Abstract Modern computation based on von Neumann architecture is now a mature cutting-edge science. In the architecture, processing and memory units are implemented as separate blocks interchanging data intensively continuously. This transfer responsible for large part of power consumption. The next generation computer technology expected to solve problems at exascale with 10 18 calculations each second. Even though these future computers will be incredibly powerful, if they type...
Oxygen vacancies play crucial roles in determining the physical properties of metal oxides, representing important building blocks many scientific and technological fields due to their unique chemical, physical, electronic properties. However, oxygen are often invisible because dilute concentrations. Therefore, characterizing quantifying presence is utmost importance for understanding realizing functional oxide devices. This, however, oftentimes a non-trivial task. In this Perspective paper,...

First, main strategies for synthesis transfer are analyzed. initial section, particular attention devoted to use water‐soluble (Ca,Sr,Ba) 3 Al 2 O 6 as sacrificial layers, one most promising techniques fabrication membranes. The functionalities that have been observed then reviewed. doing so, authors begin by describing...
The anticonvulsant gabapentin has proven effective for neuropathic pain in three large placebo-controlled clinical trials. Experimental and studies have demonstrated antihyperalgesic effects models involving central neuronal sensitization. It been suggested that sensitization may play an important role postoperative pain. aim of the study was to investigate effect on morphine consumption patients undergoing radical mastectomy.In a randomized, double-blind, study, 70 received single dose oral...
The discovery of two-dimensional electron gases (2DEGs) in SrTiO3-based heterostructures provides new opportunities for nanoelectronics. Herein, we create a type oxide 2DEG by the epitaxial-strain-induced polarization at an otherwise nonpolar perovskite-type interface CaZrO3/SrTiO3. Remarkably, this heterointerface is atomically sharp, and exhibits high mobility exceeding 60,000 cm2V-1s-1 low temperatures. carrier density critical dependence on film thickness, good agreement with induced scheme.

Recently, new methods have developed that enable the realization ultrathin freestanding oxide films approaching limit. Oxides offer degrees freedom, due to strong electronic interactions, especially 3d orbital electrons, which give rise rich exotic phases. Inspired by this progress, platform for assembling thin with different...

Typically, flat, 2D topographies are assumed optimizing devices, which does reflect significant present in...
Segmentation of thermoelectric (TE) materials is a widely used solution to improve the efficiency generators over wide working temperature range. However, improvement can only be obtained with appropriate material selections. In this work, we provide an overview theoretical best performing unicouples designed from segmenting state‐of‐the‐art TE materials. The efficiencies are evaluated using 1D numerical model which includes all effects, heat conduction, Joule effects and dependent...
Abstract Symmetry‐imposed restrictions on the number of available pyroelectric and piezoelectric materials remain a major limitation as 22 out 32 crystallographic material classes exhibit neither pyroelectricity nor piezoelectricity. Yet, by breaking lattice symmetry it is possible to circumvent this limitation. Here, using unique technique for measuring transient currents upon rapid heating, direct experimental evidence provided that despite fact bulk SrTiO 3 not pyroelectric, (100) surface...
