DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

STRENGTH SHRINKAGE AND CREEP OF CONCRETE IN TENSION AND COMPRESSION
Strength, shrinkage and creep of concrete in tension and compression have been determined and the relationship between those properties was studied. Direct tensile tests were applied to measure those properties in tension.

Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...
