The effect of carbonization temperature, carbonization time and impregnation ratio on the properties of activated carbon produced from Arundo donax
(Elsevier Science Bv, 2018)
Activated carbons from Arundo donax were obtained by varying impregnation ratio, carbonization time, and carbonization temperature via chemical activation method. By operating impregnation ratio as 1.5 and carbonization ...

The study aims to investigate the influence of inter-organizational knowledge sharing enablers-communication, trust, shared vision, commitment, learning intent, and absorptive capacity directly and indirectly through ...
The The validity of Kohlrausch law for the photocurrent transient and the role of N-2/Ar flow ratio in photoconductivity of sputtered CoZnO
(Elsevier Science Sa, 2017)
Co:ZnO (CZnO) ferromagnetic semiconductor layers are coated on the surface of glass and Si substrates by Magnetron Sputter Deposition Method (MSDM) with variable N-2/Ar gas flow ratio. N-2/Ar flow ratio varies from 5 sccm ...
Polymer coated pumice aggregates and their properties
(Elsevier Sci Ltd, 2014)
Pumices which are preferred due to their properties such as low unit weight, heat insulation property, resistance against fire were combined with polymer, the material of our age, to produce light concrete aggregate. In ...
An activity based on an inquiry-driven creative drama: stray animals need some shade
(Routledge Journals, Taylor & Francis Ltd, 2021)
This study aimed to develop, introduce, and conduct an inquiry-driven creative drama activity. The activity, for elementary students, related to the transmission of light and full shadow. In the activity, which consisted ...
Synthesis, characterization and comparative studies on the photophysical and photochemical properties of metal-free and zinc(II) phthalocyanines with phenyloxyacetic acid functionalities
(Pergamon-Elsevier Science Ltd, 2011)
The synthesis and characterization of new peripherally and non-peripherally tetra-substituted metal-free and zinc(II) phthalocyanines with 2-, 3- and 4-phenyloxyacetic acid functionalities are described for the first time ...
Modelling of dynamic cutting force coefficients and chatter stability dependent on shear angle oscillation
(Springer London Ltd, 2017)
Productivity of high-speed turning operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting tool ...
