Faulin, Tanize do Espirito Santo; Kazuma, Soraya Megumi; Tripodi, Gustavo Luis; Cavalcante, Marcela Frota; Wakasuqui, Felipe; Oliveira, Cristiano Luis Pinto; Degenhardt, Maximilia Frazão de Souza; Michaloski, Jussara; Giordano, Ricardo José; Ketelhuth, Daniel Francisco Jacon; Abdalla, Dulcineia Saes Parra

The electronegative low-density lipoprotein, LDL (?), is an endogenously modified LDL subfraction with cytotoxic and proinflammatory actions on endothelial cells, monocytes, and macrophages contributing to the progression of atherosclerosis. In this study, epitopes of LDL (?) were mapped using a phage display library of peptides and monoclonal antibodies reactive to…

Structural correlations tailor conductive properties in polymerized ionic liquids

Doughty, Benjamin; Genix, Anne-Caroline; Popov, Ivan; Li, Bingrui; Zhao, Sheng; Saito, Tomonori; Lutterman, Daniel A.; Sacci, Robert L.; Sumpter, Bobby G.; Wojnarowska, Zaneta; Bocharova, Vera

Polymerized ionic liquids (PolyILs) are promising materials for applications in electrochemical devices spanning from fuel cells to capacitors and batteries. In principle, PolyILs have a competitive advantage over traditional electrolytes in being single ion conductors and thus enabling a transference number close to unity. Despite this perceived advantage, surprisingly low…

Twisted Ribbon Aggregates in a Model Peptide System

Rüter, Axel; Kuczera, Stefan; Pochan, Darrin J.; Olsson, Ulf

The model peptides A8K and A10K self-assemble in water into ca. 100 nm long ribbon-like aggregates. These structures can be described as ?-sheets laminated into a ribbon structure with a constant elliptical cross-section of 4 by 8 nm, where the longer axis corresponds to a finite number, N ? 15,…

Structure Evolution of Polyethylene in Sequential Biaxial Stretching along the First Tensile Direction

Chen, Qiang; Chen, Dandan; Kang, Jian; Cao, Ya; Chen, Jinyao

Two linear low-density polyethylene samples (PE-A and PE-B), with similar melt index and molecular weight but different molecular structures, were used to explore the structural evolution during sequential biaxial stretching. Only PE-A could be successfully stretched into a film with the biaxial draw ratio of 6 × 6. The interlamellae…

Effect of side methyl from mixed diamine chain extenders on microphase separation and morphology of polyurethane fiber

You, Gexin; Wang, Jiaqi; Wang, Chunyan; Zhou, Xulin; Zhou, Xiuwen; Liu, Lina

Polyurethane fiber (PUF) can be used as self-adaptive material in the field of nuclear physics and its properties depended on the molecular structure. To explore the effect of side methyl on its degree of microphase separation (DPS) and morphology for PUF, ethanediamine and 1,2-propylene diamine with different molar ratio were…

Clustering-Triggered Emission and Persistent Room Temperature Phosphorescence of Sodium Alginate

Dou, Xueyu; Zhou, Qing; Chen, Xiaohong; Tan, Yeqiang; He, Xin; Lu, Ping; Sui, Kunyan; Tang, Ben Zhong; Zhang, Yongming; Yuan, Wang Zhang

Nonconventional biomacromolecular luminogens have attracted extensive interest due to their fundamental importance and potential applications in diverse areas. To explore novel luminogens and, moreover, to gain deeper insights into their emission mechanism, we study the emission behaviors of sodium alginate (SA), a natural anionic polysaccharide composed of mannuronic (M) and…

An inverted planar solar cell with 13% efficiency and a sensitive visible light detector based on orientation regulated 2D perovskites

Lian, Xiaomei; Chen, Jiehuan; Fu, Ruilin; Lau, Tsz-Ki; Zhang, Yingzhu; Wu, Gang; Lu, Xinhui; Fang, Yanjun; Yang, Deren; Chen, Hongzheng

Improving the film quality is of great importance in promoting the power conversion efficiency (PCE) of 2D perovskite-based solar cells (PVSCs), but the solution to this issue is limited. In this work, a strategy of combining the advantages of the ammonium thiocyanate (NH4SCN) additive and merged annealing (MA) process was…
