The maximum torque values register an increase with the increase in loading of nickel in both composites and this is attributed to the non-interacting nature of nickel nanoparticles with rubber matrices. The cure time of natural rubber composites decreases with increase in the content of nickel, and in neoprene rubber cure, time increases with increase in filler content. In natural rubber, the curing reaction seems to be activated by the presence of nickel particles. The magnetization studies of the composites reveal that the magnetic properties of nickel are retained in the composite samples. The elastic modulus of natural rubber and neoprene rubber are largely improved by the incorporation of nickel particles.</p>10aCure characteristics10aElastic modulus10amagnetic properties10aNanocomposites1 aJamal, Muhammad, Abdul1 aJoy, Pattayil, Alias1 aKurian, Philip1 aAnantharaman, Maliemadom, R.  uhttps://library.ncl.res.in/content/magnetic-mechanical-and-rheological-properties-rubber-nickel-nanocomposites-001751nas a2200313   4500008004100000022001400041245006800055210006800123260000800191300001000199490000700209520080600216653002001022653002601042653003801068653002101106100002001127700001901147700001601166700001901182700002001201700001701221700002501238700002001263700002001283700001801303700001601321856010001337       2021                        eng d  a1580-294900aMechanical properties of anodic titanium dioxide nanostructures0 aMechanical properties of anodic titanium dioxide nanostructures  cJAN  a19-240 v553 a<p>Highly ordered and uniform titanium dioxide (TiO2) nanotubes (NTs) with different morphologies (15 nm, 50 nm and 100 nm in diameter) were prepared by the electrochemical anodization of Ti substrates. The TiO2 NTs' surface properties were characterized by X-ray diffraction (XRD) spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM). The elastic modulus (E) and the Vickers hardness (HV) of the Ti foil and of the different-morphology TiO2 NTs were evaluated with the nano-indentation technique. E and HV increase with the decreasing length/diameter of the NTs, meaning that NTs with smaller diameters are more resistant to mechanical wear. The elastic modulus of the TiO2 NTs with 15-nm and 50-nm diameters is similar to that of the human bone.</p>10aElastic modulus10amechanical properties10atitanium dioxide (TiO2) nanotubes10aVickers hardness1 aKulkarni, Mukta1 aSepitka, Josef1 aJunkar, Ita1 aBencina, Metka1 aRawat, Niharika1 aMazare, Anca1 aRode, Chandrashekhar1 aGokhale, Suresh1 aSchmuki, Patrik1 aDaniel, Matej1 aIglic, Ales  uhttps://library.ncl.res.in/content/mechanical-properties-anodic-titanium-dioxide-nanostructures
