This development research aims to make a tool and test its ability to absorb the heat in light radiation by colored surfaces (black, dark green, blue, white). The benefit of this research is to present a simple laboratory that can be used in physics educa... see more

The enhancement of light absorption and photoluminescence quenching properties of the bulk heterojunction systems which were fabricated using poly(N-vinylcarbazole) (PVK); poly(N-hexylthiophene)(P3HT) and fullerene derivative 1-(3-methoxycarbonyl) propyl-... see more

We have investigated the enhancement absorption light and luminescence properties of the blend conducting polymers using poly(N-vinylcarbazole) and poly(N-hexylthiophene). The optimized material showed a broad absorption in the region of ultra violet to n... see more

In this study, we attempted to quantify light absorption by insoluble light-absorbing particles (ILAPs) such as black carbon (BC), organic carbon (OC) and iron oxides in snow using an optical method directly and compared the results with those obtained us... see more

The aim of this work is to evaluate the influence of absorption processes on the time of flight of light going through an absorbing and scattering thick medium (clouds, paints, gas cell, etc). In order to study statistical scattering and absorbing process... see more

Telah dilakukan penelitian terhadap spektrum serapan cahaya pada sampel dye yang diekstrak dari daun suji (Pleomele angustifolia N.E. Brown), buah senduduk (Melastoma malabathricum L.) dan campuran keduanya. Tujuan dari penelitian ini adalah untuk mempela... see more

This research aims to determine the effect of adding oil palm shell ash on the quality of the resulting lightweight concrete bricks. Based on SNI 03-2847-2002, lightweight concrete is concrete containing light aggregate and unit weight between 800-1900 kg... see more

Lightweight concrete has as main characteristic its low density due to the incorporation of light materials such as expanded clay, or even the incorporation of air whose function is to reduce the density, characteristic of cellular concrete. In Aracaju ci... see more

Particulate waste of bagasse, cocoa pod husk and guinea fowl feathers may be adopted to fabricate epoxy composites due to their properties of biodegradability, lightweight and cheapness. However, most research has excluded the combination of these reinfor... see more
