Unipolar and bipolar switching for power electronics control were compared regarding current ripple and power losses. Here, unipolar switch...


Ultra-Compliant Heterogeneous Copper-Tin Nanowire Arrays Making A Super-Solder.

Due to the substantial increase in power density, thermal interface resistance that can constitute more than 50 % of the total thermal resistance has generally become a bottleneck for thermal management in electronics. However, conventional thermal interface materials (TIMs) such as solder, epoxy, gel, and grease cannot fulfill the requirements of electronics for high-power and long-term operation. Here we demonstrate a high-performance TIM consisting of a heterogeneous copper-tin nanowire array which we te...

DNA-Based Single-Molecule Electronics: From Concept to Function.

Beyond being the repository of genetic information, DNA is playing an increasingly important role as a building block for molecular electronics. Its inherent structural and molecular recognition properties render it a leading candidate for molecular electronics applications. The structural stability, diversity and programmability of DNA provide overwhelming freedom for the design and fabrication of molecular-scale devices. In the past two decades DNA has therefore attracted inordinate amounts of attention i...


ns Pulsed Electric Field-Induced Action Potentials in the Circuital Model of an Axon.

Pulsed electric fields with duration in the sub- and ns time scale (nsPEFs) increase the permeability of cell membranes, enabling the transport of normally impermeant molecules into or out of the cell (electroporation). Such effect is associated to intracellular alterations and indicates nsPEFs as a new stimulus to modulate cell functions. In particular, studies dealing with the application of nsPEFs to excitable cells suggest their use for the stimulation/inhibition of cell excitation. In this paper, the c...

Mesh electronics: a new paradigm for tissue-like brain probes.

Existing implantable neurotechnologies for understanding the brain and treating neurological diseases have intrinsic properties that have limited their capability to achieve chronically-stable brain interfaces with single-neuron spatiotemporal resolution. These limitations reflect what has been dichotomy between the structure and mechanical properties of living brain tissue and non-living neural probes. To bridge the gap between neural and electronic networks, we have introduced the new concept of mesh elec...

Herein, coin cell-type Al-air batteries using cost-effective and eco-friendly chitosan hydrogel membranes modified by SiO2, SnO2, and ZnO have been prepared and assembled. The Al-air coin cell employing chitosan hydrogel membrane containing 10 wt.% SiO2 as ...

Toward Wearable Self-Charging Power Systems: The Integration of Energy-Harvesting and Storage Devices.

One major challenge for wearable electronics is that the state-of-the-art batteries are inadequate to provide sufficient energy for long-term operations, leading to inconvenient battery replacement or frequent recharging. Other than the pursuit of high energy density of secondary batteries, an alternative approach recently drawing intensive attention from the research community, is to integrate energy-generation and energy-storage devices into self-charging power systems (SCPSs), so that the scavenged energ...

Attachment insecurity and power regulation in intimate relationships.

Power and dependence are fundamental to the development of attachment insecurity and attachment insecurity is central in defining different ways people regulate power. This paper applies an integrated power and attachment perspective to advance understanding of the diverse ways people attempt to negotiate dependence and power in adult relationships. The paper demonstrates how: (1) power is integral to the concerns and goals underlying attachment avoidance and anxiety, (2) the situations that activate attach...

A Three-Dimensional Printed Poly(vinyl alcohol) Substrate with Controlled On-Demand Degradation for Transient Electronics.

Electronics that degrade after stable operation for a desired operating time, called transient electrons, are of great interest in many fields, including biomedical implants, secure memory devices, and environmental sensors. Thus, the development of transient materials is critical for the advancement of transient electronics and their applications. However, previous reports have mostly relied on achieving transience in aqueous solutions where the transience time is largely pre-determined based on the materi...

Michel Foucault and the Problematics of Power: Theorizing DTCA and Medicalized Subjectivity.

This article explores Foucault's two different notions of power: one where the subject is constituted by power-knowledge relations and another that emphasizes how power is a central feature of human action. By drawing out these two conceptualizations of power, Foucault's work contributes three critical points to the formation of medicalized subjectivities: (1) the issue of medicalization needs to be discussed both in terms of both specific practices and holistically (within the carceral archipelago); (2) we...

Impact of consumer power on consumers' reactions to corporate transgression.

We addressed how individuals' power influences their judgments regarding corporate transgressions. Based on the Situated Focus Theory of Power, which theorizes that powerful people respond more in accordance to circumstantial factors, we tested the interaction of power and the type of corporate discourse offered by the accused company. Across two studies (overall N = 216), we experimentally primed power (Study 1) and manipulated participants' sense of direct control over the company (Study 2). We consistent...

Inductor-Free Wireless Energy Delivery via Maxwell's Displacement Current from an Electrodeless Triboelectric Nanogenerator.

Wireless power delivery has been a dream technology for applications in medical science, security, radio frequency identification (RFID), and the internet of things, and is usually based on induction coils and/or antenna. Here, a new approach is demonstrated for wireless power delivery by using the Maxwell's displacement current generated by an electrodeless triboelectric nanogenerator (TENG) that directly harvests ambient mechanical energy. A rotary electrodeless TENG is fabricated using the contact and sl...

Probing Growth-Induced Anisotropic Thermal Transport in High-Quality CVD Diamond Membranes by Multi-frequency and Multi-spot-size Time-Domain Thermoreflectance.

The maximum output power of GaN-based high-electron mobility transistors is limited by high channel temperature induced by localized self-heating which degrades device performance and reliability. Chemical vapor deposition (CVD) diamond is an attractive candidate to aid in the extraction of this heat and in minimizing the peak operating temperatures of high power electronics. Due to its inhomogeneous structure, the thermal conductivity of CVD diamond varies along the growth direction and can differ between ...

Effect of the nanowire diameter on the linearity of the response of GaN-based heterostructured nanowire photodetectors.

Nanowire photodetectors are investigated because of their compatibility with flexible electronics, or for the implementation of on-chip optical interconnects. Such devices are characterized by ultrahigh photocurrent gain, but their photoresponse scales sublinearly with the optical power. Here, we present a study of single-nanowire photodetectors displaying a linear response to ultraviolet illumination. Their structure consists of a GaN nanowire incorporating an AlN/GaN/AlN heterostructure, which generates a...

Development of spatial representation of power in children.

Systematic evidence demonstrates that power is mentally represented as vertical space by adults. However, little is known about the developmental progress of such representation. Using the explicit power evaluation task, this study investigated the development of the spatial representation of power. Participants were Chinese children (5-7 years old) and adults. The results revealed that vertical motor responses interfered with responding for all age groups; that is, they responded to words representing po...

Although textile-based triboelectric nanogenerators (TENG) are highly promising as they scavenging energy from their working environment for sustainable powering wearable/mobile electronics, it remains a challenge to simultaneously possess the qualities of cloths. In this work, we propose strategy for TENG textiles as energy harvesting cloths that core-shell yarns, with core conductive fibers as the electrode and artificial polymer fibers or natural fibrous materials tightly twinning around core conductive ...

Observation of microwave absorption and emission from incoherent electron tunneling through a normal-metal-insulator-superconductor junction.

We experimentally study nanoscale normal-metal-insulator-superconductor junctions coupled to a superconducting microwave resonator. We observe that bias-voltage-controllable single-electron tunneling through the junctions gives rise to a direct conversion between the electrostatic energy and that of microwave photons. The measured power spectral density of the microwave radiation emitted by the resonator exceeds at high bias voltages that of an equivalent single-mode radiation source at 2.5 K although the...

Wearable conformal electronics are essential components for next-generation humanlike sensing devices that can accurately respond to external stimuli in non-planar and dynamic surfaces. However, to explore this potential, it is indispensable to achieve the desired level of deformability and charge transport mobility in strain-accommodating soft semiconductors. Here we show pseudo-two-dimensional freestanding conjugated polymer heterojunction nanosheets integrated into substrate-free conformal electronics, o...

A Comparison between Bench Press Throw and Ballistic Push-Up tests to assess upper-body power in trained individuals.

Twenty-eight experienced resistance trained men (age = 25.4 ± 5.2 y; body mass = 78.5 ± 9.0 kg; body height = 179.6 ± 7.8 cm) performed, two days apart, a bench press 1RM test and upper-body power tests. Mean power and peak power were assessed using the bench press throw test (BT) and the BPU test performed in randomized order. The area under the...

Beam quality improvement by controlling thermal lens spherical aberration in an end-pumped Nd:YVOlaser.

We present for the first time, to the best of our knowledge, the influence of spherical aberration on the beam quality of a single-stage laser amplifier. We set up an amplifier with a special structure to measure the spherical aberration distribution in the cavity. The output power of the oscillator was controlled, and the pump power of the amplifier was adjusted to improve the beam quality. The results show that there is an optimal amplifier pump power, which maximizes the output laser beam quality. In the...
