinal chemistry field for over 20 years. Prior to joining Novartis in 1999, Selzer gained his PhD in computational chemistry from the University of Erlangen-Nuremberg (Erlangen, Germany) before working as a postdoctoral researcher. Selzer has authored a number of high-impact publications in the field and in this interview with Future Medicinal Chemistry, discusses some of the pressing issues in the computational medicinal chemistry arena, current work being conducted by the research group at Novartis, and more.

An investigation into the effect of particle platyness on the strength of granular materials using the discrete element method
No full textIt has long been recognised that the macroscopic mechanical behaviour of a granular material depends, to differing extents, on micro-mechanical properties such as the particle size distribution, the particle shape, the inter-particle friction angle and the particle strength. However, a systematic investigation of some of these effects is still lacking. In this paper we focus on particle shape, which is one of the fundamental characteristics of a granular material.
We build on previous work that used the axes of an equivalent scalene ellipsoid to characterise particle form, one of the three aspects that define particle shape. (The other two being angularity and roughness.) We use DEM simulations to investigate the effect of particle form, and in particular of particle platyness, on the friction angle of a granular material at critical state. It is found that a deviation of particle shape from that of a sphere leads to higher angles of friction; quantities such as fabric, average rates of particle rotation and interparticle sliding are used to provide insights into the underlying micromechanics

Organic Cocrystals of TCNQ and TCNB Based on an Orthocetamol Backbone Solved by Three-Dimensional Electron Diffraction
No full textWe report the first cocrystals of TCNQ and TCNB based on orthocetamol, a regioisomer of paracetamol. Through a simple solution growth process, cocrystals were produced containing orthocetamol as electron donors with coformers of either 7,7,8,8-tetracyanoquinodimethane (TCNQ) or 1,2,4,5-tetracyanobenzene (TCNB), as electron acceptors. Because of submicron crystalline domains, 3D electron diffraction was employed for structure solution in both systems. This revealed that both systems crystallize in a 1:1 stoichiometry in which orthocetamol forms a backbone allowing for linking of acceptor molecules in a mixed-stack configuration. Orthocetamol-TCNQ adopts an noncentrosymmetric Pc symmetry, and orthocetamol-TCNB a centrosymmetric P-1 symmetry. UV-vis and FT-IR were employed to probe the ability of these cocrystals to create charge transfer (CT) systems, revealing a low degree of charge transfer. Still, the possibility to use orthocetamol backbone as structural scaffold paves the way for an entirely new class of CT materials

A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
