I cannot stress enough how utterly amazing this resource is. This has been the best resource I have ever brought/used for DT. As a HOD of DT it has enabled me to go so in-depth with my data analysis (I thought I was good with data before but this blew me away) and spot areas of concern so much quicker and then action areas for quick gains, which in turn has helped to improve the department results over the past 2 years. I know for a fact it would not have been possible without using this resource to support and track my learners. Even helped my non specialist line managers and SLT understand my thinking and student progress. Thank you!!!!
Thanks so much for the positive review, please do grab the updated version and watch out for the supporting presentations for the lessons in the coming months :-)
Hi there, it looks wicked but its locked... I cannot edit. I don't want to unlock all the formulas etc, but may have to to get the kids names in there and data. Please advise. Al
You can edit all the names on the student info worksheet/tab and they are transferred to every other worksheet. Hope this helps but the whole spreadsheet can be unlocked with 'gcse'

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds. Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.
Victor M. Mukhin was born in 1946 in the town of Orsk, Russia. In 1970 he graduated the Technological Institute in Leningrad. Victor M. Mukhin was directed to work to the scientific-industrial organization "Neorganika" (Elektrostal, Moscow region) where he is working during 47 years, at present as the head of the laboratory of carbon sorbents. Victor M. Mukhin defended a Ph. D. thesis and a doctoral thesis at the Mendeleev University of Chemical Technology of Russia (in 1979 and 1997 accordingly). Professor of Mendeleev University of Chemical Technology of Russia. Scientific interests: production, investigation and application of active carbons, technological and ecological carbon-adsorptive processes, environmental protection, production of ecologically clean food.

Sorbent capacity and kinetics of the adsorption process on synthetic carbons (FAS grade) and commercial coconut shell activated carbons were studied in the system activated carbon-aqueous solution of sodium dicyanoaurate(I). The effect of progressive activation of carbons on the adsorption value was analyzed. The method of moments was used to calculate the internal diffusion coefficients and show their relation to the structure of activated carbons.
