      Vacuum insulation panels are the state-of-the-art insulation materials that are just appearing on the market for building insulation. Silica-based VIPs with multilayered envelope structure provide low thermal conductivity rates (4–10 mW/mK) and have relatively long service lifetime of about 60 years for standard 50 × 50 cm panels with 20 mm thickness. However, VIPs are also very expensive in comparison with other insulating materials with costs running up to €2000/m3, which makes them feasible only in cases of rental costs starting at around €2400/m2.

      In the presence of acids (2M sulphuric or 2M phosphoric acid), the poisoning effect on the surface of catalyst, is lower at low temperature (60 & 70°C), this leads to higher electrical efficiency. The better stack design for acidic fuel is A5SF2, having channel length of 650mm and an open ratio 52%. Maximum power density is achieved for fuel containing sulphuric acid is 42 mW cm−2 and for phosphoric acid is 36 mW cm−2.

      Addition of engineered phase change nanomaterials to heat transfer fluids is demonstrated to provide dual advantage: (i) by improving thermal conductivity and (ii) by increasing the thermal storage capacity due to the latent heat of nanomaterials phase change. Both properties are critical for increasing the efficiency and reducing the costs of energy production at Concentrated Solar Power Plants. Ceramic shells provide chemical stability to the tin cores and also prevent nanoparticle coalescence when the cores are melted.

      An advanced core flooding apparatus is used to investigate the in situ effects on CO2 storage. Experimental flow rate reductions of 70% and 98% are observed corresponding to pressures of 2 and 4 MPa, respectively. Flow rate and injection pressure has shown to follow, y = 1.4652(x)−0.798, with respect to numerical and experimental results.

      The study presents 3D numerical modeling of ZnO/Zn reduction step in a reactor. It proposes optimal reactor design by investigating the effect of different parameters and reactor configurations on the extent of ZnO reduction. It also discusses how flow velocity, temperature distribution, and ZnO particle residence time influence the extent of reduction. The figure shows contours of zinc gas concentration (kmol/m3) inside different reactor configurations.

      Water electrolysis affected by magnetohydrodynamics and pulse potential is explored. Magnetic field affects the flow direction of bubbles during electrolysis, and pulse potential accelerates the bubbles to leave the surface of the electrode. Maximum increase of current density is about 38%.

      • DMFC degradation has two components: permanent and temporary degradation that can be recovered and determines a strong recoverable performance reduction. Temporary degradation is maximized during steady-state operation;
      • The use of operating strategies involving OCV and cathode air interruption is a key point to reduce DMFC temporary degradation;
      • An experimental methodology to calculate DMFC degradation performing operating strategies is presented.

      This work evaluates the performance of a localized solar-assisted pen heating system for brooding using a 3D computational model of the heated space. The warm air-curtained pen ensures acceptable temperature and air velocity that meet the heat requirements of 100 chicks. Results show that air supplied at 40°C is capable of delivering the desired microenvironment at bird level. The localized heating system for a prototype of 16 pens consumed one third of the energy required by conventional system.
