In order to strengthen the recycling of waste plastics, improve the properties of recycled plastics and meet the great demand of oil in every field, waste plastics can be converted to diesel oil and lube base oil fraction through a number of steps, such as hydrocracking, isomerization and hydrodewaxing[1-3].
The diffractograms of the different catalysts was performed by comparison with the corresponding JCPDS cards.
The number of B-acid sites increased in Fe/H-ZSM-5 compared to Fe/ZSM-5, so the qualities of oil production were enhanced more with Fe/H-ZSM-5[12].
Besides, the number of B-acid sites increased in it.

It is well known that trivalent europium ion emits a characteristic red light with a number of narrow lines in the results of forbidden electric-dipole 4f→4f ( 5D0→7FJ) transitions.
The XRD data of Sr2B5O9Cl (Fig.1 (a)) was in good agreement with those of the JCPDS 27-0835 standard card.
Stretching frequencies of a coordinated BOn unites decrease as the coordination number n increases [2].

The dominant peak (2θ =31.71o) representing the (111) orientation is consistent with the standard data (JCPDS card number: 39-0354) with lattice constants, a = 0.4329 nm, b = 1.1192 nm and c = 0.3984 nm for orthorhombic-structured SnS [5,6,11].
Moreover, the substrate surface was entirely covered with nanoflakes, as a result increasing the number of nucleation sites.
As expected, illumination by higher power densities leads to more photon flux density, resulting in more number of electron-hole pairs generated [15,16].

A number of experimental studies can be found in the literature concerning particle stabilized emulsion and foams [2-4].
TEM image and XRD pattern (JCPDS-ICDD index card No.50-1089) for tetragonal structure) spherical synthesized ZrO2 nanoparticles by sol-gel method.
The results of IFT test for reference nanofluids with different concentration of ZrO2 indicates that nanoparticles reduces the IFT about 14 units in comparison to IFT of n-heptane/water that is calculated to be 51.4 at 23 ˚C (the number is in good agreement with literature numbers [9]).

In underdeveloped countries, higher outbreaks of bacterial infections from increased numbers of pathogenic strains increased antibiotic resistance and occasional bacterial mutations have caused serious health hazards, especially in the infant population [1].
Fig. 1 represents a surge in the number of peer-reviewed indexed articles over the years in Pubmed for nanostructures/therapeutic use as well as on bacteria.
Further, a small number of bacteria was taken out using a sterile rod and added to peptone water in a sterile test tube for ~2 h to allow bacterial growth which was visually observed through turbidity in the solution. 1.6.
In the case of UZ sample, the diffraction peaks from the pure ZnO sample may be indexed to the hexagonal phase of the zincite structure (JCPDS No. 1-1136), without any impurity peaks [31].
Hence, the peaks corresponding to 2θ values of 38.22ᴼ, 44.37ᴼ, and 64.57ᴼ may be assigned to both Au and Ag (marked by ¶ in Fig. 2 (a)) with miller indices (111), (200) and (220), respectively, for face centered cubic (FCC) structure of Au and Ag according to JCPDS card No. 65-2870 and JCPDS card No. 65-2871, respectively [32,33].

Table 1 shows the sample numbers and the conditions of silver electrodeposition.
X {200} = ( I {200} / I 0 {200} ) / Σ (I {hkl} / I 0 { hkl } ) (1) I {hkl} : measured intensity of {hkl} plane I 0 {hkl} : intensity of {hkl} plane in JCPDS card Results and discussion Relationship between Se concentration and {200} orientation ratio Fig. 1 shows XRD results for electrodeposited silver layers obtained under each set of conditions, and Fig. 2 shows the close relationship between the Se concentration of the silver plating solution and the {200} orientation ratio.
Because such an electrodeposited silver layer is well crystallized with highly ordered {200} planes normal to the direction of the electroplating plane, the number of grain boundaries allowing the diffusion of Cu during the heating test is reduced; thus, the electrical contact resistance of the surface after heating is improved.
In addition, the bend formability is improved because of both the increased ratio of the cube orientation, which has a positive effect on bend formability, and the reduced number of dislocations.

While numerous prior studies have concentrated on enhancing the thermal characteristics of PCMs by incorporating various nanomaterials in different mass fractions, a limited number have explored the potential of SiO2, TiO2, ZnO and CuO nanomaterials to enhance PCM performance.
FESEM images: (a) SiO2, (b) TiO2, (c) ZnO and (d) CuO Furthermore, Figure 2 presents X-ray diffraction (XRD) patterns for SiO2, TiO2, ZnO and CuO nanomaterials, which match well with the standard JCPDS card references (SiO2: 850335, TiO2: 29-1360, 21-1276, 21-1272, ZnO: 01-089-0511, 01-089-5898), verifying the identity of these materials as SiO2, TiO2, ZnO and CuO NPs from the JCPDS source.
