Abstract: A transport container for transporting an object includes an object location to receive the object and a vacuum insulation panel (VIP) to thermally insulate the object location. A sensor unit in the VIP provides a panel condition signal that corresponds to a measurement value of a physical property of the VIP. The physical property influences temperature of the object. A short-distance transmitter unit transmits a first coding of the PCS inside the Container, a long-distance transmitter unit transmits a second coding of the PCS to a remote server for processing the PSC. The server determines a representation of an operation state of the transport container, wherein the operation state is related to the temperature of the object. The material of the VIP is classified and differentiated so that transmitting parameters depend on the material.

Abstract: A mold for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process carried out within the mold can have a lower part defining an interior volume for receiving the precursors of the porous material, wherein the interior volume defines the shape of the body to be manufactured, and at least a first opening through which the body is removable from the lower part. Surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material that is electrically dissipative and non-sticky to a gel formed from the precursors of the porous material and/or the body.
