Abstract Potassium‐ion batteries (PIBs), using carbon materials as the anode, are regarded a promising alternative to lithium‐ion owing feasible formation of stage‐1 potassium intercalation compounds (KC 8 ). However, due large radius ion, graphite‐based electrodes still suffer poor rate capability and insufficient cycling life. In this work, hierarchically nitrogen‐doped porous (NPC) is reported for first time. The NPC electrode delivers high reversible capacity 384.2 mAh g −1 after 500...
Rechargeable aqueous Zn-ion batteries are promising candidates for large-scale energy storage systems. However, there many unresolved problems in commercial Zn foils such as dendrite growth and structural collapse. Herein, Cu mesh modified with CuO nanowires is constructed to simultaneously coordinate the ion distribution electric field during nucleation growth. Owing improved uniformity of plating confined 3D framework, prepared anodes can be operated steadily symmetrical cells 340 h a low...
Doping Li + resulted in oxygen vacancies and green-yellow emission. Changing the excitation wavelength/temperature yielded varied visible/NIR lights afterglows, which contributed to a dynamic luminescence.
Doping Li + /Ga 3+ in ZnGa 2 O 4 :Cr splits the energy level of electron traps into shallow and deep traps, which makes developed phosphors be successfully excited by a low-energy NIR light suitable for long-term biological imaging.
Activating multielectron reactions of sodium superionic conductor (NASICON)-type cathodes toward higher energy density remains imperative to boost their application feasibility. However, multisodium storage with high stability is difficult achieve due the sluggish reaction kinetics, irreversible phase transitions, and negative structural degradation. Herein, a kind NASICON-type Na2.5V1.5Ti0.5(PO4)3/C (NVTP-0.5) hierarchical microsphere consisting abundant primary nanoparticles designed,...

This minireview summarizes and highlights the recent advances investigations on defect engineering of molybdenum disulfide, with a special focus applications in lithium-, sodium- potassium-ion batteries.
Although silicon is being researched as one of the most promising anode materials for future generation lithium-ion batteries owing to its greater theoretical capacity (3579 mAh g-1), practical applicability hampered by worse rate properties and poor cycle performance. Herein, a silicon/graphite/amorphous carbon (Si/G/C) composite material has been successfully prepared facile spray-drying method followed heating treatment, exhibiting excellent electrochemical performance compared with...
The structure of a single crystal dehydrated zeolite Na−X selected from batch grown by Petranovskii in Russia, composition Na92Si100Al92O384 per unit cell, was determined X-ray diffraction methods the cubic space group Fd3̄; = 25.077(4) Å at 21 °C. R1 0.054 for 320 reflections which Fo > 4σ(Fo); wR2 based on F2 and all data is 0.140. Na+ ions are found four crystallographic sites. Sites I' II fully occupied with 32 each. remaining 28 partially occupy two 12-ring (site III') positions 10(4)...
Modern engineering fields put forward requirements for optical temperature sensors, which need natural-light excitation/storage and near-infrared (NIR) afterglow emission some special conditions. Here, NIR persistent luminescent phosphors of ZnGa2–x(Mg/Ge)xO4:Cr3+ (x = 0–1.25) have been synthesized. The incorporation Mg2+/Ge4+ ions in ZnGa2O4:Cr3+ resulted more defect clusters "MgGa′–GeGa•" "ZnGa′–GeGa•" interstitial oxygens (OInt). Increasing the calcination doping both contributed to...

Ortho-carboxyl-substitution increases the acidity of hypervalent diaryliodonium salts and makes them useful catalysts in synthesis bis(indolyl)methanes under mild conditions, with yields up to 98%. The halogen bond-assisted hydrogen bonding was demonstrated by crystal structure analysis. interaction distance 2.619 Å between I(III) carboxyl O atom indicates either a long covalent or very short bond; analysis electron density shows latter description is appropriate.
Enterprises with good long-term free cash flow data often have better prospects than enterprises net profit but unstable for a long time, and prediction is an important part of evaluating the enterprise value enterprise. By determining fitness function, algorithm formula, population, Backpropagation (BP) neural network design, BP model based on improved genetic proposed to predict enterprises.
