Self-assembled bilayer for perovskite solar cells with improved tolerance against thermal stresses To improve the tolerance of perovskite solar cells against high temperatures and temperature variations, Dong et al. covalently cross-link two molecules in the charge transport layer to strengthen adhesion wi...
Herein, single-crystalline LiMn2O4 with Eu3+ doping is rationally designed to mitigate the detri- mental Jahn-Teller distortion by tuning the chemical environment of MnO6 octahedra and accommodat-ing localized electron, based on the unique aspheric flexible 4f electron orbit of rare-earth ...
First-principle calculations were employed to study the mechanism of the electrochemical performance improvement of NiON WS. This study demonstrates the potential of transition metal oxides electrode with high capacity and activity for electrochemical energy storage and conversion. FeCo alloy/N, S dual-...

energy include the digestion of food to give energy to humans, the burning of fossil fuels, and the use of electricity to power a light bulb. A rise in world energy consumption is highly correlated with growth in the world economy. Falling energy consumption is associated with ec...
In the paper, we discuss the development of the multigap resistive plate chamber time-of-flight (TOF) technology and the production of the solenoidal tracker at RHIC (STAR) TOF detector in China at the beginning of the twenty-first century. Subsequently, recent experimental results from the fir...
18-7. He found the energy of an electron in the orbit labeled by n to be (18-9)ξn=−2π2K2me4h2.1n2 n=1,2,3,… The total energy ξn is negative because we choose the zero energy condition to correspond to infinite separation between the electron and the nucleus–that is,...
Energy demands have led states to war and are still a bone of contention between several countries. Insufficient power (power ) distribution is just one of the chief reasons for unsuccessful markets. Strong … Read More Buying A Car: What to Check and What to Consider With all the car ...
TCNQ dimers form during the first electron injection upon lithiation and followed by the break-down of the dimers and associated electron coupling to produce massive delocalized electrons, resulting in increased EPR signal during the 2nd electron injection. Reversible trends are observed during electron ...
This represents the largest systematic study of AuNC sensi- tization with different classes of donor. Moreover, AuNC sensitization by the QDs and Tb(chelate) are the first descriptions of this type of phenomena for those particular materials in this ET configuration. Experimental data is then ...
