Steam Activated Carbon Material from the Fruit Shells of Sterculia foetida for Energy and Environmental Applications
Abstract: Steam activation of the biochar from Sterculia foetida forms a green route for the synthesis of activated carbon material with high specific surface area (1017 m2/g). The corresponding value with a chemical activating agent (K2CO3) is much lower (596 m2/g). Structural parameters of the activated carbon materials were deduced from XRD studies. Moreover the thermal stability of the activated carbon materials from steam activation is nearly 100°C higher than that …

Simulation and Study of Asynchronous Pacemaker via MatLab
Abstract: A pacemaker is an electronic device, which is used by heart patients when they suffer from arrhythmias. The sinoatrial node (SA node) of our heart generates electrical impulses which travel downs the atrioventricular (AV) node to the bundle of His and then to the Purkinje fibres, from where it distributes to the ventricular region. Importance of this impulse is that it makes the heart contract, which helps in maintaining blood …
