The major applications of PGMs are as catalysts in automotive industry, petroleum refining, environmental (gas remediation), industrial chemical production (e.g., ammonia production, fine chemicals), electronics, and medical fields. As the next generation energy technologies for hydrogen production, such as electrolysers and fuel cells for stationary and transport applications, become mature, the demand for PGMs is expected to further increase. Reserves and annual production of Ru, Rh, Pd, Ir, and Pt have been determined and reported. Based on currently available resources, there is around 200 years lifetime based on current demand for all PGMs, apart from Pd, which may be closer to 100 years. Annual primary production of 190 t/a for Pt and 217 t/a for Pd, in combination with recycling of 65.4 t/a for Pt and 97.2 t/a for Pd, satisfies current demand. By far, the largest demand for PGMs is for all forms of catalysis, with the largest demand in auto catalysis. In fact, the biggest driver of demand and price for Pt, Pd, and Rh, in particular, is auto emission regulation, which has driven auto-catalyst design. Recovery of PGMs through recycling is generally good, but some catalytic processes, particularly auto-catalysis, result in significant dissipation. In the US, about 70% of the recycling stream from the end-of-life vehicles is a significant source of global secondary PGMs recovered from spent auto-catalyst. The significant use of PGMs in the large global auto industry is likely to continue, but the long-term transition towards electric vehicles will alter demand profiles.

The continuous research for progressively lighter components moves the attention on the massive adoption of Al alloys. The achievement of such an ambitious goal passes through the definition of innovative manufacturing methodologies able to overcome some of the most hindering limitation of Al alloys, i.e. their poor formability at room temperature. A viable approach is based on the modification of the blank properties through a local heat treatment (to achieve an optimized spatial distribution of ductility/strength), so that the subsequent forming operation can be carried out at room temperature. The implementation of such approach relies on finite element simulations, where the use of a proper constitutive material model plays a fundamental role. In the present work an innovative methodology, already proposed by the authors in a previous research, is again adopted to enrich the characterization of a strain-hardenable Al alloy (AA5754), initially purchased in a pre-strained condition (H32), and locally annealed by means of a laser treatment: in particular, Thanks to the adoption of the DIC, the investigation of the anisotropy showed a strict correlation between the value of the Lankford parameter and the material condition reached at the end of the local treatment. The experimental data were fitted by a sigmoidal function and implemented in a modified Hill plasticity model for the simulation of the tensile test of a locally treated dogbone specimen, showing a good accordance with the experimental results.

“…Battery-operated vehicles have been advised for the reduction of CO 2 emission from the transportation sector but it is associated with the penalty of the electric density stored in the batteries and the establishment of charging infrastructure. 18,19 The swing adsorption technique used by Sharma et al 18 for capturing the CO 2 from heavy-duty internal combustion engine has integrated temperature swing absorption, Rankine cycle, heat pump, and CO 2 compression and liquefaction which requires significant modification of the engine.…”

The postcombustion CO 2 capture technology (PCC) is the topic of surplus study because it offers ease of implementation in the existing systems. To the best of the authors' knowledge, this technique has never been used for the automobile sector which has a major contribution toward anthropogenic CO 2 . In this article, experimental investigation has been carried out on the chemical solvents to determine the efficacy of capturing CO 2 from multi-pollutant diesel engine exhaust. The captured CO 2 is measured in terms of percentage by volume of the total exhaust gas from three primary amines solvents, that is, monoethanolamine (MEA), N,N-dimethylethanolamine (DMEA), and ammonia at seven brake power values, and their capture efficiencies are compared. A proposed design for the implementation of carbon capture unit in the existing heavy-duty diesel engine has also been presented with theoretical calculation on the weight of the storage tank. Energy balance analyses have been performed to determine the energy needed to regenerate the solvents. It is found that the regeneration energy required for solvents MEA, DMEA, and ammonia is 2.2, 0.7, and 1.1 kWh, respectively which is quite lower than the total energy available with exhaust gas. Experimental results show that capture efficiency at ambient conditions with absorbents MEA, DMEA, and chilled ammonia is 90.95, 57.66, and 80.08, respectively. It reveals that the PCC method can be implemented in an existing diesel engine with MEA as an efficient and safe solvent.
