Defects in two-dimensional (2D) transition metal dichalcogenides (TMDs) have properties that are useful for optoelectronics, (1) sensing, (2) and electro/photocatalysis. (3,4) These properties are related to defect-induced in-gap states that modify the electronic structure of the host crystal. The in-gap states can trap excitons and give rise to defect-mediated photoluminescence (PL) (5,6) and even single-photon emission.

AbstractGraphene-based spintronic devices require efficient spin injection, and dielectric tunnel barriers are typically used to facilitate spin injection. However, the direct growth of ultrathin dielectrics on two-dimensional surfaces is challenging and unreliable. Here we report spin injection in graphene lateral spin valves using ferromagnetic van der Waals contacts of indium and cobalt (In–Co), and without the deposition of dielectric tunnel barriers.

3. Results 3.1. Formulation Development for “Jifang E” Sustained-Release InjectionPoloxamer 407 was chosen as a sustained-release excipient because it is a substance with amphiphilic properties of polyethylene oxide (PEO) and polypropylene oxide (PPO), which can be gelled below physiological temperature at concentrations of 15% to 30% (w/v), and the gelling temperature gradually decreases as the concentration increases (Figure 1A).
