Properties, preparation, and application of tungsten disulfide: a review

Journal of Physics D Applied Physics (2021)

Jinzi Ding Ailing Feng Xiaodong Li Shijiu Ding Liang Liu

Abstract Transition metal dichalcogenides (TMDs) attract research interest owing to their unique physical and chemical properties. Among the family of TMDs, tungsten disulfide (WS 2 ) has a unique band structure due to its semiconductor characteristics; namely, its broadband spectral response characteristics, ultra-fast bleach recovery time and excellent saturable light absorption. This article is a review of the current application of WS 2 in catalysts, lasers, batteries, photodetectors and lubricants. The review begins with a brief overview of the structure, properties and growth of WS 2 and describes the existing preparation methods for this material. Finally, methods for improving the performance of WS 2 in its current applications are presented. This review is limited to the most recent reports on this topic.

Synthesis of flower-like WS₂ by chemical vapor deposition*

Chinese Physics B (2021)

Jinzi Ding Wei Ren Ailing Feng Yao Wang Hao-Sen Qiao

Flower-like tungsten disulfide (WS 2 ) with a diameter of 5–10 μm is prepared by chemical vapor deposition (CVD). Scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), Raman spectroscopy, and ultraviolet-visible (UV-vis) spectroscopy are used to characterize its morphological and optical properties, and its growth mechanism is discussed. The key factors for the formation of flower-like WS 2 are determined. Firstly, the cooling process causes the generation of nucleation dislocations, and then the “leaf” growth of flower-like WS 2 is achieved by increasing the temperature.

Progress of Stimuli-Responsive Nanoscale Metal Organic Frameworks as Controlled Drug Delivery Systems

Current Drug Delivery (2020)

Ailing Feng Yanni Wang Jinzi Ding Rong Xu Xiaodong Li

Development of controlled drug delivery systems can improve the pharmacokinetic characteristics of drug molecules in the human body, thereby significantly improving the utilization rate of drugs and reducing toxicity and side effects caused by their high concentrations, which can occur when delivery is not controlled. Metal organic frameworks are a new class of very promising crystalline microporous materials, especially when the size is reduced to the nanometer range. Metal-organic frameworks exhibit large specific surface areas, tunable compositions, and easy functionalization. In recent years, an increasing number of studies have reported the remarkable advances in multifunctional nanoscale metal-organic frameworks in drug delivery.To review the latest research involving advances in stimuli-responsive nanoscale metal organic frameworks as drug delivery systems in controlled-release drugs.We first introduce the two main strategies associated with nanoscale metal organic frameworks used in drug loading: direct assembly and post-encapsulation. We next focus on the latest discoveries of nanoscale metal-organic framework-based stimulus response systems for drug delivery, including pH, magnetics, light, ion, temperature, and other stimuli, as well as multiple stimulus- responsive drug delivery systems. Finally, we discuss the challenges and future developmental directions of nanoscale metal-organic framework-based controlled drug release.
