From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Energy from renewable sources inTurkey: Status and future direction

open access: yes, 2004
Turkey is an energy importing country. Turkey's indigenous energy sources are limited and the country is heavily dependent on the import of primary energy from abroad. More than half of the energy requirement has been supplied by imports. Non-fossil

Influence of the clamping force on the power cycling lifetime reliability of press pack IGBT sub-module

open access: yesThe Journal of Engineering, 2019
The clamping force is the most important parameter of Press Pack IGBTs (PP IGBTs) as it not only affects the electrical, thermal, and mechanical characteristic, but also the long lifetime reliability.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Two-Stage Ultraviolet Degradation of Perovskite Solar Cells Induced by the Oxygen Vacancy-Ti4+ States

open access: yesiScience, 2020
Summary: The failure of perovskite solar cells (PSCs) under ultraviolet (UV) irradiation is a serious barrier of commercial utilization. Here, a two-stage degradation process of TiO2-based PSCs is discovered under continuous UV irradiation in an inert ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Energy Planning for Turkey

open access: yes, 2004
Turkey's indigenous energy sources are limited, and the country is heavily dependent on the import of primary energy from abroad. The growth of Turkey's industry is giving rise to a substantial increase energy demand.

Corona characteristics of conductor with TiO(2) hydrophilic film subjected to DC high voltage

open access: yesThe Journal of Engineering, 2019
Water drops on the surface of conductors influence the ambient electric fields and decrease corona inception voltage. A conductor coated with TiO(2) film was developed to prevent effects of droplets.
