Planar constructions of gas sensors are generally considered today to be better than ceramics for the development of gas-sensing devices. These structures can be fabricated by a number of microelectronic protocols as single-sided or double-sided designs. The choice depends mostly on how to...

Volume-selective MRI using an adjustable, single-sided, portable sensor This sensor can probe the interior of samples nondestructively by collecting images and measuring relaxation and dilfusion constants, and even perform chemical analysis under conditions inaccessible to conventional NMR. MRI in axial and sagittal planes at dilferent depths of the sensitive volume and T-1-weighted contrast in a tissue sample are introduced. 

Fast, flexible, and easy-to-implement target field algorithms was presented. For a single-sided handheld NMR sensor, the algorithm yields a 640 G field homogeneous to 16 100 ppm across a 1.9cm volume located...

The sample rack is unique in that it possesses pitch both front to back and side to side. A single robot pick-up point is defined, and an optical (IR) sensor constantly monitors the pick-up point for the presence of a sample. Vials placed in the rack roll down to the pickup point, under the influence of gravity. The rack allows implementation of a novel processing scheme. 

With those single-mode reactors that do not require a minimum filling volume (CEM Discover platform temperature measurement is performed from the bottom and not from the side by an external IR sensor) even volumes as low as 50 xL can be processed [57]. With the commercially available singlemode cavities of today, the largest volumes that can be processed under sealed vessel conditions are ca 50 mL, with different vessel types being available to upscale in a linear fashion from 0.05 to 50 mL. Under open vessel conditions higher volumes (> 1000 mL) have been processed under microwave irradiation conditions, without presenting any technical difficulties as, e.g., described for the synthesis of various ionic liquids on a 2 mol scale [35].
