Halloysite nanotube (HNT) and clay are introduced into multi-walled carbon nanotube (MWCNT)/fluoroelastomer (FKM) composites to improve electrical conductivity without harming mechanical and thermal properties. Hence, it has been achieved by combining the fillers (HNT and clay) with MWCNT which restricts the agglomeration of MWCNT in the matrix and allows the uniform dispersion. With just 2 wt% HNT and Clay, electrical conductivity is increased by more than four orders of magnitude (from 10(-8) to 10(-4) S/cm). Furthermore, the percolation threshold of these nanocomposites is reduced with the addition of 2 wt% HNT and clay. MWCNTs appear to have an affinity for clay that causes them to become more exfoliated in these composites. This HNT/clay-nanotube synergy may make these composites better suited for high electrical properties along with high mechanical and thermal applications.

MgO surface makes it easy to introduce a certain amount of oxygen vacancy and can enhance catalytic reaction activity. Besides, as a silicoaluminate mineral material, halloysite nanotube (HNT) has a unique tubular structure. In this paper, the HNTs@MgO composite was successfully synthesized based on natural clay material HNTs as a carrier, and the CTL sensor based on HNTs@MgO was successfully developed for the rapid determination of ether in air.

Background/objectives: The development of therapies targeting unregulated Src signaling through selective kinase inhibition using small-molecule inhibitors presents a significant challenge for the scientific community. Among these inhibitors, pyrazolo[3,4-]pyrimidine heterocycles have emerged as potent agents; however, their clinical application is hindered by low solubility in water. To overcome this limitation, some carrier systems, such as halloysite nanotubes (HNTs), can be used.

Metoclopramide is an antiemetic agent prescribed for motion sickness, cancer chemotherapy, and pregnancy. The present work aimed to design a metoclopramide-loaded halloysite nanotubes (HNTs) drug-in-adhesive transdermal drug delivery system. Four formulations F1, F2, and F3 with different ratios of HNTs to metoclopramide and a F4 without HNTs were developed using acrylic adhesive DURO-TAK 387-2510 by the solvent casting method.

Photocatalysis stands out as a promising technique for treating organic contaminants, yet the quest for visible light active composite materials, crafted through cost-effective, eco-friendly, and uncomplicated processes, poses formidable challenges. Here, we introduce a successful endeavor, the synthesis of a CuO/SnO (CS) composite via a microwave method, employing fruit extract as a reducing as well as capping agent. Various loadings of CS-HNT composites were prepared by ultrasonically incorporating CS onto nanotubular halloysite (HNT) clay.

The purpose of this study is to formulate and characterize the cryogels containing halloysite nanotube (HNT)/lipase nanohybrid (NH-cryogel) in comparison to pure cryogels as well as cryogels containing lipase (lipase-cryogel). The cryogels were synthesized using polyvinyl alcohol (PVA) and sodium alginate (SA). The products are tested to explore the influence of the HNT/lipase nanohybride (NH) as nanofillers on the cryogel properties using methods such as swelling degree, water uptake measurement, TGA, XRD, FESEM and FTIR.
