Activated carbons (AC), known for over 3000 years, still remain the most powerful conventional adsorbents, mainly due to their highly developed porous structure and these experiments carbide derived carbons (CDCs) outperformed any other materials or method for the efficient removal of TFN -  and the results are comparable only to highly specific antibody-antigen interactions.

Adsorption of the smaller cytokine IL-6 by most of the studied carbons was noticeably higher, but demonstrated similar trends. Strictly microporous Adsorba 300^o C was clearly inefficient. However, CDCs prepared at 600 ^o C having a limited amount of mesopores (pores 2-50 nm), adsorbed 66-77 % of the cytokines initially present in the solution for 1 hr. The CDCs produced at 1200 ^o C demonstrated 97-98.5 % adsorption which is comparable with the CXV samples, capable of adsorbing ~99% . The CDCs prepared from Ti₂AlC at 800 ^o C having the most developed mesoporosity decreased IL-6 concentration by ~99.8 %; the remaining IL-6 was close to the detection limit of ELISA used.

Lesson 2 Part 1 Attributive chains (ac)

Attributive chains are compound phrases which consist of two or more nouns connecting logically with each other where the preposition «of» is absent. E.g.:

the reaction of catalysis - catalysis reaction

the solution of benzene - benzene solution.

As all compound phrases are formed in scientific literature with the help of genitive case (родительный падеж), most authors prefer to use attributive chains. To avoid the frequent repetition of the preposition «of» authors omit this preposition by transferring the word which must be after the preposition «of» at the beginning of a phrase. Let’s consider this process on the following example. At first we will translate all the words:

Горение жидкости ацетилена:

горение - combustion

жидкость - liquid

ацетилен - acetylene.

Now let’s translate this phrase using the preposition «of»: горение жидкости ацетилена - the combustion of the liquid of acetylene. Here we can see two prepositions «of». Such kind of phrase is not good for English style. To get rid (избавиться) of the excessive (чрезмерный) use of the preposition «of» we should put the word «acetylene» at the beginning. The word «acetylene» will be the first. Then after the word «acetylene» we must put the word «liquid». It will be the second word. And finally the word «combustion» will be the last one in this phrase. As a result we have the following word combination: acetylene liquid combustion.

Now let’s consider the translation of AC from English into Russian on the following example: magnesium oxide melting point.

At first of all we will translate all the words in this phrase:

magnesium - магний

oxide - оксид

m

elting point - температура плавления.

When we translate from English into Russian we should start our translation from the last word. The first word will be melting point - температура плавления, the second word will be oxide - оксид and the last word will be magnesium - магний and finally we will have the following phrase: температура плавления оксида магния.
