Introduction: ALK-negative anaplastic large cell lymphoma (ALCL) is a CD30+ T-cell neoplasm which can sometimes harbour DUSP22 rearrangement (DUSP22-R) on 6p25.3. In the first clinical report, 5-year OS of 22 patients with DUSP22-R was 90% (Parrilla Castellar et al, Blood 2014). However, in later work from British Columbia Cancer Lymphoid database, 12 40% (Hapgood BJH 2019). Thus, prognostic im...
Abstract A new biochar was produced from pea peel residues by the dehydration process. The effect of obtained on ability to remove Cr 6+ ions aqueous solution investigated. Biochar-SO with 50% sulfuric acid. biochars were characterized Fourier transform infrared (FT-IR); Brunauer, Emmett and Teller (BET); Barrett-Joyner-Halenda (BJH); thermogravimetric analysis (TGA); differential scanning calo...
چکیده: این تحقیق را می توان به دو بخش اصلی تقسیم کرد: نانوچندسازه های پلی اکسومتالات بر پایه سیلیس و نانوچندسازه های تیتانیوم بر پایه سیلیس و کاربرد کاتالیستی آن ها. در این تحقیق، مزوپورهای سیلیسی sba-15، sba-3، و mcm-48 سنتز شدند و مزوپور sba-15 با گروه های pr-nh2 و pr-nh3+ عامل دار گردید. چهار دسته از پلی اکسومتالات ها، هتروپلی اسیدهای دارای ساختار کگین (فسفوتنگستیک اسید، فسفومولیبدیک اسید،...
In this work, an innovative method is described for the preconcentration of phosphate ions using ethylenediamine functionalized mesopor (MCM-41). Functionalized MCM-41 was synthesized and the presence of organic groups in the silica framework was demonstrated by FTIR spectrum. The amount of organic groups immobilized on silica surface was determined by elemental analysis and TGA. The functi...
We report on the synthesis, morphology, chemically and structurally of La2O3-Co3O4-ZrO2 nanostructure. The La2O3-Co3O4-ZrO2 nanostructure was synthesized by a method based on the co-precipitation. Composite powders have been characterized by XRD (X-ray diffraction), SEM (scanning electr...
V2O5/SiO2 catalyst was utilized to oxidize SO2 to SO3 species in the presence of oxygen mainly for producing sulfuric acid. For this catalyst, the active phase was a mixture of vanadium pentoxide and basic sulfate/pyrosulfate material. This active phase at the reaction temperature behaved as a liquid filling up the pores of the silica support. On the other hand, amounts of the SO3 and V5+ speci...
In this study, immobilized CuAlO2 onto the ZSM-12&35 composite was prepared and used as a photocatalyst to remove N-containing oil pollutants (Carbazole) through advanced oxidation. In this method, acetone is used as a reaction solvent that can be partially converted to fuel oxygenates compounds (Octane enhancers) through an aldol condensation reaction. Photocatalyst characterization was perfor...
اهداف: در این پژوهش کاربرد خاکستر استخوان معمولی و اصلاحشده با اکسید منگنز بهعنوان جاذب در حذف فلوراید مازاد از آب آشامیدنی مورد بررسی قرار گرفت. روشها: در این مطالعه تجربی خاکستر استخوان معمولی از پیرولیز استخوان خام در دمای 450 درجه سانتیگراد تهیه شد. اصلاح خاکستر با استفاده از ترکیبات منگنز و واکنشهای حرارتی-شیمیایی انجام و خصوصیات سطحی و مشخصات جاذبهای تهیهشده با روشهای متداول BET...
In the present study, textural and structural characterizations of chitosan bead for immobilization of alpha amylase were studied in detail by N2 adsorption–desorption, Microspore Analysis (MP), Barrett–Joyner–Halenda (BJH) plots and Field Emission Scanning Electron Microscope (FESEM) observations. Pore structure observation revealed chemical activation of chitosan bead by glutaralde...
Mesoporous hydroxyapatites were syntesized by self-assembly method using Cetyltrimethylammonium bromide (CTAB) as cationic surfactant and 1-dodecanethiol as pore expander with pore expander/surfactant mass ratio of 4.22 and synthesis temperature of 80 °C in different micellization pH. The field emission-scanning electron microscopy (FESEM), x-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) ...
