Se Nanopowder Conversion into Lubricious 2D Selenide Layers by Tribochemical Reactions
Advanced Materials, Volume 35, Issue 42, October 19, 2023., 2023 A simple sprinkling of Se nanopowders onto sliding Mo and W thin films leads to the tribochemical in operando formation of lubricious 2D selenides. Due to the thermal and vacuum stability of the Se nanopowders they can be used to replenish sliding components with solid lubricants, avoiding the long‐lasting problem of transition metal ...

Batteries &Supercaps, Volume 6, Issue 10, October 2023., 2023 Temperature matters. Despite the large number of publications available, a lack of consensus still exists on the effect of the carbonization temperature on the textural and structural features of biomass‐derived carbons. In this respect, an exhaustive physicochemical and electrochemical characterization is reported here, from which relevant insights on

Non-renormalization Theorems without Supersymmetry [PDF]
, 2015 We derive a new class of one-loop non-renormalization theorems that strongly constrain the running of higher dimension operators in a general four-dimensional quantum field theory.

Study on Thixojoining Process Using Partial Remelting Method
Advances in Materials Science and Engineering, 2013 Cold-work tool steel is considered to be a nonweldable metal due to its high percentage content of carbon and alloy elements. The application of a new process of the semisolid joining of two dissimilar metals is proposed. AISI D2 cold-work tool steel was
