April 2020: A thermodynamic database for the Ca2+ // Cl–, ClO4– – H2O system has been developed recently. The model can be used for simulating the phase equilibrium behavior in calcium, chloride and perchlorate system with implication for constraining the fractionation of ClO4– and the ratio of ClO4–/Cl–. This database was given a name of CaClO4Cl-G.db, in which all the standard thermodynamic parameters and ion-interaction parameters are included. This database is compatible with ISLEC version 4.2. To have a test on the model, please visit to the ISLEC-Web-Ca-Cl-ClO4. Any suggestion and bug report can be send to ddong_li@hotmail.com.
December 2018: A thermodynamic database for the Mg2+ // Cl–, ClO4– – H2O system has been developed recently. The model can be used for simulating the phase equilibrium behavior in magnesium, chloride and perchlorate system with implication for constraining the fractionation of ClO4– and the ratio of ClO4–/Cl–. This database was given a name of MgClO4Cl-G.db, in which all the standard thermodynamic parameters and ion-interaction parameters are included. This database is compatible with ISLEC version 4.2. To have a test on the model, please visit to the ISLEC-Web-Mg-Cl-ClO4. Any suggestion and bug report can be send to ddong_li@hotmail.com.
December 2018: A thermodynamic database for the Mg2+ // OH–, SO4– – H2O system has been developed recently. The model can be used for simulating the phase equilibrium behavior of magnesium, hydroxide and sulfate system with implication for magnesium oxsulfate (MOS) cement material preparation. This database was given a name of MOS-G.db, in which all the standard thermodynamic parameters and ion-interaction parameters are included. This database is compatible with ISLEC version 4.2. To have a test on the NEW MODEL, please visit to the ISLEC-Web-MOS.(2018年12月：氢氧化镁+硫酸镁+水体系多温热力学模型开发完成，并集成于本平台。利用该模型可以实现该三元体系相平衡和热力学性质的模拟，用以指导硫氧镁水泥材料的设计。该模型相关工作已经发表于CALPHAD杂志，2019, 67, 101675.

October 2015: The ISLEC-Web based on ISLEC version 4.1 and used the parameter database SLBM-G.db is online. The model or software applications have been updated. (2015年10月：ISLEC-Web上线，实现在线计算。同时更新了模型和软件。)
June 2015: The new offical website of ISLEC is online! This website is an improved version of our previous website constructed since 2012 with the same domain www.islec.net. The previous versions of the ISLEC software are all based on the Pitzer ion interaction model instead of the present Pitzer-Simonson-Clegg can be found on Sourceforge. You can click to download old versions.(2015年6月：新的ISLEC官方网站上线。本网站是之前我们2012年发布的ISLEC网站的升级版本，但仍然沿用之前的域名www.islec.net不变。)
