This study examined the impact of dielectric heating at radio frequencies (RF) as a pre-treatment on the kiln drying characteristics and end-quality of sub-alpine fir that is difficult to dry due to significant amount of wet pockets. Five plus a control group of 51×102 mm sub-alpine fir were RF heated at fixed power density (72 kW/m3), to the same core(More)
The conversion of solar energy into hydrogen fuel by splitting water into photoelectrochemical cells (PEC) is an appealing strategy to store energy and minimize the extensive use of fossil fuels. The key requirement for efficient water splitting is producing a large band bending (photovoltage) at the semiconductor to improve the separation of the(More)
The goal of this work was to investigate the relevant dosimetric and luminescent properties of MgO:Li3%,Ce0.03%,Sm0.03%, a newly-developed, high sensitivity Optically Stimulated Luminescence (OSL) material of low effective atomic number (Zeff = 10.8) and potential interest for medical and personal dosimetry. We characterized the thermoluminescence (TL),(More)
This study aimed to investigate the changes of internal moisture content distribution within hem-fir timbers after kiln drying while exposed to two different local outdoors seasonal conditions. Timbers were dried to three different target moisture contents (12, 17, and 22 %) and thereafter, they were conditioned outdoors in two diverse seasonal coastal(More)
