Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Sound attenuation apparatus [PDF]

open access: yes, 1991
An apparatus is disclosed for reducing acoustic transmission from mechanical or acoustic sources by means of a double wall partition, within which an acoustic pressure field is generated by at least one secondary acoustic source.

ON THE SCATTERING OF SOUND BY SOUND

open access: yesActa Physica Sinica, 1976
The problem of the non-linear interaction between two fully collimated plane-wave beams travelling in different directions has given rise to much of the controversy to date as to whether the secondary scattered radiation exists outside the interaction region. Ingard et al. expressed the primary beams with a type of discontinuous function ρ={ej(w-ky),|x|

Metal Nanoclusters for Cancer Imaging and Treatment

open access: yesAdvanced Functional Materials, EarlyView.
This review aims to provide a comprehensive summary and discussion of the core–shell design capabilities of metal nanoclusters (NCs) at the atomic level for cancer imaging and treatment. It offers essential insights into the design principles of metal NCs while also encouraging the exploration of other nanomaterials and their potential theranostic ...

Liver Disease Mini-Residency

open access: yesMedEdPORTAL, 2013
Introduction Liver and biliary symptoms led to over 450,000 outpatient clinic visits per year in the US in 2009. By default, primary care providers (PCPs) in rural or underserved communities often manage liver disease without ready access to specialist ...

Steep‐Switching Memory FET for Noise‐Resistant Reservoir Computing System

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate the steep‐switching memory FET with CuInP2S6/h‐BN/α‐In2Se3 heterostructure for application in noise‐resistant reservoir computing systems. The proposed device achieves steep switching characteristics (SSPGM = 19 mV/dec and SSERS = 23 mV/dec) through stabilization between CuInP2S6 and h‐BN.

A Mouse Model of Beta-Cell Dysfunction as Seen in Human Type 2 Diabetes

open access: yesJournal of Diabetes Research, 2018
Loss of first-phase insulin release is an early pathogenic feature of type 2 diabetes (T2D). Various mouse models exist to study T2D; however, few recapitulate the early β-cell defects seen in humans.
