  1. Pressurizing the mixtures of two ionic liquids: Crystallization versus vetrification

    F. Capitani, F. Trequattrini, O. Palumbo, P. Roy, P. Postorino and A. Paolone

    Pure TMPA-TFSI and the mixture (TMPA-TFSI)100–x (TMHA-TFSI)x with x =2 crystallize upon compression at a pressure below 1 GPa.

    The mixtures with x = 7, 15 and 50 do not crystallize, but rather transform into a glass state when a pressure between 1 and 2 GPa is applied.

    On increasing pressure, the concentration of the cis-TFSI increases, as it has a lower volume compared to trans-TFSI.

  2. Aligned diphenylalanine nanotube–silver nanoparticle templates for high-sensitivity surface-enhanced Raman scattering

    Aligned FF-PNTs facilitate a dense packing arrangement of plasmon-active Ag nanoparticles, creating “hot spots” that enable picomolar and femtomolar probe molecule concentrations to be probed, with demonstrated blinking in surface-enhanced Raman scattering signal, indicative of single-molecule detection. The template is stable under high laser illumination with a power density of ~6.25 MW/cm2 in comparison to only silver nanoparticles.

  3. Vibrational properties of layered BiTeCl single crystal

    We observe and assign Raman modes of bulk BiTeCl and exfoliated flakes. The lowest wavenumber rigid layer in-plane vibrational mode E32 at 319 cm−1 is insensitive to laser power and temperature, similar to shear modes of two-dimensional materials. Using multiple lasers of 488, 514.5, 647, and 785 nm, 2 in-plane E modes are more pronounced for low-energy lasers whereas 2 out-of-plane A1 modes behave inversely, which could be related to interband transitions.

  4. An easy approach to reveal the metallic nature of graphene by Breit–Wigner–Fano lineshapes using Raman spectroscopy

    This work aims to report the detailed investigation of the asymmetry lineshapes in Raman spectra due to metal doping. By systematically focus on the asymmetry region, we have established that this asymmetric linewidth broadening is due to the Fano interaction of continuum with discrete phonon mode. In addition, using BWF lineshapes, which are considered as the ‘hallmark’ of metallic nature of SWCNT, a simple methodology is proposed to unveil the metallic nature of graphene.

  5. Raman spectroscopy as a novel method in placental research: Recognizing the pattern of placental hypoxia

    Natalia Schlabritz-Loutsevitch, Kushal Gandhi, Fatimah Soydemir, Paul Brownbill, Raghvendra Sengar, Gary Ventolini, Paul Bruillard and Luke Gosink

    Raman spectroscopy (RS) is a nonelastic photon scattering technique. We evaluated whether a specific RS pattern exists in fetal venous perfusates obtained at 30-min intervals from the ex vivo human dual placental perfusion model under hypoxic (n = 6) and normoxic (n = 5) conditions, a stratified principle component and a linear support vector machine analyses showed that the separation between two conditions was readily feasible at 60–120 min of perfusion; after this, any apparent differences were most likely the result of artifact overfitting.
