A Layered Aluminophosphate [CHN][Al(PO)]·5HO with Fluorescent Property Derived from Carbazolyl-Modified Template.

Designing and innovating organic structure-directing agents is the key to synthesizing novel molecular sieve structures. Herein, we design a novel carbazolyl-modified template and further synthesize a two-dimensional layered aluminophosphate with [CHN][Al(PO)]·5HO (denoted as ZHKU-2). ZHKU-2 is composed of AA-stacked [AlPO16] layers constructed from alternating AlO and PO(=O) tetrahedrons to form a 4.

A Mononuclear Iron(II) Spin-Crossover Molecule Decorated by Photochromic Azobenzene Group.

Aiming at constructing photoresponsive spin crossover (SCO) behavior, herein we designed a new ligand Abtz (Abtz = ()--(4-(()-phenyldiazenyl)phenyl)-1-(thiazol-4-yl)methanimine) which was decorated by a photochromic azobenzene group. Based on this photochromic ligand, a mononuclear Fe(II) SCO molecule [Fe(Abtz)](BF)·(EAC) (, EAC = ethyl acetate) was successfully synthesized and showed a complete one-step SCO behavior. Under continuous UV light and blue-light exposure, the photoisomerization of both ligand Abtz and compound in the liquid phase was confirmed through UV-Vis spectra.

Mandible reconstruction assisted by preoperative virtual surgical simulation.

Objective: In this study, we evaluated the clinical efficacy of mandible reconstruction with preoperative virtual planning, which focused on esthetics and occlusion.

Study Design: A series of 9 patients were enrolled prospectively to undergo mandibulectomy and simultaneous reconstruction. Preoperative spiral CT scans of the maxillofacial region and the fibula region were performed.

Clinical evaluation of ceramic implant abutments in anterior restorations.

The development of new high strength ceramic abutments can enhance the overall aesthetic outcome of an implant-supported prosthesis. This study was to compare the clinical application of alumina and zirconia ceramic implant abutments in the anterior region. Twenty-three consecutive patients requiring single-tooth implants in the anterior region were randomized to receive either an alumina ceramic abutment (CeraAdapt) or a zirconia ceramic abutment.

[Maxilla reconstruction with the free iliac osteomuscular flap and simultaneous osseointegrated implant embeding].

Objective: To evaluate the clinical outcome of reconstruction of maxillary defects with vascularized iliac crest flap and simultaneous osseointegrated implant embedding.

Methods: During September to October 2003, two patients with maxillary defects from tumor resection underwent microsurgical reconstruction. The free iliac osteomuscular flap transferring and simultaneous osseointegrated implant embedding were performed to repair the defects.
