Packing Activated Carbons into Dense Graphene Network by Capillarity for High Volumetric Performance Supercapacitors

open access: yesAdvanced Science, 2019
Supercapacitors are increasingly in demand among energy storage devices. Due to their abundant porosity and low cost, activated carbons are the most promising electrode materials and have been commercialized in supercapacitors for many years.

Mathematical models of the Earth’s density structure and their applications in gravimetric forward modeling

open access: yesContributions to Geophysics and Geodesy, 2015
A generalized mathematical model of the Earth’s density structure is presented in this study. This model is defined based on applying the spectral expressions for a 3-D density distribution within the arbitrary volumetric mass layers.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Interplay of BMI and volumetric breast density measures and breast cancer risk for black and white women

open access: yesBreast Cancer Research
Background Black women have lower Breast Imaging Reporting and Data System (BI-RADS) breast density than White women, likely due to body mass index (BMI) differences.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Estimating body volumes and surface areas of animals from cross-sections [PDF]

open access: yesPeerJ
Background Body mass and surface area are among the most important biological properties, but such information is lacking for some extant organisms and most extinct species.

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Reduction of volumetric density of collagen fibers, fibroblasts and blood vessels in diabetic groups.

open access: yes, 2013
Histological sections of diabetic rats were investigated by morphometrical analyses for: a) volumetric density of collagen fibers, b) volumetric density of fibroblasts, c) volumetric density of blood vessels.
