The development of a rapid, highly sensitive, and dependable acetone sensor holds significant importance for human health safety. To enhance the sensing performance LaFeO3 nanoparticles practical applications, commercial n-type WO3 were incorporated as additives. They directly mixed with produced through sol-gel method, creating series WO3-LFO nanocomposites varying mass ratios. These character...

It is well known that magnetic exchange coupling across the ferromagnet–antiferromagnet interface results in an unidirectional magnetic anisotropy of the ferromagnetic layer, called exchange bias. Despite large experimental and theoretical efforts, the origin of exchange bias is still controversial, mainly because detection of the interfacial magnetic structure is difficult. We have applied pho...

The ab initio calculation of quasiparticle (QP) energies is a technically and computationally challenging problem. In condensed matter physics the most widely used approach to determine QP energies is the GW approximation. Although the GW method has been widely applied to many typical semiconductors and insulators, its application to more complex compounds such as transition metal oxide perovsk...

An in-situ template formation method is reported for the synthesis of hierarchically porous carbon (PC), with La and Fe nitrates as precursors citric acid precursor. During carbonization, oxides, originated from metal nitrates, move together react each other to form LaFeO3 particles, serving hard PC. Thus, three types pores are generated in PC through (1) release gases, (2) movement oxides (3) ...
