رام چندر گاندھی ۱۳؍ جون کو نئی دہلی کے انڈیا انٹر نیشنل سینٹر (IIC) میں انتقال کرگئے، یہ گاندھی جی کے پوتے، راج گوپال آچاریہ کے نواسے اور ہندوستان ٹائمز کے سابق اڈیٹر دیوداس گاندھی کے بیٹے تھے۔
ان کی تعلیم دہلی کے سنٹ اسٹیفن کالج میں ہوئی تھی جہاں وہ فلسفہ کے استاد بھی رہے، یہ ان کا خاص موضوع تھا اور اس میں دہلی یونیورسٹی اور آکسفورڈ دونوں جگہ سے ڈاکٹریٹ کی ڈگری لی تھی، برطانیہ، امریکہ اور شانتی نکیتن میں بھی فلسفہ کے استاد تھے، اس میں کئی کتابیں لکھیں۔
انہیں بابری مسجد سانحہ کا بڑا دکھ تھا، اس پر ’’سیتا کی رسوئی‘‘ کے نام سے جو کتابچہ لکھا تھا، اس میں ثابت کیا ہے کہ جو جگہ مندر کی بتائی جاتی ہے وہاں قبائلی رہتے تھے۔

Islam where considers the superiority of law, provision of justice and equity, building and purification of civilization and emphasis on the welfare of society, there ensures the first priority to humanity, peace and prosperity in the external relations. Islamic state keeps relations on the basis of equality with the world and non-Muslim citizens living within the state. On this belief and ideology Islam invites the world to set together. Islam on these principles of Islamic ideology and belief sets the foundation of collectiveness. On this principle the whole philosophy of life and living system are embraced, and the same Islamic law is the foundation of nations, on this behalf the Islamic state organized the relation with other states. In this way Islamic state on these principles keep relations with other states and within the state relations between Muslim and non-Muslim citizens on the basis of brotherhoods, equality, mercy and the principles of dignity of human being. Along with peace Islam set the principles of war which comprise ethical and prison limitations, duties and ethics amongst warrior, difference between the rights of fighters and non-fighters, treatment with pact holders and prisoners, and specified the way of better treatment with the defeated nations. He thought the manners of war to bloody man who consider everything right during the war. Islam lays great stress on equality, social justice, brotherhood and peace not only in state but across the boarders too. In this article a deep study is done to explain the relations of an Islamic state with other states. Islamic foreign policy emphasizes on the principles of equality among all the human beings and all the races and nations. Islam builds international relation on humanitarian basis.
In this thesis, we employ Density Functional Theory to gain a comprehensive insight in the physical properties (structural, vibrational, optoelectronic, photocatalytic) of MXenes, two dimensional (2D) transition metal dichalcogenides (TMDCs) and their heterostructure, aiming at extending their applicability. In MXenes, Ti2CO2, Zr2CO2, and Hf2CO2 are found to be indirect band gap semiconductors with a band gap of 0.85 eV, 1.62 eV and 1.72 eV respectively. Transition from an indirect to a direct band gap has been achieved for the biaxial tensile strain of 3% for Ti2CO2, 8% for Zr2CO2, and 13% for Hf2CO2 while the nature of the band gap remained indirect in the case of the compressive strain. The size of the band gap passed through a maximum under tensile strain and decreased monotonically under compressive strain. Analysis of Bader charge distribution show that the tensile strain decreased the transfer of charge from the Ti, Zr, and Hf atoms to the C atom. Phonon spectra exhibit that these systems are stable under a wide range of strains from compression to tension. The photocatalytic properties shows that unstrained and biaxial tensile strained Ti2CO2, Zr2CO2, and Hf2CO2 systems can be used to oxidize H2O into O2. In 2D TMDCs, MoS2, MoSe2 and MoTe2 are found to be direct band gap semiconductors. Compressive strain of 1.5% for MoS2, 1% for MoSe2, and 1.5% for MoTe2, transform their band gaps from direct to indirect. A remarkable valence band splitting and mobility of electron are also calculated and found to vary under strain. Photocatalytic properties show that unstrained and respective strained MoS2 and MoSe2 systems can oxidize H2O to O2, while MoTe2 fail to oxidize. Furthermore phonon spectra dictate that these systems are stable under both compressive and tensile strains. Mo2CO2/W2CO2 and Mo2CF2/W2CO2 out-of-plane heterostructures and their corresponding monolayers are found to be dynamically stable. Mo2CO2 and W2CO2 exhibiting the properties of two dimensional large band gap topological insulator, while Mo2CF2 and W2CF2 are metals. Topological behavior of Mo2CO2 and W2CO2 monolayers remain in Mo2CO2/W2CO2 (semiconductor-semiconductor) van der Waals heterostructure having type-II band alignment. Metal-semiconductor (Mo2CF2/W2CO2) heterostructure generating n-type Schottky contact with barrier height of 0.29 eV, due to dipole interface induced by charge rearrangement. Large absorption in visible region is observed in the Mo2CO2 than W2CO2, where blue shift is noticed in the excitonic peaks of later. A further blue shift is observed in the W2CO2/Mo2CO2, especially the part contributed by Mo2CO2.
