Characterization and evaluation of porous hydroxyapatite synthesized by oil-in-water method as carrier of donepezil for the preventive of Alzheimer’s disease by controlled release

open access: yesJournal of Asian Ceramic Societies, 2020
Alzheimer’s disease (AD) is the most common cause of dementia. Patients are generally to forget taking pills because of memory loss or to skip medication due to side effects; that might stop the medication and affect the results of the treatment. In this

Study of a Mixed Alkaline–Earth Effect on Some Properties of Glasses of the CaO-MgO-Al2O3-SiO2 System

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2007
In the present work, we studied a “Mixed Alkaline–Earth Effect”, i.e. the non-linear behaviour showed by the glass transition temperature as well as by the compressive strength of glasses of the CaO-MgO-Al2O3-SiO2 system, when a part of the CaO contained

Nanofillers to Improve the Barrier Properties of Biobased Substrates of Flexible Printed Electronics

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Replacing the fossil‐based substrates of supercapacitors containing liquid electrolytes with biopolymers requires an improvement in their barrier properties. Here, the abilities of three different nanofillers to lower the permeabilities of biopolymers are investigated. 20 w‐% of nanoclay Nanomer I.28E mixed into polyhydroxybutyrate has the best barrier

Maintaining egg freshness in the absence of refrigeration: The potential of zero‐energy cooling pots

open access: yesJSFA reports, Volume 6, Issue 8, Page 301-308, August 2026.
Abstract Background Egg storage in regions with unreliable electricity is challenging, leading to rapid quality deterioration and postharvest losses. This study evaluated the efficacy of a Zero‐Energy Cooling (ZEC) pot, an evaporative cooling technology, for preserving table egg quality in comparison to conventional refrigeration and ambient storage ...
