<p>Various fingerprint powder preparations used for fingerprints have a color or contrast and sticky material good adhesion. However, some chemical substrates powders are toxic the potential to harm health. This research is essential overcome this problem using new natural , namely dragon fruit peel powder, as latent development that was simple, non-toxic, cheaper than commercial powder. ...

This study reports piezoelectric properties and crystallographic microstructures of aluminium nitride (AlN, wurtzite structure) thin films on 50 μm thick stainless steel foil. The transverse piezoelectric coefficient d31,f and e31,f of 10 μm thick AlN films were estimated as -1.42 ± 0.08 pm/V and -0.48 ± 0.03 C/m 2 from a tip displacement of the piezoelectric cantilevers. Dielectric constant ε3...

Monodisperse crystalline zero-valent iron, iron-nickel, iron-palladium nanowires were synthesised using template-directed electrodeposition methods. Prior to nanowire fabrication, alumina nanotemplates with controlled pore structure (e.g. pore diameter and porosity) were fabricated by anodising high purity aluminium foil in sulphuric acid. After fabrication of alumina nanotemplates, iron, iron-...

A simple, conventional TLC method has been established for separation of clopidogrel and its hydrolytic product SR 26334, the main impurity in clopidogrel. Use of aluminium foil-backed silica gel 60F254 plates with n-heptane–tetrahydrofuran, 1:1 (v/v), as mobile phase, enabled successful separation of clopidogrel in high excess from the impurity. The separated compounds were detected at 230 nm....

Numerical simulations have been carried out in order to characterize the ultrasonic field propagation and to obtain the spatial distribution of the mechanical effect derived from it. The results have been compared with those obtained with different classical physical methods (calorimetry, aluminium foil erosion, thermal probes) and have given useful information about the influence of the presen...

The influence of three cooking methods (stewing, microwaving and Aluminium (Al) foil-baking) was evaluated on the content of intramuscular lipid and the composition of intramuscular fatty acids of Hyla rabbit. The percentage of intramuscular lipid in cooked-longissimus dorsi (LD) (dry weight %) were in the order mentioned below: microwaving > foil-baking > stewing. All treated samples showed de...
