Xia et. al and Yang et. al reported that the pores were capable of adsorbing and releasing drug [9, 10], therefore porous bioceramics had been used as a drug delivery system for delivery of anti-tumor agents and antibodies in the treatment of osteomyelitis [11].
Palazzo et. al and Kim et. al confirmed that lower porosity of HA showed more significant initial burst release due to the tendency of the drug molecules to loosely bound and concentrated on the external macropore walls rather than internal pores [15, 16].
Zhang et. al had synthesized CHA assisted by polyethylene glycol (PEG).
Juang et. al had demonstrated that the HA particle size will only increase if the calcination temperature is more than 700°C [18].

El Miri et al. developed the starch based film reinforced with CNF demonstrated the good optical transparency, reduced water vapor permeability (WVP), and enhanced tensile properties, greatly satisfying the general requirements of packaging applications [6].
Hamid et al. (2019) showed that the addition of active and hydrophobic compounds of α-tocopherol (0.4 w/w) not only gives the protective effect in food, but also improves the mechanical and barrier properties in the development of biodegradable films.
The opacity of the film was adapted by Harini et al., 2018 [10] Statistical Analysis.
Hamid et al. (2018), SRC based films dissolved almost completely due to the hydrophilic nature of carrageenan, however solubility improves with additional of 0.4%w/w Tp [7].
Similar results was in agreement with Nouri et al. (2018) where the addition of Rosmarinus officinalis L. extract leading to form a heterogeneous oil droplet surface in κ-carrageenan/nanoclay nanocomposite film.

For instance, it was found by Jojibabu et al. [24] that the LSS of the aluminium joints increased by 53%, 49% and 46% with adding 1 wt.% CNT, 0.5 wt.% GNP and 0.5 wt.% single-walled carbon Nano horns (CNH), respectively.
However, Moriche et al. [30] found that incorporating of GNPs into the epoxy had no effect on the lap-shear strength results of adhesive-copper and adhesive-aluminium joints, which was due to a weak interface reinforcement-matrix.

Wu et al. [4] studied numerically the effect of an oblique plate on the improvement of heat transfer in mixed convection.
Young et al. [6] have made a numerical investigation of the forced convection in a compressible fluid in a channel containing a row of heated obstacles and attached to its lower wall.
On the other hand Huminic et al. [15] studied entropy generation macrochannel and entropy generation in cavities.
Also Alsarraf et al. [16] studied numerically the effect of four constant temperature pipes on natural cooling of electronic heat sink of aluminum/water nano-fluid.

Et al. studied overlayer formation and miscibility of Sn on Pt (111) by a mixed embedded atom potential and Morse potential.
Creemers et al. first use Pt-Sn modified embedded atom method (MEAM) to study segregation and ordering, however they did not fit the alloying parameters.
Sung et al prepared bimetallic nanoparticles of Pt and Sn with an ion exchange3, they showed that the microstructure of the Pt-Sn nanoparticles seems to be Pt core covered with Sn.
Ravelo et al. developed Sn’s MEAM parameters based on reference structures of diamond and FCC [21-22].

Wu et al. reported a kind of new hierarchical, which the ZnO micro/nano structure film constructed on metal Zn foil surface.
Monika et al. synthesized flower-like ZnO nanostructure based electrochemical DNA biosensor for bacterial meningitis detection [16] However, further practical application of these ZnO nanomaterials is restricted by wide bandgap due to the UV light was always required in the photocatalysis [17].
Xiang et al. reported a visible light responsive MgO/ZnO/In2O3 mixed-metal oxide (MZI-MMO) heterostructure photocatalyst for methylene blue degradation [21].
Ranjith et al. reported the synthesis of Al and Cu doped ZnO thin films and the visible light photocatalytic degradation of methylene blue [23].

Tafel diagrams for the cathodic and the anodic current density for a = 0.25 and j0 = 10-4 A cm-2 (after Koryta et al. [4]).
Recently, Açikyildiz et al. [3] reported that micropores are not useful because electrochemical reactions for charge balance require ionic conductance media, and the mass transport rate of ionic species into micropores on the surface of the electrode material becomes several orders of magnitude lower in comparison with that in the bulk of the electrolyte.
Fig. 3 presents the exemplary transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) images of the Pt octahedral and tetrahedral nanoparticles on supported carbon black obtained by Liu et al. [40].

More recently,
however, Yagi et al. [2] have updated this

as now more data especially of Zr-based bulk
glasses do not fall inside the former "main" data
band but show distinctly higher peak temperatures
like Cu-Zr (range C in Fig. 1), and are thus interPeak

The addition of Al to this alloy reduces the stability of the quasicrystals [12] and increases the peak temperature in Fig. 3 at the same time, and also the thermal stability of the quasicrystals in Zr69.5Cu12Ni11Al7.5 is comparatively much smaller [11, 17].
If small frequency factors like 10 10 to 10 12 s-1 for Zr-Cu-Al(-Si) [1] are real, however, we have to understand the fact that they are not found in general but only in special cases (we mostly find 10 12 to 10 13 s-1 in our amorphous and quasicrystalline alloys).
Khonik (Voronezh) for their kindness of supplying the melt-spun Zr-Ti-Nb-Cu-Ni(-Al) and Zr-Ti-Cu-Ni-Al ribbons, respectively, and to I.S.
