اِس میں تیرا قصور بھی کیا ہے
مجھ کو تجھ سے پیار ہُوا ہے
خود ہی اپنا بُرا کیا ہے
تجھ کو کب الزام دیا ہے
تجھ کو کوئی افسوس نہیں کیا
میں نے خود کو مار لیا ہے
چاند کو جب بھی دیکھتا ہوں میں
دھیان میں پھر تُو آجاتا ہے
تیور تیرے بدلے بدلے
جانے تُو کیا سوچ رہا ہے
موم کی مورت ، چاند سی صورت
جانے دل کیوں پتھر سا ہے
تیری مجبوری سمجھی ہے
شکوہ تجھ سے کس نے کیا ہے
تیری ساری باتیں سچی
میں نے ہی سب جھوٹ کہا ہے
ہجر کا درد اُٹھا کر کوئی
گور کنارے اب پہنچا ہے
This study aims to find out: (1) students’ perceptions toward bilingual education in ICP (International Class Program) toward the use of two languages of instructions (English and Indonesian) by the lecturer in classroom. (2) to investigate its benefit for students in ICP chemistry education. The researcher adopted a descriptive qualitative research with a case study method. To gain the data, the researcher employed questionnaire with the students. The subjects in this study were 24 of students sixth semester belong to the International Class Program (ICP) chemistry education in State University of Makassar. The results of this study showed that there were the bilingual education helps the students to gain control their English skill. It showed that students’ positive perceptions toward the use of bilingual language as language instruction in the classroom by the lecturer. It is concluded that teaching chemistry in English facilitates the learners’ attempt in learning English.
Coordination polymers (CPs) have gained a great deal of attention because of their intriguing structures, beneficial uses in catalysis, drug-delivery, gas storage and separation etc. Four new CPs; CP-1 = [{CuII(4,4ʹ-dipy)2}{Ni(CN)4}]n·0.7(C2H6O2).1.6(H2O), CP-2 = [{NiII(4,4ʹdipy)4}{Ni(CN)4}]n·(4,4ʹ-dipy)·3H2O·C2H6O2, CP-3 = [Co3(pyz)(fa)3(dmso)2]n.2H2O and CP-4 = [{ZnII(4,4ʹ-dipy)2{Ni(CN)4}]n have been synthesized and fully characterized via range of analytical techniques. Two compounds, CP-1 and CP-2 were used as co-catalyst in combination with titania (TiO2) as efficient UV active photocatalysts for hydrogen generation from water-alcohol mixtures. Amongst different wt. % (2.5%, 5%, 7.5% and 10%) loading of CP-1 and CP-2 on TiO2, the 5 wt. % CP-1/TiO2 and CP-2 /TiO2 composites displayed the hydrogen production rate of 9.2 mmol h-1 g-1 and 11.2 mmol h-1 g-1, respectively in 5 vol. % glycerol/water mixture. Other two compounds, i.e. CP-3 and CP-4 were implied as electrocatalysts for water oxidation reaction (WOR). CP-3 executed excellent oxygen evolution reaction (OER) performance at neutral pH by producing a current density of 10 mA cm−2 at a relatively low over-potential value (η = 337 mV) with a Tafel slope value of 80.5 mV dec-1. These results are superior than previously reported cobalt based CPs. Whilst, CP-4 offered a turn over frequency (TOF) value of 0.25 s-1 at an over-potential of 324 mV (vs. RHE) which is far superior than those reported for similar cyanide bridged CPs. In addition, CP-1 was used as a single source precursor of Cu-Ni nanoparticles dispersed over TiO2 for photocatalytic hydrogen production. Amongst various synthesized photocatalysts, 1 wt. % Cu-Ni/TiO2-470 showed the maximum H2 production activity of 8.5 mmol h-1 g-1 in 20 vol. % glycerol-water mixtures. Development of some cost-effective catalysts is the key finding of this study.
