Press Release on SINC-4, 2016

Day-2

Dated: 26 Oct-2016

The 4th Saudi International Nanotechnology Conference 2016 (SINC 2016)

Current Workshop: Nanomaterials Development for Petro-Catalytic Applications

The conference started at exactly 8:30 am with the introduction of the guests from the chairman of the day, Dr Zain Yamani. First keynote speaker, Prof Michael Graetzel (Ecole Polytechnique Federale de Lausanne', Switzerland) presented on the topic 'The advent of Perovskite Solar Cells'.  He highlighted the importance of harvesting the solar energy and converting them to useful electrical power. He mentioned the components of Perovski solar cells; cation and iodine/bromine as the anion. The second keynote speaker of the day was prof. Kang L. Wang (University of California, Los Angeles) presented on the topic "Spin Orbit Interaction Engineering for High Energy Efficiency Electronics". The headword on his presentation was 'Spintronics' which is to solve the challenges of energy dissipation in embedded systems. He discussed the recent progress in spin Orbit coupling (SOC) which results in the control of magnetic field moment which gives low voltage, low power and sub-threshold energy.

The rest of todays' conference was divided into four portions i.e. 1) nanomaterials synthesis, 2) nanoelectronics and photonics 3) Photovoltaic and energy storage and 4) Nanomaterials applications.

In the session of nanoelectronics and photonics, Abdullah Aldwayyan (KSU, KSA) presented his talk about "Perovskite -based true green coherent light emitting devices", in which he threw some light on the history, principle and basic types of perovskite. He further discussed the Quantum yield, efficiency and some future aspect of these materials. He provided the comparison between Pb PbI3 with FAPbBr3 pervoskite based on their Amplified Spontaneous Emission (ASE). Then, Prof. Farid A. Harraz (Najran university-KSA) gave talk on "Porous Si-based Nano sensors for chemical analytes by electrochemical anodization techniques." He presented overview of his research in past years on these materials and pointed the challenges and practical issues with their solutions.  He also demonstrated, history, critical current is important morphology control factors during Anodization, and the role of PSi in detection of polar and non-polar organic molecule detection. They used porous sensors as optical, SERS active substrate for analyte detection and electrical sensors. Durability and storage stability are issues they got 92 % capacitance response in 90 minutes. Dr. Ahamed Algarni (King Khalid university-KSA), presented his talk on "ZnO based and ZnO-Tungsten field emitters". Initially, he discussed some introductory aspect of ZnO based field emitters and different properties effecting factors. In the later part, he presented some his recent work on ZnO-Tungsten field emitters. Prof. M. Mustafa Hussain (KAUST-KSA) discussed some future aspects of electronics and their important applications in the modern world with healthcare devices, 3D printed small objects and plug and play smart devices. At the end of this session, Dr. Asma M. Elsharif (University of Dammam, KSA) described the role of gold in plasmonic phenomena and nature of hot electrons by giving her talk on "Vertical and horizontal gold nanorods to study the plasmonic hot electron generation".

In third session of todays' conference proceedings, photovoltaic and energy storage, Prof. Ahmad Umar (Najran University-KSA) explained about "Growth, properties and applications of semiconductor nanomaterials." He focussed on ZnO as a key engineering material due to its merits of high specific surface area, optical transparency, biocompatibility, photochemical stability and ease of fabrication. Prof. Husam Al-shareef (KAUST-KSA), had given his talk under the title, "Nanostructured electrodes and devices for energy storage applications." In his talk, he discussed his strategy to improve electrode material performance in conventional supercapacitor and micro-supercapacitor devices.  Prof. M.A. Gondal (KFUPM-KSA), a distinguished professor of Physics, gave the talk on "Synthesis and characterization of High purity nanoengineered metal oxide composites using advanced pulsed laser ablation in liquids and their applications." Here he explained about rapid, clean and facile method for synthesis of metal oxides known as pulsed laser ablation in liquids (PLAL). Then studied the composites of these metal oxides in for photovoltaic applications. Dr. Idris M. Bedja (King Saud University-KSA) expressed his views regarding "Clean energy through nanotechnology: new breakthrough of tapping solar power with perovskites". His interesting talk was how about DSSCs are considered best as low cost alternative to conventional silicon photovoltaic cells.  

In the last section, Mr Hafiz Khurram Mirza (MS student at KFUPM-KSA) talked about the processing of Alumina-CNTs composite and their water filteration applications. He showed some results regarding the membrane characterization, their pure water flux transport and their capacity to absorb cadmium heavy metal ions from aqueous medium. Dr. Jagadeesh Rajenahally from university of Rostock- Germany shared his knowledge about metal oxide based heterogenous catalyst and their effect on the overall synthesis of different chemicals. He used Fe and Co oxide based nano-catalysts prepared by pyrolysis of their parent metals on heterogenous support, which showed significant selectivity and activity. The final talk of the day was delivered by Muhammad Mansha (PhD scholar at KFUPM-KSA), on the newly developing aspect of conjugate polymers applications in the field of water splitting. He synthesised visible light photoactive polymer and tested their performance for water splitting via photoelectrochemical strategy. He obtained significant negative current indicating the hydrogen evolution reaction from water splitting.
