An application of data mining to fruit and vegetable sample identification using Gas Chromatography-Mass Spectrometry [PDF]

, 2012
One of the uses of Gas Chromatography-Mass Spectrometry (GC-MS) is in the detection of pesticide residues in fruit and vegetables. In a high throughput laboratory there is the potential for sample swaps or mislabelling, as once a sample has been pre ...

High‐Efficiency CO2 Electrolysis Enabled by Interface‐Engineered Composite Electrolytes in Ni‐Based SOEC

Advanced Science, EarlyView.
This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.
