“…There are several methods for preparing metal nanoparticles such as pulsed laser deposition [16], flame metal combustion [17], chemical reduction [18], photo-reduction [19], electrochemical reduction [20], solvothermal [21], electrolysis [22], green method [23], microwave induced [24], sonoelectrochemical [25], aerosol flow reactor [26], photochemical reduction [27], chemical fluid deposition [28], spray pyrolysis [29,30], and spark discharge [31]. Among them, the pulsed laser ablation in liquids PLAL has become an increasingly popular top-down approach [32] for producing nanoparticles.…”

In this study we report the effect of laser parameters such as laser energy, laser wavelength as well as focusing condition of laser beam on the size and morphology of the gold nanoparticles (GNPs) prepared in deionised water by pulsed laser ablation. The optimum conditions at which gold nanoparticles obtained with controllable average size have been reported as these parameters affected the size, distribution and absorbance spectrum. Effect of energy was studied. The laser energy was divided into three regions (low, middle and high). A noteworthy change was observed at each region, as the average size changed from 5.9 nm at low energy to 14.4 nm at high energy and the gold nanoparticles reached a critical size of 8 nm at 100 mJ. The Effect of the wavelength on the particle size was examined at 1064 nm, 532 nm. It was found that, the optimum ablation laser wavelength was 1064 nm. Finally, significant results obtained when the effect of focusing conditions studied.

“…revealed the polysaccharide composition of the pumpkin. In summary, no significant difference in the shape and intensity of the absorption peak among the CWMs of pumpkin subjected to different treatments was observed, and only slight differences in types and degrees of methyesterification (DM) of pectin were detected.Bands at 830 cm −1 originate from the ring vibration of α-linkage between (1,4) galacturonic acid, the main unit of pectin skeleton(Szymanska-Chargot, Chylinska, Kruk, & Zdunek, 2015). The wave numbers at 2000-1000 cm −1 represented the vibrations of carbonyl esters and carboxylates, which are the main functional groups in pectin.…”

“…The region between 1,400 and 400 cm −1 , often called the "fingerprint" area, is widely used for the identification of compounds(Szymanska-Chargot & Zdunek, 2013). Absorptions at 1320 and 1,047 cm −1 are characteristic vibrations attached to cellulose, while bands at 1147 and 920 cm −1 could be assigned to hemicellulosic compounds(Szymanska-Chargot et al, 2015). These peaks proved the existence of cellulosic and hemicellulosic polysaccharides (e.g., xylan, mannan, and arabinogalactan).…”

High hydrostatic pressure (HHP) processing is a burgeoning nonthermal sterilization technology has been industrialized in foreign countries. The purpose of this research was to investigate HHP (100–600 MPa/2 min)‐induced texture and cell microstructural changes of fresh‐cut pumpkins compared with untreated and heated samples. Treatment efficacy was evaluated by texture profile analysis and combinational microscopy techniques, including transmission electron microscope (TEM) and confocal imaging. The results showed that the texture of pumpkin was jointly influenced by HHP‐triggered alterations in pectin characteristics, membrane completeness, and morphology of tissue. Samples subjected to HHP treatment could better maintain original histology properties than heated ones based on color parameter, hardness, relative electrical conductance, and degree of pectin esterification, among which moderate pressure (300–400 MPa) exerted more positive effects. Our findings provide theoretical guidance for the correlative application of HHP and promote further investigation on food varieties. Practical Applications HHP processing is a commercially implemented technology being used in vegetable‐based products. As an important factor highly correlated with freshness, texture alterations induced by processing are an industrial issue of great concern. This work provides new evidence on the softening mechanism comprehensively with respect to pectin, membrane, and morphology of tissue. The application of our current findings could be applied in other temperature‐sensitive food substrates and make it possible to produce products of high quality in mild temperature.

“…In recent years, Ni nanoparticles have proven significant potential in a wide range of applications such as battery manufacturing [2], textile industry [3], enhanced pseudo-capacitance [4] and catalyst [5]. There are several methods to synthesize nanoparticles such as electrochemical mechanical milling [6], solvothermal [7], electrolysis [8] and others [9][10][11]. Pulsed laser ablation in liquid (PLAL) is a promising technique due to its simplicity, require less sample preparation and free from contaminations [12][13].…”

Nickel nanoparticles exhibit superior ferromagnetic properties. This has attracted great interest due to its significant potential applications in various fields. The properties of nanomaterials are greatly affected by the environmental conditions during the synthetization process. In this work, nickel nanoparticles were synthesized by pulsed laser ablation in distilled water, ethylene glycol, chitosan, gum Arabic and walnut oil. For all samples, the ablated process was conducted for 5 minutes. The optical properties of colloidal nanoparticles were investigated by UV-Visible spectroscopy and Fourier Transform Infrared (FT-IR) spectrometer. Data from experimental works released that walnut oil has highest absorbance intensity which might be contributed to the existence of alkene functional group.
