Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

open access: yesAdvanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Losses of sediment and phosphorus through subsurface drains in a clayey field in southern Finland [PDF]

open access: yes, 2006
Seasonal and short-term transport of eroded soil (TSS), total phosphorus (total P) and dissolved orthophosphate phosphorus (DP) via tile drains were studied using on-farm monitoring data from a clayey field under cereal ...

Measurement of phosphorus segregation in silicon at the atomic-scale using STM

open access: yes, 2003
In order to fabricate precise atomic-scale devices in silicon using a combination of scanning tunnelling microscopy (STM) and molecular beam epitaxy it is necessary to minimize the segregation/diffusion of dopant atoms during silicon encapsulation.

The characterization of recycled concrete aggregate as filter in removal of phosphorus [PDF]

open access: yes, 2020
Phosphorus (P) is one of the key nutrients that lead to eutrophication problem in surface water. However, the existing conventional wastewater treatment system to remove phosphorus is expensive and require a complex process. Therefore, a system using low

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Nitrogen and phosphorus leakage in ecological recycling agriculture [PDF]

open access: yes, 2005
In this report we quantify nitrogen and phosphorus leakage on three farms in the BERAS project. The study is based on direct measurements of nitrogen and phosphorus concentration in drainage water and water flow ...

Supervariate Gel Transforms into Various Biominerals in Salt Solutions

open access: yesAdvanced Functional Materials, EarlyView.
It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

Asymmetric Nanofiber Membranes for Simultaneous Moisture Adsorption and Rapid Catalytic Hydrolysis of Nerve Agent Simulants in Atmospheric Environments

open access: yesAdvanced Functional Materials, EarlyView.
Asymmetric nanofiber membranes are constructed for simultaneous moisture adsorption and catalytic hydrolysis of dimethyl 4‐nitrophenyl phosphate (DMNP) in a wide range of relative humidity. The membrane exhibits high moisture adsorption capacity and fast hygroscopic rate.
