A Micro‐Nano Flower‐Like Na3V2(PO4)3@C Constructed by Polar‐Driven H‐Bond Engineering Toward High‐Rate Sodium Storage

open access: yesRare Metals, EarlyView.
ABSTRACT The polyanionic compound Na3V2(PO4)3 (NVP) has emerged as a competitive cathode material for sodium‐ion batteries (SIBs), owing to its high‐voltage redox activity (3.4 V vs. the Na+/Na reference couple) and NASICON‐type framework that enables superior ionic conductivity.

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.

The effect of flowering on adventitious root-formation

open access: yes
The rooting of cuttings from day-neutral tomato was not influenced by flower development, nor by SD or LD treatments of them or of the mother plants. In cuttings of the SD plant Perilla crispa flower initiation and development severely inhibited rooting. Leaves produced about 61 % of the roots, buds about 16 %, stems a small proportion.

The Impact of Dual‐Salt Electrolyte with Low Fluorine Content on the Performance of Layered Transition Metal Oxides for Sodium‐Ion Batteries

open access: yesSmall, EarlyView.
Dual‐salt electrolytes with low fluorine content high voltage sodium‐ion batteries cathodes: In this work, novel electrolytes containing two low fluorine content salts with enhanced safety features and the ability to passivate the Al current collector is reported. The suitability of these electrolytes in combination with P2‐Na2/3Al1/9Fe1/9Mn2/3Ni1/9O2 (
