manganese metal-organic framework (mn-mof) containing mn2+ ions, benzenetricarboxylic acid (btc) and n,n-dimethylformamid (dmf) was prepared and used as catalyst for oxidation of alkenes such as 1,1-diphenylethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene to epoxides with 33-92% conversion and 75-100% selectivity and oxidation of alkanes such as fluorene, adamantane, e...

Two-dimensional (2D) metal–organic frameworks (MOFs) have emerged as intriguing 2D materials because of their specific features morphology and designable skeletons, which elicited great interest in environment remediation. In this work, MOF nanosheets are fabricated via a mixed-solvent solvothermal method, regulation strategy metal inorganic clusters on MOFs is used to construct two different w...

PolyMOFs prepared from mixtures of multivalent polymer linkers and free display tunable surface areas improved CO 2 uptake compared to native MOF-5 polyMOF-5.

Novel composites (MOF-5 and Cu-BDC) based on economically activated carbon have been developed to investigate methane adsorption capacity for ANG applications. The were synthesized by adding MOFs precursor in two different weight percent (10% 40%) commercial under solvothermal conditions (110-120°C). adsorbents characterized FT-IR, XRD, SEM, EDS, BET techniques gather information about their cr...

The metal-organic framework beryllium benzene tribenzoate (Be-BTB) has recently been reported to have one of the highest gravimetric hydrogen uptakes at room temperature. Storage at room temperature is one of the key requirements for the practical viability of hydrogen-powered vehicles. Be-BTB has an exceptional 298 K storage capacity of 2.3 wt % hydrogen. This result is surprising given that t...

BACKGROUND The Fracture Risk Assessment (FRAX) tool has been developed by the World Health Organization (WHO) to calculate 10-year probability hip fracture (HP) or major osteoporotic fracture (MOF). The objective of this study was to assess the 10-year probability of MOF and HF among a selected sample of Palestinian people. METHODS A sample of 100 subjects was studied. Dual energy X-ray absor...

Metal organic framework-5 (MOF-5)was recently suggested to possess an exceptionally large negative thermal-expansion coefficient. Our direct experimental measurement of the thermal expansion of MOF-5 using neutron powder diffraction, in the temperature range of 4 to 600 K, shows that the linear thermalexpansion coefficient is ≈−16×10−6 K−1. To understand the origin of this large negative therma...

OBJECTIVES This study aimed to investigate the anatomy of the intraorbital structures regarding to endoscopic sinus surgery and external frontal sinus surgery analyzing computer tomography (CT) scans. METHODS The CT scans of 100 patients were retrospectively evaluated. The anatomic relationships between the intraorbital structures and paranasal structures were measured using multiplanar recon...
