“…Similarly, we found that polyaniline‐montrmorillonite clay nanocomposite materials display notable ER effects and good suspension stability compared with the pure polyaniline particles, but these kinds of materials are far from use in the green process9 because of their toxicity. Recently, some organic polymers that contain polysaccharide or consist of glucose units, such as chitosan,10–13 phosphate cellulose,14 kaolinite‐carboxymethyl starch,15 and polysaccharide/titanium oxide,16 have attracted researchers. One of the advantages of these materials is lack of toxicity.…”

Development of the lip and palate involves a complex series of events that are frequently disturbed resulting in the congenital anomalies cleft lip and cleft palate. Van der Woude syndrome (VWS) is an autosomal dominant disorder that is characterised by cleft lip, cleft palate, lower lip pits, and hypodontia. VWS arises as the result of mutations in the gene encoding interferon regulatory factor 6 (IRF6). To provide insights into the role of IRF6 during embryogenesis, we have analysed the expression of this molecule during mouse and chick facial development. Irf6 was expressed in the ectoderm covering the facial processes during their fusion to form the upper lip and primary palate in both mouse and chick. However, while Irf6 was expressed in the medial edge epithelia of the developing secondary palate of the mouse, which fuses as in man, Irf6 was not expressed in the medial edge epithelia of the naturally cleft chick secondary palate. Similarly, Irf6 was found to be down-regulated in the medial edge epithelia of transforming growth factor beta3-null mice, which also exhibit cleft palate. Together, these results support a role for IRF6 during the fusion events that occur during development of the lip and palate. Developmental

“…[54,55]. Both, positive and negative ER fluids can be used in applications [56][57][58], such as valves, dampers, journal bearings, microelectromechanical systems (MEMS), etc. Materials in liquid state, that can be excited by an external electric field without any additives are called natural ER fluids.…”

This review paper highlights the tribological behaviour and performance of smart fluids. Two main kinds of smart fluids, that respond to a suitable external stimulus are investigated -electrorheological and magnetorheological fluid. The excitation of an external active field significantly increases or decreases the fluidity, depending on the fluid type. First, the tribological behaviour of both types of smart fluids without the influence of an external field and under the external active field, respectively, are reviewed. Subsequently, the influence of external field activation on the lubricating layer is described. Finally, a summary of the most notable findings of investigated smart fluids performance and behaviour is provided. Possible future applications are then considered for smart lubricants technology and engineering devices.

In the current study, a series of hollow resins has been synthesized by using chitosan succinate and urea-formaldehyde resin as a cage resin to prepare new polychelates for different metal ions. Resins were characterized by FT-IR spectroscopy, thermal analysis and scanning electron microscopy. Resins have also been investigated for the removal of metal ions from their aqueous solutions through the formation of polychelates of the metal ions and their sorption capacity of such metal ions was determined. The hollow resin exhibited higher surface area than its separate components which facilitates higher ion uptake of metal ions from aqueous solutions.
