“…Because of the potentially explosive and toxic nature of diazomethane, this reaction must be performed using glassware without ground glass joints behind a safety shield in a fume hood! Diazomethane was prepared from Diazald® (De Boer and Backer, ) following a literature procedure (Diazald® and Diazomethane Generators. Sigma‐Aldrich Technical Bulletin AL‐180, 2007).…”

Diazomethane (CH(2)N(2)) was used to methylate the non-specific binding sites after molecularly imprinted polymer particles were prepared using methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the cross-linker and bisphenol A (BPA) as the template. After diazomethane treatment and subsequent removal of BPA by triethylamine, the treated molecularly imprinted polymer (TMIP) particles were tested for binding selectivity toward BPA and other organic compounds by capillary electrophoresis with ultraviolet detection. Even in the presence of compounds that were positively charged, neutral or negatively charged in the background electrolyte, BPA was selectively bound with the highest efficiency. A significant decrease in the affinity for metformin (MF, a positively charged compound), along with (13) C nuclear magnetic resonance spectra and electrophoretic mobility data, provided strong evidence for the elimination of non-specific -COOH binding sites in the TMIP particles. Only 8% of MF and 16% of diclofenac sodium salt (a negatively charged compound) remained as non-specific bindings because of hydrophobic interactions. Further comparison with poly(methyl methacrylate) revealed the true merits of the TMIP, which exhibited minimal non-specific bindings while preserving a high level of specific binding owing to molecular recognition.

“…For gamma-ray emission produced due to the interaction of CRs with molecular clouds of the CMZ, one would also expect to observe the spectral variations in the direction perpendicular to the Galactic Plane. In particular, de Boer et al (2017) claimed that there exists a change in the spectrum of the Galactic gammaray emission as a function of the latitude. They assumed that the gamma-ray emission produced by CR protons consists of two components.…”

We analyze the processes governing cosmic-ray (CR) penetration into molecular clouds and the resulting generation of gamma-ray emission. The density of CRs inside a cloud is depleted at lower energies due to the self-excited MHD turbulence. The depletion depends on the effective gas column density ("size") of the cloud. We consider two different environments where the depletion effect is expected to be observed. For the Central Molecular Zone, the expected range of CR energy depletion is E 10 GeV, leading to the depletion of gamma-ray flux below E γ ≈ 2 GeV. This effect can be important for the interpretation of the GeV gamma-ray excess in the Galactic Center, which has been revealed from the standard model of CR propagation (assuming the CR spectrum inside a cloud to be equal to the interstellar spectrum). Furthermore, recent observations of some local molecular clouds suggest the depletion of the gamma-ray emission, indicating possible self-modulation of the penetrating low-energy CRs.

In this article we present bosonic T-dualization in double space of the type II superstring theory in pure spinor formulation. We use the action with constant background fields obtained from the general case under some physically and mathematically justified assumptions. Unlike Ref.[1], where we used the first order theory, in this article fermionic momenta are integrated out. Full T-dualization in double space is represented as permutation of initial x µ and T-dual coordinates y µ . Demanding that T-dual transformation law of the T-dual double coordinate ⋆ Z M = (y µ , x µ ) is of the same form as for initial one Z M = (x µ , y µ ), we obtain the form of the T-dual background fields in terms of the initial ones. Advantage of using the action with integrated fermionic momenta is that it gives all T-dual background fields in terms of the initial ones. In the case of the first order theory [1] T-dual R-R field strength was obtained out of double space formalism under additional assumptions.
