An aqua-coordinated lamellar net [Zn(5-NH2-1,3-bdc)(H2O)] (1, 5-NH2-1,3-H2bdc = 5-amino-1,3-benzenedicarboxylic acid) has been found to undergo a reversible stimuli-responsive 2D-to-2D crystal-to-crystal transformation with a water-free bilayered-lamellar net [Zn(5-NH2-1,3-bdc)] (1′) upon removal and rebinding of aqua ligands, whereas a 2D porous pillared-bilayer [Zn2(5-NH2-1,3-bdc)2(NI-bpy-44)]·DMF (2, NI-bpy-44 = N-(pyridin-4-yl)-4-(pyridin-4-yl)-1,8-naphthalimide) has been tailored by introducing NI-bpy-44 to replace the coordinated aqua ligands. Pillared-bilayer 2 displayed a moderate CO2 uptake of 79.1 cm3 g−1 STP at P/P0 = 1 and 195 K with an isosteric heat of CO2 adsorption (Qst) of 37.0 kJ mol−1 at zero-loading. It is noteworthy that the water suspensions of 1 and 2 both displayed good fluorescence performances, which were effectively quenched by Fe3+, MnO4−, and Cr2O72− ions and shifted to long wavelengths by Fe3+, Al3+, and Cr3+, even with the coexistence of equal amounts of most other interfering ions. Taking the Stern–Volmer quenching constant, limit of detection, quenching efficiency, anti-interference ability, and visual observation into consideration, it is clear that both 1 and 2 are promising and excellent fluorescent sensors for highly sensitive detection of Fe3+, MnO4−, and Cr2O72−.

Eyelid reconstruction includes anterior lamella reconstruction and posterior lamella reconstruction. As an important skeletal component of the posterior lamella, tarsal plates repair is the key issue for eyelid reconstruction. Presently, neither traditional surgery nor autograft/allograft has achieved satisfactory repair effects. Poly(propylene fumarate)-co-2-hydroxyethyl methacrylate (PPF-HEMA) networks with mass ratios of 1 : 0.5, 1 : 1 and 1 : 2 were synthesized and used as the tarsal substitute in this study. Their chemical compositions, swelling ability, and mechanical properties were characterized. Porous scaffolds were fabricated by a gelatin particle leaching method. The in vitro studies of cytotoxicity on human dermal fibroblasts (HDFs) and degradation demonstrated that PPF-HEMA scaffolds did not have noticeable cell cytotoxicity and their degradation rates correlated with the ratio of PPF to HEMA. The PPF-HEMA networks, with mass ratios of 1 : 1 and 1 : 2, and an ADM control were implanted in rabbits with tarsal plate defects for in vivo biocompatibility and degradation behavior evaluation. PPF-HEMA scaffolds provided satisfactory repair results with mild tissue response and biocompatibility to fibroblast growth and fibrous capsulation compared to the ADM control. The tissue compatible and biodegradable PPF-HEMA networks with elastic mechanical properties were proven to be a suitable candidate for tarsal repair.

The phase behavior of the ABCA tetrablock copolymers in A-selective solvents is investigated using Lattice Monte Carlo simulation. The main focus is the effects of the solvophobic interactions of blocks B and C (eBS and eCS) on the micelle morphologies. Three kinds of ABCA tetrablock copolymers, i.e., A2B6C6A2, A2B7C5A2 and A2B8C4A2 tetrablock copolymers, are considered. Phase diagrams of these three tetrablock copolymers as a function of eCS and the solvophobic interaction difference between blocks B and C (which is measured by r = eBS/eCS) are given and discussed. It is found that r and eCS can both affect the specific surface area of micelles and lead to the morphological changes of ABCA tetrablock copolymer micelles. In addition, r can change the solvophobic chain conformation and hence affect the micro-structures of the solvophobic parts of the micelles. For A2B7C5A2 and A2B8C4A2 tetrablock copolymers, several novel micelle morphologies, such as the bended Janus ribbon and lamella, short Janus tube, and bowl-shaped semivesicle, are obtained. Interestingly, it is found that in the phase diagrams of A2B7C5A2 and A2B8C4A2 tetrablock copolymers, the micelle type with Janus-like solvophobic parts is the majority micelle type, which mainly results from the solvophobic interaction balance between blocks B and C. Moreover, the formation pathways for these novel Janus-type micelles are given and discussed.

We demonstrate a temperature directed morphology transformation (TDMT) process to convert spherical nanoparticles to a variety of various 3D structures, including (i.e. worms, vesicles and lamella sheets). By regulating the amount of SDS, we transformed spheres to 3D structures, which was fully reversible.

Five intercalating coordination networks consist of an identical lamella of pyridine-2,3,5,6-tetracarboxylates linking up GdIII cations, and diverse hydrated cations, which provide an interesting model to understand the metal–metal interactions.

Hydrothermal synthesis and crystal structure of a lamellar hydrated sodium zinc arsenate with an unusual sheet structure are reported.
