Advanced Engineering Materials, EarlyView.A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Markovian city-scale modelling and mitigation of micro-particles from tyres [PDF]
arXiv, 2021 The recent uptake in popularity in vehicles with zero tailpipe emissions is a welcome development in the fight against traffic induced airborne pollutants. As vehicle fleets become electrified, and tailpipe emissions become less prevalent, non-tailpipe emissions (from tires and brake disks) will become the dominant source of traffic related emissions ...

Advanced Functional Materials, EarlyView.The electroplating of a CrCoNi medium‐entropy alloy is achieved using a mixture of an ionic liquid and an aqueous solution containing metal salts. The CrCoNi medium‐entropy alloy thin film exhibits high wear and corrosion resistance superior to conventional hard chromium coatings. Abstract High‐entropy alloys (HEAs) and medium‐entropy alloys (MEAs) are

Journal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023 The COVID‐19 pandemic led to a backlog of filtration material for N95 Filtering Facepiece Respirators (FFRs). An alternative face mask filter material is presented, consisting of an unsupported, nonwoven layer of uncharged polystyrene microfibers. This microfiber material meets NIOSH N95 FFR filtration and breathability requirements, demonstrates ...
