Here, we report a lattice-confined approach to concurrently enhance the stability and intrinsic activity of Ru via confining ultrafine Ru clusters into TiO 2 lattice frameworks. Impressively, such confined Ru delivers outstanding performance for HER under harsh conditions, such as a small overpotenital of 116 mV at 800 mA cm −2, and long ...

The development of high energy-density Ni-rich (Ni ≥ 90%) layered cathodes has remained difficult because of the rapid capacity fading that occurs during cycling. This study demonstrates that limiting the primary particle size of the cathode resolves the capacity fading problem as nano-sized primary particle

Rectification. Rectification is a form of fractioning, coarser than fractional distillation, that separates the odor molecules of an essential oil that have very different boiling temperatures. The odorant compounds of the essential oil pass one after the other into the distillation column and are collected separately, after condensation.
Strong, electroactive and ultrafine conducting polymer fibres are prepared at the large scale by a modified wet spinning strategy. The obtained ultrafine polyaniline fibres are qualified to …
The as-cast ingot exhibits excellent castability without obvious shrinkage cavity and other casting defects as shown in Fig. 1a.To verify the microstructure homogeneity across the length of the ingot, the cross sections from the top region (Fig. 1b–c) and the bottom region (Fig. 1d–e) were examined.Both cross sections regular eutectic cell structure with ultrafine lamellar …
A Co/CoO@NC hybrid material with high specific surface area and ultrafine particle size was prepared using a novel Co-MOF as a sacrificial template. The Co/CoO@NC shows excellent performance in the catalytic reduction of 4-nitrophenol (4-NP) and recyclability, the reaction rate constant k = 0.0139 s −1 (0.2 mg, 298 K) is better than some reported precious metal catalysts.

Aerosol-cloud interactions remain the largest uncertainty in climate projections. Ultrafine aerosol particles smaller than 50 nanometers (UAP <50) can be abundant in the troposphere but are conventionally considered too small to affect cloud formation.Observational evidence and numerical simulations of deep convective clouds (DCCs) over the Amazon show that DCCs …
