This paper describes the results from ultraviolet (UV) spectroscopic studies of diamide ligands namely N,N’-2,6- bis(3-pyridylmethyl)pyridine dicarboxamide (L5) and N,N’-2,6-bis(4-pyridylmethyl)pyridine dicarboxamide (L6) towards chloride, nitrate and chromate anions in solution. The responses of the ligands towards anions are monitored by the changes of the absorbance in the UV spectra. The time interval experiments were conducted from 0 to 3 hours, resulted to the rise of the absorbance of the ligands. The change in the absorbance value is attributed to the increase of interaction between the ligands and anions that is proportional with time. In contrast to the ligands, the absorbance of anion is decreased showing the reduction of anion concentration in the solution. Rapid UV response indicates the sensitivity of these ligands towards anions which at the same time showing promising potential as sensitive anion sensor...

The study on thiourea derivatives and its coordination complexes have been well documented with majority of the synthesized compounds have high potential to be used as antibacterial agents. In line with this interest, two thiourea ligands derived from amino acids, namely 2-(3-dodecanoyl-thioureido)-3-methylbutyric acid (L1) and 2-(3- dodecanoylthioureido)-3-phenylpropionic acid (L2) have been reacted with ZnCl2 and CuCl2, to produce three new complexes with general formula of [Zn(L1)Cl2] (1), [Zn(L2)Cl2] (2) and [Cu(L2)Cl2] (3) as suggested by elemental analysis. The complexes were characterized by spectroscopic techniques such as Fourier Transform Infrared (FTIR) and Ultraviolet-Visible (UV-Vis). The antibacterial activities of the complexes were evaluated against three common Gram-positive strains (S. aureus, S. epidermidis and B. subtilis) and two Gram-negative strains (E. coli and S. typhimurium). This study revealed that complex 3 had a good antibacterial activity towards Gram-pos.....

An extremely easy method is presented for producing TiO2 nanoparticles (NPs) films as photoanode in dye-sensitized solar cell applications. This paper presents the study on the effect of Polyethylene glycol 20000 (PEG 20000) on the properties of TiO2 NPs films. The amount of PEG 20000 were varied between 0.1 and 0.5 g. Sonication and stirring of commercial TiO2 NPs Degussa P25 and PEG 20000 in ethanol results in highly homogeneous dispersions which are used to prepare TiO2 films. The use of optimum amount of PEG 20000 will increase the light absorption due to the increment of the surface area within the film. The films were characterised using ultraviolet-visible-near infrared spectrometer, field emission scanning electron microscopy and current-voltage measurement...

Snail allergy is rare, but it can lead to severe allergic reactions. Life-threatening reactions including anaphylactic shock have been often reported after snail consumption. Cerithidea obtusa is a commonly consumed sea snail in Malaysia and other Asian countries. The purpose of this study was to determine the frequency of immediate hypersensitivity reactions to this species of snail by skin prick test (SPT). Snail proteins were extracted from the snail flesh. A total of 131 patients with atopic diseases were skin prick tested with the snail extract. Out of 131 subjects, 10 (8%) were sensitized to C. obtusa extract. Most of these subjects are allergic rhinitis (70%), allergic conjunctivitis (60%), asthma (20%) and food allergic (20%) patients. As a conclusion, this study showed that the immediate hypersensitivity to marine snail, C. obtusa exists among local atopic patients at a low frequency of 8%. It seems like a patient with C. obtusa sensitization is also probably to be sensitized .....

The aim of this study is to determine the effectiveness of multi-frames video recorded experiments (MFVREs) on pre-university students’ achievement for capacitor topic. This study was carried out among 60 Diploma Science students of Universiti Pendidikan Sultan Idris, Malaysia. Students’ pre-test and post-test scores were analyzed using independent sample t-test. The effectiveness of MFVREs on students’ achievement were analyzed for four subtopics of capacitor: basic concept of capacitor (S1), series connection of capacitors (S2), parallel connection of capacitors (S3) and combination of series and parallel connection of capacitors (S4). Findings revealed that MFVREs give significant effects on students’ achievement for S2, S3 and S4 subtopics but no significant effect to students’ achievement for S1 subtopic compared to PowerPoint slides. Thus, MFVREs approach can be used either as a teaching aid in normal classroom or a student-centered learning video in order to improve th.....
