Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Assessment of the effectiveness of prestressed NSM CFRP laminates for the flexural strengthening of RC beams [PDF]
, 2013 The flexural behavior of RC beams strengthened with prestressed near-surface-mounted (NSM) carbon-fiber-reinforced-polymer (CFRP) laminate was investigated in this paper. For this purpose, four RC beams were tested under monotonic four-point loading. One

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control
Advanced Materials, EarlyView.We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Experimental and finite element dynamic analysis of incrementally loaded reinforced concrete structures [PDF]
, 2015 This work investigates influence of damage in reinforced concrete (RC) structures on their dynamic properties through modal testing and non-linear finite element (FE) analysis. Five RC beams were designed with the fundamental flexural mode frequencies in

Progressive Collapse Analysis of RC Beams
IOSR Journal of Mechanical and Civil Engineering, 2013 This paper investigates the nonlinear static analysis for studying the behavior of Progressive failure of RC beams. Nonlinear static analysis is strongly influenced by basic inputs like stress-strain relationship of constitutive materials, P-M yield interaction and moment rotation capacity of members.

Design philosophy issues of fiber reinforced polymer reinforced concrete structures
, 2002 The conventional design philosophy for reinforced concrete (RC) relies heavily on the ductile properties of steel. These ductile properties are used as a "fuse" and conceal the large uncertainty in the determination of modes of failure caused ...
