Exploring and understanding the protein-folding problem has been a long-standing challenge in molecular biology. Here, using molecular dynamics simulation, we reveal how parallel distributed adjacent planar peptide groups of unfolded proteins fold reproducibly following explicit physical folding codes in aqueous environments due to electrostatic attractions. Superfast folding of protein is found to be powered by the contribution of the formation of hydrogen bonds. Temperature-induced torsional waves propagating along unfolded proteins break the parallel distributed state of specific amino acids, inferred as the beginning of folding. Electric charge and rotational resistance differences among neighboring side-chains are used to decipher the physical folding codes by means of which precise secondary structures develop. We present a powerful method of decoding amino acid sequences to predict native structures of proteins. The method is verified by comparing the results available from experiments in the literature Copyright © 2019, The Authors. All rights reserved.

A non-conjugated polymer acceptor PF1-TS4 was firstly synthesized by embedding a thioalkyl segment in the mainchain, which shows excellent photophysical properties on par with a fully conjugated polymer, with a low optical band gap of 1.58 eV and a high absorption coefficient >105 cm−1, a high LUMO level of −3.89 eV, and suitable crystallinity. Matched with the polymer donor PM6, the PF1-TS4-based all-PSC achieved a power conversion efficiency (PCE) of 8.63 %, which is ≈45 % higher than that of a device based on the small molecule acceptor counterpart IDIC16. Moreover, the PF1-TS4-based all-PSC has good thermal stability with ≈70 % of its initial PCE retained after being stored at 85 °C for 180 h, while the IDIC16-based device only retained ≈50 % of its initial PCE when stored at 85 °C for only 18 h. Our work provides a new strategy to develop efficient polymer acceptor materials by linkage of conjugated units with non-conjugated thioalkyl segments. © 2020 The Authors.

Error Compensation for 3D Digital Laser Scanning Data Based on the Surface of Aluminum Coated F-12 Aramid Plain Weave Fabric and a Test of Configuration for Large Balloon

The measurement of the configuration parameters for the large balloon is an important content, including volume, surface area and specific size under a certain internal pressure. Non-contact measurement techniques using laser scanning have the advantage of fast acquiring large numbers of points. However, compared to their contact-based counterparts, these techniques are known to be less accurate. Furthermore, this accuracy depends on different parameters such as materials properties, surface texture, product color, etc. The large balloon is made by aluminum coated F-12 aramid plain weave fabric pieces. The digitizing errors for high-speed 3D digital laser scanning data based on the surface of F12 fabric material are analyzed and characterized in this paper. With error characterisation, an empirical model is obtained relating the errors to the influencing factor. Establishing a reasonable test scheme and using the technology of laser scanning, the spatial information of the surface for large balloon can be obtained quickly. The empirical formula is used to compensate for 3D laser scanning data of large balloon. The problem of compensation for 3D laser scanning data for improved test accuracy is addressed. The more accurate parameters of the configuration for large balloon are quickly obtained. This provides a method for the rapid, high-efficiency and high-precision test of configuration for large balloon.

Metastable metallic phases of two‐dimensional (2D) transition metal dichalcogenide (TMD) nanomaterials have attracted great research interest and promoted the applications of sustainable energy storage and conversion sources. These TMD‐based nanomaterials exhibit an excellent electrochemical performance because of their abundant active sites and extraordinary physicochemical properties. This review provides deep insights into recent progress and highlights key challenges for defect engineering in the metastable phases of TMDs.

A new method of coupling finite element method (FEM) and peridynamics (PD) is proposed to analyze the progressive damage of fiber reinforced composite laminate. The computational efficiency of FEM is higher than peridynamics. But peridynamics is good at calculating discontinuous solution. In order to exert the advantages of the above two methods, the solution is divided into three parts. In the dangerous region, peridynamics is adopted. And FEM is used in the non-dangerous region. The remaining region is the coupling FEM/PD region, where the peridynamics particles are interacted with neighboring finite element nodes each other. And the contribution stiffness of FEM and peridynamics particles can be written in the global stiffness matrix together. The substructure method is also used to reduce computational effort further. The progressive damage and failure modes of composite laminates under a tensile load can be successfully analyzed. It is shown that this proposed method had a great potential to analyze the mechanical behavior of composites. © 2017 International Committee on Composite Materials. All rights reserved.
