| 1 | Superabsorbent Fibers for Comfortable Disposable Medical Protective Clothing显示文摘Disposable medical protective clothing for 2019-nCoV mainly consists of stacked layers with nanopore films,polymer coated nonwoven fabrics and melt-blown nonwoven fabrics against anti-microbial and anti-liquid penetration.However,such structures lack moisture permeability and breathability leading to an uncomfortable,stuffy wearing experience.Here,we propose a novel medical protective clothing material with a superabsorbent layer to enhance moisture absorption.Poly(acrylic acid-co-acrylamide)/polyvinyl alcohol superabsorbent fibers(PAAAM/PVA fibers)were prepared via wet spinning.And the superabsorbent composite layer was stacked from PAAAM/PVA fibers,bamboo pulp fibers(BPF)and ethylene-propyl-ene side by side fibers(ESF).The novel disposable medical protective composite fabric was obtained through gluing the superabsorbent layer to the inner surface of strong antistatic polypropylene nonwoven fabric.The resultant composite fabric possesses excellent absorption and retention capacity for sweat,up to 12.3 g/g and 63.8%,and a maximum hygroscopic rate of 1.04 g/h,higher than that of the conventional material(only 0.53 g/h).The moisture permeability of the novel material reached 12,638.5 g/(m^(2) d),which was 307.6%of the conventional material.The novel material can effectively reduce the humidity inside the protective clothing and significantly improve the comfort of medical staff. | Lin Yang Hong Liu Shuai Ding Jiawei Wu Yan Zhang Zhongzhen Wang Lili Wei Mingwei Tian Guangming Tao | 2020 | Advanced Fiber Materials2020，2，3： | 11 |

| 3 | Integrated representation of geospatial data,model,and knowledge for digital twin railway显示文摘The real-time accurate description of all spatial features of railway and their spatiotemporal relationships is a crucial factor in realizing comprehensive management and related decision-making within the entire life cycle of railways.Nevertheless,available spatiotemporal data models mainly use static historical sequence data,which are insufficient to support multi-source heterogeneous real-time sensed data;they lack a systematic depiction of the interactive relationships among multiple feature entities,and are limited to low-level descriptive analysis.Therefore,this study proposes a data-model-knowledge integrated representation data model for a digital twin railway,which explicitly describes the spatiotemporal,and interaction relationships among railway features through a conceptual knowledge graph.This study first analyzes the characteristics of railway features from above ground to underground,and then constructs a conceptual model to clearly describe the complex relationships among railway features.Secondly,a logical model is developed to illustrate the basic data structure.Thirdly,an ontology model is constructed as a basic framework for further deepening the domain knowledge graph.Finally,considering the prevention of landslides as an example,it demonstrates the abundant spatiotemporal relationships among railway related features.The results of this study bring more clear understanding of the complex interactive relationships of railway entities. | Hankan Li Qing Zhu Liguo Zhang Yulin Ding Yongxin Guo Haoyu Wu Qiang Wang Runfang Zhou Mingwei Liu Yan Zhou | 2022 | International Journal of Digital Earth2022，15，1： | 1 |

| 5 | Efficient and Generic Preparation of Diverse Polyelectrolyte Nanogels by Electrostatic Assembly Directed Polymerization显示文摘Nanogels hold promise as soft and functional carriers and nanoreactors,but whether they will ever reach the stage of large-scale application depends crucially on efficient production methods,and on what interesting properties and functionalities they can have.In particular,nanogels consisting of highly charged polyelectrolyte have not yet been very much explored.Here,the authors present a novel and generic strategy for controlled and efficient synthesis of a large diversity of polyelectrolyte nanogels.The method is based on polymerizing an ionic monomer in the presence of an oppositely charged polyion-neutral diblock copolymer as template,while adding a cross-linker.The growing polymer chains assemble with the template,forming polyion complex micelles,which dissociate upon increasing salt concentration.Subsequent separation yields nanogels with well-controlled size and properties,and free template polymers that can be used again.Our design can be applied generally to a wide range of both cationic and anionic monomers,as well as various cross-linkers.Scaled-up production presents no problems as increasing monomer concentration(hundreds of mM)and reaction volume(up to 1 L)hardly compromise product quality.Moreover,the obtained nanogels with their well-controlled size,morphology,chemistry,and cross-linking degree perform well as soft nanocarriers and catalytic nanoreactors. | Peng Ding Jianan Huang Cheng Wei Wei Liu Wenjuan Zhou Jiahua Wang Mingwei Wang Xuhong Guo Martien A.Cohen Stuart Junyou Wang | 2020 | CCS Chemistry2020，2，6： | 0 |
