Food Physical Chemistry and Biophysical Chemistry

Food Physical Chemistry is considered to be a branch of Food Chemistry^1,2^ concerned with the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the applications of physical/chemical techniques and instrumentation for the study of foods^3,4,5,6^. This field encompasses the "physiochemical principles of the reactions and conversions that occur during the manufacture, handling, and storage of foods"^7^. Two rapidly growing, related areas are Food Biotechnology and Food Biophysical Chemistry.

Revealing three-dimensional structure of individual colloidal crystal grain by coherent x-ray diffractive imaging

We present results of a coherent x-ray diffractive imaging experiment performed on a single colloidal crystal grain. The full three-dimensional (3D) reciprocal space map measured by an azimuthal rotational scan contained several orders of Bragg reflections together with the coherent interference signal between them. Applying the iterative phase retrieval approach, the 3D structure of the crystal grain was reconstructed and positions of individual colloidal particles were resolved. As a result, an exact stacking sequence of hexagonal close-packed layers including planar and linear defects were identified.Comment: 8 pages, 5 figure

The 24th IUPAC International Conference on Physical Organic Chemistry (ICPOC 24)

The IUPAC sponsored biennial Conference on Physical Organic Chemistry (ICPOC) series bear a long history and a solid reputation as the leading international gatherings on Physical Organic Chemistry. Since their first installment in Crans sur Sierre (Switzerland) in 1972, ICPOC meetings have been held in Noordwijkerhout (The Netherlands, 1974), Montpellier (France, 1976), York (UK, 1978), Santa Cruz (USA, 1980) Louvain-la-Neuve (Belgium, 1982), Auckland (New Zealand, 1984); Tokyo (Japan, 1986), Regensburg (Germany, 1988), Haifa (Israel, 1990), Padua (Italy, 1994), Incheon (Korea, 1996), Florianopolis (Brazil, 1998), Göteborg (Sweden, 2000), San Diego (USA, 2002), Shanghai (China, 2004), Warsaw (Poland, 2006), Santiago de Compostela (Spain, 2008), Busan (Korea, 2010), Durham (UK, 2012), Ottawa (Canada, 2014), Sidney (Australia, 2016). The 24st IUPAC International Conference on Physical Organic Chemistry (ICPOC 24) was held at the University of Algarve, in Faro, Portugal, July 1–6, 2018.info:eu-repo/semantics/publishedVersio

Physical properties and crystal chemistry of Ce2Ga12Pt

Single crystals of the new ternary compound Ce2Ga12Pt were prepared by the self-flux technique. The crystal structure with the space group P4/nbm was established from single-crystal X-ray diffraction data and presents a derivative of the LaGa6Ni0.6 prototype. Magnetic susceptibility measurements show Curie-Weiss behaviour due to local Ce^3+ moments. At high temperatures, the magnetic anisotropy is dominated by the crystal-electric-field (CEF) effect with the easy axis along the crystallographic c direction. Ce2Ga12Pt undergoes two antiferromagnetic phase transitions at T_N,1 = 7.3K and T_N,2 = 5.5K and presents several metamagnetic transitions for the magnetic field along c. Specific-heat measurements prove the bulk nature of these magnetic transitions and reveal a doublet CEF ground state. The 4f contribution to the resistivity shows a broad maximum at T_max ~ 85K due to Kondo scattering off the CEF ground state and excited levels.Comment: 12 pages, accepted in J. Phys.: Condens.

Nanoassembly of Polydisperse Photonic Crystals Based on Binary and Ternary Polymer Opal Alloys

Ordered binary and ternary photonic crystals, composed of different sized polymer-composite spheres with diameter ratios up to 120%, are generated using bending induced oscillatory shearing (BIOS). This viscoelastic system creates polydisperse equilibrium structures, producing mixed opaline colored films with greatly reduced requirements for particle monodispersity, and very different sphere size ratios, compared to other methods of nano-assembly
