ABSTRAK
Carbon nanotube (CNT) memiliki kemampuan untuk memfasilitasi transfer elektron sehingga dapat digunakan sebagai material biosensor yang potensial, khususnya biosensor generasi ketiga. Fabrikasi perangkat bioelektronik sistem transfer elektron langsung ini dilakukan dengan memodifikasi permukaan elektroda emas menggunakan self-assembled monolayer (SAM) dari sistiamina, single wall carbon nanotube (SWCNT) dan mikroperoksidase-11 (MP-11). Metode analisis voltametri siklik dan beberapa karakterisasi lainnya dilakukan untuk mengetahui keberhasilan modifikasi elektroda tersebut sekaligus mengetahui parameter penting dalam aplikasinya sebagai biosensor. Campuran asam kuat ...

Kebutuhan akan penggunaan carbon nanotube (CNT) dalam negeri terus meningkat setiap tahunnya. Sampai saat ini, produksi dan komersialisasi CNT terkendala pada proses yang mahal. Bahan baku CNT yang berpotensi karena harganya lebih murah adalah liquified petroleum gas (LPG). Untuk merealisasikan produksi CNT di Indonesia, diperlukan analisis tekno ekonomi produksi CNT dari LPG. Produksi CNT dilakukan dengan metode chemical vapor deposition (CVD) menggunakan katalis Fe-Co-Mo/MgO. Produksi dilakukan dalam reaktor fluidized bed yang dilengkapi cyclone untuk memisahkan ...

The present study focuses on the characterization of carbon nanotubes (CNTs) synthesized from flame under an atmospheric condition. A laminar flame burner was utilized to establish a rich premixed propane/air flame at the equivalence ratio ? = 1.8–2.2. The flame was impinged on a stainless steel wire mesh coated with nickel (Ni) catalyst to grow CNTs. Distribution and yield of the CNTs on the substrate were quantified. Carbon nanotubes formed on the substrate were harvested ...

Carbon Nanotubes-Titania (CNT-TiO2) composite that coated on diaper have been synthesized and tested for the removal of ammonia (self-cleaning test) and Candida albicans fungi (self-sterilizing test) that cause odor and make Candidiasis disease, respectively. The composite was characterized by FTIR, FESEM-EDX, XRD, and UV-Vis DRS. XRD and UV-Vis DRS results showed that the CNT-TiO2 composite has a high crystalline and low band gap. The results of self-cleaning and self-sterilizing tests showed that the optimum composition ...

The production of Carbon Nanotubes (CNT) has a problem with the limited results of Aligned CNT (ACNT) products, due the fact that an effective and economical method has not yet been discovered. This research used catalytic decomposition of methane with the Water-Assisted Chemical Vapor Deposition (WA-CVD) method by using a bench-scale plate structured catalyst reactor and a fixed bed reactor. The Fe-Ni/Al2O3 Catalyst prepared by sol-gel/dip-coating and Ni-Cu-Al Catalyst prepared by co-precipitation were used to ...

The potential of carbon nanotubes (CNTs) produced in our laboratory to be used for hydrogen storage was tested in this study. The test includes the determination of the hydrogen gas adsorption capacity and the dynamics of the adsorption and desorption of hydrogen on CNTs at isothermal temperature of 25oC and pressures of 0–1,000 psia. A similar test was also conducted on commercial CNTs obtained from the Chinese Academy of Sciences for comparison. The results showed ...

Aplikasi Carbon nanotube (CNT) dalam metode pengobatan kanker dapat dilakukan
karena menghasilkan selektivitas dan efektivitas targeting obat yang tinggi.
Fungsionalisasi CNT diperlukan untuk memperbaiki dispersibilitas, solubilitas, dan
toksisitas CNT. Fungsionalisasi dilakukan secara kovalen dengan oksidasi asam yang
terdiri dari campuran HNO3 dan H2SO4 dengan penambahan asam klorida (HCl).
Variasi yang dilakukan adalah konsentrasi HCl 6M, 8M, 10M, dan 12M pada suhu sonikasi
C. CP-f dikarakterisasi dengan uji dispersi, Fourier Infrared Transformation
Spectroscopy (FTIR), Thermal Gravimetry Analysis (TGA), UV-Vis Spectroscopy,
Electron Miscroscopy-Energy Dispersive Spectroscopy ...

The effect of metal doping on the hydrogen physisorption energy of a single walled carbon nanotube (SWCNT) is investigated. Unlike many previous studies that treated metal doping as an ionic or charged element, in this study, lithium and magnesium are doped to an SWCNT as a neutral charged by substituting boron on the SWCNT (Boron substituted SWCNT). Using ab initio electronic structure calculations, the interaction potential energies between hydrogen molecules and adsorbent materials were obtained. ...
