Abstract
Covalent functionalization of tungsten disulfide (WS2 ) with photo- and electro-active nickel-porphyrin (NiP) is reported. Exfoliated WS2 interfacing NiP moieties with 1,2-dithiolane linkages is assayed in the oxygen evolution reaction under both dark and illuminated conditions. The hybrid material presented, WS2 -NiP, is fully characterized with complementary spectroscopic, microscopic, and thermal techniques. Standard yet advanced electrochemical techniques, such as linear sweep voltammetry, electrochemical impedance spectroscopy, and calculation of the electrochemically active surface area, are used to delineate the catalytic profile of WS2 -NiP. In-depth study of thin films with transient photocurrent and photovoltage response assays uncovers photo-enhanced electrocatalytic behavior. The observed photo-enhanced electrocatalytic activity of WS2 -NiP is attributed to the presence of Ni centers coordinated and stabilized by the N4 motifs of tetrapyrrole rings at the tethered porphyrin derivative chains, which work as photoreceptors. This pioneering work opens wide routes for water oxidation, further contributing to the development of non-noble metal electrocatalysts.

Abstract
ABSTRACT Introduction Table tennis is an explosive metabolic anaerobic sport of moderate intensity. Improving the level of its athletes depends on dedicated physical training methods. The Chinese state has invested more financial support for physical training believing in the effective possibility to improve the physical fitness and abilities of its table tennis athletes. Objective This study aims to analyze the effect of special physical training on table tennis players’ motor skills Methods This paper selects several table tennis players as research subjects. The volunteers were randomly divided into experimental and control groups. The experimental group adopted the exclusive physical training method. The control group underwent traditional training. Mathematical, statistical and experimental methods were used to analyze the impact of exclusive physical training on the motor skills of table tennis players. Results The test scores of the experimental group were significantly improved after four weeks and six weeks of exclusive physical training (P<0.01). There was no significant change in the three diagnostic test scores in the control group (P>0.05). After six weeks of a physical training intervention in the experimental group, the 0-score group disappeared. The distribution of the scores of the athletes gradually converges to the highest group. Conclusion Table tennis players showed good feedback on the functional intervention training protocol. Dedicated physical training positively affects the mastery, dexterity and skill in movement techniques of table tennis players. This work can provide a theoretical basis for scientific training of table tennis players. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Abstract
Covalent functionalization of two‐dimensional molybdenum disulfide (2D MoS2) holds great promise in developing robust organic‐MoS2 hybrid structures. Herein, for the first time, we demonstrate an approach to building up a bisfunctionalized MoS2 hybrid structure through successively reacting activated MoS2 with alkyl iodide and aryl diazonium salts. This approach can be utilized to modify both colloidal and substrate supported MoS2 nanosheets. We have discovered that compared to the adducts formed through the reactions of MoS2 with diazonium salts, those formed through the reactions of MoS2 with alkyl iodides display higher reactivity towards further reactions with electrophiles. We are convinced that our systematic study on the formation and reactivity of covalently functionalized MoS2 hybrids will provide some practical guidance on multi‐angle tailoring of the properties of 2D MoS2 for various potential applications.

Abstract
The covalent functionalization of MoS2 with a perylenediimide (PDI) is reported and the study is accompanied by detailed characterization of the newly prepared MoS2 -PDI hybrid material. Covalently functionalized MoS2 interfacing organic photoactive species has shown electron and/or energy accepting, energy reflecting or bi-directional electron accepting features. Herein, a rationally designed PDI, unsubstituted at the perylene core to act as electron acceptor, forces MoS2 to fully demonstrate for the first time its electron donor capabilities. The photophysical response of MoS2 -PDI is visualized in an energy-level diagram, while femtosecond transient absorption studies disclose the formation of MoS2 .+ -PDI.- charge separated state. The tunable electronic properties of MoS2 , as a result of covalently linking photoactive organic species with precise characteristics, unlock their potentiality and enable their application in light-harvesting and optoelectronic devices.

Abstract
The fascinating properties of single-layer graphene isolated by mechanical exfoliation have inspired extensive research efforts toward two-dimensional (2D) materials. Layered compounds serve as precursors for atomically thin 2D materials (briefly, 2D nanomaterials) owing to their strong intraplane chemical bonding but weak interplane van der Waals interactions. There are newly emerging 2D materials beyond graphene, and it is becoming increasingly important to develop cost-effective, scalable methods for producing 2D nanomaterials with controlled microstructures and properties. The variety of developed synthetic techniques can be categorized into two classes: bottom-up and top-down approaches. Of top-down approaches, the exfoliation of bulk 2D materials into single or few layers is the most common. This review highlights chemical and physical exfoliation methods that allow for the production of 2D nanomaterials in large quantities. In addition, remarkable examples of utilizing exfoliated 2D nanomaterials in energy and environmental applications are introduced.
