where the catalyst is located. However, there are some limitations such as non-uniformity of growing conditions and difficult length control of CNTs. A few attempts were reported to attach CNTs......
in the presence of catalyst. The catalytic balls are lifted and remained continually on the tips of whiskers. But the diffraction peak of impurity has not been found in XRD (Fig.2).  ......

]. UZUNLAR et al [4] have studied the electroless copper deposition process on epoxy laminate substrates using a non- palladium catalyst, and without the use of the swell- and-etch process. TIAN... been widely used as a reducing agent for electroless nickel plating. Electroless copper plating process is more complicated than electroless nickel plating, as copper is not as good catalyst......
crystalline ZSM-5 as efficient catalyst for selective oxidation of toluene[J]. Materials Today Chemistry, 2017, 3: 37-48. [8] SIHAIB Z, PULEO F, GARCIA-VARGAS J M, et al.

C2-C8 NMHCs over the eastern mediterranean: seasonal variation and impact on regional oxidation chemistry[J]. Atmospheric......
of manufacturing cost and the demand for superior corrosion resistant materials result in the need for bimetallic systems. One example is the use of SS-Ti bimetallic joints in the spent fuel reprocessing unit of nuclear power plants. In these plants, boiling nitric acid carries the spent nuclear fuel from a titanium dissolver vessel through stainless steel pipes to other processing units [2-4......
