Preoxidation is an effective strategy to inhibit the graphitization of coals during carbonization. However, single effect traditional preoxidation could barely increase surface-active sites, hindering further enhancement sodium storage. Herein, a multieffect was proposed suppress structural rearrangement and create abundant sites. Mg(NO3)2·6H2O helps introduce oxygen-containing functional groups into bituminous coal at 450 °C, which acted as cross-linking agent carbon layers promote...
Thermomechanical behavior has an important effect on reliability and lifetime of high-power diode lasers (HPDLs). Finite-element analysis (FEA) model analytical solution the conduction-cooled package (CS) HPDL are established to analyze thermomechanical including normal stress, shearing displacement in reflowing process working process. Moreover, order simulate total process, thermal stress considered as residual initial condition We find that is origin other due coefficient expansion (CTE)...
High power diode lasers (HPDLs) have been applied in more and fields, such as material processing, pumping of solid-state fiber lasers, medical therapy. With the improvement output power, efficiency reliability, thermal management has one most critical issue for HPDLs. The junction temperature a laser package effects on characteristics, affecting wavelength, threshold current, slope efficiency, operating lifetime. Lower is an effective means to achieve high electrooptical conversion lasers....
