Efficient and low-cost anode materials for the sodium-ion battery are highly desired to enable more economic energy storage. We describe here effects on an ultrathin carbon nitride film deposited on a copper metal electrode, the combination of which show an unusually high capacity to store sodium metal. The g-C 3 N 4 film is as thin as 10 nm and can be fabricated by an efficient, facile, and general chemical-vapor deposition method. A high reversible capacity of formally up to 51 Ah g -1 indicates that the Na is not only stored in the carbon nitride as such, but that carbon nitride activates also the metal for reversible Na-deposition, while forming at the same time an solid electrolyte interface layer avoiding direct contact of the metallic phase with the liquid electrolyte.

A graphitic carbon nitride nanostructure has been successfully functionalized by incorporation of different silver contents and subsequent modification with an α-rich protein, namely hemoglobin. Mech...
Due to the maximum atom-utilization efficiency and excellent catalytic properties, Au single atom catalysts (SACs) have been extensively studied in various catalytic systems. However, the performance ...
Modern knee implants combine several types of metal and therefore potentially expose patients to different metal ions. Titanium niobium nitride coating (TiNbN) acts like a physical barrie...
This is a multi-center, randomized study to compare blood and urine cobalt, chromium, and titanium ion levels of a metal-on-metal articular bearing coupled with two different head sizes to...
The brain has a high energy demand and requires continuous blood flow. The blood flow to the brain appears to be unaffected by small changes in blood pressure, but brain blood flow may be ...
The aim of this study is to demonstrate the non-inferiority of the ceramic-on-metal articulation using large diameter bearings (38mm to 60mm) compared to the metal on metal articulation us...
The evaluation of solitary pulmonary nodules (SPN) requires a balance between procedure-related morbidity and diagnostic yield, particularly in areas where tuberculosis is endemic. Data on...
Nanometer-sized tubes composed of various substances including carbon (CARBON NANOTUBES), boron nitride, or nickel vanadate.
Nanometer range spherical cores of particular semiconductor compounds surrounded by an ultrathin metal shell that is commonly made of gold or silver. This configuration gives the nanoshells highly tunable optical properties. They have potential in biomedicine for diagnosis and therapy.

Inorganic acids with a non metal, other than carbon, attached to hydrogen, or an acid radical containing no carbon.
Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
