The N-doped porous carbon monoliths prepared by direct carbonization of IRMOF-3, through an in situ activation and self-templating process, were found to exhibit significantly enhanced performance for the selective adsorption of CO2 compared to pristine IRMOF-3. The transformation from the microporous structure to the meso-macroporous structure opens the pathway for CO2 to more easily access the nitrogen anchors.

A new kind of supramolecular organogel system based on dicarboxylic acids and primary alkyl amines (R–NH2) was obtained, in which the aggregation morphology of gelators could be controlled by solvent polarity and tail chain length.

Supramolecular hydrogels with solution–gel–crystal transition, pH- and thermo-reversible characteristics were constructed via a solvent-mediated strategy and applied to cell cultivation and controllable drug release.

Currently, the design and construction of an intelligent stimuli-responsive gel system is still a significant challenge. We present here a new gel system from which the formation of heat-set gels, conventional gels and irreversible heat-set gels can be achieved in aromatic solvents. This gel system is based on two-component gelators containing a succinamic acid derivative (SAD) and a primary alkyl amine (R-NH2). With the increase of temperature to 85 °C, a rarely reported reversible heat-set gel (gel formation with the increase of temperature) is afforded. Upon addition of fatty acids into two-component gelators, a conventional gel (gel formation with the decrease of temperature) is formed. When the fatty acid is replaced with dicarboxylic acid, a new heat-set gel is generated, which is irreversible and thermally super-stable. X-ray diffraction analysis reveals that the formation of a reversible heat-set gel relies on electrostatic interactions, hydrogen bonds, and hydrophobic interactions. These two-component gelators show a perfect gel system for the formation of diverse gels including heat-set gels, conventional gels and irreversible heat-set gels. The tunable strategy demonstrated in this letter may provide a new way for creation of more functional gels in gel science.

A rare (3,4,5)-connected self-interpenetrated metal-organic framework with an O-atom lined pore surface has been constructed from Zn(II) and H4L (H4L = 5,5'-(1,3,6,8-tetraoxobenzo[lmn][3,8]phenanthroline-2,7(1H,3H,6H,8H)diyl)-diisophthalic acid), which features an unprecedented 1D + 2D → 3D self-interpenetrated array and shows good controlled drug release properties.

Ultrasound-induced gelation of a novel type of gelator, 1,4-naphthalenedicarbonyl- dinicotinic acid hydrazide, is reported. The gelator self-assembled into various architectures in different solvents.

Background and purpose: Maxillary and cheek reconstruction is one of the most challenging tasks for surgeons. The purpose of this study was to assess the clinical application and therapeutic efficacy of the maxillary and the through and through cheek defects reconstructed with titanium mesh and folded free anterolateral thigh flap. Materials and methods:Between October 2010 and May 2013, 16 patients were treated for maxillary reconstruction with titanium mesh and folded free anterolateral thigh flap at Sun Yat-Sen University Cancer Center. Intra-operatively, the titanium mesh was fixed to the residual bones for the reconstruction of hard-tissue defects after tumor resection; then the anterolateral thigh flap was harvested and folded to repair the through and through cheek defects, serving as the intraoral lining and titanium mesh covering.Result: Apart from one total flap loss, 15 of the 16 free ALT flaps survived. All of the patients achieved a satisfactory facial appearance. No major complications or donor site morbidity occurred. Conclusion:Reconstruction of maxillectomy defects and the through and through cheek defects using titanium mesh in combination with folded free anterolateral thigh flap is a feasible and acceptable option.
