Closure to “Preliminary Study of Surface Hydraulic Jumps” by S. Ahmed, Y. Ye, H. Liu, and N. Rajaratnam

Abstract

The authors are thankful to Bijankhan and Ferro for their discussion. We should point out that the original paper was an attempt to have a preliminary look at the surface hydraulic jumps. The depth y 1 in the original paper is indeed the perpendicular depth of the stream or jet just before the jump and it is not the vertical depth as shown in Fig. 3, the definition sketch, which is an unfortunate error. The angle of this stream with the horizontal varied from about 10°to 30°. The reason we used only one height for the weir in the experiments is because Wu and Rajaratnam (1996) have shown that the submerged flow regimes are not affected by the height of the weir over a wide range. It is interesting to find that the results of the discussers on the relative energy loss are at least approximately described by the empirical equation proposed in the original paper.References Wu, S., and N.

A novel microwave assisted reverse micelle fabrication route for Th (IV)‐MOFs as highly efficient adsorbent nanostructures with controllable structural properties to CO and CH4 adsorption: Design, and a systematic study

“…Based on the search we conducted, most studies have used classic methods to investigate the effect of synthesis parameters on adsorbent properties. [18,19] These methods increase the number of experiments, ignore the interaction between synthesis parameters, and cause a discrepancy between experimental results and theoretical models. [20,21] In general, it is difficult to find adsorbents with distinctive properties through these common studies, in addition to systematic studies, it is essential to select suitable MOF-based nanostructure.…”

Facile preparation of Cu(I) impregnated MIL‐101(Cr) and its use in a mixed matrix membrane for olefin/paraffin separation

“…CuCl particles were incorporated into porous MIL-101(Cr) through the facile reduction of the impregnated CuCl 2 in the presence of Na 2 SO 3 under mild conditions at room temperature. 15 In a glass vial, 0.1 g of powdered MIL-101(Cr) was loaded. A total of four samples of MIL-101(Cr) were prepared.…”

“…13 MOFs with modified surfaces can have specific functionality that may lead to selective interactions with the guest molecules and can improve the adsorption and selectivity. [14][15][16][17][18][19] So far, several types of chemical interactions have been reported to explain the adsorption mechanism when using modified MOFs. 17 In particular, MOFs with open metal sites such as HKUST-1 and MOF-74 show the possibility of selective interactions with olefin molecules by pcomplexation.…”

“…Besides, the direct use of Cu(I) is inefficient because of its lack of stability on loading into the porous MOFs. On the other hand, Ahmed and Jhung 15 reported Cu(I) impregnated MOFs prepared by using a reducing agent to produce Cu(I) from Cu(II). Compared to the double solvent method, this method is eco-friendly and can load a large amount of Cu(I) inside the MOFs.…”

NiCo2O4@Ni(BDC) Nano‐Porous Metal–Organic Framework as a Novel Catalyst for the Synthesis of Spiro[indene[1,2‐d]pyrimidine‐ones and Investigation of Their Antimicrobial Activities

“…Metal-organic frameworks (MOFs) are new nano-porous materials which recently take into attention as novel nanoporous materials. [21][22][23] As a highly diverse class of crystalline porous materials, MOFs have attracted great interest and a remarkable amount of MOFs structures have been designed and synthesized for various energies and environment relative applications such as gas separation and storage, ion exchange and sensors. In additions MOFs have been also used in drug delivery, catalysis, luminescent and fluorescent applications and optoelectronics materials.…”
