“…In our works 7,8 we have shown that a copper-vapor laser can also be used for such experiments. This laser generates pulses of emission with wavelengths 510.6 and 578.2 nm, of duration ~20 ns, frequency repetition ~10 4 Hz, average power 1-10 W and peak power 10 4 -10 5 W. Typical experimental scheme using a copper vapor laser is shown in Figure 2.…”

“…Raman spectra of hydrocarbon and fluorocarbon zigzag structure molecules have been studied. The investigations have been fulfilled for following substances: C n H 2n+2 (n=6, 7, 10), C n F 2n+1 Br (n=6,7,8, 10, 14), C n F 2n+2 , C n H 2n O 2 (n=4, 5, 8, 10, 11, 13, 15, 18).

Spectroscopic method of zigzag chain molecules length determination from Raman spectra was developed. The method is based on measuring Raman lines frequencies, corresponding to acoustical modes and different optical modes of chain molecules. The excitation of Raman spectra was produced by continuous argon laser or by pulsed radiation from copper vapor laser. Raman spectra of hydrocarbon and fluorocarbon zigzag structure molecules have been studied. The investigations have been fulfilled for following substances: C n H 2n+2 (n=6, 7, 10), C n F 2n+1 Br (n=6,7,8, 10, 14), C n F 2n+2 , C n H 2n O 2 (n=4, 5, 8, 10, 11, 13, 15, 18). The frequency dependence of some Raman modes on the length of zigzag molecule has been observed. The theory, explaining this dependence, is developed. The obtained results allow estimating fluorocarbon and hydrocarbon molecules length from the Raman spectra parameters.

“…The spectra of both molecules are very similar due to the chemical similarity between the decane and the hydrophobic part of the DOPC molecules. For example, the Raman peak at 1440 cm À1 , corresponding to the scissor-type bending mode of the methylene group, is present in both DOPC [12] and decane [13] spectra. In contrast to this, the Raman line at 1650 cm À1 , corresponding to the C¼C double-bond stretching, is only present in DOPC [14].…”

Microfluidic jetting is a promising method to produce giant unilamellar phospholipid vesicles for mimicking living cells in biomedical studies. We have investigated the chemical composition of membranes of vesicles prepared using this approach by means of Raman scattering spectroscopy. The membranes of all jetted vesicles are found to contain residuals of the organic solvent decane used in the preparation of the initial planar membrane. The decane inclusions are randomly distributed over the vesicle surface area and vary in thickness from a few to several tens of nanometers. Our findings point out that the membrane properties of jetted vesicles may differ considerably from those of vesicles prepared by other methods and from those of living cells.

A new technique, that involves the plasma processing of frozen hydrocarbons by a pulsed laser generated graphitic plasma, is presented. Polymer‐like hydrogenated amorphous carbon (a‐C:H) thin films were created by allowing the plasma generated during the fs‐pulsed laser ablation of a highly oriented pyrolytic graphite target in high vacuum, to impact on solid layers of n‐hexane (CH3(CH2)4CH3) at 77 K. This technique results in the formation of thin films whose morphology and properties are shown to depend on the plasma processing time tp. Polymer‐like a‐C:H with residual hexane incorporated into the carbon matrix and exhibiting a unique dendritic surface morphology was formed after short processing times. Following longer processing times, these dendritic structures are destroyed resulting in thin films having similar spectral properties to those of conventional a‐C:H. The composition of the plasma was studied using time of flight mass spectrometer (TOF‐MS) and the surface morphology of the synthesized thin films was examined by atomic force microscopy (AFM). A variety of analytic techniques including photoluminescence (PS), UV–Vis absorption, surface enhanced Raman (SERS), and Fourier transform infrared (FTIR) spectroscopy have been used to characterize the structure and composition of these materials.
