Stabilization of Sb Tetrahedra in Paramagnetic Transition Metal Carbonyl Complexes.

We present a straightforward synthetic route to the novel chromium carbonyl-stabilized paramagnetic Sb-based cluster [EtN][SbCr(CO)] ([EtN][]), which represented a rare example of the intact Sb tetrahedron structurally characterized in the solid state. Complex exhibited versatile reactivities toward groups 7-9 metal carbonyls, dioxygen, or [Cu(MeCN)][BF] to form selective orbital-controlled Sb-based products, including transmetalated paramagnetic complexes [EtN][SbCrMn(CO)]Br ([EtN][]Br), [EtN][SbCrFe(CO)] ([EtN][]), and [EtN][SbCrCo(CO)] ([EtN][]), the dioxygen-activated paramagnetic cluster [EtN][OSbCr(CO)] ([EtN][]), or the spin-quenched complex [EtN][SbCr(CO)] ([EtN][]), respectively. The structural nature, bonding properties, paramagnetism, and semiconductivity of these unprecedented transition metal carbonyl-protected Sb-based clusters were further realized with DFT calculations.

In Situ Electrochemical Activation Strategy toward Organic Cation Preintercalated Layered Vanadium-Based Oxide Cathode for High-Performance Aqueous Zinc-Ion Batteries.

Layered vanadium-based oxides with preintercalated metal cations are attracting extensive attention as highly promising candidates for aqueous zinc-ion batteries (AZIBs) due to the increase in structural stability originating from the pillar effect. However, the strong electrostatic interaction between the rigid metal cation pillars and zinc ions results in sluggish ionic transport, thereby limiting the high-rate performance. Herein, a layered vanadium-based oxide with protonated 1,4-diaminobutane organic cation (BDA) pillars is designed as a cathode material for AZIBs.

The chitosan confined pyrolysis strategy enhances the catalytic performance of a carbon material based on a novel carboxyl functionalized MOF.

Compared with direct carbonization and physical mixing carbonization, (Co-MOF--CTS)-900 prepared by confined pyrolysis shows excellent catalytic reduction performance.

Single -crystal sodium nickel phosphate nanoparticles as supercapacitor cathodes with ultra-high capacitance and rate-performance.

Sodium nickel phosphate (NaNiPO, NNP) is an attractive cathode material for high performance supercapacitors due to its abundance of active sites for oxidation/reduction, highly stable framework structure, . However, its disadvantages of low electric conductivity, disturbances of its impure crystalline phase, and the numerous pores/gaps produced by agglomerated polycrystalline morphologies in this cathode often limit its electrochemical performance. Herein, single-crystalline NNP rod-like nanoparticles with high phase purity have been prepared by spontaneous combustion combined with subsequent solid-phase calcination.

However, the role of ILC2 in regulating sepsis-induced cardiac dysfunction and its underlying mechanism remain unknown.

Precise Control Over Crystallization Kinetics by Combining Nucleating Agents and Plasticizers for 20.1% Efficiency Organic Solar Cells.

Obtaining controllable active layer morphology plays a significant role in boosting the device performance of organic solar cells (OSCs). Herein, a quaternary strategy, which incorporates polymer donor D18-Cl and small molecule acceptor AITC into the host D18:N3, is employed to precisely modulate crystallization kinetics for favorable morphology evolution within the active layer. In situ spectroscopic measurements during film-formation demonstrate that while D18-Cl works as a nucleator to promote aggregation of D18 and foster donor/acceptor intermixing, AITC has exactly the opposite impact on aggregation of N3 and intermixing kinetics of donor and acceptor, working as a plasticizer.
