“…In order to overcome the obstacle of scattering tissues, one possible method is performing the imaging within near-infrared (NIR) window (750-1100 nm), which is superior comparing with the ultraviolet-visible region. It can improve imaging quality vastly since it involves with the using of fluorophores emitting and the achieving of low levels of photon absorption [11][12][13][14][15][16].…”

Development of nanoparticles with multi-functionalities is of great importance. In this study, praseodymium sulfide (Pr 2 S 3 ) and molybdenum sulfide (MoS 2 ) nanoparticles were synthesized. The structural, morphological and optical properties of the as-obtained products were investigated by XRD, XPS, TEM, UV-vis-NIR spectroscopy, and photoluminescence spectroscopy. Pr 2 S 3 is found to be used in selective photodegradation of fluorescein sodium salt. MoS 2 can be utilized for selective photodegradation of rhodamine B. In the mixture of rhodamine B, fluorescein sodium salt and rhodamine 6 G, most of rhodamine B and part of fluorescein sodium salt are optically degraded by Pr 2 S 3 . In the mixture of rhodamine B, fluorescein sodium salt and rhodamine 6 G, part of fluorescein sodium salt and most of rhodamine B is degraded by MoS 2 . Moreover, they emit near-infrared fluorescence (800-1100 nm) when excited by the 785 nm light. Deep tissues imaging with highcontrast is shown, utilizing a nanoparticle-filled centrifuge tube covered with animal tissues (pig Bacon meat). Maximum imaging depth below the tissue surface of 1 cm is achieved. Our work provides a rapid yet efficient procedure to make nanoparticles for dual-application-potential in dyephotodegradation and near-infrared deep tissue imaging.

“…Figure 4C illustrates the XPS spectra of O 1s. As seen in Figure 4C, O1s spectra indicate peaks at 532.3, 533.7, and 537.6 eV which are connected to C–O, C–O–H, and C–O–C bonding 35,36 . The binding energy of peaks at 462.6 eV (3p 3/2 ) and 486.2 eV (3p 1/2 ) are attributed to Ru metal (Figure 4D).…”

Currently, a novel green material, defatted spent coffee ground (DSCG), is employed as a support to prepare DSCG supported Ru (DSCG‐Ru) material. DSCG and DSCG‐Ru materials are characterized by advanced surface analytical techniques such as N2 adsorption‐desorption, X‐ray diffraction, X‐ray photoelectron spectroscopy, and H2‐temperature‐programmed reduction. Characterization results revealed that DSCG‐Ru was prepared successfully. First, DSCG‐Ru is prepared at varying Ru contents on deoiled coffee waste and hydrogen production experiments are performed by the methanolysis of sodium borohydride on the DSCG‐Ru catalysts. It is observed that optimum conditions for the catalyst preparation are examined on the 10% Ru containing DSCG‐Ru catalysts and found as 10% Ru, 300°C, and 60 minutes. DSCG catalyst containing 10% Ru completed the methanolysis reaction in 1.5 minutes. Capacitive measurements to investigate the supercapacitor property of DSCG‐Ru catalysts prepared at optimum conditions 10% Ru, 300°C, and 60 minutes is investigated by cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge‐discharge measurements. Results revealed that gravimetric capacitance of the electrode at a current density is found as of 0.5 A/g and 43 F/g, greater than the literature values. DSCG‐Ru, green novel supported Ru catalyst, has a dual promising performance in hydrogen production and supercapacitor measurements.

“…The first group of peaks at about 530 eV can be associated with O in the frame of FeO [ 36 ]. The second peak-contribution group at about 531.2 eV can be attributed to the presence of C = O or –OH¯ groups [ 37 ]. The third group of peaks at about 532.4 eV is due to the presence of crystal-hydrated water in the composition of Na 2 B 4 O 7 · 10H 2 O [ 38 ].…”

Synthesis and Characterization of Nanocrystalline Boron-Nitride Thin Films by Ion Milling and Thermal Treatment for Tribological Coatings: An Approach to Quantifying the Growth Dynamic Process

et al. 2022

Hexagonal boron-nitride nanoparticle coating was deposited on AISI 1045 steel surface. The deposition process included a transformation of B-containing thin organic film into nanocrystalline BN using two methods: thermal annealing at 450–850 °C and reactive ion etching in Ar/N2 plasma. The film structure, phases, and film morphology of deposited nanoparticles of boron nitride on AISI 1045 steel were characterized by XPS, XRD, and EDS. Post-annealing at 450 °C does not lead to the formation of a BN phase in the layer. A non-stoichiometric BN phase with nitrogen deficiency appears at 650 °C. At 850 °C annealing, the formed BN phase is completely stoichiometric. The effects of deposited and incorporated BN on the friction and hardness properties of AISI 1045 steel were also studied. The post-annealing process improved the hardness from 5.35 to 11.4 GPa, showing a pronounced linear temperature dependence. An original approach was adopted to quantify the energy-dependent growth constants based on the indentation load-discharge curves measured on samples treated under different conditions. Those constants describe the rate of the reactions and the type of interdiffusion process characteristic for each material used. This approach can partially fulfill the role of the Rutherford backscattering spectrometry profile, which is an expensive and time-consuming process, mainly when light elements such as boron and nitrogen are used.
