Layered double hydroxides, a rare family of anion-exchangeable functional materials with broad application prospects, have received much attention both in academic research reports and technological patents. It was recently discovered that they could be exfoliated into unilamellar nanosheets in different solvents. Esp…
Abstract Rumseyite, ideally [Pb2OF]Cl, is a new mineral species which is associated with calcite, cerussite, diaboleite, hydrocerussite and undifferentiated Mn oxides in a small cavity in 'hydrocerussite' from a manganese pod at Merehead quarry, Somerset, England. Rumseyite is tetragonal, I4/mmm, a = 4.065(1), c = 12.…
Abstract Phase‐change random access memory (PCRAM) holds great promise as a future non‐volatile memory technology. All PCRAM devices have an inextricable relationship with thermodynamics. To make a memory cell crystallize or amorphize by injecting and removing thermal energy as a repetitive memory cycle results in the…

A PMSM stator inter turn short fault generates a back emf and an impedance unbalance. Those unbalance causes a torque ripple and an escalating partial heat defect. This paper proposes a fault detection scheme based on the PMSM dynamic model under the inter turn short which is derived in the positive and the negative s…
The present article presents a review devoted to Layered Double Hydroxide (LDH) as filler in coatings from the patent domain and the applicative literature. Other than bulk properties generally encountered in polymer nanocomposite aspect, LDHs filler relevance for coatings concerns surface properties as well as requir…
Gravimetric and electrochemical measurements were performed to investigate the effectiveness of an aliphatic amine compound with trade name of Armohib 28. It was found that the percentage inhibition efficiency increased with the increase of the compound concentration. Polarization curves indicate that the inhibitor un…
In this paper we demonstrate the design and development of a low-cost, self-powered, wireless sensor solution based on the WISP platform and utilizing thin films produced from environmentally friendly, water-based, inkjet printed graphene oxide (GO) ink. The sensor demonstrates good response to ammonia gas (NH3), yiel…
Summary An endemic diatom,Cyclotella rhomboideo‐ellipticaSkuja, from theYunnanPlateau, has been disappearing gradually from some lakes of the plateau. This study investigated the diatom's distribution in 30 lakes and documents long‐term population changes in the paleolimnological record of a deep lake,LakeFuxian. Livi…
This article compares chemical dechlorination treatments (immersion in sodium hydroxide or alkaline sulphite) and electrochemical treatments of iron bars from the Gallo-Roman period excavated from a marine environment. Some important parameters, such as storage before treatment, temperature, solution composition, and…
Reflecting two ways of impacting a garment sizing system-by modifying the body sizing table, and by modifying the ease amounts added (at bust and hip only), 4 garment sizing systems presenting the combinations of a standard (ASTM D5585-95R01) or a modified body sizing table, each with constant or size-dependent ease a…
We have investigated recently the role of voltage supply frequency on partial discharge inception voltage (PDIV) measurement for cavities embedded in a polyethylene matrix. From the experimental results, it was ascertained that lower frequencies could lead to lower PDIV values, whereas increasing the supply frequency…
Let G be a molecular graph, the Ediz eccentric connectivity index is defined as where is the sum of degrees of all vertices , adjacent to vertex , is the largest distance between and any other vertex of G or the eccentricity of . In this paper an exact formula for the Ediz eccentric connectivity index of one pentagona…
Abstract Na3SbSe3 was obtained by solid state reaction of anhydrous Na2Se, antimony, and selenium in a ratio of 3:2:3. It is air and moisture sensitive and melts at 870 K. Yellow single crystals of Na3SbSe3 were used for single‐crystal X‐ray diffraction. It crystallizes in the cubic space group P213 (No. 198) with a =…
This article reports a preliminary study on the effect of alloying on the antibacterial properties of silver and gold. Au-Ag alloy nanoparticles were synthesized in water by coreduction of the metal salts by sodium borohydride in the presence of sodium citrate as a capping agent. The particle morphology and size were…
“Technical textiles” is a buzz word now a day, it has wide range of applications, and in some cases it has completely replaced the conventional material. In recent years, researchers and industrial companies worldwide have been showing increasing interest in conductive textile products and textile-based composite mate…
Presented herein is a combined experimental and computational study of the gold nanoparticle (AuNP) inner filter effect on surface enhanced Raman spectroscopic (SERS) measurements. Using a bianalyte strategy in which dithiopurine (DTP) and ethanol were employed as the model analytes, we demonstrated that AuNPs enhance…
This study is devoted to the optical and electrical characterisation of discharges propagating over insulators made of polytetrafluoroethylene (PTFE) filled with different kinds of micro-mineral fillers immersed in gas or gaseous mixture, under lightning impulse voltage (1.2/50 µs), using a point-plane electrode arran…
In this work, we present an atomic scale study of the structural and chemical characteristics of interfaces between Ni and LaNbO 4 grains in Ni–LaNbO 4 cermets, a model composite material for anodes in proton-conducting solid-oxide fuel cells (SOFC). Electron energy loss spectroscopy (EELS) performed in an aberration-…
This paper presents a thermal analysis device, which can measure thermal conductivity of picoliter scale liquid sample. We employ the three omega method with a microfabricated AC thermal sensor with nanometer width heater. The liquid sample is confined by a micro-well structure fabricated on the sensor surface. The pe…
