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 …
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
A Co/CoO@NC hybrid material with high specific surface area and ultrafine particle size was prepared using a novel Co-MOF as a sacial 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.

Il y a beaucoup trop d'incohérence concernant le RP Civil, beaucoup trop de Civil se prennent pour Pablo bar. Cela est problématique pour l'évolution des personnages et encore plus pour avoir des approchants dans les fac illégale.
La rectification cylindrique est un usinage par abrasion qui permet de créer des surfaces parfaitement cylindriques. Comme en tournage, la pièce est mise en rotation sur son axe par une fixation entre pointes ou par mandrin. …
Ultrafine Pt nanoparticles with enhanced electron density promote the proton capture from electrolyte to catalyst surface, the dissociation of Pt−H bonds and successive release of H 2 molecules from the Pt surface. Abstract. Platinum (Pt) is the most effective bench-marked catalyst for producing renewable and clean hydrogen energy by ...
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 ...

Stereo image rectification • Image Reprojection – reproject image planes onto common plane parallel to line between optical centers – a homography (3x3 transform) applied to both input images – pixel motion is horizontal after this transformation – C. Loop and Z. Zhang. Computing Rectifying Homographies for Stereo Vision. IEEE Conf.
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.
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 …
