In the present study, friction spot welding or refill friction stir spot welding was performed to consolidate dissimilar AA5754 Al and AZ31 Mg alloys. The intermetallic compounds of Al12Mg17 and Al3Mg2 were primarily found in the weld, distributed at the interface between the base materials and in the Al top sheet. The distribution of the intermetallic compounds and the interfacial area between...

Endoscopic tissue shielding with polyglycolic acid (PGA) sheets (Neoveil; Gunze Co., Kyoto, Japan) and fibrin glue (Beriplast P CombiSet; CSL Behring Pharma, Tokyo, Japan) is a promising method for preventing postoperative complications [1–3]. However, this technique is thought to be inefficient for covering large mucosal defects because it takes time to deliver many small PGA sheets. According...

Bentonite clay collected from Jabal Umm Ali area NE of Khartoum (Sudan) was characterized by X-ray diffraction (XRD). It was then purified by treatment with distilled water and activated with sulfuric acid at 90 oC for 3.5 hrs. XRD indicated modification of activated bentonite with enhanced surface area. Several cations were removed from octahedral sheet (Mg, Al, and Fe). Increasing the acid co...

Low molecular weight gelators that are not easily degraded by enzymes have a range of potential applications. Here, we report new Fmoc-protected dipeptides in which the amide carbonyl group has been replaced by an oxetane ring. Remarkably one of these peptidomimetics, but not the corresponding dipeptide, is an effective gelator, forming hydrogels at a concentration of 3 mg mL-1. On assembly, th...

This document presents 30 different privacy guidelines that can be used to both design and assess IoT applications and IoT middleware platforms. These guidelines can be broadly categorised into eight categories, namely, MINIMIZE ( ), HIDE ( ), SEPARATE ( ), AGGREGATE ( ), INFORM ( ), CONTROL ( ), ENFORCE ( ), DEMONSTRATE ( ). This document uses the following structure to introduce the each priv...

Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad frequency range. In addition, the measurements can be done quantitatively so that images of microwave materials properties can be created. We rev...

We report the direct and self-selective synthesis of Ag nanowires (NWs) on graphene patterns through a modified citrate reduction reaction approach. High-density NWs were selectively formed only on the graphene areas, whereas NWs were not synthesized on the SiO2/Si and glass substrates. The size and density of the Ag NWs gradually increased with increasing reaction time and AgNO3 concentration....

1.1.3.) Produce a statistical summary that includes: (a.) counters for the spectral combinations produced, binned by brightest-band magnitude; (b.) mean position offsets and variances on both position axes for all band-pair combinations; (c.) chi-square values for all band-pair position discrepancies, binned by brightest-band magnitude. Items (b.) and (c.) will use only bandmerged sources with ...
