Strategies for Safely Handling Industrial Azide Reactions: The Three Traps
Industrial use of azides requires special care to avoid explosions or poisonings. Life-cycle management of azide is discussed from the time azide-containing material is received at the front gate, sampled and stored, moved to the plant, placed in reactors, and finally until all wastes are abated and all equipment deco…
SnSe Thin Film Electrodes Prepared by Vacuum Evaporation: Enhancement of Photoelectrochemical Efficiency by Argon Gas Condensation Method
The effect of argon gas condensation (AGC) on crystallinity, surface morphology and photoelectrochemical (PEC) characteristics of SnSe thin films, prepared by thermal vacuum deposition onto ITO/glass substrates, has been investigated. The focal theme was to improve growth process of SnSe thin films and consequently en…
Finite element optimization by pulsed thermography with adaptive response surfaces
A finite element (FE) model is updated and optimized by making use of the surface temperature distribution captured with pulsed thermography (PT) on a PVC plate. The temperature distribution across the surface can be measured. As the amount of experimental data to be used in this case is very high, an accurate, time-e…
Exposition orale aux nanoparticules de dioxyde de titane (TiO2) : du franchissement de l’épithélium buccal et intestinal au devenir et aux effets dans l’organisme
As we are faced with the exponential use of nanomaterials in consumer products, including food, the consequences of daily exposure to nanoparticles at low doses set public health issues for humans. Among the different routes of exposure, the oral route remains the less documented, although nanomaterials are commonly u…
Development of a three dimension multi-physics code for molten salt fast reactor
Molten Salt Reactor (MSR) was selected as one of the six innovative nuclear reactors by the Generation IV International Forum (GIF). The circulating-fuel in the can-type molten salt fast reactor makes the neutronics and thermo-hydraulics of the reactor strongly coupled and different from that of traditional solid-fuel…
Novel completed biodegradable polymer sirolimus-eluting stent versus durable polymer sirolimus-eluting stent in de novo lesions: nine-month angiographic and three-year clinical outcomes of HOPE trial.
BACKGROUND: Drug-eluting stents (DES) with durable polymer have significantly reduced restenosis and target vessel revascularization compared with bare metal stents. Durable polymer has been linked with persistent inflammation of vessel wall and delayed endothelial healing that may increase the risk of late and very l…
Photodynamic therapy for cancer treatment and the new antitumor photosensitizer sinoporphyrin sodium
Photodynamic therapy(PDT) is a promising new cancer treatment.This therapy involves the combination of a photosensitizer and visible light.When the photosensitizer is injected into the patient,it will be soon enriched in tumor tissue while the tumor tissue is irradiated with light of a specific wavelength.It can produ…
Experimental study on collapse resistance of welded beam-column connection substructure of steel frame based on seismic design
Three welded beam-column connection substructures of steel frame with two kinds of weld access holes( fan-shaped and enlarged weld access hole) were designed based on the Chinese seismic code and relevant references. The impact tests using drop-hammer were carried out to simulate the dynamic behavior of structural pro…
Bursting liability of coal research of heterogeneous coal based on particle flow microscopic test
To research the influence of different heterogeneous parameters on bursting liability of coal,the uniaxial compressing tests of heterogeneous coal based on Weibull distribution with different elastic modulus and bonding strength were simulated by using particle flow code( PFC). The accumulation and release of energy w…
Application of the synthetic wax to improve the foamed bitumen parameters used in half-warm bituminous mixtures
The need for bitumen modification allowing lower asphalt production temperatures is a direct result of economic and environmental issues. Compared with the traditional Hot Mix Asphalt (HMA) technology, foamed bitumen used in the Warm and Half Warm Mix Asphalt (WMA, HWMA) processes provides an approximately 30–40 °C re…
An Experimental Study of Flexural Strength of Reinforced Concrete Beam Due To Corrosion
Reinforced concrete beams are normally designed as under reinforced to provide ductile behavior such as the tensile moment of resistance.In coastal environment reinforcement corrosion is an obvious cause of deterioration of concrete structure, which affects the durability and service of reinforced concrete structure.S…
Tribo-corrosion Behavior of Electroless Ni-P Coatings in Alkaline Corrosive Environment
The present article considers an experimental study of tribo-corrosion behavior of electroless Ni-P coatings in alkaline environment sliding against alumina. The study of wear and friction behaviour is carried out using different load and sliding speed with the help of a pin-on-disk tribometer. The wear rate increases…
The Effects of Fine Particle Peening on Surface Residual Stress of a TRIP-Aided Bainitic Ferrite Steel
To apply a transformation-induced plasticity (TRIP)-aided steel consisting of bainitic ferrite structure matrix and metastable retained austenite of 10 vol% (TBF steel) to some precision gears, the effects of fine particle peening on the Vickers hardness and residual stress in a surface layer of the TBF steel were inv…

Catalytic Pyrolysis of General Purpose PolyStyrene Using Red Mud as a Catalyst
In this work, the influence of Red Mud in the pyrolysis of general purpose polystyrene (GPPS) has been studied. The catalytic pyrolysis experiments were carried out using an unstirred semi-batch stainless steel 6.28 liter reactor under nitrogen atmosphere (air free) with Red Mud as a catalyst. The reaction effluents (…
Suppression of Silver Dissolution by Contacting Different Metals during Copper Electrorefining
Electrolytic copper contains, on average, 10 ppm silver as impurity, which leads to a loss of silver as a cashcow product for copper smelters.Most of silver included in blister copper anodes passes into anode slime when electrolyzed, keeping the elemental state. However, once a part of elemental silver dissolves from…
Density-Functional Theory Investigation of Sr 2 CrOsO 6 with Cubic Symmetry Using Modified Becke—Johnson Potential
We investigate the electronic structures and optical dielectric functions of the high temperature phase of Sr 2 CrOsO 6 with cubic structure by using Tran and Blaha's modified Becke and Johnson exchange potential. In the absence of spin-orbit coupling, the total spin moment is 0μ B . When spin-orbit coupling is includ…
Quantum phase transitions and topological proximity effects in graphene nanoribbon heterostructures
Topological insulators are bulk insulators that possess robust chiral conducting states along their interfaces with normal insulators. A tremendous research effort has recently been devoted to topological insulator-based heterostructures, in which conventional proximity effects give rise to a series of exotic physical…
Effect of Hot Rolling on Al-4.5%Cu Alloy Reinforced Fly Ash Metal Matrix Composite
Today’s world has an increasing interest in composites containing low density and low cost reinforcements. However, these materials endure from poor distribution of the reinforcement in matrix and increase in porosity level. Fly ash is one of the low density reinforcement available in abundant and going as waste from…
