There is a reverse angle to this process. In the case of cement production, we need to burn CaCO3 to almost 900 °C to generate CaO (Calcination: CaCO₃ → CaO + CO₂). This process generated huge CO₂ directly and indirectly (due to the burning of fuel). This process can be done at a lower temperature using tribochemistry. Here we apply mechanical friction on the mineral surface (using a ball mill type of set-up), which will generate CaO at a much lower temperature (below 300 °C). Besides, there is an effort in the community to perform this process in a controlled H₂ environment directly or H from solid hydride (MgH₂, NaAlH4), which will react with CO₂ and form hydrocarbons or Carbonic acid, which have some industrial applications.
MIRACLE : Photonic Metaconcrete with Infrared RAdiative Cooling
All bodies in the Earth are in continuous exchange of energy with the sun and the atmosphere, with a net balance of power that depends on the incoming solar (short wave) and atmospheric radiation, the emitted thermal radiation, and non-radiative heat exchanges. Unfortunately, the atmosphere works like an opaque shield in most of the thermal radiation wavelengths (greenhouse effect!). Radiative cooling technology utilizes the atmospheric transparency window (8-13 μm), called the Atmospheric Window (AW), to passively dissipate heat from the Earth to outer space.
An EU project focusing on the applicability of concrete to store thermal energy. Thermal batteries can potentially be used as waste heat recyclers in the industry. It has a specific application for concreted solar power plants (CSP) where stored heat can be used to maintain a steady flow to the power grid without sunlight. As a part of the simulation team, I have studied different thermal properties of cement paste components at the molecular scale, including the heat transport mechanism that depends on the atomic arrangement and quantitative participation of different molecular groups.

Structure-Property relationship of cement constituents under various loading conditions: An atomistic approach
Structure-Property relationship of cement constituents under various loading conditions: An atomistic approach
A molecular-level investigation on the deformation behavior of individual unhydrated and hydrated cement constituents has been conducted in the framework of molecular dynamics (MD) simulation. The evolution of different mechanisms, such as stretching of bonds and deformation of angles, is studied for different structures along with interactions between individual layers of atoms. The study also includes the role of water molecules in the global deformation behavior of individual constituents. A multiscale homogenization scheme has also been developed to relate the elastic constants (of each component) obtained from molecular simulations to that of the experimentally observed elastic constant of the paste.
Seismic Vulnerability Assessment (SVA) of Existing RC building.
Seismic Vulnerability Assessment (SVA) of Existing RC building.
Development of a systematic approach for SVA of existing RC buildings. This primarily involves the development of methodologies in the framework of Monte Carlo Simulation (MCS) for detailed assessment at Level III analysis for SVA of buildings. The core of the work involves repetitive non-linear time history analysis with suitably chosen earthquake records to consider both the effect of system parameters and seismic force uncertainty, respectively. The fragility curve is obtained by Direct Monte Carlo Simulation (DMCS). Considering the computational difficulty, the Response Surface Method (RSM) is adopted to approximate the non-linear dynamic response of the building necessary to define the various damage states. The possibility of using a simple Design of Experiment (DOE) by Moving Least Squares method (MLSM) based RSM is explored to obtain an efficient computational algorithm.
