Advanced Science, EarlyView.Fe3S4 crystal with the exposed [001] facet exhibits higher catalytic activity for activating peroxydisulfate (PDS) to degrade clothianidin (CLO), which can be attributed to the dissolved Fe‐induced homogeneous catalytic process; while Fe3S4 crystal with the exposed [1‐21] facet exhibits excellent catalytic stability and durability, thereby boosting the

Advanced Science, EarlyView.A flexible PDMS‐LATP polymer‐ceramic membrane creates lithium‐ion “superhighways” for rapid and selective extraction from complex brines. The amorphous PDMS matrix suppresses nonselective leakage and stabilizes the ceramic network, while LATP provides preferential Li+ conduction.

Oscillations of Suspension Bridges
Journal of Applied Mechanics, 1943Abstract The author has developed a theory of oscillations of stiffened cable systems which is applicable to the design of suspension bridges. Dealing with free oscillations in the first part of the paper the author established a system of linear differential equations with variable coefficients taking into account the horizontal ...

Aerodynamic Oscillations in Suspension Bridges
Journal of Applied Mechanics, 1948Abstract Following the failure in 1940 of the Tacoma Narrows suspension bridge by wind-driven oscillations, the need for developing in advance adequate data concerning wind speeds at which such oscillations occur became apparent. Numerous studies and experiments were undertaken on the subject, the present paper dealing with a symmetrical

AEROELASTIC STABILITY OF SUSPENSION BRIDGES
1980ABSTRACT An advanced theory on the aeroelastic stability of suspension bridges has been developed by taking into account the drag effects of the aerodynamically shaped decks. The theory includes both structural systems of suspension bridges, the classical system of hanging bridges and the new system of prestressed bridges.

Leirfjord suspension bridge, investigations of an unconventional suspension bridge solution
IABSE Congress Reports<p>In a typical single-span suspension bridge design, the stiffening girder is supported by a cross beam in the bridge tower axis. However, for the Leirfjord Bridge, a planned suspension bridge in Northern Norway that will span an 800 meter wide fjord, geological challenges necessitate deviations from traditional designs.

Dynamic Instability of Suspension Bridges
Civil-Comp Proceedings, 1991Abstract Suspension bridges are long, slender flexible structures which have the potential to be susceptible to a variety of types of wind-induced instabilities, the most serious of which are divergence (due to stationary wind forces) and flutter (due to aerodynamic forces). Flutter occurs at certain wind speeds where aerodynamic forces acting on the
