    Abstract There has been a considerable amount of interest in the ion-exchange properties of layered zirconium phosphates. Potential applications in the remediation of nuclear waste have renewed interest in these inorganic materials, due to their high stability under the acidic conditions typically found in legacy waste pools. It has been well documented that the substitution of metals with different ionic radii into the frameworks of inorganic materials can alter the chemical properties including ion-exchange selectivity. The work presented here focusses on the synthesis and characterisation of yttrium-doped α-zirconium phosphates which are reported for the first time. Two different synthetic methods were used, reflux and hydrothermal syntheses, and the products were characterised by various methods such as powdered X-ray diffraction, MAS-NMR and scanning electron microscopy. It was found that up to 15% of zirconium could be replaced by yttrium before any noticeable impurity phases could be observed. Rietveld refinement from the doping showed that the products did not obey the Vegard’s law. However, the ion-exchange results clearly showed enhanced capacities and selectivity towards Co 2+ ions for the substituted materials.

    Abstract Purpose of review: The purpose of this review is to summarize what is known in the literature about the role inflammation plays during bone fracture healing. Bone fracture healing progresses through four distinct yet overlapping phases: formation of the hematoma, development of the cartilaginous callus, development of the bony callus, and finally remodeling of the fracture callus. Throughout this process, inflammation plays a critical role in robust bone fracture healing.
    Recent findings: At the onset of injury, vessel and matrix disruption lead to the generation of an inflammatory response: inflammatory cells are recruited to the injury site where they differentiate, activate, and/or polarize to secrete cytokines for the purposes of cell signaling and cell recruitment. This process is altered by age and by sex. Bone fracture healing is heavily influenced by the presence of inflammatory cells and cytokines within the healing tissue.

  6. Article ; Online: WS 2 Nanosheet Loaded Silicon-Oxycarbide Electrode for Sodium and Potassium Batteries

    Abstract Transition metal dichalcogenides (TMDs) such as the WS 2 have been widely studied as potential electrode materials for lithium-ion batteries (LIB) owing to TMDs’ layered morphology and reversible conversion reaction with the alkali metals between 0 to 2 V (v/s Li/Li + ) potentials. However, works involving TMD materials as electrodes for sodium- (NIBs) and potassium-ion batteries (KIBs) are relatively few, mainly due to poor electrode performance arising from significant volume changes and pulverization by the larger size alkali-metal ions. Here, we show that Na + and K + cyclability in WS 2 TMD is improved by introducing WS 2 nanosheets in a chemically and mechanically robust matrix comprising precursor-derived ceramic (PDC) silicon oxycarbide (SiOC) material. The WS 2 /SiOC composite in fibermat morphology was achieved via electrospinning followed by thermolysis of a polymer solution consisting of a polysiloxane (precursor to SiOC) dispersed with exfoliated WS 2 nanosheets. The composite electrode was successfully tested in Na-ion and K-ion half-cells as a working electrode, which rendered the first cycle charge capacity of 474.88 mAh g −1 and 218.91 mAh g −1 , respectively. The synergistic effect of the composite electrode leads to higher capacity and improved coulombic efficiency compared to the neat WS 2 and neat SiOC materials in these cells.

    Abstract BACKGROUND: Due to concerns regarding the safety of the chemical control measures, the trend is shifting globally towards the use of natural compounds as antimicrobial agent especially, plant essential oils. RESULTS: This study presented the antibacterial potential of Cymbopogon khasianus essential oil (CKEO) against human pathogens: Pseudomonas aeruginosa, Salmonella typhimurium, Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Staphylococcus aureus and Candida albicans with MIC ranging from 20 to 100 μg/mL. CKEO, in comparison to its major constituent, geraniol, showed better MICs against tested pathogens. In combination studies, the effective concentrations of CKEO and streptomycin were reduced from 20 to 5 μg/mL and 11 to 0.7 ng/mL against E. coli. This suggests their synergistic action. However, CKEO showed partial synergy with ciprofloxacin. To understand the efficacy of CKEO, time-kill kinetics was performed. CKEO took the half time to show the bactericidal effect in comparison to streptomycin at their 2x MICs (double the MIC), while their combination took only 30 min for this. Fluorescence and surface electron microscopic and protein estimation studies suggested the multi-target action of CKEO-streptomycin combination against E. coli. Further, CKEO alone/in combination exhibited less than 10% haemolytic activity at its MIC. CONCLUSION: These results indicate that CKEO is a potentially safe alternative for the treatment of various pathogenic bacterial strains. It could be used for a variety of applications including human health, food storage, aquaculture, etc.

    Abstract Spontaneous coronary artery dissection (SCAD) is an epicardial coronary artery dissection not associated with atherosclerosis or trauma, and is not iatrogenic. The pathogenesis of SCAD is not fully understood, and the association of coronary artery anomalies and SCAD is not known. We present a case of a 64-year-old woman presenting with non-ST-elevation myocardial infarction (NSTEMI) due to have multivessel SCAD in the setting of anomalous origin of the coronary arteries with all three coronary arteries – right coronary artery (RCA), left anterior descending artery (LAD), and left circumflex artery (LCx) originating from the right sinus of Valsalva.

    Abstract Human skin exhibits highly varying mechanical properties, thickness, hardness, and anisotropy by virtue of changing fiber distributions and orientations, across different body locations. To date, only a few studies have computationally simulated skin anisotropy and no experimental study on synthetic skin exists which can mimic the accurate biomechanical properties of the skin. In this work, unique anisotropic synthetic skin samples were created using an elastic composite-based structure. Both single and multi-layer synthetic skin were fabricated with consistent fiber density and fiber dimensions and varying fiber angles to generate over 100 compositions. The compositions implied stress versus stretch responses in mechanical biaxial testing were compared to those of the skin of a person. Hyperelastic constitutive models were used to characterize the non-uniform test results. The created anisotropic synthetic skin must be essential for reliable Biomechanical investigation of skin free from ethical concerns, undertaking medical training and researching skin pathophysiology and injuries.
