Nonlocal Metaspire: A Scalable Elastic Material Platform With Decoupled Mechanical Modes
Advanced Materials, EarlyView.Nonlocal Metaspire introduces sequential rotation to realize wider scalability in implementing complex nonlocal couplings in elastic metamaterials while suppressing unintended mode coupling. Numerical results clarify the underlying wave motions, demonstrate mode‐decoupled roton and maxon formation, and support a straightforward extension to higher ...

Parametric analysis of groundshock loading on steel plates and reinforced concrete slabs [PDF]
, 2006 Hardened underground structures are purposely constructed beneath the ground surface for additional protection. The protection and sustainability of such a structure is provided by the soil overburden, supported by the structure's roof slab, also ...

Facet‐Specific PbS Quantum Dot Passivation Using Halide Perovskites for SWIR Photodetectors
Advanced Materials Interfaces, EarlyView.PbS quantum dots (QDs) are emerging as powerful short‐wave infrared photodetectors, yet the passivation mechanism of large QDs by perovskites ‐ critical for their stability ‐ remains unexplained. Here, we unveil the ligand structure of CH3NH3PbI3 (MAPI)‐passivated 4‐nm PbS QDs using FTIR, XPS, SEM, NMR, and DFT.

Annual Review of Earth and Planetary Sciences, 2002 ▪ Abstract The subducted lithosphere is composed of a complex pattern of chemical systems that undergo continuous and discontinuous phase transformation, through pressure and temperature variations. Volatile recycling plays a major geodynamic role in triggering mass transfer, melting, and volcanism.

Advanced Materials Interfaces, EarlyView.This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...

Flexural analysis of RC rectangular slabs subjected to patch load
Alexandria Engineering Journal, 2018 Many reinforced concrete slabs are subjected to heavy concentrated loads. Deck slabs in slab/girder bridges are subjected to wheel load distributed on contact area touches the slab surface. A large number of rectangular concrete slabs were analyzed using

Modelling the structural response of reinforced concrete slabs exposed to fire: validation, sensitivity, and consequences for analysis and design [PDF]
, 2018 Structural fire design represents one important aspect of the design of reinforced concrete buildings. The work presented in this thesis seeks to elucidate the structural behaviour of reinforced concrete slabs during exposure to heating from below, as

Advanced Materials Technologies, EarlyView.Liquid metal direct writing is advanced from a technological and fundamental point. Utilizing a kinematic bed, printing on large surfaces with irregularities is enabled. Furthermore, a pressure‐driven flow during printing is discovered that affects the thickness of traces.
