Potential of starch nanocomposites for biomedical applications
(IOP Publishing Ltd, 2017-06)
In recent years, the development of biodegradable materials from renewable sources based on polymeric biomaterials have grown rapidly due to increase environmental concerns and the shortage of petroleum sources. In this ...
Structural modifications of superficial layer of C45 steel samples through WT20 and WZr8 depositions
(IOP Publishing Ltd, 2017-06)
The paper presents technological aspects regarding the modification of mechanical chracteristics in the superficial layer of C45 steel samples, through thin layers deposition using WT20 and WZr8 electrodes. Deposition of ...
Influence of kaolin in fly ash based geopolymer concrete: destructive and non-destructive testing
(IOP Publishing Ltd, 2018-06)
Development of geopolymer concrete is mainly to reduce the production of ordinary Portland cement (OPC) that adverse the natural effect. Fly ash is a by-product collected from electrical generating power plant which resulted ...
Durability of fly ash based geopolymer concrete infilled with rubber crumb in seawater exposure
(IOP Publishing Ltd, 2018-06)
Geopolymer is an alternative binder to replace Ordinary Portland Cement (OPC)in construction industry. Source materials that rich in silica (Si) and alumina (Al) were activated by using alkaline solution. Production of ...
Investigation on properties and leachability of sewage sludge from wastewater treatment plant incorporated in fired clay brick
(IOP Publishing Ltd, 2018-06)
Sewage sludge is produced from wastewater treatment plant that often dumped into landfill sites, lagoons or together with municipal waste. Apart from this, the disposal of this sewage sludge becoming a problem for environment. ...
Magnetic properties of rapid cooled FeCoB based alloys produced by injection molding
(IOP Publishing Ltd, 2018-06)
The paper presents the results of investigations of the structure and magnetic properties of massive rapid cooled Fe₅₀₋ₓCo₂₀₊ₓB₂₀Cu₁Nb₉ alloys (where x = 0, 5). Massive alloys were made using the method of injecting a ...
Effect of solid to liquid ratio on heavy metal removal by geopolymer-based adsorbent
(IOP Publishing Ltd, 2018-06)
Microstructure of three-dimensional aluminosilicate which similar to zeolite cause geopolymer based adsorbent accepted in the treatment of wastewater. This paper presents an investigation on the copper removal from the ...
Geopolymers and their uses: review
(IOP Publishing Ltd, 2018-06)
Outlining the past-present history of the study of alumino-silicate materials, it is well known that geopolymers are inorganic polymers obtained from chemical reaction, also known as geopolymerisation, between an alkaline ...
The effect of baggase ash on fly ash-based geopolimer binder
(IOP Publishing Ltd, 2018-06)
Geopolymer concrete is an environmentally friendly concrete. However, the geopolymer binder has a problem with setting time; mainly the composition comprises high calcium fly ash. This study utilized bagasse ash to improve ...
Effect of mixing temperature on characteristics of thermoplastic potato starch film
(IOP Publishing Ltd, 2018-06)
This study present the preparation of potato starch film with glycerol as a plasticizer through a solution casting technique. The effect of mixing temperature (80°C, 85°C, 90°C and 95°C) on the tensile and microstructure ...
