The next-generation of hierarchical composites needs to have built-in functionality to continually monitor and diagnose their own health states. This paper includes a novel strategy for in-situ monitoring the processing stages of composites by co-braiding CNT-enabled fiber sensors into the reinforcing fiber fabrics. This would present a tremendous improvement over the present methods that exces...

OBJECTIVE The aim of this study was to determine the effects of light intensity and type of light unit (quartztungsten-halogen [QTH] or light-emitting diode [LED]) on the hardening of various resin cements and a resin composite restorative. METHODS Disk specimens were prepared from 4 dual-cured resin cements (Variolink II, Calibra, Nexus 2 and RelyX ARC). Two QTH light-curing units (Visilux 2...

Novel, effective methods to control and prevent spoilage and contamination by pathogenic microorganisms in meat and meat products are in constant demand. Non-thermal pasteurization is an ideal method for the preservation of meat and meat products because it does not use heat during the pasteurization process. Atmospheric pressure cold plasma (APCP) is a new technology for the non-thermal pasteu...

Prepregs of a mixture of the tetrafunctional epoxy tetraglycidyl 4.4-diaminodiphenyl methane (TGDDM) and the tetrafunctional amine 4.4'-diaminodiphenylsulfone (DDS) were characterized with temperature-modulated DSC (TMDSC) as well as dynamic mechanical analysis (DMA). The baseline shift of the glass transition was separated from the curing exotherm by using temperature-modulated and step scan D...

Myoglobin is a very important sarcoplasmic protein responsible for the colour of meat and meat products. This protein is degraded during post-mortem period (ageing) as well as during longer processes such as dry curing. In the present study, a total of eleven naturally generated fragments of myoglobin detected at the end of the processing of dry-cured ham have been identified for the first time...

The survival rate of Phytophthora ramorum was assessed when introduced at high rates into composts of varying provenance and curing time, produced by both “turned windrow” and “forced air static pile” techniques. Survival in some compost media was high and statistically indistinguishable from positive controls (P<0.01), while other sources were statistically indistinguishable from negative cont...

The strength of Ultra-High Performance Concrete (UHPC) can be sensitively affected by the curing method used. However, in contrast to the precast plant production of UHPC where a standard high-temperature steam curing is available, an optimum curing condition is rarely realized with cast-in-place UHPC. Therefore, the trend of the compressive strength development of UHPC was experimentally inves...

The aim of this study was to establish a relationship between the mechanical properties of a powder coating, extracted using ultrasonic analyses, and the extent of its curing. This study was necessitated by the fact that most current methods either focus on in-process temperature monitoring or on laboratory analysis of powder samples and not on post-curing characterization of industrial samples...

This paper investigates application of piezoelectric ceramics mounted on surface of mould to monitor flow front and curing phases of resin in Resin Transfer Moulding (RTM) process. The piezoelectric ceramic is used for both generating ultrasound and measuring energy of echoed ultrasonic wave at the interface of mould and resin. One of the advantages of this method is that the piezoelectric cera...

In this study, a peptidomic approach has been used in the identification of naturally generated peptides during a dry-curing process, showing methionine (Met) oxidation in their sequence. A total of 656 peptides derived from major myofibrillar proteins in Protected Designation of Origin (PDO) Teruel dry-cured ham have been identified by nanoliquid chromatography coupled to tandem mass spectrome...
