Herein, we present the intact cell matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the fingerprinting of human melanoma cancer cell lines grown on aluminium foil. To perform the MALDI-MS assay, melanoma cells were cultured on a flat and thin foil, which was directly transferred to the target plate of MALDI-MS for analysis. The influence of a wide range of cell fixat...

A series of disposable aluminium foil containers designed for cooking and packaging foods and available on the Italian market were investigated. Using different analytical techniques (near infrared (NIR), High Resolution Gas Chromatography (HRGC), gas chromatography/mass spectrometry (GC/MS)), organic substances used as lubricants in the manufacturing of the containers were detected on the alum...

Abstract The high use of aluminium foil in food and beverage packaging has caused solid waste to increase rapidly, so treatment is required. This study investigates the best concentration reactant recovery from as potash alum coagulant. Potassium hydroxide used for dissolved aluminium, sulphuric acid added form crystals. experimental result got a maximum point synthesis foil: potassium 3 M dan ...

Metal foils attract a large field of applications, e.g. in micro-technology they are being used for sensors, actors, micro-electro-mechanical systems and in medical devices. Conventional sheet metal forming processes are in principle applicable for metal foil forming. Reducing the sheet thickness to the order of micrometers, however, causes various scaling effects. Therefore, the know-how of co...

It is now possible to circumvent costly and complex cleanroom fabrication procedures to produce MHz-order acoustically-driven microfluidic platforms through the use of electrode strips cut simply from kitchen aluminium foil and pressed against piezoelectric substrates. Cleanroom deposition, lithographic patterning, and etching are entirely avoided in favor of this cut-and-place technique, which...

Penelitian ini mengukur kandungan amilum daun suruhan (Peperomia pellucida), kelor (Moringa oleifera) dan kitolod (Hippobroma longifera). Metode penelitian deskriptif adalah apa yang digunakan dalam ini. Studi menentukan nilai variabel terhubung untuk menjelaskan kejadian sosial (Sugiyono, 2018). menggunakan metode uji kadar pati kertas timah dengan bantuan betadin ada tidaknya pada daun. Berda...
