We demonstrate a facile method for fabricating novel 3D microfluidic channels by using two-photon-activated chemistry to locally switch the interior surface of a porous host from a hydrophobic state to a hydrophilic state. The 3D structures can be infilled selectively with water and/or hydrophobic oil with a minimum feature size of only a few micrometers. We envision that this approach may enab...

Introduction: Isidis Planitia, a Noachian impact crater infilled with Hesperian aged basalts, is located on Mars on the crustal dichotomy and is antipodal to the Tharsis rise [1]. Measuring 1400 km across and 2 km deep, it is comparable in scale and age to lunar mascons. The basin contains an interesting pattern of both radial and concentric wrinkle ridges (see Figure 1), and massive graben are...

The present study evaluates the utilization of shotcrete sandwich panel (SSP) infill and CFRP strips to strengthen reinforced concrete (RC) frames. To this end, a diagonal strip-infilled RC frame, an SSP-infilled control specimen (a bare frame) were examined as single-story specimens in terms in-plane seismic response. This work compared stiffness degradation, damping, cyclic lateral Also, avai...

Today, the subjectof a building's resistance to lateral loads is one of most important concerns structural engineers. The partitions and infilled walls are non-structural elements that due their effects on building frame. Recently, it has been observed great damage occurring walls, partitions, buildings in an earthquake-prone area. Infilled effective at increasing hardness frames, which changes...

Transport and retention of colloid tracers were evaluated in standard petrographic thin sections, prepared from saprolite (Cr horizons) formed from fractured sedimentary rocks, using epi-fluorescence microscopy. Thin sections prepared from dismantled hydrogeological columns revealed four domains of macropores with apparent apertures ranging from 1 to 500 Am. Colloid retention occurred within bo...

Anodic self-organized TiO2 nanotube layers (with different aspect ratios) were electrochemically infilled with CuInSe2 nanocrystals with the aim to prepare heterostructures with a photoelectrochemical response in the visible light. The resulting heterostructure assembly was confirmed by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray diffra...

Masonry-infilled reinforced concrete frames represent a very common construction typology across the Mediterranean countries. The presence of infills substantially modifies global seismic performances buildings in terms strength, stiffness, and energy dissipation. Although several research studies focused on overall infilled frames, modeling infill panels remains an open issue due to complex in...

Infills can highly influence the seismic response of a Reinforced Concrete (RC) building: generally speaking, their presence leads to an increase in global stiffness and strength, but their brittle behavior can result in an increase of displacement demand if a certain threshold of seismic intensity is overcome. Moreover, presence of infills often leads to a change in the collapse mechanism comp...
