Calorimetric Study of Mesoporous SBA‐15 Modified for Controlled Valproic Acid Delivery

Journal of Chemistry, Volume 2013, Issue 1, 2013., 2013
SBA‐15 ordered mesoporous silica functionalized with (3‐aminopropyl)triethoxysilane (APTES) was used as the carrier for anticonvulsant drug 2‐propylpentanoic acid (valproic acid). The surface of SBA‐15 containing free silanol groups was modified with 3‐aminopropyltriethoxysilane via postsynthetic reaction.

Resting energy expenditure in patients with chronic kidney disease [PDF]

, 2008
Knowledge of resting energy expenditure is of paramount importance for the determination of energy requirements and consequently for the establishment of energy recommendations of an individual. Elevated energy expenditure, if not supplied by enough food

Synthesis of Activated Carbon Mesoporous from Coffee Waste and Its Application in Adsorption Zinc and Mercury Ions from Aqueous Solution

Journal of Chemistry, Volume 9, Issue 2, Page 938-948, 2012., 2012
We obtain activated carbons with high portion of meso pores using coffee residues as precursor for the application of adsorption of large adsorbates. Because of its natural properties, the coffee residue exhibited a large pore size. In this work, the coffee residue were impregnated with ZnCl2 and KOH, and then carbonized under the nitrogen conditions ...

Heavy Metal Ions Adsorption from Wastewater Using Activated Carbon from Orange Peel

Journal of Chemistry, Volume 9, Issue 2, Page 926-937, 2012., 2012
Activated carbon obtained from orange peel (ACOP) was synthesized and used for the removal of heavy metal ions (Cr, Cd, and Co) from aqueous solutions. Two different adsorption models were used for analyzing data. Adsorption capacities were determined: copper ions exhibit the greatest adsorption on activated carbon orange peel because of its size and ...

Avaliação de blendas de PAN/polímeros biodegradáveis por calorimetria [PDF]

Matéria (Rio de Janeiro), 2012
Blendas de copolímero de poliacrilonitrila (PAN) com polímeros biodegradáveis foram obtidas pelo método convencional da indústria plástica de processamento via extrusão. O processo de produção destes materiais em extrusora convencional era um método que até pouco tempo atrás era inviável de se produzir, devido ao fato do polímero de PAN iniciar um ...

Study of Activated Carbons by Pyrolysis of Mangifera Indica Seed (Mango) in Presence of Sodium and Potassium Hydroxide

Journal of Chemistry, Volume 9, Issue 2, Page 780-785, 2012., 2012
Activated carbons (ACs) were prepared by pyrolysis of seeds mango in presence of sodium and potassium hydroxide (chemical activities). Seeds mango from Colombian Mango cultives were impregnated with aqueous solutions of NaOH and KOH following a variant of the incipient wetness method. Different concentrations were used to produce impregnation ratios of

Determination of Energy Characteristic and Microporous Volume by Immersion Calorimetry in Carbon Monoliths

Journal of Chemistry, Volume 9, Issue 2, Page 650-658, 2012., 2012
Activated carbon monoliths disc and honeycomb type were prepared by chemical activation of coconut shell with zinc chloride at different concentrations, without using a binder. The structures were characterized by N2 adsorption at 77 K and immersion calorimetry into benzene.
