طرحی و سنتز ترکیبات هیبریدی آلی-معدنی جدید، گستره وسیعی از تحقیقات در زمینه شیمی مواد را به خود اختصاص داده است. دندریمرها درشت مولکول های جذاب با خواص فیزیکی و شیمیایی بی نظیری هستند که که از شبکه منظم شاخه دارشان منشاء می گیرد. پلی اکسومتالات ها کلاسترهای اکسید فلزی با ساختار متنوع و خواص ساختاری جالب-توجه هستند که کاربرهای زیادی در زمینه های کاتالیست، نور، مغناطیس و پزشکی به خود اختصاص داده ...
18 polymers were characterized with respect to their friction and wear behaviour in contact with steel in environments of air and water. These were six unfilled materials, i.e. polyamide 66 (PA 66), polyoxymethyfene (POM), polyethyleneterephthalate (PETP), polyetheretherketone (PEEK), polyphenylenesuiphide (PPS) and polyethe~mide; also, the same base materials filled with poIytetrafluoroethylen...
Original and effective syntheses of crystalline silver wires and saw bundles, using reduced Keggin polyoxomolybdovanadate (POM) as mediator and reducing agent, were performed in acetonitrile at room temperature; several parameters influencing the final silver 1D-structures, with micrometric length and nanometric thickness, were varied: the nature of the POM, silver salts, vanadium(iv) source an...
PURPOSE The use of carfilzomib/pomalidomide single-agent or in combination with other agents in patients with refractory/relapsed multiple myeloma (RRMM) was not clearly clarified in clinical practice. We sought to compile the available clinical reports to better understand the efficacy and safety of carfilzomib (CFZ) and pomalidomide (POM). RESULTS Based on our research criteria, we identifi...
Polyoxometalate (POM) clusters derivatized with aniline groups exhibit distinct interactions with counterions and with each other. These interactions lead to the assembly of the clusters into chains and networks upon crystallization. Two cluster types were examined, [W(6)O(25)H(AsC(6)H(4)-4-NH(2))(2)](5-) and [Mo(12)O(46)(AsC(6)H(4)-4-NH(2))(4)](4-). The X-ray crystal structures were solved for...
The combination of pomalidomide and low-dose dexamethasone (Pom-Dex) can be safely administered to patients with end-stage relapsed/refractory multiple myeloma (RRMM). However, we observed a shorter median progression-free survival (PFS) and overall survival (OS) in these patients when characterized with adverse cytogenetics (deletion 17p and translocation [4;14]) in the Intergroupe Francophone...
This article addresses the issue of estimating probability of misclassification (PoM), when assessing the status of a water body (w.b.). The standard deviation of a monitoring data is considered a good measure of the uncertainty of the assessed w.b. status. However, when PoM is to be estimated from the biological data, a problem caused by too few monitoring data emerges. The problem is overcome...
A comparison was made of the incidence of postoperative myalgia (POM) and fasciculations when atracurium (ATR) or d-Tubocurarine (DTC) was given prior to succinylcholine (SDC) for facilitation of tracheal intubation. The subjects were 44 ASA physical status I or II outpatient females undergoing laparoscopy. They were assigned to one of three groups: Group 1 received 0.025 mg/kg ATR; Group 2 rec...
The hydrothermal synthesis of two new inorganic-organic hybrid materials in which PDA (PDA = 1,10-phenanthroline-2,9-dicarboxylate) is connected to a well-defined Keggin-type polyoxometalate anion (POM) and a Ln(III) cation (POM = [SiW12O40]4−; Ln = Eu3+ (1), Er3+ (2)), are reported. These hybrids are characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Single-c...
The past and future evolution of atmospheric composition and climate has been simulated with a version of the Max Planck Institute Earth System Model (MPI-ESM). The system consists of the atmosphere, including a detailed representation of tropospheric aerosols, the land surface, and the ocean, including a model of the marine biogeochemistry which interacts with the atmosphere via the dust and s...
