Into the Void: Single Nanopore in Colloidally Synthesized BiTe Nanoplates with Ultralow Lattice Thermal Conductivity.

BiTe is a well-known thermoelectric material that was first investigated in the 1960s, optimized over decades, and is now one of the highest performing room-temperature thermoelectric materials to-date. Herein, we report on the colloidal synthesis, growth mechanism, and thermoelectric properties of BiTe nanoplates with a single nanopore in the center. Analysis of the reaction products during the colloidal synthesis reveals that the reaction progresses via a two-step nucleation and epitaxial growth: first of elemental Te nanorods and then the binary BiTe nanoplate growth.

High Thermoelectric Performance in 2D SbTe and BiTe Nanoplate Composites Enabled by Energy Carrier Filtering and Low Thermal Conductivity.

Thermoelectrics are an important class of materials with great potential in alternative energy applications. In this study, two-dimensional (2D) nanoplates of the layered chalcogenides, SbTe and BiTe, are synthesized and composites of the two are investigated for their thermoelectric properties. The two materials, SbTe and BiTe, were synthesized as hexagonal, 2D nanoplates via a colloidal polyol route.

MRI morphometry of the anterior and posterior cerebellar vermis and its relationship to sensorimotor and cognitive functions in children.

Introduction: The human cerebellum emerges as a posterior brain structure integrating neural networks for sensorimotor, cognitive, and emotional processing across the lifespan. Developmental studies of the cerebellar anatomy and function are scant. We examine age-dependent MRI morphometry of the anterior cerebellar vermis, lobules I-V and posterior neocortical lobules VI-VII and their relationship to sensorimotor and cognitive functions.

Thermoelectric Properties of BaEuZnSb, a Zintl Phase with One-Dimensional Covalent Chains.

The compound BaZnSb has been predicted to be a promising thermoelectric material, potentially achieving > 2 at 900 K due to its one-dimensional chains of edge-shared [ZnSb] tetrahedra and interspersed Ba cations. However, the high air sensitivity of this material makes it difficult to measure its thermoelectric properties. In this work, isovalent substitution of Eu for Ba was carried out to make BaEuZnSb in order to improve the stability of the material in air and to allow characterization of thermal and electronic properties of three different compositions ( = 0.

Posterior brain sensorimotor recruitment for inhibition of delayed responses in children.

Inhibitory control, the ability to suppress irrelevant thoughts or actions, is central to cognitive and social development. Protracted maturation of frontal brain networks has been reported as a major restraint for this ability, yet, young children, when motivated, successfully inhibit delayed responses. A better understanding of the age-dependent neural inhibitory mechanism operating during the awaiting-to-respond window in children may elucidate this conundrum.

Frontoparietal network and neuropsychological measures in typically developing children.

Resting-state activity has been used to gain a broader understanding of typical and aberrant developmental changes. However, the developmental trajectory of resting-state activity in relation to cognitive performance has not been studied in detail. The present study assessed spectral characteristics of theta (5-8 Hz) and alpha (9-13 Hz) frequency bands during resting-state in a priori selected regions of the frontoparietal network (FPN).

"I'm not going to be a guinea pig:" Medical mistrust as a barrier to male contraception for Black American men in Los Angeles, CA.

Background: Racial disparities in unintended pregnancy and contraceptive use in the United States are not mediated by access to family planning services alone. Rather, a history of medical mistrust underlies Black Americans' adoption of new medical technologies, inclusive of contraception. Efforts to develop hormonal male contraceptives need to incorporate Black Americans' experiences and perspectives so that new contraceptives enable their reproductive goals and promote gender equity.

Measurements of the thermopower, electrical resistivity, and thermal conductivity were performed in the wide temperature range 2-950 K. The material appeared as a -type conductor, with a fairly large, positive Seebeck coefficient of about 240 μV K near 450 K.

Maturational Changes in Human Dorsal and Ventral Visual Networks.

Developmental neuroimaging studies report the emergence of increasingly diverse cognitive functions as closely entangled with a rise-fall modulation of cortical thickness (CTh), structural cortical and white-matter connectivity, and a time-course for the experience-dependent selective elimination of the overproduced synapses. We examine which of two visual processing networks, the dorsal (DVN; prefrontal, parietal nodes) or ventral (VVN; frontal-temporal, fusiform nodes) matures first, thus leading the neuro-cognitive developmental trajectory. Three age-dependent measures are reported: (i) the CTh at network nodes; (ii) the matrix of intra-network structural connectivity (edges); and (iii) the proficiency in network-related neuropsychological tests.

The use of a low-literacy version of the Medicaid sterilization consent form to assess sterilization-related knowledge in Spanish-speaking women: results from a randomized controlled trial.

Objective: To learn whether a version of the Medicaid Sterilization Consent Form (SCF) adapted for populations of low-literacy can help Spanish-speaking women better understand the process and consequences of tubal sterilization.

Study Design: We randomly assigned Spanish-speaking women, ages 21-45 years, to review either a "standard" or "low-literacy" version of the Medicaid SCF. We assessed sterilization-related knowledge using items from the Postpartum Tubal Sterilization Knowledge questionnaire, using as the primary outcome correct identification of least four or more knowledge items and as secondary outcome participants' preferred version of the SCF.
