Title: “Safety Enhanced Nanomaterials for High Capacity, High Rate Capable Batteries: Applications to Li-ion to Li-Sulfur Batteries and Flow Batteries”
Li-ion and next generation batteries offer both high energy and power density, making them the technology of choice for portable electronics, power tools, and electric vehicles. Despite such promise and opportunities, current and next generation battery systems have proven to be difficult to achieve great performance at high rates, while operating them safely. In this talk, I’ll present recent development of safety enhanced nanomaterials via scalable nanomanufacturing processes, which also allow the improved performance at high rates. First, thermally stable, non-flammable, and high rate capable polymer/ceramic hybrid separators fabricated via gas-assisted electrospinning which offer superior performance at high rates with enhanced safety to Li-ion and Li-sulfur batteries will be presented. To make these batteries safter and perform better at high rates, we also devise the gel ceramic electrolyte as well as high rate capable electrodes, utilizing cost-effective graphene obtained from the water-based exfoliation process and scalable air-controlled electrospray process. Finally, we also apply this modification of separator and electrodes to flow batteries, which not only improves the capacity for energy storage systems (ESS) but also allows high power flow batteries to develop self-propelling robots in water.

Development of Chemical Recognition Function for MoS2 Field-Effect-Transistor (FET) Sensor
A miniaturized sensor suitable for operating in vivo conditions has attracted great demand for past decades. For such an application field-effect-transistor (FET) sensor, the atomically thin MoS2 channel material can be a promising candidate. Due to the thin atomic layer, the MoS2 channel can be more sensitive to the adsorption of different organic molecules when used in FET. Molecular identification using FET devices has been performed by the drain current change that can be attributed to the charge exchange or the polarization of molecules. This technique, however, has no significant chemical sensitivity to the molecules. In this talk, utilizing the MoS2-FET devices, a molecule sensor with chemical recognition capability has been developed. Visible light was injected into the deposited channel, and the electronic property of the FET observed molecular identification. In addition, π-electron molecules with broadband photo response properties, such as phthalocyanine, methylene blue, di-carbocyanine iodide, and many more organic molecules, were used as adsorbates for MoS2 channel and detected by light injection.1-3

Electrochemical Production of Sustainable Carbon-Free Fuels
The increasing demand for energy and environmental concerns has induced global efforts to find and explore alternative energy sources for fossil fuels. Electrocatalysts have been played a key role in a wide range of electrochemical energy devices such as Polymer electrolyte fuel cells, and electrolyzers . As an ideal candidate, hydrogen produced from water splitting is an attractive green approach for the next-generation energy conversion devices.
Innovative design for highly efficient and durable catalysts has been considered. Replacing noble metal or metal oxides is a promising approach to overcome high-cost and elemental scarcity, greatly hindering their widespread applications. First, I will describe our recent research on developing low-cost, efficient, and robust electrocatalysts catalysts for water splitting to store sustainable energy resources. The new Co@NC electrode shows the OER overpotential of 330 mV with an ultra-stability over the noble electrode. The long-term water electrolysis cell stability testing using alloy core-carbon shell catalysts shows over 760 h stable activity (voltage loss of 4%) and outperformed the commercial (noble) catalysts .
Electrochemical ammonia synthesis by N2 fixation has proven to be a promising alternative to the energy-consuming, befouling Haber-Bosch process. Considering the low faradaic efficiency and sluggish kinetics of nitrogen reduction reaction (NRR), it is significant to design a robust and selective catalyst. A hybrid nanocatalyst fabricated by a single-step in-situ nitridation method is a potential cost-effective electrocatalyst for NRR will be discussed . For the stable electrochemical reduction of nitric oxide (NO) to value-added chemicals such as ammonia (NH3) with high selectivity and efficiency, the catalyst design strategy is crucial to circumvent the electrocatalyst reconstruction during electroconversion. We developed a core-shell catalyst in which Ni nanoparticles are wrapped by a porous nitrogen-doped carbon shell (Ni@NC) for the stable electrosynthesis of NH3.

From Jute Genes to Genomics: Bangladesh Learns to Speak Genome
For Bangladeshis jute is linked with its pursuit for economic liberation. It is our national icon, our individuality. Many of our age-old folklore is based on the golden colored jute fibres from where the country got its maxim, Sonar Bangla. The primary use of jute fibre is in making fabrics for packaging a wide range of agricultural and industrial products that require bags, sacks, packs, and wrappings. Because of its low-cost jute is used when bulky, strong fabrics and twines resistant to stretching are required. In the backdrop of a declining acreage of jute cultivation and the phenomenal rise in the use of synthetic fibers over the past few decades the importance of research on the molecular mechanisms at work in this cash crop cannot be overemphasized. However, studies on understanding the molecular biology of jute were not undertaken until the beginning of the new millennium. Significant achievements in jute molecular biology in terms of identifying germplasm biodiversity and its utilization, genetics of important agronomic traits, molecular markers and genomics have been made in the Department of Biochemistry and Molecular Biology, Dhaka University. Besides conventional breeding methods, the biotechnologies of transgenic technology and molecular marker-assisted selection have made significant contributions to jute breeding. The first jute transformation technique was developed in this department. The assessment of germplasm variome, breeding and cultivation genomics are expected to bring revolutions in jute improvement. Whole genome sequencing of C. olitorius and C. capsularis carried out by students trained in the department has not only advanced the genetic improvement of jute but has allowed Bangladesh to become fluent in life’s molecular language as reflected in the whole genome sequencing of a number of commercially important species of the country. The researchers in the country are now harnessing the advances in omics technology and using the same for the improvement of crop yield and stress resilience.

Title: Nano-based Bio-engineered self-healing composite for future construction material
Microbiologically incorporated cementitious composite or fly ash geopolymer recuperate the activities and toughness of the construction materials are a new aspect of research work in the current era. The uses of different chemicals and additive in construction materials sometimes are environmentally unacceptable because of their health-related problems. This study has designed an eco-friendly bio-engineered technology which can be used to develop a higher strength and more durable construction material by using different hot spring bacteria. A novel thermo-stable and highly pH tolerant nano-silica leaching protein (M.W. ~ 28 kDa) isolated from a hot springs bacterium BKH2 of Bakreshwar, West Bengal has been utilized for production of high performance construction materials. The corresponding gene of the protein has been identified and cloned into E. coli and B. subtilis etc. bacterial strains to develop bio-concrete material. Improvement of compressive strength (> 30 – 40%), tensile and flexural strengths, ultrasonic pulse velocity, sulphate and chloride ions resistant, thermal stability and decrement of water absorption capacity are noted in the bacteria amended concrete/geopolymer specimens. Micro-structural analyses confirmed the formation of a novel Gehlenite (Ca2Al2SiO7) phase besides calcite deposition inside the matrices of the transformed bacteria-amended composite materials. This development significantly increases the true self-healing property and aims towards the production of greener cement-alternative for sustainable concrete or composite structures. This technology may help to reduce cement consumption and certainly minimise the Green House effect caused by cement production.
