Last few decades demand for renewable energy has increased. Among those resources, biomass is widely used to produce energy as it renewable and low-cost material. Therefore, it has led to the accumulation of industrial ...
Energy consumption is a critical factor in building design. Maintaining a comfortable
indoor temperature consumes high energy than other necessities such as lighting and
cooking. The building envelope is the main component ...
A feasible process to synthesize porous graphene with ultra-high surface area is
presented in this thesis. Graphene oxide (GO) was synthesized from Sri Lankan
graphite via the modified hummers method. Then, GO was ...
In the Sri Lankan cement market present time blended hydraulic cement which is composited with fly ash or blast furnace slag are given a noticeable marketing share as supplementary cement. It has obtained more popularity ...
Sulfide stress corrosion (SSC) is a deleterious type of corrosion that is abundant in
petroleum refineries. SSC easily attacks oil country tubular goods (OCTG) in petroleum
refineries. The main factors that affect SSC ...
The improvement of mechanical properties of heat-treated (T6) Aluminium 6063
alloy is caused due to hindrance of the dislocation line by the precipitates which is
formed during the heat treatment process. The perception ...
The lubricating oil analysis is the most common method to identify the condition of any machinery. There are various ways to analyze lubricating oil, and those methods are based on an individual examination of lubricant ...
Hybrid Organic-Inorganic Perovskites (HOIP) have been studied extensively and grown popular. Especially in Three-dimensional (3D) Perovskites, achieving power conversion efficiency (PCE) exceeds 23%. Nevertheless, some of ...

The Bell 412 helicopter is a type of aircraft in the Sri Lanka Air Force (SLAF) inventory which is accorded specialty status due to its role in the transportation of VVIPs in Sri Lanka. Over three decades of operation, the ...
Cotton is a natural staple fiber that almost consist with cellulose compared to wood. The major economic value of the cotton is in Textile Industry. In the past recent years, cotton consumption demand was increased than ...
The main focus of this investigation was to add value to high purity Sri Lankan graphite. Reduced graphene oxide(rGO) was synthesized using locally available graphite from Kahatagaha mines and purity was recorded as 99%. ...
Sustainable development in concrete industries is reducing the cement consumption in overall the world. Huge amount of carbon dioxide gas is released to the atmosphere during the production time of Portland cement. Carbon ...
Cellulose has become a wonder material in the present context of research and development since it is fibrous and tough, hence biodegradable, biocompatible, and renewable natural polymer. Nowadays, rice straw as a cellulose ...
In metallurgical engineering, corrosion is considered as one of the main reasons for the failure of metallic components. The main reason for this is that, the corrosion is a phenomenon which is mainly influenced by the ...
The effect of the carbon black (CB) and graphene oxide (GO) on the mechanical properties
and microstructure of cement mortar composite were studied by preparing CB-cement
composite (CBCC) and GO-cement composite (GOCC) ...
Polyethylene waste products, especially thin polyethylene bag wastes have become a global problem in Environment Pollution Control Management. The primary objective of this project was to manufacture a property improved ...
Hybrid organic-inorganic metal halide based perovskite solar cells (PSCs) lie at the heart of the emerging technologies of the solar cells due to their ability to increase the cell efficiencies dramatically over the last ...
Corrosion is defined as the deterioration of materials due to the reaction with its
environment. According to the physical nature of environment, corrosion can be
categorized as 'corrosion in atmosphere', 'corrosion in ...
