The efficiency of traditional solar cells is constrained due to the Shockley-Queisser limit, to circumvent this theoretical limit, the concept of solar thermophotovoltaics (STPVs) has been introduced. The typical design...

A new fluoro-bridged rare-earth (RE) metal−organic framework consisting of 15-connected nonanuclear and 9-connected trinuclear clusters {[RE 9 -(μ 3 -F) 14 (H 2 O) 6 ][RE 3 (μ 3 -F)(H 2 O) 3 ](HCO 2 ) 3 -(BTB) 6 }•(solvent)x 2 (RE = Ho 3+ and Gd 3+ ) was synthesized through the transformation of a dimeric complex formulated as bis(2,2′-bipyridine)tetrakis(μ-2-fluorobenzoato-O,O′)-bis(2fluorobenzoato)diRE(III) 1 with the bridging linker 1,3,5-tris(4-carboxyphenyl)benzene (H 3 BTB). The rare-earth metal ions Ho 3+ and Gd 3+ were also found to remove fluorine from other organo-fluorine compounds such as perfluorohexanoic acid (PFHxA) and perfluorooctanoic acid (PFOA), resulting in the new fluorobridged RE-MOFs.

A new rare earth based two-dimensional coordination network and a three-dimensional metal-organic framework (MOF) have been synthesized using bicinchoninic acid (BCA) and yttrium(III) ions. Yttrium dimer nodes are formed in...

The basic aim of this paper is to systematically review the corporate governance research trends in Pakistan and to give directions for future researchers in this field. The methodology adopted in this paper is “Systematic Literature Review,” 108 papers have been used from the period 2002–2020 along with 17 research theses in this study. The findings of this study show two trends in corporate governance research first one form 2008 to 2016 and the second one is from 2017 to 2020. The first trend shows that corporate governance (variables) is linked with traditional topics such as firm performance, dividend policy, capital structure, cost of capital and earnings management. The theory which is mostly used in the first corporate governance trend is the agency theory. In the second trend, corporate governance (variables) are linked with multiple issues while taking various theoretical perspectives such as risk taking, tunneling, CSR, investment portfolios, board-related issues, financial distress and much more. This paper has identified and filled the research gap by writing a comprehensive review paper of the prevailing corporate governance literature and has given directions for future researchers to consider it. To the best of researchers’ knowledge, this is the first study that has systematically reviewed and synthesized the corporate governance literature by adopting the systematic literature review methodology in Pakistan an emerging economy. It is an extensive effort for the purpose to encourage the interested researchers/scholars to add and expand their contributions to the corporate governance literature in Pakistan on the potentially identified areas of corporate governance.
