Analysis of instability of tall buildings with prestressed and waffle slabs [PDF]

Revista IBRACON de Estruturas e Materiais, 2016
ABSTRACT The construction system of prestressed flat slabs has been gaining market in Brazil, since it eliminates the use of beams, allows you to perform structures under coluns by area and reduces the cycle of concrete slabs. Thus the analysis of global stability of buildings, takes into account the effects of 2nd order, and these additional effects ...

Unlocking Multi‐Valley Energy Pockets and Interface‐Induced Phonon Filtering in InSb Thermoelectrics by Reaction‐Driven Interface Engineering

Advanced Functional Materials, EarlyView.
InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte

Advanced Functional Materials, EarlyView.
Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Why did modern post-tensioned floors flourish in the us and not in europe -a matter of tradition? [PDF]

, 2016
Unlike in Europe, prestressed concrete with post-tensioned reinforcement came to be a standard technique in building construction in the US. Kenneth Bondy has been the only one who has made a significant contribution to clarify why this occurred, by ...
