Therefore, it shows that rehabilitation effort needs to be continuous for word-finding abilities to improve from the baseline. The studies show that verbs are harder to recall or repeat, even with rehabilitation.Other methods in treating anomic aphasia include circumlocution-induced naming therapy (CIN), wherein the patient uses circumlocution to assist with his or her naming rather than just being told to name the item pictured after given some sort of cue. Results suggest that the patient does better in properly naming objects when undergoing this therapy because CIN strengthens the weakened link between semantics and phonology for patients with anomia, since they often know what an object is used for, but cannot verbally name it.Anomia is often challenging for the families and friends of those affected by it. One way to overcome this is computer-based treatment models, effective especially when used with clinical therapy. Leemann et al. provided anomic patients with computerized-assisted therapy (CAT) sessions, along with traditional therapy sessions using treatment lists of words. Some of the patients received a drug known to help relieve symptoms of anomia (levodopa), while others received a placebo. The researchers found that the drug had no significant effects on improvement with the treatment lists, but almost all of the patients improved after the CAT sessions. They concluded that this form of computerized treatment is effective in increasing naming abilities in anomic patients.Additionally, one study researched the effects of using "excitatory (anodal) transcranial direct current stimulation" over the right temporoparietal cortex, a brain area that seems to correlate to language.
those produced as by-products in industrial processes such as the acid vat treatment (pickling) of steel):

Oxidation of Fe metal in the Laux process where nitrobenzene is treated with iron metal using FeCl2 as a catalyst to produce aniline:C6H5NO2 + 3 Fe + 2 H2O   →   C6H5NH2 + Fe3O4Oxidation of FeII compounds, e.g. the precipitation of iron(II) salts as hydroxides followed by oxidation by aeration where careful control of the pH determines the oxide produced.Reduction of Fe2O3 with hydrogen:
3Fe2O3 + H2 → 2Fe3O4 +H2OReduction of Fe2O3 with CO:
3Fe2O3 + CO → 2Fe3O4 + CO2Production of nano-particles can be performed chemically by taking for example mixtures of FeII and FeIII salts and mixing them with alkali to precipitate colloidal Fe3O4.
