Delaying and Ignoring Trends in Marriages: A Critical Study in Hadith Context

Marriage is a preamble of human life. The human society builds its façade on the characteristics of this unit. Humanity has been granted with divine rules for a successful life. The latest version of divine rules are conveyed through Islam and presented by the Holy Prophet Muhammad of benefits everlasting and grand the declared Islam of history Early. (صلى الله عليه وسلم) these rules in all nooks and corners of life; as Qur’ān and Ḥadīth prominences the trend of in-time marriages to ensure the tangible merits of life. Qur’ān declares marriage as ‘God given relationship’, ‘order from God’, ‘A lawful manner’, ‘Firm covenant’, ‘Love and compassion’, ‘Chastity of life’, ‘Right of women and Sign of safety’ and along with it, as marriage emphasizes (صلى الله عليه وسلم) Muhammad Prophet the of traditions the depicting it a ‘Half of religion’, ‘Protection of eyes’, ‘Prevention of character from corruption’, ‘source of Devil’s desperation’ etc. Owing to this stress of in-time marriages, a Muslim society is not supposed to delay or ignore in time marriages. But in present era, the trend of delaying in making marriages or ignoring the importance of in-time marriages is observing everywhere. This delay in making in-time marriages of young generation shows the weaknesses of faith and confidence in life. It is also the cause of many physical diseases and mental disorders. It destroys the best capabilities and abilities of young force. This paper highlights the importance of timely marriages, strength of married-couple life and damages of late marriage so that the requisite of Islam to form the society on the desired shape may be fulfilled. Lastly, this article emphasizes the need to review/change the social behavior regarding late marriages it also emphasizes the need to review/change the social behavior regarding late marriages and a herald to initiate some sorts of laws for making in-time marriages in society so that prevailing damages due to late marriages can be curtailed.

Synthesis of Ln-Srxmoyoz Nanoparticles and Their Application in Photocatalysis

In this work mixed metal oxides nanoparticles were synthesized containing “Mo” and “Sr” as basic elements and lanthanides (La & Gd) were doped using sonication, sol-gel and hydrothermal methods with variation in calcination temperature and reaction time. The nanomaterials synthesized were computed theoretically and later on compared photocatalytically. MoO3 nanoparticles were synthesized using sonication and sol-gel methods for 04 hours and calcined at 03 different temperatures 250, 350 and 450 °C. To conclude the best suitable method for the synthesis of MoO3 nanoparticles were characterized using fourier transform infra-red (FTIR), thermogravimetric analysis-diffraction scanning calorimetry (TGA-DSC), scanning electron microscopy-energy dispersive X-ray (SEM-EDX) spectroscopy, high resolution transmission electron microscopy (HRTEM), dynamic laser scattering-particle size analyser (DLS-PSA), X-ray diffraction (XRD) analysis and UV-Visible spectrometer. The optical properties like band gap, extinction coefficient (K), refractive index (n), optical conductivity (ρ), dielectric functions (εr and εi) and Urbach energy (EU) were determined. The sol-gel method were concluded the better one and later on used for the synthesis of MoO3 nanoparticles with the reaction time of 10 and 24 hours. SrMoO4 nanocomposites were synthesized by varying the “Sr” and “Mo” concentration with change in reaction time of 04, 10 and 24 hours using the sol-gel method. The nanocomposites were characterized using FTIR, Raman analysis, SEM-EDX, HRTEM, DLS-PSA, XRD and UV-Visible spectrometer. The refinement parameters were calculated with the help of XRDdata using FULLPROFF and PROFEX software. The optical properties like band gap, extinction coefficient (K), refractive index (n), optical conductivity (ρ), dielectric functions (εr and εi) and Urbach energy (EU) were determined. Lanthanides (La and Gd) doped SrMoO4 nanocomposites were synthesized using hydrothermal method and characterized using FTIR, Raman analysis, SEM-EDX spectroscopy, TEM, DLS-PSA, XRD analysis and UV-Visible spectrometer. The refinement parameters were calculated with the help of XRD-data using FULLPROF and PROFEX software. The optical properties like band gap, extinction coefficient (K), refractive index (n), optical conductivity (ρ), dielectric functions (εr and εi) and Urbach energy (EU) were determined. All the synthesized nanomaterials were computed theoretically using SCM-ADF/BAND and VESTA software using Density Function Theory (DFT) principles with Kohn-Sham approach. Different parameters like change in basis set, Hubbard potential, XC-functional (LDA, GGA, Meta and Model) were run to obtain the results closet to the experimental one. Relationship between theoretical and experimental band gap was observed. Density of state (DOS) analysis was performed and contribution of elements “Mo”, “O”, “Sr”, “Gd” and “La” were observed with respect to fermi energy. MOPAC software results in the geometry and frequency optimization using semi-empirical Hamiltonians calculations with PM7 code. VESTA software gives the complete 3D structural representation of synthesized nanoparticles and nanocomposites with the detailed lattice and structural parameters. The photo-catalytic activity of all the nanoparticles and nanocomposites were done against anthropogenic organo-pollutants 2-methyl-4-nitrophenol and 2-methyl-4,6dinitrophenol. These both organo-pollutants are used in military and textile industries. The results of photocatalysis are in relation to type of metal oxide, synthesis method, synthesis conditions, change in particle size and band gap are compared with respect to percentage degradation and kvalues.
