Slope of Dry Granular Materials Surface is Generally Curved
Fathan Akbar, Elfi Yuliza, Nadya Amalia +2
As if it has become a consensus that the slope of the granular heap is straight, and from that, an angle of repose is defined. However, closer inspection shows that the slopes are…
How a Snake Can Raise its Neck High although its Body is Very Soft. Similarity with a Thin Plastic Tube Filled with Air
Handika Dany Rahmayanti, DesyanaOlenka Margaretta, Nadya Amalia +5
The bodies of snakes, such as king cobras, are very soft so that it is nearly impossible for them to raise their heads higher than around one meter. By direct measurement, we were…
Stability of Granular Tunnel
Elfi Yuliza, Nadya Amalia, Handika Dany Rahmayanti +4
We demonstrated the stability of tunnels made of granular matters is strongly dependent on the grain size, tunnel diameter, and water content in the granules. Larger tunnel radius,…
New Design of Potentially Low-cost Solar Cells Using TiO2/Graphite Composite as Photon Absorber
Dui Yanto Rahman, Mamat Rokhmat, Elfi Yuliza +2
A solar cell design using the combination of titanium dioxide and graphite as active photon absorbing materials were proposed. The titanium dioxide absorbs photons of nearly ultrav…
Theoretical and Experimental Studies on a Cylinder Containing Granules Rolling Down an Inclined Plane
Edy Wibowo, Sutisna, Mamat Rokhmat +3
The dynamics of a hollow cylinder containing granules and rolling down an inclined plane was investigated. A theoretical approach for investigating the behaviour of such a cylinder…
