“…31 MC microspheres based on MC have been obtained using the water-in-oil emulsion method by adding GA and HCl in the oil phase to achieve crosslinking (crosslinking time range: 30 min to 3 h, room temperature). In this regard, MC has always been used in a blend with other polymers like alginate, 33 chitosan, [34][35][36] and polyvinyl alcohol (PVA) 37 for the controlled release of drugs. Blending was selected to modify the blend's physicochemical properties (swelling and degradation) or provide additional functionalities (e.g., pH responsiveness and antibacterial activity for chitosan).…”

We presented the first photometric and orbital period investigations for a neglected total-eclipse contact binary IP Lyn. The photometric solutions derived from both ground-based and several surveys' observations suggested that it is a shallow contact binary with an extremely low mass ratio of 0.055. The weak asymmetry observed in our multiple bands light curves can be interpreted as a result of an active cool spot on the primary. The absolute physical parameters were determined with the {\it Gaia}-distance-based method and checked by an empirical relation. Combining the eclipse timings collected from the literature and those derived from our and variable surveys' observations, we found that IP Lyn has been undergoing a secular orbital period increase for the past two decades, implying a mass transfer from the less massive secondary to the primary. By comparing the current parameters with the critical instability ones, we inferred that IP Lyn is currently stable in spite of its relatively low mass ratio and orbital angular momentum. Finally, from a catalog of 117 extremely low mass ratio contact binaries, we found that their orbital angular momenta are significantly lower than those of the contact binaries with a relatively high mass ratio, suggesting they should be at the late evolutionary stage of contact binary.
