residual microorganisms in the root canal system (rcs) after endodontic therapy such as candida albicans are a major cause of endodontic failure. calcium hydroxide (ch) and chlorhexidine (chx) have suitable antimicrobial activity against bacteria and can be used as intracanal medicaments. nanosilver has also shown antimicrobial activity against microorganisms. this study aimed to compare the an...

During traditional acupuncture, fine needles are inserted subcutaneously and rotated, which causes loose fascial tissue to wind around the needle. This coupling is stronger at acupuncture points, which tend to fall above intermuscular fascial planes, than control points, which lay above skeletal muscle. These different anatomical constraints may affect the mechanical coupling. Fascia at acupunc...

Solutions of nanoparticles can be used as a general platform to design glues for polymer-based gels. However, optimization the system specific gel type requires understanding how different...

Abstract The reliable sampling of root exudates in soil-grown plants is experimentally challenging. This study aimed at developing a citrate and mapping technique with millimetre-resolution using DGT (diffusive gradients thin films) ZrOH-binding gels. Citrate adsorption kinetics, capacity, stability ZrOH gels were evaluated. applied to generate 2D maps exuded by white lupin roots grown rhizotro...

Recently, polymer gels have drawn much attention as scaffolds for regenerative medicines, soft actuators, and functional membranes. These applications need tough and robust polymer gels as represented by the double network gels. To fully understand this mechanism and develop further advanced polymer gels, we need to fully understand the molecular origin of fracture energy for conventional polym...

Using rheometry and light scattering, we have studied the viscoelasticity of gels formed by the kinetically arrested phase separation in an emulsion-polymer mixture; to prevent the gels from collapsing under their own weight, we have used an isopycnic solvent. At constant osmotic pressure (set by the polymer concentration) and droplet volume fractionsφ well above the gelation transition, we fin...

Automatic repair: a polymer with pendent dibenzo[24]crown-8 units (purple in picture) was cross-linked by two bisammonium salts (green) to form two supramolecular gels based on host-guest interactions. These two gels are stimuli-responsive materials that respond to changes of the pH value and are also self-healing materials, as can be seen by eye and as evidenced by rheological data.

Purpose: The usage of herbal-based antibacterial sanitizers is increasing, and they have considerably shown fewer side-effects than with synthetic compounds. In the present study, essential oils obtained from cinnamon lime were used to formulate hand sanitizer gels, their efficacy was evaluated. Method: Three different gel formulations prepared using oil (Formulation A), B) a mixture C). Carbop...
