Together with my partner, Pablo Solis, we demonstrate the particle-like nature of light as characterized by photons with quantized and distinct energies each dependent only on its frequency (ν) and scaled by Planck’s constant (h). Using data obtained through the bombardment of an alkali metal surface (in our case, potassium) by light of varying frequencies, we calculate Planck’s constant, h to ...

The iron selenide compound BaFe2Se3 was synthesized by a two-step high-temperature solid state method. The single-crystal X-ray determination of the prepared compound revealed a three-dimensional structure consisting of double chains of edge-sharing FeSe4 tetrahedra separated by Ba . In contrast to the case for alkali metal intercalated iron-based chalcogenides (like KxFe2 ySe2), the double cha...

The application of electric arc furnace ladle slag (EAF slag) in cement products might be limited due to the volume expansion and instability created by late hydration. Proper control technique should developed before reuse (LS). With addition aluminum powder alkali-activated pastes, porous materials were produced. By adjusting activator modulus between 1.25 2.00, fine pores produced foamed mat...

The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike soft handle to the po...

The use of ordinary Portland cement (PC) as the principal binder in concrete brings with it significant environmental challenges through consumption fossil fuels and emission carbon dioxide (CO2) during production. Concrete specimens made an alkali activated cementitious material (AACM) produced from alternative conventional were exposed to corrosion inducing environments for 1750 days monitor ...

At the past, damaged tissue was removed from the body of patients. But now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. Besides of the mechanical properties of metallic biomaterials, they suffer from bioinertness. Using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. In...

Abstract This study investigated the efficiency of CO 2 curing in blast-furnace slag pastes activated with three concentrations KOH solution (3, 4, and 5 M). The was applied into alkali-activated paste for 3 days. -cured were subjected to subsequent a water bath or exposed seawater. mechanical properties characteristics reaction products compared. Full strength can be obtained within days early...

Metakaolin (MK) prepared by the calcination of kaolin at 550 °C and fly ash (FA) from combustion black coal in a granulating boiler were used to prepare unfired ceramic bonding systems via alkali activation process. A long-term stability mechanical properties samples similar was observed. The optimal metakaolin ratio, type activator (NaOH or water glass) its concentration evaluated after hydrat...
