Layered CoO2 is of great interest for its promising properties but is meta‐stable in its bulk form. CoO2 is synthesized by converting the quasi‐1D crystal structure of bulk Ca3Co2O6 via a hydrothermal treatment. The resulting nanostructures are predominantly nanoscrolls with very thin walls, which exhibit long‐term stability. A detailed structural investigation reveals that the CoO2 is found to crystallize in monoclinic form, similar to the related CaCoO2‐CoO2 misfit structure. Individual nanoscrolls are characterized electrically and show a p‐type semiconducting nature with a high current‐carrying capacity of 4·105 A cm−2 and an extremely high breakdown voltage of up to 270 kV cm−1. The results demonstrate the possibility to stabilize meta‐stable materials in low‐dimensional forms and a promising application of the nanoscrolls as interconnect in high‐voltage electronic circuitry.

One-dimensional (1D) nanomaterials have received a lot of attention owing to their unique structural, electrical, and optoelectrical properties. Perovskite-structured lanthanum chromite (LaCrO3, LCO) is a well-known semiconducting material that is used as an active component or interconnect in nanoelectronics, electrochemical and optoelectronic devices. The 1D LCO nanorods are expected to show better electrical transport characteristics due to dimensional confinement in addition to the ease of integration in devices. The conventional synthetic protocols typically yield 3D nanoparticles with irregular morphologies limiting the scope of this important material. Herein, we report a template-free molten salt synthesis (MSS) method to synthesise single-crystalline 1D nanorods of LCO. The strategy was further extended to synthesise Sr2+-doped La1−xSrxCrO3 (LSCO-10 where x = 0.1; and LSCO-20 where x = 0.2) nanorods as alkaline earth metal doping is known to enhance electrical properties. The electrical conductivity was found to be 27 mS cm−1 for pure LCO nanorods, which further increased on Sr2+ doping to 12 640 mS cm−1 (LSCO-10) and 22 700 mS cm−1 (LSCO-20). The observed conductivity values are about three orders higher than those of previous reports for LCO nanoparticles with various morphologies. This work establishes the template-free MSS as a new route to access low dimensional morphologies with superior performance, which were otherwise inaccessible. [ABSTRACT FROM AUTHOR]

Microwave irradiation of metals generates electric discharges (arcs). These arcs are used to generate nanoparticles of Cu and Ni and one-dimensional nanorods of CuS, ZnF2, and NiF2 protected with fluorinated amorphous carbon. We have also synthesized reduced graphene oxide and partially rolled graphene by this method.

The act of multiplying includes adding partial products repeatedly, and conventional multipliers call for many adders to perform partial product addition in higher order multiplication. A multiplier’s effectiveness and efficiency are evaluated using parameters such as speed, time delay, area, Power Delay Product (PDP), accuracy, and power consumption. In order to choose the optimum multiplier, this project is to evaluate various multipliers their performance metrics. Then, suggests employing a hybrid technology-based adder to improve the performance of the selected multiplier. The power consumption of the multiplier can be significantly reduced while maintaining the required accuracy by using a hybrid technology-based adder and low power full adders. This will allow multipliers to be used in low-power applications where power consumption is a major concern. To summarize, the goal of this project is to design and compare different multipliers using H-spice coding, as well as to improve the performance of the chosen. This project used 4x4 multiplier evaluation using 32nm technology.

Compression therapy for the treatment of venous leg ulcers (VLUs) is often inconsistent due to variable practitioner competencies, patient pain tolerance and anatomy, as well as challenges adapting to varying material properties of the compression products used. A multi-point wireless pressure sensor (MPS) that longitudinally monitors pressure underneath a bandage provides a new means for surveillance of sub-bandage pressures. The MPS was used to measure sub-bandage pressure during and after the application of two-layer compression bandages on healthy volunteers. Live digital guidance improved the targeting of pre-specified sub-bandage pressures, from 31% using the manufacturer's visual tension indicator to 85.7% when using digital guidance from an MPS positioned on the lateral side of the lower leg. Varying foot position during bandage application did not lead to a significant change in resting sub-bandage pressures. Regional variations in subbandage pressure were observed at different sensor locations, and a 23.5% mean decrease in static resting pressure was noted across all sensors 4 hours after the initial bandage application, with a steady state resting pressure reached after 90 minutes of wear time. The use of the MPS during and after bandage application offers real-time feedback that can facilitate interventions to improve the delivery of compression therapy. [ABSTRACT FROM AUTHOR]
