Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

open access: yesAdvanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

A new test method for investigating punching shear strength in Ultra High Performance Fibre Reinforced Concrete (UHPFRC) slabs [PDF]

open access: yes, 2015
Punching shear capacity of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) slabs has been the subject of a number of studies. There is, however, only limited information available on this parameter of UHPFRC without conventional reinforcement ...

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

open access: yesAdvanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Effect of cross‐linking on the mechanical properties, degree of crystallinity and thermal stability of polyethylene vitrimers

open access: yesPolymer Engineering &Science, Volume 62, Issue 12, Page 4203-4213, December 2022., 2022
Thermal and mechanical properties of polyethylene vitrimers with different cross‐linking density were investigated. The yield strength and crystallinity of the vitrimers decreased with increasing cross‐linking density following a linear relationship. Abstract Maleic anhydride‐grafted‐polyethylene was dynamically cross‐linked via reactive melt blending ...

Analysis of Flat Slab Connection System for Seismic Loads [PDF]

open access: yes, 2018
Flat slab structural systems have a large applicability due to their functional and economic advantages. As such, a good number of commercial and office buildings around many Indian metro cities, in India, have been observed to adopt flat-slab system ...

Peer-to-Peer Communication Across Network Address Translators [PDF]

open access: yesUSENIX Annual Technical Conference, April 2005 (USENIX '05), Anaheim, CA, 2006
Network Address Translation (NAT) causes well-known difficulties for peer-to-peer (P2P) communication, since the peers involved may not be reachable at any globally valid IP address. Several NAT traversal techniques are known, but their documentation is slim, and data about their robustness or relative merits is slimmer.

Enhancing Volumetric Energy Density in Lithium–Sulfur Batteries through Highly Dense, Low Tortuosity Sulfur Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
This work explores the development of highly dense sulfur electrodes with a vascular pore network and low tortuosity using a shear‐force densification method. The study investigates how this innovative approach improves electrode performance, enhancing both volumetric energy density and cycling stability for lithium─sulfur batteries.
