Described is a solid body formed with Si, Al, Ca, O and at least one of Na and K, said body exhibiting in the 27Al MAS NMR spectrum a signal additional to the 27Al MAS NMR spectrum of pure calcium aluminate, with a chemical shift sited between that of the main peak of calcium aluminate and the peak next upfield to the main peak of calcium aluminate. Possible uses of the solid body include use as a building material with aggregates, as a coating, as an adhesive for joining two components for sanitary ceramic units, for high-temperature applications, for renovating existing edifices, especially for underwater renovation, for the erection and/or repair of built structures, particularly when high compressive strengths are needed or chemically aggressive conditions arise. It can be produced by bringing waterglass, sodium hydroxide and/or potassium hydroxide, calcium aluminate, one or more aggregates and optionally water, especially sea water, into contact, even at temperatures below 0°C without heating.

The invention relates to a method and to a device for determining the state of charge (SOC) of a rechargeable battery (106) of a specified battery type or a parameter physically related thereto, in particular a remaining charge amount Q contained in the battery, the method operating by means of a voltage-controlled battery model (102), which is parameterized for the battery (106) in question or a corresponding battery type. It is merely necessary to measure the battery voltage Umess and to provide said battery voltage to the battery model (102) as an input variable. The invention further relates to a method and to a device for determining the state of health (SOH) of a battery (102), wherein the battery model (102) also used to determine the SOC provides a modeled battery current Imod. Modeled charge amounts during charging and discharging phases of the battery (106) can be determined from said modeled battery current and can be compared with measured charge amounts, which are determined from the measured battery current Imess. Because the battery model (102) does not age, the SOH of the battery can thereby be determined.
The invention relates to the field of transporting flat substrates such as silicon substrates. In particular, the invention relates to particularly protective and continuous transport of such substrates. The method according to the invention is used to transport a vertically aligned flat substrate (1) comprising two flat sides in a transport direction inside a transport channel (2) that is at least partially filled with a liquid medium (F), wherein said liquid medium (F) flows against at least one of the flat sides of the substrate (1) and has a supporting component, which lifts the sum of the weight and buoyancy force of the substrate (1), and an advancing component, which is directed in the transport direction, so that the substrate (1) is supported and transported without mechanical aids. The device according to the invention comprises a transport channel (2) for accommodating a liquid medium (F) and a substrate (1) to be guided in vertical alignment within said medium (F), wherein the transport channel (2) has inflow openings (5) in the walls (3, 4).
