Pulsed Lased Deposition of Single-Crystalline (001) Oriented Pb(Zr0.5T0.5)O3 Thin Film on PrScO3 Substrate

High quality thin films are important for domain engineering applications such as on-volatile memory applications. Single crystalline (001) oriented Pb (Zr0.5T0.5)O3 thin films have been grown by pulsed laser deposition on PrScO3 with strontium ruthenate (SRO) electrodes. Thin films were prepared from PZT ceramic targets with 15% excess PbO to compensate for lead loss at high deposition temperature. Layer by layer/step flow growth mode observed on AFM images has been realised by using a single terminated PrScO3 substrate as well as optimized deposition parameters. XRD measurements have confirmed the highly (001) oriented tetragonal symmetry. Furthermore, analysis conducted using piezoresponse force microscopy has shown that the thin films are monodomain with spontaneous ferroelectric polarization preferentially pointing upwards, i.e., away from the substrate. The absence of ferroelastic domains and the observed single ferroelectric domain structure are the results of both relatively small compressive misfit strain as well as favourable electrical boundary conditions.

Analisa Kenyamanan Kendaraan Angkut Massal dengan Pemodelan Pengemudi sebagai Sistem Multi-DOF

Kendaraan umum atau alat transportasi massal merupakan kendaraan yang sering digunakan oleh masyarakat Indonesia yang tidak memiliki kendaraan pribadi untuk bepergian. Masyarakat lebih menyukai menggunakan bus untuk melakukan perjalanan jauh karena waktunya lebih flexible dibandingkan kereta api. Supir bus menempuh perjalanan yang jauh sehingga mereka lelah. Hal ini dipengaruhi oleh tingkat Kenyamanan mengemudi. Kenyamanan dalam berkendara merupakan hal yang penting karena kelelahan yang dialami supir dapat menyebabkan terjadinya kecelakaan. Untuk mengatasi masalah ini maka akan dimodelkan dan disimulasikan dinamika kendaraan angkut massal (bus) dan pengemudinya. Untuk mengetahui respon dinamis (perpindahan, kecepatan, percepatan) yang dialami oleh supir. Secara garis besar penelitian ini akan dimodelkan dan disimulasikan dinamika kendaraan angkut massal (bus). Hasil simulasi berupa respon dinamis (perpindahan, kecepatan, percepatan) dari pengemudi bus dianalisa dan ditinjau dari standar Kenyamanan. Selain itu akan dianalisa mengenai frequency respon untuk mengetahui perbandingan input dan output yang diberikan pada kendaraan. Input yang diberikan berupa step dan harmonik.Dari penelitian ini didapatkan dari hasil simulasi time response bahwa pada amplitudo maksimum yaitu 0,03 m pada kecepatan 40 km/jam RMS percepatan hasil simulasi pengemudi pada bagian kepala sebesar 0,5398 m/s2, dada adalah 0,5431 m/s2, Perut adalah 0,5144 m/s2, dan pinggul adalah 0,5466 m/s2 yang menurut standar ISO 2631 berada pada kondisi sedikit tidak nyaman. Pada kecepatan 100 km/jam RMS percepatan yang dialami pengemudi pada bagian kepala sebesar 1,454 m/s2, dada adalah 1,447 m/s2, Perut adalah 1,074 m/s2, dan pinggul adalah 1,395 m/s2 menurut standar ISO 2631 berada pada kondisi sangat tidak nyaman

Hollow Fiber Bioreactor Technology for Tissue Engineering Applications

Hollow fiber bioreactors are the focus of scientific research aiming to mimic physiological vascular networks and engineer organs and tissues in vitro. The reason for this lies in the interesting features of this bioreactor type, including excellent mass transport properties. Indeed, hollow fiber bioreactors allow limitations to be overcome in nutrient transport by diffusion, which is often an obstacle to engineer sizable constructs in vitro. This work reviews the existing literature relevant to hollow fiber bioreactors in organ and tissue engineering applications. To this purpose, we first classify the hollow fiber bioreactors into 2 categories: cylindrical and rectangular. For each category, we summarize their main applications both at the tissue and at the organ level, focusing on experimental models and computational studies as predictive tools for designing innovative, dynamic culture systems. Finally, we discuss future perspectives on hollow fiber bioreactors as in vitro models for tissue and organ engineering applications. </jats:p

Apollo 14: Some geochemical aspects

Chemical analyses were obtained for five samples of Apollo 14 regolith fines, three 14230 core samples, soil clod 14049, breccias 14305 and 14319, 14310 basalt, and some separated phases. The chemical uniformity of these Apollo 14 samples indicates thorough mixing and/or uniform source rocks. Basalt 14310 can be matched well in composition by a four to one mixture of soil and plagioclase. The Eu(2+)/Eu(3+) ratios calculated for 14310 pigeonite and plagioclase are similar to those for Apollo 12 and 15 mare-type basalt phases; this indicates similar redox conditions. Apollo 14 samples are chemically similar to Apollo 12 and 15 KREEP as distinct from Apollo 11, 12, and 15 and Luna 16 mare-type basalts

Cellular automaton models for time-correlated random walks: derivation and analysis.

Many diffusion processes in nature and society were found to be anomalous, in the sense of being fundamentally different from conventional Brownian motion. An important example is the migration of biological cells, which exhibits non-trivial temporal decay of velocity autocorrelation functions. This means that the corresponding dynamics is characterized by memory effects that slowly decay in time. Motivated by this we construct non-Markovian lattice-gas cellular automata models for moving agents with memory. For this purpose the reorientation probabilities are derived from velocity autocorrelation functions that are given a priori; in that respect our approach is "data-driven". Particular examples we consider are velocity correlations that decay exponentially or as power laws, where the latter functions generate anomalous diffusion. The computational efficiency of cellular automata combined with our analytical results paves the way to explore the relevance of memory and anomalous diffusion for the dynamics of interacting cell populations, like confluent cell monolayers and cell clustering.The authors thank the Centre for Information Services and High Performance Computing (ZIH) at TU Dresden for providing an excellent infrastructure.
