Acetyl salicylic acid–ZnAl layered double hydroxide functional nanohybrid for skin care application

Author: Mosangi, Damodar ; Moyo, Lumbidzani ; Kesavan Pillai, Sreejarani ; Ray, Suprakas S Date: Oct 2016 In this study, a pharmaceutically active ingredient, acetyl salicylic acid (ASA), was intercalated into ZnAl layered double hydroxide (LDH). The LDH–ASA nanohybrid material was characterized by XRD, FTIR, SEM, ICP-MS, TEM and TGA. Successful ... Read more c b
Anomalous impact strength for layered double hydroxide-palmitate/poly(e-caprolactone) nanocomposites

Author: Moyo, Lumbidzani ; Makhado, E ; Ray, Suprakas S Date: Nov 2014 Inherent physical properties and commercial availability makes poly(e-caprolactone) (PCL) very attractive as a potential substitute material for nondegradable polymers for commodity applications. However, a balance of toughness and stiffness ... Read more
The influence of filler surface modification on mechanical and material properties of layered double hydroxide -containing polypropylene composites

Author: Moyo, Lumbidzani ; Ray, Suprakas S ; Sebati, Ngwanamohuba W ; Ojijo, Vincent O Date: Mar 2017 The processing and properties of layered double hydroxides (LDHs)-containing polypropylene (PP) composites have been studied extensively. However, no detailed studies have reported on how stearic acid (SA)-intercalated and SA-coated LDHs ... Read more
Inorganic layered double hydroxides as a 4-hexyl resorcinol delivery system for topical applications

Author: Mosangi, Damodar ; Kesavan Pillai, Sreejarani ; Moyo, Lumbidzani ; Ray, Suprakas S Date: Aug 2016 In this study, the hydrophobic even skin tone active, 4-hexylresorcinol (HR), was intercalated into a zinc aluminium layered double hydroxide (ZnAl-LDH) by a co-precipitation method and used as a controlled release ingredient in skin care ...
