We elucidate the effects of manganese ions infusing on the crystallographic structure and electrochemical behavior of NASICONstructured Na3+xMnxV2−x(PO4)3 (0 ≤ x ≤ 1) cathodes. The optimized structure of Na3.5Mn0.5V1.5(PO4)3/C with favorable operating voltage and high ionic diffusion capability, delivers high-rate capacity and long cycling stability, even under high-areal-loading and all-climate temperature conditions.

Surface-enhanced Raman scattering (SERS) enables rapid detection of single molecules with high specificity. The plasmonic SERS immunoassay for IgG detection showed a high linearity of SERS intensity in the range of 0.6 to 9.0 ng/mL with a detection limit (LOD) of 0.09 ng/mL, while an LOD of 0.006 ng/mL was obtained for Prostate-specific antigen (PSA).

An ultrasound-triggered ultrafast cation chelation process was developed to produce LiNi0.6Mn0.2Co0.2O2 precursor, and the whole synthesis time is only 20 min. The fabricated cathodes achieve long cycling stability (95.1% and 82.4% capacity retention for 100 and 1,000 cycles, respectively) and enable 76 s fast charging at an extremely high rate of 20 C.

In this work, we revealed that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the few-layer limit. An inplane room-temperature negative anisotropic magnetoresistance (AMR) was obtained in ultra-thin CrTe2 devices, with a sign change in the AMR at lower temperature, with −0.6% and +5% at 300 and 10 K, respectively.

Based on the enzymatic activity of horseradish peroxidase (HRP) which could induce the gradual oxidation of gold triangular nanoprisms in the presence of H2O2 and HBr as gold complexing agents, we developed a multifunctional shape-dependent plasmonic nanoprobe for detecting H2O2 and realized morphology-based logic operations and write-once plasmonic memories.

We demonstrate that two-patch silica nanoparticles are able to self-assemble side-by-side to form colloidal polymers. The colloidal chains can be assembled together to form block copolymer analogues or branched through the introduction of three-patch nanoparticles, offering a route to two-dimensional (2D) superstructures of high complexity.

Core–satellite metal–organic framework@upconversion nanoparticle superstructures are fabricated via a facile electrostatic self-assembly strategy. The resultant superstructures realize high co-loading capacity of dual photosensitizers and efficient photodynamic theranostics under 808 nm near-infrared light irradiation.

Element-selective X-ray magnetic circular dichroism (XMCD) study probes the coexistence of ferromagnetism and antiferromagnetism in two-dimension (2D) silicene and germanene coupled with rareearths. It determines the layer-dependent evolution of magnetism with applied magnetic field, magnetic polarization of the Xene backbone, spin, and angular contributions to the magnetic moments.
