Impacts of halloysite clay nanoparticles on the structural and γ-ray shielding properties of the epoxy resin

Nuclear Engineering and Technology, 2023
In this study, halloysite nanoparticles-doped epoxy resin was synthesised using the casting method. The MH-300A density metre revealed that the density of the fabricated composites changed from 1.132 to 1.317 g/cm3 as the halloysite nanoparticle ...

Engineering Nanoclay Edges to Construct Effective Polysulfide‐Trapping Interface for Markedly Enhanced Electrochemical Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between

Biodegradable and Water Resistant Poly(vinyl) Alcohol (PVA)/Starch (ST)/Glycerol (GL)/Halloysite Nanotube (HNT) Nanocomposite Films for Sustainable Food Packaging

Frontiers in Materials, 2019
As a novel biodegradable material, poly (vinyl) alcohol (PVA)/starch (ST)/ glycerol (GL)/ halloysite nanotube (HNT) nanocomposite films were prepared by solution casting at the HNT contents of 0.25, 0.5, 1, 3 and 5 wt%.

Soils and paleosoils of the Galapagos Islands : what we know and what we don't know, a meta-analysis [PDF]

, 2014
Accessible information on Galapagos soils is very limited. Much of the existing, although still scarce, information is several decades old and not easily retrieved. The aim of this paper is to present a critical synthesis.

Effect of Adding Halloysite to Different Solid Biomass Fuels on Combustion Process in a Small-Scale Domestic Retort Boiler

Energies
Biomass combustion in small-scale boilers in Eastern Europe has recently become a very popular heating option. Biomass boilers are gradually replacing old, coal-fired installations, especially in the domestic sector.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Solid-state NMR characterisation of the thermal transformation of a Hungarian white illite [PDF]

, 2005
1H, 27Al, 29Si and 39K solid-state NMR are reported from a Hungarian illite 2:1 clay for samples heated up 1600 °C. This single-phase sample has a small amount of aluminium substitution in the silica layer and very low iron-content (0.4 wt%).

Design of Etched- and Functionalized-Halloysite/Meloxicam Hybrids: A Tool for Enhancing Drug Solubility and Dissolution Rate

Pharmaceutics
The study focuses on the synthesis and characterization of Meloxicam–halloysite nanotube (HNT) composites as a viable approach to enhance the solubility and dissolution rate of meloxicam, a poorly water-soluble drug (BCS class II). Meloxicam is loaded on
