Facile synthesis of MoO/CaSO composites as highly efficient adsorbents for congo red and rhodamine B.

A novel rod-shaped MoO/CaSO composite was prepared by using hexa-ammonium molybdate and flue gas desulfurization gypsum a simple mixed-solvothermal route. In this composite, CaSO matrices are decorated with MoO nanoparticles, and non-structural mesopores are formed particle packing. Moreover, it displays an excellent adsorption capability towards anionic congo red (CR) and cationic rhodamine B (RhB).

Self-assembled metallogels formed from N,N',N''-tris(4-pyridyl)trimesic amide in aqueous solution induced by Fe(III)/Fe(II) ions.

In this work, we report self-assembled metallogels formed from a ligand of trimesic amide, N,N',N''-tris(4-pyridyl)trimesic amide (TPTA), induced by Fe(III)/Fe(II) ions. TPTA is difficult to dissolve in water even in the presence of some metal ions such as Cu(2+), Co(2+), Ni(2+), K(+), Na(+) and Mg(2+) under heating, and it exhibits no gelation ability. Interestingly, upon heating TPTA can be dissolved easily in aqueous solution containing Fe(3+)/Fe(2+), and subsequently self-assembled into metallogels after cooling.

A microporous hydrogen-bonded organic framework: exceptional stability and highly selective adsorption of gas and liquid.

An extremely stable hydrogen-bonded organic framework, HOF-8, was fabricated. HOF-8 is not only thermally stable but also stable in water and common organic solvents. More interestingly, desolvated HOF-8 exhibits high CO2 adsorption as well as highly selective CO2 and C6H6 adsorption at ambient temperature.

[Laparoscopic abdominoperineal resection for low rectal cancer].

Objective: To assess the advantage and disadvantage of laparoscopic abdomino-perineal resection and open abdominoperineal resection for low rectal cancer.

Methods: Patients with low rectal cancer, collected from July 2003 to April 2006, were randomly divided into laparoscopic abdominoperineal resection group (37 cases) and open abdominoperineal resection group (37 cases). Operation time, number of lymph node removed, intra-operative blood loss, time to pass flatus, time to ambulate, time to discharge, complications, early recurrence, and economical cost were compared between the 2 groups.

[One stage thyroidectomy and bilateral neck dissection for well-differentiated thyroid carcinoma].

Objective: To investigate the indications, safety and difficulties of one stage thyroidectomy and bilateral neck lymph node dissection for well-differentiated thyroid carcinoma.

Methods: A retrospective review was carried out in 36 well-differentiated thyroid carcinoma patients so treated from 1990 to 2004. Various incisions including H, L and modified Kocher types were selected according to the location of primary tumor and status of cervical lymph node metastasis.
