چکیده

Powder diffraction is used to study thermal expansion properties of MOF-5 at moderate helium gas pressures: 1.7 bar (100-500 K) and 5-150 bar (150-300 K). The framework shows negative thermal expansion (NTE) at all pressures, but vibrational motions causing NTE are damped with increasing pressures, leading to decreased NTE.

Scrutinizing negative thermal expansion in MOF-5 by scattering techniques and ab initio calculations.

Complementary experimental techniques and ab initio calculations were used to determine the origin and nature of negative thermal expansion (NTE) in the archetype metal-organic framework MOF-5 (Zn(4)O(1,4-benzenedicarboxylate)(3)). The organic linker was probed by inelastic neutron scattering under vacuum and at a gas pressure of 175 bar to distinguish between the pressure and temperature respo...

Origin of the Exceptional Negative Thermal Expansion in Metal-Organic Framework-5 Zn4O(1,4-benzenedicarboxylate)3

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...

Effect of Twisted Tape Baffles on Pressure Drop, Fluctuation and Expansion Ratios in gas - Solid Fluidized Bed

In the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. Experimental investigation has been carried out in cylindrical column with and without twisted tapes. Twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different...

Transient thermal study of recuperative tube in tube heat exchanger operating in refrigeration system using experimental test and mathematical simulation

Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling system including counter current helically coiled tube in tube heat exchanger, expansion valve...

Acoustic phonons and negative thermal expansion in MOF-5.

The mechanism of negative thermal expansion (NTE) in MOF-5 has been studied using a rigid unit mode analysis of the phonons responsible for NTE. In addition to confirming the role of the previously proposed optic 'trampoline mode' mechanism [Lock et al., Dalton Trans., 2013, 42, 1933-2320], we have identified a new acoustic mode mechanism that makes a major contribution to the macroscopic NTE o...
