Exploring the Self-Assembly Capabilities of ABA-Type SBS, SIS, and Their Analogous Hydrogenated Copolymers onto Different Nanostructures Using Atomic Force Microscopy
(MDPI, 2018-09)
In this work, the self-assembled morphologies obtained for poly(styrene-b-butadiene-b-styrene) (SBS) and poly(styrene-b-isoprene-b-styrene) (SIS) ABA-type copolymers were investigated before and after hydrogenation of the ...
Numerical Model for Predicting Bead Geometry and Microstructure in Laser Beam Welding of Inconel 718 Sheets
(MDPI, 2018-07)
A numerical model was developed for predicting the bead geometry and microstructure in laser beam welding of 2 mm thickness Inconel 718 sheets. The experiments were carried out with a 1 kW maximum power fiber laser coupled ...
Combination of Laser Material Deposition and Laser Surface Processes for the Holistic Manufacture of Inconel 718 Components
(MDPI, 2018-07)
The present work proposes a novel manufacturing technique based on the combination of Laser Metal Deposition, Laser Beam Machining, and laser polishing processes for the complete manufacturing of complex parts. Therefore, ...
Formation of Palygorskite Clay from Treated Diatomite and its Application for the Removal of Heavy Metals from Aqueous Solution
(MDPI, 2018-09-15)
Environmental contamination by toxic heavy metals is a serious worldwide phenomenon. Thus, their removal is a crucial issue. In this study, we found an efficient adsorbent to remove Cu2+ and Ni2+ from aqueous solution using ...
Funcionamiento democrático y ABP: factores determinantes para la inclusión y el rendimiento del alumnado
(Universidad Autónoma de Baja California, 2018-06)
Este trabajo analiza cómo el funcionamiento democrático y la metodología basada en proyectos (ABP) influyen en el rendimiento del alumnado. Se relacionan las evidencias descritas en la literatura científica sobre la mejora ...
Association of Notch-1, osteopontin and stem-like cells in ENU-glioma malignant process
(Impact Journals LLC, 2018-07-31)
Notch-1 and osteopontin (OPN) mediate angiogenesis and glioma stem-like cell (GSLC) maintenance. However, the relationship between these molecules and GSLCs during the development of glioma is unknown. We investigate the ...
Case Study to Illustrate the Potential of Conformal Cooling Channels for Hot Stamping Dies Manufactured Using Hybrid Process of Laser Metal Deposition (LMD) and Milling
(MDPI, 2018-02)
Hot stamping dies include cooling channels to treat the formed sheet. The optimum cooling channels of dies and molds should adapt to the shape and surface of the dies, so that a homogeneous temperature distribution and ...
Effect Of Reaction Conditions On The Surface Modification Of Cellulose Nanofibrils With Aminopropyl Triethoxysilane
(MDPI, 2018-04-13)
Nine different surface modifications of cellulose nanofibrils (CNF) with 3-aminopropyl triethoxysilane (ATS) by using three different solvent systems (water, ethanol, and a mixture of both) were investigated. The effect ...
Analysis of the Influence of the Use of Cutting Fluid in Hybrid Processes of Machining and Laser Metal Deposition (LMD)
(MDPI, 2018-02)
Hybrid manufacturing processes that combine additive and machining operations are gaining relevance in modern industry thanks to the capability of building complex parts with minimal material and, many times, with process ...
Acute depletion of diacylglycerol from the cis -Golgi affects localized nuclear envelope morphology during mitosis
(American Society for Biochemistry and Molecular Biology, 2018-08)
Dysregulation of nuclear envelope (NE) assembly results in various cancers; for example, renal and some lung carcinomas ensue due to NE malformation. The NE is a dynamic membrane compartment and its completion during mitosis ...
