This presentation of the subject includes an historical survey, the underlying theory of electrophoresis, dielectrophoresis, and the colloidal deposition of materials. This is followed by an assessment of the experimental equipment and procedures for electrophoretic and dielectrophoretic aggregation, manipulation, and deposition of nanoparticles, nanotubes, and other nanomaterials. Additional chapters explore the specific science and technology of electrophoretic film formation, using widely studied and application-driven nanomaterials, such as carbon nanotubes, luminescent nanocrystals, and nano-ceramics. The concluding chapters explore industrial applications and procedures associated with electrophoretic deposition of nanomaterials."

"This book analyses the state of the art of piezoelectric nanomaterials and introduces their applications in the biomedical field. Despite their impressive potentials, piezoelectric materials have not yet received significant attention for bio-applications. This book shows that the exploitation of piezoelectric nanoparticles in nanomedicine is possible and realistic, and their impressive physical properties can be useful for several applications, ranging from sensors and transducers for the detection of biomolecules to “sensible” substrates for tissue engineering or cell stimulation."

"ABSTRAKPada penelitian sebelumnya telah dilakukan penelitian mengenai lumpur pemboran yang mendapatkan kesimpulan bahwa lumpur berbahan dasar minyak merupakan fluida lumpur pemboran paling bagus, namun tidak direkomendasikan karena tidak berkelanjutan dan tidak ramah lingkungan. Untuk itu dilakukan penelitian at aditif yang dapat digunakan untuk lumpur berbahan dasar air, sehingga memiliki kualitas yang sama bahkan lebih baik dari lumpur berbahan dasar minyak. Penggunaan grafena sebagai zat aditif lumpur pemboran dapat memebentuk mud cake sebagai penghalang filtrasi dan penggunaan magnesium oksida MgO dapat meningkatakan nilai viscositas. Analisis rheologi dilakukan dengan metode bingham plastic sebagai metode yang sederhana dan pada umumnya dilakukan dilapangan migas dan penggunaan power law model dapat memberikan pemodelan yang lebih baik dari bingham plastic yang tidak dapat dilakukan untuk analisis dibawah permukaan sumur. Simulasi tension limit dilakukan untuk mengetahui batas aman kemampuan alat dalam menahan beban. Pengontrolan equivalent circulation density ECD sangat penting, jika ECD terlalu tinggi maka dapat menyebabkan loss circulation dan apabila terlalu rendah dapat menyebabkan gejala terjadinya semburan minyak atau kick. Pada bingham plastic, nilai plastic visosity dan yield strength aditif grafena mengalami peningkatan sebesar 25 dan 32 dibandingkan formula dasar base . Nilai yield strength MgO terlalu tinggi, mengindikasikan bahwa MgO tidak dapat digunakan sebagai zat aditif fluida lumpur pemboran. Pada aditif oksida grafena GO terjadi penurunan plastic viscosity 50 dan yield strength naik 180 . Nilai batas torsiaditif grafena meningkat 0,2 dan kedalaman pemboran bertambah 2,8 dibandingkan formula dasar base . Nilai batas torsi oksida grafena GO meningkat 0,2 dan kedalaman pemboran bertambah 2,08 dari formula base. Pada penetuan tension limit aditif grafena meningkat 38,8 dari formula dasar base dan pada oksida grafena GO menurun 2,11 dari formula dasar base . Dari simulasi equivalent circulation density ECD , grafena lebih cocok digunakan untuk sumur dengan tekanan formasi yang tinggi. Oksida grafena GO lebih cocok digunakan untuk sumur dengan tekanan formasi yang rendah.

ABSTRACT Previous research on drilling mud concludes that oil based mud is the best drilling fluid, but is not recommended because it is unsustainable and environmentally unfriendly. Therefore, research on additives that can be used for water based mud, so have the same quality even better than oil based mud. The use of graphene as a drilling mud additive may form mud cake as a filtration barrier and the use of magnesium oxide MgO may increase the viscosity value. Rheological analysis is done by Bingham Plastic Method as a simple method and generally done in oil and gas field and the use of power law model can provide better modeling of Bingham Plastic that can not be done for well under surface analysis. The tension limit simulation is performed to determine the safe limits of the tool 39 s ability to withstand loads. Control of equivalent circulation density ECD is very important, if ECD is too high it can cause loss circulation and if too low it can cause kick. In Bingham Plastic, the value of viscosity plastic and the yield strength of graphene additive increased by 25 and 32 compared to the base formula. The MgO yield strength value is too high, indicating that MgO can not be used as a drilling mud fluid additive additive. In graphene oxide additives GO there is a decrease in plastic viscosity 50 and yield strength up 180 . Graphene torque limit value increased 0.2 and drilling depth increased 2.8 compared to the base formula. The graphene oxide torque limit value GO increased 0.2 and drilling depth increased 2.08 from the base formula. At the tension limit of graphene additive increased 38.8 of the base formula and on the graphene oxide GO decreased 2.11 of the base formula. From the equivalent circulation density ECD simulation, grafena is more suitable for wells with high formation pressures. Graphene oxide GO is more suitable for low pressure wells. "

"Aligned Carbon Nanotube (ACNT) adalah salah satu jenis nanomaterial yang memiliki sifat luar biasa dan dapat digunakan untuk berbagai aplikasi di masa depan. LPG adalah salah satu sumber karbon yang dapat menghasilkan ACNT dengan metode Water Asssisted Chemical Vapour Deposition (WA-CVD). Penelitian ini mempelajari bagaimana kinerja dari substrat kuarsa dan bagaimana pengaruh suhu pertumbuhan dan waktu reaksi terhadap kualitas ACNT yang dihasilkan. Penelitian ini menghasilkan nanokarbon dengan yield yang cukup tinggi yaitu mencapai 2,70 mg/cm2. Hasil dari variasi waktu 100 menit dan 120 menit, didapatkan morfologi CNT yang dihasilkan pada waktu reaksi 100 menit lebih merata. Selanjutnya, uji pengaruh suhu terhadap hasil CNT menghasilkan produk pada suhu 800oC sebagai suhu optimum dimana yield dari nanokarbon adalah 2,22 mg/cm2 dan morfologi yang lebih merata dengan diameter 38 nm dilihat dari karakterisasi TEM, SEM-EDX, dan mapping. Sementara itu, keberadaan dari pengotor seperti karbon amorf dan CNT yang terenkapsulasi oleh katalis pada suhu 850oC didapatkan karena trade-off suhu tinggi dimana laju pelarutan karbon dalam katalis melebihi laju difusi dari karbon. Sedangkan sintesis dengan suhu 750oC hanya menghasilkan Carbon Nanofibers (CNF). Dengan hasil ini, dapat dikatakan bahwa orientasi dari CNT yang dihasilkan belum aligned atau dengan kata lain belum terbentuk ACNT. Meskipun demikian, orientasi dan morfologi paling merata didapatkan pada waktu reaksi 100 menit dengan 800oC. Perlakuan terhadap katalis menjadi suatu permasalahan belum didapatkannya ACNT. Selain itu, kinerja steam juga menjadi suatu masalah yang belum teratasi sehingga ACNT belum didapatkan. Waktu reaksi juga harus diturunkan untuk mendapatkan aligned dan penurunan waktu reaksi tidak akan jadi masalah untuk yield karena substrat kuarsa mampu menghasilkan yield yang tinggi.

Aligned Carbon Nanotube (ACNT) is a nanomaterial with extraordinary properties and has very wide future applications. LPG is one of carbon source to produce ACNT through Water Assisted Chemical Vapour Deposition (WA-CVD) method. This research investigates performance of quartz substrate and effects of growth temperature and reaction time on the quality of ACNT. The synthesis in this research produced nanocarbon with high yield reaching 2.70 mg/cm2. At the varied reaction time (100 and 120 minutes), morphology of ACNT produced at 100 minutes is more uniform. Afterwards, growth temperature effect shows that 800oC is the optimum where the yield is reaching 2.22 mg/cm2 and more uniform morphology with diameter 38 nm characterized by TEM, SEM-EDX, and mapping. However, existence of polluter such as amorphous carbon and encapsulated CNT by the catalyst was obtained as trade-off of high temperature at 850oC where dissolution rate of carbon to catalyst is higher than diffusion rate of carbon. Meanwhile, at 750oC only Carbon Nanofiber (CNF) can be produced. Therefore, this research could not produced aligned structured of CNT. Yet, good orientation and morphology of CNT were produced at 100 minutes synthesis and at 800oC. Catalyst pretreatment is one of root cause of not producing ACNT. Besides that, the performance of steam could be another source of the problem. Reaction time has to be reduced until below 100 minutes to get aligned carbon nanotube. The reduced reaction time could still produced high yield since quartz substrate could bear high yield of nanocarbons including ACNT."
