carbon nanotubes are regarded as promising building blocks for the construction of novel biosensors due to their unique properties like fast electron transfer, high electrocatalytic effect and good biocompatibility. in the present study, the effect of different chemical oxidation’s methods of multi-walled carbon nanotubes (mwcnts) on the electrochemical behavior of modified graphite electrodes ...

the free vibration of the lattice cylindrical composite shell reinforced with carbon nano-tubes (cnts) was studied in this study. the theoretical formulations are based on the first-order shear deformation theory (fsdt) and then by enforcing the galerkin method, natural frequencies are obtained. in order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...

a novel modified ni-zsm-5 nanozeolite was fabricated via an organic template-free hydrothermal route. the average particle size of ni-zsm-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. then, carbon paste electrode (cpe) was modified by ni-zsm-5 nanozeolite and ni2+ ions were then incorporated to the nanozeolite matrix. electrochemical behavior of this electrode was ...

a thin film of epinephrine (ep) was electrochemically deposited on the surface of glassy carbon electrode previously activated in nahco3 solution. the cyclic voltammograms of the modified electrode indicate that the surface confined ep are strongly dependent on the solution ph, as expected for quinone/hydroquinone functionalities. the ep-modified glassy carbon electrode exhibited catalytic acti...

To overcome the problems of gene and drug delivery, nanotechnology has gained interest in recent years. Nanosystems with different compositions and biological properties have been extensively investigated for drug and gene delivery applications. Nanotechnology in drug delivery has been manifested into nanoparticles that can have unique properties both in vitro and in vivo, especially in targete...

Bu çalışmada çam kozalağının pirolizi ile elde edilen aktif karbon, sulu çözeltilerden Rodamin B boyasının gideriminde adsorban olarak kullanılmıştır. Üretilen karbon 4 farklı kimyasal katalizör (ZnCl2, H3PO4, H2SO4 ve KOH) modifiye edilerek, aktivasyon işleminin adsorpsiyon verimliliği üzerine etkisi incelenmiştir. Adsorpsiyon deneyleri kesikli sistemde çalışılmış baslangıç boya konsantrasyonu...
