Om mig

I did my B.Sc. (Hons.) in chemistry from the University of Wah (Pakistan), finished in 2009 and continue teaching for one year. Because of interest in Materials and nanotechnology, I have chosen Stockholm University (SU) and started with my Master’s program in Material’s Chemistry at Stockholm University and graduated in 2012. Since 2012, I have worked in the industry within the field of nanotechnology and materials for various applications such as chromatography and drug delivery. I have started my Ph.D. degree in 2018 at MMk (SU). 

Uptake of enzymes in porous silica material from ex-vivo to in-vivo, these enzymatic molecules under consideration have high relevance towards diabetes and obesity-related diseases. Capturing them can help us regulate these diseases in a non-invasive way at different stages of their progression.  

Other projects include the interaction of proteins in human saliva with different types of surface topographies over the dental prosthesis. This project will give us an understanding of the underlying mechanisms of how different material properties affect the decay of natural teeth and bacteria attaching and growing over these materials. These are industrially funded projects.

    Liquid chromophores constitute a rare but intriguing class of molecules that are in high demand for the design of luminescent inks, liquid semiconductors, and solar energy storage materials. The most common way to achieve liquid chromophores involves the introduction of long alkyl chains, which, however, significantly reduces the chromophore density. Here, strategy is presented that allows for the preparation of liquid chromophores with a minimal increase in molecular weight, using the important class of perylenes as an example. Two synergistic effects are harnessed: (1) the judicious positioning of short alkyl substituents, and (2) equimolar mixing, which in unison results in a liquid material. A series of 1-alkyl perylene derivatives is synthesized and it is found that short ethyl or butyl chains reduce the melting temperature from 278 degrees C to as little as 70 degrees C. Then, two low-melting derivatives are mixed, which results in materials that do not crystallize due to the increased configurational entropy of the system. As a result, liquid chromophores with the lowest reported molecular weight increase compared to the neat chromophore are obtained. The mixing strategy is readily applicable to other pi-conjugated systems and, hence, promises to yield a wide range of low molecular weight liquid chromophores.

    The ability to convert between molecular spin states is of utmost importance in materials chemistry. Forster-type energy transfer is based on dipole-dipole interactions and can therefore theoretically be used to convert between molecular spin states. Here, a molecular dyad that is capable of transferring energy from an excited triplet state to an excited singlet state is presented. The rate of conversion between these states was shown to be 36 times faster than the rate of emission from the isolated triplet state. This dyad provides the first solid proof that Forster-type triplet-to-singlet energy transfer is possible, revealing a method to increase the rate of light extraction from excited triplet states.

    Herein, we report on the facile synthesis of a heterogeneous copper nanocatalyst and its combination with 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) for the aerobic oxidation of alcohols to their corresponding carbonyl compounds. This low cost copper nanocatalyst was found to exhibit excellent recyclability, making it a highly attractive catalytic system from an economical and environmental point of view. Extensive characterization of the catalyst by a number of techniques revealed that it was comprised of well-dispersed Cu(I/II) nanoparticles with an average size of around 6nm.

    Herein, we describe the straightforward synthesis and thorough characterization of a magnetically-separable heterogeneous catalyst comprised of 1-3nm-sized Pd nanoparticles immobilized on a mesoporous silica-magnetite composite (Pd-0-AmP-SMC). Catalytic evaluations were conducted using Suzuki-Miyaura cross-couplings as the model reactions, for which this Pd nanocatalyst exhibited high performance in an environmentally-friendly solvent mixture. Additionally, this Pd nanocatalyst could be re-used up to five cycles without any observable loss of activity, and separation of the catalyst could be conveniently done by a magnet.

    Herein we report the synthesis of mesoporous ruthenium oxide (MP-RuO2) using a template-based approach. The catalytic efficiency of the prepared MP-RuO2 was compared to commercially available ruthenium oxide nanoparticles (C-RuO2) as heterogeneous catalysts for water oxidation. The results demonstrated superior performance of MP-RuO2 for oxygen evolution compared to the C-RuO2 with respect to recyclability, amount of generated oxygen, and stability over several catalytic runs.
