Parasitic absorption by window layer, electrode and interface layer in the near ultraviolet (UV) region is no longer negligible for high-efficiency perovskite solar cells. On other hand, UV-induced degradation also a big component of cell instability. Herein, CsPbCl3:Mn-based quantum dots (QDs) are synthesized applied onto front side cells as energy-down-shift (EDS) layer. It found that with very high yield (∼60%) larger Stokes shift (>200 nm), CsPbCl3:Mn QDs effectively convert normally...
Synthetic high-performance fibers present excellent mechanical properties and promising applications in the impact protection field. However, fabricating with high strength toughness is challenging due to their intrinsic conflicts. Herein, we report a simultaneous improvement strength, toughness, modulus of heterocyclic aramid by 26%, 66%, 13%, respectively, via polymerizing small amount (0.05 wt%) short aminated single-walled carbon nanotubes (SWNTs), achieving tensile 6.44 ± 0.11 GPa,...
Investigating lightweight electromagnetic microwave absorption materials is still urgent because of the issue related to pollution or military defense. Our findings indicate that core–shell MnO@carbon nanowires (MnO@C NWs) achieve substantially enhanced absorption, suggesting suitable impedance matching induced by synergetic effect between MnO and carbon. Furthermore, peapod-like MnO@C NWs with internal void space can be facially synthesized partial etching NWs. The voids/cavities exhibit...
Abstract Owing to the development of electronic devices moving toward high power density, miniaturization, and multifunction, research on thermal interface materials (TIMs) is become increasingly significant. Graphene regarded as most promising management material owing its ultrahigh in‐plane conductivity. However, fabrication high‐quality vertical graphene (VG) arrays their utilization in TIMs still remains a big challenge. In this study, rational approach developed for growing VG using an...
Fully transparent ultraviolet photodetectors (PDs) based on the CsPbCl<sub>3</sub> nanocrystals (NCs) were fabricated for first time.
Lateral heterostructures with planar integrity form the basis of two-dimensional (2D) electronics and optoelectronics. Here we report that, through a two-step chemical vapor deposition (CVD) process, high-quality lateral can be constructed between metallic semiconducting transition metal disulfide (TMD) layers. Instead edge epitaxy, polycrystalline monolayer MoS2 in such junctions was revealed to nucleate from vertices multilayered VS2 crystals, creating one-dimensional ultralow contact...
Abstract Poly(p‐phenylene‐benzimidazole‐terephthalamide) (PBIA) fibers with excellent mechanical properties are widely used in fields that require impact‐resistant materials such as ballistic protection and aerospace. The introduction of heterocycles polymer chains increases their flexibility makes it easier to optimize the fiber structure. However, inadequate orientation is one main reasons for large difference between measured theoretical PBIA fibers. Herein, carbon nanotubes (CNTs)...

Homogeneous graphene dispersions with tunable concentrations are fundamental prerequisites for the preparation of graphene-based materials. Here, a strategy effectively dispersing using oxide (GO) to produce homogeneous, tunable, and ultrahigh concentration (>150 mg mL-1 ) is proposed. The structure GO abundant edge-bound hydrophilic carboxyl groups in-plane hydrophobic π-conjugated domains allows it function as special "surfactant" that enables dispersion. In acidic solutions, sheets tend...
Abstract Finding the best applications of graphene, and continuous scalable preparation graphene with high quality purity, are still two major challenges.

The obtained exhibits small size (≈180 nm), quality, low oxygen content, together gas–solid conversion efficiency ≈10.46%. Considering intrinsic...
