Multiferroic materials have attracted world attraction due to their wide range of spintronic and data storage applications. Among multiferroic materials, bismuth iron oxide (BiFeO3) is a promising candidate as it offers advantages of high antiferromagnetic Neel temperature and high ferroelectric Curie temperature. An alternate to the conventional sol-gel method is proposed in the form of microwave exposure is proposed for the synthesis of nanoparticles. We here report structural, magnetic and dielectric properties of lanthanum doped bismuth iron oxide (Bi1-xLaxFeO3) nanoparticles with dopant concentration x as 0.3. Microwave power is varied as 180W, 450W and 810W. Microwave assisted nanoparticles are studied without any post treatment. Low microwave power results in amorphous nature of nanoparticles while transition to phase pure crystalline nanoparticles was observed at microwave power of 450W. High microwave power of 810W results in separation of bismuth deficient phase and BiFeO3 phase. Dielectric constant increases from 718 to 1095 as microwave power is increased from 180W to 450W. Transition from weak magnetic behavior to strong ferromagnetic behavior arises due to combined advantages of La doping and use of microwave power.

Pd is a unique substrate to explore graphene growth. Pd is a well-known “carbon sponge” which have potential to grow graphene with semiconducting properties in nature. Here, we reveal a solid phase reaction process to achieve Pd assisted graphene growth in nanoscale by in-situ transmission electron microscope (TEM). Significant structural transformation of amorphous carbon nanofiber (CNF) incorporated with Pd is observed with an applied potential in a two probe system. The Pd particle recrystallize and agglomerate starting from the middle part of CNF toward the end part of CNF with applied potential due to joule heating and large thermal gradient. Consequently, the amorphous carbon start crystallizing and forming sp2 hybridized carbon to form graphene sheet from the tip of Pd surface. The observed graphene formation in nanoscale by the in-situ TEM process can be significant to understand carbon atoms and Pd interaction.

The development of wireless energy transfer is critical to the promotion of implantable medical devices (IMDs). In this paper, an aluminum nitride (AlN) based piezoelectric micromachined ultrasonic transducer (pMUT) array is designed, fabricated and characterized, which can be a potential power supply for IMDs. The pMUT array is ideally suitable for integration with wireless-powered system since it is fabricated from miniaturized AlN membrane array of 4×4 units. Both the simulation and experiment are conducted to characterize the pMUT device. The transmitting sensitivity of the fabricated pMUT array is measured as 83 nm/V at a resonant frequency of 527 kHz.

Recent experimental efforts in investigating low-dimensional nanomaterials have spanned significantly beyond carbon nanotube (CNT) and graphene, which are often considered hallmarks of one- and two-dimensional (1&2D) nanostructures. Emerging layered nanomaterials, such as transition metal dichalcogenides (TMDC) and black phosphorus (P), have enabled new device functions and potential applications thanks to their intriguing material properties unavailable in CNT and graphene. In particular, nanoelectromechanical systems (NEMS) based on these new nanostructures exhibit new and interesting device properties. This paper describes the recent progresses in exploring and engineering atomically-thin semiconducting crystals into a new class of two-dimensional nanoelectromechanical systems, which hold promises for building novel nanoscale transducers. Exploration of resonant NEMS based on molybdenum disulfide (MoS2) reveals in these new nanoscale systems very broad dynamic range, rich nonlinear dynamics, and outstanding electrical tunability. Further, recent investigations show that black P NEMS offer the unique opportunity for harnessing the strong mechanical anisotropy in this nanocrystal composed of corrugated atomic sheets, demonstrating potential towards new device functions and applications that are unavailable to CNT and graphene based devices and systems.

We have investigated magnetic, electric and thermal response using an artificial magneto-electric multilayer. By the application of magnetic field, a capacitance and resistance value changed. This behavior was more likely due to magnetic coupling and tunneling effect. It is also revealed that the tunneling effect is responsible for thermal response. These results indicate a possibility of new type magneto-electric device.

Increasing power densities within microelectronic systems place an ever increasing demand on the thermal management. Thermal interface materials (TIMs) are used to fill air gaps at the interface between two materials, greatly increasing the thermal conductance when solid surface are attached together. The last decade has provided significant development on high-performing TIMs, and this paper makes a summarized review on recent progress on the topic. Current state of the art commercial TIM types are presented, and discussed in regards to their advantages and disadvantages. Two main categories of TIMs with high interest are then reviewed: continuous metal phase TIMs and carbon nanotube array TIMs.

In this article, we report C60 Fullerene Nano Cylindrical Tubes (FNCT). The FNCTs were synthesized by a liquid-liquid interface precipitation (LLIP) method using m-Xylene as a saturating solvent and TBA (Tetra butyl alcoholic) as precipitation agent leading to the formation of FNCTs with uniquely structured and well oriented size and shape. The experiment was conducted in a closed atmosphere maintaining a low temperature. The main advantage of these structures is that they are stable up to 5 months in normal room temperature. Characterizations were done to the FNCTs and concluded to have applications in the field of electronics. Enhanced semiconducting properties have been observed in the nanostructures which can be used in the application of solar cells, FET transistors, etc.

Cicada wings have nanostructures which shows superhydrophobic property, non reflecting to the light, and antibacterial characteristics. To mimic the nano structure of a cicada wing, we fabricated nano-pillar array using metal assisted etching. Fabricated nano-pillar array showed higher antibacterial property for E. coli. Our introduced process has advantages for industrial usage because of low cost and low environmental load based on wet process.
