School of Physics and Optoelectronics, Xiangtan University, School of Physics and Optoelectronics, Xiangtan University, Hunan 411105, PR China, Xiangtan, Hunan, 411105, CHINA.

Herein, FePS3/reduced graphene oxide (rGO) heterostructure has been prepared via a typical hydrothermal process, and flexible photodetectors based on hybrids have been subsequently fabricated. The photoresponse measurement results demonstrate that the photodetector exhibits obvious photoelectric conversion behavior without applied potential, indicating the device possesses capability of self-powered. In addition, the photocurrent density of as-fabricated photodetectors reaches up to 125 nA/cm2 under 90 mW/cm2 of illumination intensity without external power source, which is 5. Read More

A CMOS-compatible morphotropic phase boundary.

Nanotechnology 2021 Jul 22. Epub 2021 Jul 22.

Pohang University of Science and Technology, Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH) 77 Cheongam-Ro, Nam-Gu, Pohang, Gyungbuk, Korea, Pohang, Pohang, 37673, Korea (the Republic of).

Morphotropic phase boundaries (MPBs) show substantial piezoelectric and dielectric responses, which have practical applications. The predicted existence of MPB in HfO2-ZrO2 solid solution thin film has provided a new way to increase the dielectric properties of a silicon-compatible device. Here, we present a new fabrication design by which the density of MPB ρ_(MPB )and consequently the dielectric constant ϵr of HfO2-ZrO2 thin film was considerably increased. Read More

Iron-rich microstructure records of high temperature multi-component silicate melt behavior in nuclear fallout.

J Environ Radioact 2021 Jul 19;237:106700. Epub 2021 Jul 19.

Department of Nuclear Engineering, University of California, Berkeley, USA.

Above-ground nuclear explosions that interact with the surface of the earth entrain materials from the surrounding environment, influencing the resulting physical and chemical evolution of the fireball, which can affect the final chemical phase and mobility of hazardous radionuclides that are dispersed in the environment as fallout particles. The interaction of iron with a nuclear explosion is of specific interest due to the potential for iron to act as a redox buffer and because of the likelihood of significant masses of metals to be present in urban environments. We investigated fallout from a historic surface interacting nuclear explosion conducted on a steel tower and report the discovery of widespread and diverse iron-rich micro-structures preserved within the samples, including crystalline dendrites and micron-scale iron-rich spheres with liquid immiscibility textures.

Disgust uniquely predicts coping and interpersonal processes beyond anxiety and dysphoria in the context of naturalistic stressors.

J Anxiety Disord 2021 Jul 9;82:102446. Epub 2021 Jul 9.

Seattle Pacific University, United States. Electronic address:

Background: Disgust is theorized to serve a unique function of motivating avoidance of noxious stimuli and setting interpersonal boundaries to prevent contamination. Research has established the relevance of disgust to OCD, posttraumatic stress, and phobias, suggesting transdiagnostic features. However, research has not always accounted for overlap of disgust with other negative emotions, obscuring unique contributions. Read More

"Why can't you sit still?"The effect of daily physical activity on childhood inattention/hyperactivity and the educational gender gap.

Soc Sci Med 2021 Jul 16;284:114232. Epub 2021 Jul 16.

Department of Economics, Dalhousie University, Halifax, Nova Scotia, B3H 4R2, Canada. Electronic address:

Despite the compelling evidence of the long-run consequences of childhood inattention/hyperactivity and harmful side effects of stimulant medication, relatively little is known about accessible non-pharmacological options to reduce inattentive/hyperactive behaviours. This study evaluates the effect of daily exercise on inattentive/hyperactive behaviours among young children by leveraging evidence from a quasi-experiment generated when 3 Canadian provinces adopted mandatory requirements for all students in grades 1 through 6 to participate in 20-30 min of daily physical activity at school between 1994 and 2009. By exploiting plausibly exogenous variations in the timing of implementation and duration of physical activity mandated as well as over 20,000 observations on a sample of nationally representative children, our difference-in-differences estimates indicate that brief bouts of daily exercise at school effectively reduce inattention/hyperactivity in children - with the beneficial effect enhanced by the duration of exercise mandated.

Flow inside a bone scaffold: Visualization using 3D phase contrast MRI and comparison with numerical simulations.

J Biomech 2021 Jul 12;126:110625. Epub 2021 Jul 12.

Department of Mechanical and Industrial Engineering, University of Massachusetts, Amherst, MA, USA. Electronic address:

We report on results of experimental flow measurements inside a bone scaffold model, subjected to a uniform incoming flow (applied perfusion). Understanding the flow behavior inside a tissue engineered scaffold is essential for mechanistic studies of mechanobiology, particularly flow-sensitive bone cells. Nearly all existing studies that quantify interstitial flow inside engineered bone scaffolds have been based on numerical results, in part due to the difficulties associated with quantitative measurements and visualization of flow inside large, opaque bone or bone mimics.

State Key Laboratory for Mechanical Behavior of Materials, Xi'an Jiaotong University, Xi'an 710049, PR China. Electronic address:

Highly efficient electrochemical catalysts for oxygen reduction reactions (ORRs) are urgently needed for various energy conversion and storage devices to overcome sluggish ORR kinetics. Here, N,O-codoped carbon spheres with uniform mesopores and a high specific surface area were used as supports for decorating CoO nanoparticles via a facile immersion route. In addition to the benefit of ions and gas mass transfer, the abundant mesopores present in the three-dimensional (3D) carbon spheres also confine and isolate the CoO nanoparticles growing in it, which help to provide rich CoO active sites.

NICM Health Research Institute, Western Sydney University, Penrith, NSW 2751, Australia. Electronic address:

The association between human gut microbiota and cancers has been an evolving field of biomedical research in recent years. The gut microbiota is composed of the microorganisms residing in the gastrointestinal system that interact with the host to regulate behaviours and biochemical processes within the gut. This symbiotic physiological interaction between the gut and the microbiota plays a significant role in the modulation of gut homeostasis, in which perturbations to the microbiota, also known as dysbiosis can lead to the onset of diseases, including cancer.

Laboratory of Protein Conformation and Dynamics, Biochemistry and Biophysics Center, National Heart, Lung, and Blood Institute, National Institutes of Health, United States. Electronic address:

The pre-melanosomal protein (Pmel17) is a human functional amyloid that supports melanin biosynthesis within melanocytes. This occurs in the melanosome, a membrane-bound organelle with an acidic intraluminal pH. The repeat region of Pmel17 (RPT, residues 315-444) has been previously shown to form amyloid aggregates under acidic melanosomal conditions, but not under neutral cytosolic conditions, when expressed and purified using a C-terminal hexa-histidine tag (RPT-His).
