Ultraviolet Light (UV)-Induced Photocatalytic Degradation of Diclofenac Using Naturally Derived TiO2@rGO Composite

Lorenz E. Borromeo, Lea P. Bongat, John Patrick S. Nunez, Kirby F. Mendioro, Jocelyn R. Balisnomo
Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Utilisation of Carbon Capture and Mineralisation Products: Considering Monohydrocalcite as a Potential Functional Filler

Roneta Chaliulina
Calcium carbonates, ground and precipitated, have an established role in material engineering where they serve as fillers and pigments. In this study monohydrocalcite (MHC) was produced from artificial industrial waste brines as a means of sequestering CO2, and assessed as a potential functional filler, where its properties were compared with other minerals used in the industry. The results from the morphological analysis which compared MHC with the shapes and sizes of filler crystall...

Black Oil Sunflower Seeds in CuNP Synthesis

Annika Joshi
Black oil sunflower seeds (Helianthus annuus L) are the preferred feed for wild birds due to their high calorie content and their thin hulls. However, the oils can spoil easily in humid and hot climates resulting in wastage. Our hypothesis is that we can synthesize copper nanoparticles (CuNPs) using sunflower seeds as a reducing agent. The process used involved a solution of copper sulfate, an extract of black oil sunflower seeds, and starch as a capping agent. Visual observation showed a...

Harnessing the Solar Energy in Extracting Essential Oil for Community Based Perfumery and Aromatherapy

Agnes R. Pesimo
The study is focused on the use of solar energy in extracting essential oil as alternative process of extracting essential oil. In particular, it determined the rate of extraction and percent yield at normal temperature and weather condition. Four kinds of plant samples with known aromatic characters and pharmaceutical importance, Sambong (Conyza balsamifera Lin

Dual-Purpose Solvay-Dow (Magnesium) Conceptual Process

Hussein Abdel-Aal, Maha Abdelkreem, Khaled Zohdy
The proposed process basically combines two decades old processes (Solvay and Dow Magnesium) for the manufacture of soda ash and magnesium, respectively into a single process that also produces “partially-desalinated” water. It does so by subjecting salt brines first, to ammonia causing two simultaneous actions: 1) the absorption of ammonia forming what is called “ammoniated brine”, and 2) the precipitation of magnesium ions, foun

One-Pot Synthesis of Imidazolidine-2-Thiones, Hydantoins and Thiohydantoins under Solvent-Free and Grinding Conditions

Mohammad M. Ghanbari, Javad Safari, Zahra Roohi
A convenient, environmentally friendly and mild green synthesis of imidazolidine-2-thiones, hydantoin and thiohydantoin derivatives was developed by the one-pot reaction of benzils, urea or thiourea derivatives, and strong base at with grinding. The key advantages are the short reaction times, excellent yields, simple workup, and easy purification in the solvent-free condition. The present method aimed to overcome the limitations and drawbacks of the reported methods such as hard work-up, low yi...

Skeletally Modified Polyamide Flame Retardant Coatings

J. Sheeba Vinolia, D. Duraibabu, S. Aparna, S. Ananda Kumar
The use of polyamide coatings for electrical applications is restricted mainly because of its inadequate flame retardant behaviour. In order to improve its flame retardant behaviour, polyamide is modified by incorporating phosphorus moiety in its backbone. The structure of the phosphorus and poly amide was confirmed by infrared spectroscopy (FT-IR), NMR, thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), UL-94 vertical burning tests and char residue tests. From the resul...

Microwave Reactors: A Brief Review on Its Fundamental Aspects and Applications

Kalyan Kumar Rana, Suparna Rana
Improved laboratory protocols for convenient and rapid transformations are highly desired in modern synthetic chemistry. Microwave irradiated reactions have received considerable attention in recent years and it is a subject of intense discussion in the scientific community. Microwave heating is more efficient in terms of the energy used, produces higher temperature homogeneity and is considerably more rapid than conventional heating methods. This technique as an alternative to conventional ener...

Determination of Carbon Oxide in Exhausts of Vehicles by Thermocatalytic Method

E. Abduraxmanov,М. М. Sultanov,G. N. Daminov,S. U. Tillayev
Selective methods of thermocatalytic determination of carbon oxide and hydrocarbons in exhaust gases of vehicles are based on measurement of different thermo effects of oxidation of a combustible mixture, obtained from two identical thermosensible elements working at different temperatures are developed. At one temperature there is an oxidation of all analyzed gas mixture, and on another—the mixture without a selectively determined component and by the difference of thermo effects an exact conce...
