"Paduan TiNi merupakan paduan ingat bentuk yang dicirikan oleh adanya transformasi fasa reversibel. Dalam penelitian ini dilakukan pengamatan karakteristik presipitat TiNi3 sebagai akibat perlakuan panas penuaan pada paduan Ti-50.04%at.Ni, dengan tujuan untuk dapat mempelajari perilaku presipitat TiNi^ dan pengaruhnya terhadap temperatur transformasi fasa. Pengamatan struktur presipitat dilakukan dengan menggunakan metoda mikroskop elektron transmisi TEM dan temperatur transformasi diamati dengan menggunakan metoda resistivitas \istrik four point probe. Hasil pengamatan menunjukan bahwa presipitat TiNii tumbuh membesar mengikuti penambalian waktu penuaan dengan orientasi pertumbuhannya adalah ....- Pertumbuhan presipitat tersebut tidak menimbulkan perubahan yang signifikan terhadap temperatur transformasi.

TiNi alloy represents the shape memory alloy which is characterized by reversible phase transformation. In this investigation observation of characteristic TiNi? precipitation of a Ti-50.04%at.Ni alloy affected of aging treatment was carried out. The research was intended to study the influence of TiNi3 precipitate against the phase transformation temperature. The structure precipitate was observed by transmission electron microscope (TEM) and the transformation temperatures measured by four-point probe electrical resistant method. Experimental results showed that TiNi:, precipitates grow up with aging time increased- The orientation of precipitate growth relatively to matrix was found lying on ..... This precipitate growth did not significantly affect the transformation temperature."

"ABSTRAKScaffold membran kitosan dan kitosan-RGD cangkang kepiting diproduksi oleh BATAN, untuk rekayasa jaringan pada rongga mulut. Sifat arsitektural kedua scaffold belum diteliti. Tujuan: Meneliti sifat arsitektural scaffold membran kitosan dan kitosan-RGD cangkang kepiting. Metode: Jumlah, ukuran, jarak antar pori dan porusitas dengan uji SEM dan analisis ImageJ. Daya serap dengan Swelling test. Hasil: Scaffold kitosan dan kitosan-RGD memiliki 225 dan 237 buah pori, berukuran 176.4mm dan 178.3mm, porusitas sebesar 12.8 dan 12.9 , jarak antar pori sebesar 94.7mm dan 93.3mm, serta daya serap sebesar 10.5mgH2O/mgScaffold dan 19.2mgH2O/mgScaffold. Kesimpulan: Sifat arsitektural scaffold membran kitosan RGD cangkang kepiting cenderung lebih baik.

ABSTRAKIntroduction Crab Shell Chitosan and Chitosan RGD membrane Scaffolds have been made by BATAN, for tissue engineering in oral cavity. Architectural properties of both scaffolds have never been analyzed. Purpose To analyze the architectural properties of both scaffolds. Methods Pore amount, pore size, interpore distance and porosity using SEM test with ImageJ analysis. Water absorption using swelling test. Results Chitosan and Chitosan RGD scaffolds have 225 and 237 pores, 176.4mm and 178.3mm sized pore, porosity of 12.8 and 12.9 , interpore distance of 94.7mm and 93.3mm, with water absorption of 10.5mgH2O mgScaffold dan 19.2mgH2O mgScaffold. Conclusions Crab shell chitosan RGD membrane scaffold has better architectural properties. "

"This book presents the recent advances that have been made using mathematical methods to resolve problems in microscopy. With improvements in hardware-based aberration software significantly expanding the nanoscale imaging capabilities of scanning transmission electron microscopes (STEM), these mathematical models can replace some labor intensive procedures used to operate and maintain STEMs. This book, will also cover such relevant concepts as superresolution techniques, special denoising methods, application of mathematical/statistical learning theory, and compressed sensing."
