Carpet cloaking on a dielectric half-space

open access: yes, 2010
Carpet cloaking is proposed to hide an object on a dielectric half-space from electromagnetic (EM) detection. A two-dimensional conformal transformation specified by an analytic function is utilized for the design. Only one nonsingular material parameter

“And in some cases, we're the best option:” A qualitative study of community‐based doula support for black perinatal mental health

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract We explored community‐based doulas' perspectives on the acceptability of using formal screening tools to address low rates of mental health screening, diagnosis, and treatment for perinatal anxiety and depression among Black women. Using thematic analysis, we analyzed interview data from 30 community‐based doulas who support Black families ...

Mechanistic Insights Into Cellulose Dissolution in Solvents for Advanced Industrial Applications: A Systematic and Bibliometric Review

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability.

The Influence of Nanoclay on the Flame Retardancy and Mechanical Performance of Recycled Carpet Composites

open access: yesRecycling, 2019
In the present study, we recycled waste carpet using a vacuum-assisted resin transfer molding (VARTM) process. Three different variations of carpet composites were fabricated, namely, neat epoxy, clay-coated, and clay-infused carpet composites.

Are they two seeds in a pod? Comparing seed rain recovery in grasslands using artificial grass carpets versus sticky traps

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Seed dispersal is a critical process for plant community assembly; however, natural rates of seed arrival are rarely quantified compared with other assembly mechanisms, especially in herbaceous communities. Methods Here we compare the utility of artificial grass carpet squares (“artificial grass”) for capturing seed rain with classic ...
