Abstract 3D polymer-based printers have become easily accessible to the public. Usually, the technology used by these 3D printers is Fused Deposition Modelling (FDM). The majority of these 3D printers mainly use acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) to fabricate 3D objects. In order for the p…
In this paper, temperature dependence of nanoporous framework evolution process and variety of pore properties (pore volume, specific surface area (BET), and pore size) of SiO 2 aerogels were characterized by FTIR, XPS, XRD, SEM, TEM, BET, BJH, etc. Results show that SiO 2 aerogels treated at different temperatures al…
Adult stem cells are excellent cell resource for cell therapy and regenerative medicine. Dental pulp stem cells (DPSCs) have been discovered and well known in various application. Here, we reviewed the history of dental pulp stem cell study and the detail experimental method including isolation, culture, cryopreservat…
BACKGROUND: Dilute oxalic acid pretreatment has drawn much attention because it could selectively hydrolyse the hemicellulose fraction during lignocellulose pretreatment. However, there are few studies focusing on the recovery of oxalic acid. Here, we reported a new approach to recycle oxalic acid used in pretreatment…
Karst bauxite deposits are currently investigated as a new resource for rare earth elements (REE) in order to avoid present and future supply shortfalls of these critical metals. The present work focuses on the geochemistry and mineralogy of the REE in karst bauxite deposits of the Catalan Coastal Range (CCR), NE-Spai…
Introduction: The development of targeted drug delivery systems is a rapidly growing area in the field of nanomedicine. Methods: We report herein on optimizing the targeting efficiency of a lipid nanoparticle (LNP) by manipulating the acid dissociation constant ( pKa ) value of its membrane, which reflects its ionizat…
Information-centric networking (ICN), a new networking paradigm in which the focal point is a named data, has been proposed recently as an evolving concept to the actual host-centric model of the Internet that relies mainly on host addresses. In vehicular networks, where vehicles are generally moving network elements…
We report evidence of Re and Mo segregation (up to 2.6 at.% and 1 at.%) along with Cr and Co to the dislocations inside of {\gamma}' precipitates in a second generation Ni-based single crystal superalloy, after creep deformation at 750{\deg}C under an applied stress of 800 MPa. The observed segregation effects can be…
Resistive random access memory (RRAM) is attractive for neuromorphic computing systems as synaptic weights. In the neural network training, incremental switching occurs between the analog conductance states, thus the analog RRAM devices have unique endurance degradation behaviors compared to the convention digital mem…
The iron and steel industry is still dependent on fossil coking coal. About 70% of the total steel production relies directly on fossil coal and coke inputs. Therefore, steel production contributes by ~7% of the global CO2 emission. The reduction of CO2 emission has been given highest priority by the iron- and steel-m…
We report the experimental observation of hysteresis-free negative capacitance (NC) in thin ferroelectric Hf0.5Zr0.5O2(HZO) films through high-speed pulsed charge-voltage measurements. Hysteretic switching is suppressed by the addition of thin Al2O3layers on top of the HZO to prevent the screening of the polarization.…
This paper studied the fire resistance of rice husk ash concrete. An experimental method was adopted as the research design in this work, which produced one hundred and eighty four (184) concrete specimens with the addition of rice husk ash in weighted percentages of 5%, 10% and 15% respectively. They were cured and t…
A novel chlorine and alkylsilyl substituted polymer PBZ-ClSi was synthesized and the nonhalogen solvent-processed PSCs achieved an efficiency of 12.8%.
A new surge of interest in paper electronics has arisen due to the numerous merits of simple micro-/nanostructured substrates. In article number 1801588, Jinghua Yu, Hong Liu, and co-workers present a comprehensive review on flexible paper electronics with features of being thin, lightweight, cost-effective, biodegrad…
One-dimensional metrics can be considered an upper bound on the performance that can be achieved given an implosion with an imploding mass Mimp and a given adiabat α, driven to an implosion velocity V by a specified ablation pressure Pa for single shell capsules with low-opacity ablators. The quantitative value of an…
In-memory computing is an emerging non-von Neumann approach in which certain computational tasks such as matrix-vector multiplication are performed using resistive memory devices organized in a crossbar array. However, the conductance variations associated with the memory devices limit the precision of this computatio…
BACKGROUND: Current multi-petaflop supercomputers are powerful systems, but present challenges when faced with problems requiring large machine learning workflows. Complex algorithms running at system scale, often with different patterns that require disparate software packages and complex data flows cause difficultie…
The purpose of this study was to prepare and evaluate the chitosan-tripolyphosphate (CS-TPP) nanoparticles suspension as an antibacterial agent. Material and Methods: CS-TPP nanoparticles suspension was prepared by the ionic gelation method with various concentrations of CS and TPP. The prepared nanoparticles suspensi…
BACKGROUND: Silver sulfadiazine (AgSD) is widely employed as an antibacterial agent for surface burn management. However, the antibacterial activity of AgSD was restrained because of the lower drug solubility and possible cytotoxicity. OBJECTIVE: This study aimed to formulate stable silver sulfadiazine/nanosuspensions…
In all amniotes specialized intermediate filament keratins (IF-keratins), in addition to keratin-associated and corneous proteins form the outermost cornified layer of the epidermis. Only in reptiles and birds (sauropsids) the epidermis of scales, claws, beaks, and feathers, largely comprises small proteins formerly i…
