An experimental study on wear properties of the drive elements with deep cryogenic treatment under the extreme contact pressure

Y.P. Chang、Li Ming Chu、C.T. Liu 等 4 位作者2020-08-04OpenAlex

The wear of the transmission components is the main cause of mechanical damage. There will be deformation and loss between the ball and the track after a long time under extreme pressure conditions. Moreover, the temperature rise after the friction action will have a great impact on the wear level. These will cause wo…

Greenhouse effect and air pollution caused by using agricultural waste as biomass power generation sources: A case study in Yunlin County

Chuan-Hsi Shih、Huann-Ming Chou2020-08-04OpenAlex

A 2019 report by the International Energy Agency indicated that greenhouse gas emissions resulting from global energy use increased to 33.1 Gt in 2018, reaching a record high. The growth of global energy consumption in 2018 was twice the average growth during 2010 and 2018. The human race across the planet is living i…

Structure-activity relationships of amino acids in Marthasterias glacialis chemoreception

Tine Valentinĉic2020-08-04OpenAlex

Structure-activity relationship studies of amino acids in chemoreception of Marthasterias glacialis revealed that the substances inducing feeding are of low molecular weight and have two to six carbon atoms in molecule. Evidence is presented that the sulfhydryl group plays a rôle in response to L-cysteine. In L-cystei…

Spectroscopic Investigations of Excited Charge Carriers in II-VI Nanoparticles

William M. Sanderson2020-08-04Open Scholarship Institutional Repository (Washington University in St. Louis)

The large absorption cross sections and the tunability of the energetic spacings between the states in the conduction (CB) and valence band (VB) within a semiconductor nanoparticle (NP) make them promising media for capturing electromagnetic radiation and converting it into charge carriers, or electricity. In photovol…

Defect formation in a graphene overlayer on ruthenium under high pressure

Michele Pisarra、Cristina Dı́az、Fernando Martı́n2020-08-04Physical review. B./Physical review. B

Due to its highly corrugated moir\'e structure and the nanometer modulation of its electronic properties, graphene deposited on ruthenium substrates (G-Ru for short) is a versatile playground for molecular deposition and chemical reactivity. Under local ultrahigh pressure conditions, one can expect an even richer beha…

Catalytic Asymmetric Reduction of Nitroalkenes

Irishi N. N. Namboothiri、Meeta Bhati、Madhu Ganesh 等 7 位作者2020-08-04OpenAlex

Catalytic asymmetric reductions of β-disubstituted nitroalkenes, including bioreduction, are summarized in this chapter. Various metal-ligand catalysts and organocatalysts such as Hantzsch ester and reductase enzymes have been employed to generate β-disubstituted nitroalkanes with a β-chiral center with good-to-excell…

Frozen waterfall and a video of supercooled water turning into frazil ice

Michael J. Ruiz、Charles Cranford2020-08-04Physics Education

Abstract In early January 2018, after days of subfreezing temperatures, a 20 m waterfall became mostly frozen with supercooled water pouring over the top of the frozen parts of the fall. A video was taken of the waterfalls and supercooled turbulent water flowing on the frozen surface as it turned into frazil ice right…

Nanoscale indentation of plasma membrane establishes a contractile actomyosin scaffold through selective activation of the Amphiphysin-Rho1-Dia/DAAM and Rok pathway

Tushna Kapoor、Pankaj Dubey、Seema Shirolikar 等 4 位作者2020-08-04bioRxiv (Cold Spring Harbor Laboratory)

Abstract Nanoscale bending of plasma membrane increases cell adhesion, induces cell-signalling, triggers F-actin assembly and endocytosis in tissue-cultured cells. The underlying mechanisms are not very well understood. Here, we show that stretching the plasma membrane of somatic cyst cell around rigid spermatid heads…

Effect of Amine Structure on the Corrosivity of a Carbon Steel Natural Gas Processing Plant

Jessica Narku-Tetteh、Pailin Muchan、Teeradet Supap 等 4 位作者2020-08-04SPE Nigeria Annual International Conference and Exhibition

Abstract This work investigated and correlated the corrosiveness of different amines with their uniquely inherent structural characteristics, specifically focusing on the effect of alkyl chain lengths of alkanolamines and diamines, and the effect of the number of -OH groups in sterically-hindered amines. The amines st…

Mesenchymal stem cell mediated delivery of Extracellular Vesicle (EV)-encapsulated microRNAs for the treatment of breast cancer

Katie Gilligan2020-08-04Arrow@dit (Dublin Institute of Technology)

Mesenchymal Stem Cells (MSCs) hold the ability to home to the site of the tumour and bypass the host immune system. Extracellular Vesicles (EVs) are thought to be a fingerprint of the parent cell and therefore MSC-EVs may retain these cancer targeting properties and immune privilege. The development of a novel MSC-EV…

Quantum multifractality in thermal conduction across random interfaces

Taishan Zhu、Giuseppe Romano、Lina Yang 等 5 位作者2020-08-04arXiv (Cornell University)

Self-affine morphology of random interfaces governs their functionalities across tribological, geological, (opto-)electrical and biological applications. However, the knowledge of how energy carriers or generally classical/quantum waves interact with structural irregularity is still incomplete. In this work, we study…
