Abstract: The invention relates to a method for computer-implemented monitoring of a goods delivery from a seller to a buyer by using an access-restricted DLT system. The DLT system comprises a first DLT node assigned to the buyer and a second DLT node assigned to the seller. In addition, the DLT system provides at least one smart contract with program instructions for entering and checking delivery orders, order confirmations, and outgoing goods logs in the course of goods deliveries from the seller to the buyer, and for validating the goods delivery. The method comprises, for example, initialising the goods delivery in the DLT system, for example, logging the goods delivery in the DLT system and/or, for example, validating the goods delivery in the DLT system.

Abstract: A process for coordinating sample requests includes receiving a sample order over a computer based network such as the Internet, vetting the sample order to determine whether or not the intensions of the sample applicant are bona fide, permitting any bona fide sample applicant to access both an automated sample order system and a technical database. Samples may be provided to the bona fide sample applicant through an automated shipping routine. After receipt and use of the sample the sample applicant may be contacted for information regarding the performance of the sample. The sample applicants information requests and sample orders are archived in libraries accessible by the sample applicant for future reference.

Abstract: A partially hydrophobic precipitated silica having a methanol wettability of 10 to 49%, in particular with a DBP uptake on a dry basis of greater than 250 g/100 g and a mean particle size of 1 to 12 &mgr;m and/or a carbon content of 0.3 to 1.85% and/or a loss on drying of 2.6 to 10.0% and/or a pH value of 5.5 to 10.0, is prepared by mixing the amount of water-repellent agent with the precipitated silica suspension at very short residence time and low pH value, filtering off the solid substance, washing free of salt, drying, post-treating thermally and milling. The partially hydrophobic precipitated silica can be used in active substance formulations and active substance formulations of hydrolysis-sensitive substance and in defoaming agents.
