Quantifying the flexural stiffness changes in the concrete beams with externally bonded carbon fiber sheets under elevated environment temperature

Alexandria Engineering Journal
Structural strengthening solutions typically employ externally bonded reinforcement (EBR) systems with carbon fiber (CF) sheets because of these materials’ lightweight, corrosion resistance, and electromagnetic immunity.

High Oxygen Evolution Activity of Tungsten Bronze Oxides Boosted by Anchoring of Co2+ at Nb5+ Sites Accompanied by Substantial Oxygen Vacancy

Advanced Science, 2020
The participation of lattice oxygen in the oxygen evolution reaction (OER) process has been proved to be faster in kinetics than the mechanisms where only metal is involved, although activating the lattice oxygen in the traditional rigid structures ...

Innovative Farming and Building Materials from Recycled Plastics

Multidisciplinary Journal of Technical University of Mombasa, 2021
Despite the ban on use of plastic paper bags, large amounts of plastic litter still exist in our environment. Plastic bottles form a greater percentage of the litter. The growth of the consumer market for cosmetics and soft drinks which are usually packaged in plastic containers continues to give rise to plastic pollution.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Effects of temperature, pH and calcium-to-carbonate ratio on the calcium carbonate polymorphs

Discover Civil Engineering
The precipitation of calcium carbonate (CaCO3) polymorphs (calcite, vaterite, and aragonite) plays a crucial role in tailoring the physicochemical properties of construction materials during mineral carbonation.
