Circular and square cups drawing and ironing of Ti alloy sheets by incremental press forming method [PDF]
MATEC Web of ConferencesThe low ductility of Ti–6Al–4V alloy at forming temperatures below 780°C is still a problem. Ti–6Al–IV alloy is usually hot press formed at 780 to 900°C.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Environmental and health consequences of shore power for vessels calling at major ports in India
Environmental Research Letters, 2021 To reduce local air pollution, many ports in developed countries require berthed ships to use shore-based electricity instead of burning diesel to meet their electricity requirement for loads such as lights, cargo-handling equipment, and air conditioning.

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly
Advanced Functional Materials, EarlyView.Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Local energy production scenarios for emissions reduction of pollutants in small-medium ports
Transportation Research Interdisciplinary Perspectives, 2022 Environmental impact produced by ships in ports is a relevant problem, especially when they are located close to urban areas. This paper, taking Ancona (Italy) as a case study, analyzes the CO2 (and other chemical species) emissions produced by the ...

Prospects of cold ironing as an emissions reduction option [PDF]
Transportation Research Part A: Policy and Practice, 2019 Abstract Cold ironing is the process of providing shorepower to cover the energy demands of ships calling at ports. This technological solution can eliminate the emissions of auxiliary engines at berth, resulting in a global reduction of emissions if the grid powering the ships is an environmentally friendly energy source.

The cold-work damping peak in alpha-iron
Acta Metallurgica, 1967 Abstract The cold-work damping peak in poly- and single-crystal iron specimens was studied. The essential problem on the mechanism of the cold-work peak is whether an anelasticity arises from reorientations of interstitial impurity atoms or from motions of dislocations.
