Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

open access: yesAdvanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

The ecological dichotomy of ammonia-oxidizing archaea and bacteria in the hyper-arid soils of the Antarctic Dry Valleys

open access: yes, 2014
The McMurdo Dry Valleys of Antarctica are considered to be one of the most physically and chemically extreme terrestrial environments on the Earth. However, little is known about the organisms involved in nitrogen transformations in these environments ...

Viscous Fingering of Miscible Liquids in Porous and Swellable Media for Rapid Diagnostic Tests

open access: yesBioengineering, 2018
In lateral flow and colorimetric test strip diagnostics, the effects of capillary action and diffusion on speed and sensitivity have been well studied. However, another form of fluid motion can be generated due to stresses and instabilities generated in ...

First Measurement of Ambient Air Quality on the Rural Lower Eastern Shore of Maryland

open access: yesAgronomy, 2023
Concerns about atmospheric ammonia have been expressed recently by some on the Lower Eastern Shore (LES) of Maryland, which lies between the Chesapeake Bay and the Atlantic Ocean on the Delmarva peninsula. Agriculture, seafood and tourism are responsible

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Green ammonia imports could supplement long-duration energy storage in the UK

open access: yesEnvironmental Research: Energy
There is growing recognition of the need for long-duration energy storage to cope with low frequency (i.e. seasonal to multi-annual) variability in renewable energy supplies.

Evaluation of organical fertilizers in relation to minimalization of air polution by greenhouse gases and amonia

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006
Agricultural production presents one of the biggest producers of greenhouse gases. Between the most significant belongs carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozon (O3) and hydrogen sulphide (H2S). The work deals with classification of

Air quality measurements in laying hens housing [PDF]

open access: yesMacedonian Veterinary Review, 2016
Ensuring good environmental conditions of the poultry houses can be costly for the farmers, but without it losses due to poor bird health and performance due to poor air quality can be much more detrimental to net returns.

Ammonia and Nematode Ascaroside Are Synergistic in Trap Formation in Arthrobotrys oligospora

open access: yesPathogens, 2023
Nematode-trapping (NT) fungi are natural predators of the soil living nematodes. Diverse external signals mediate the generation of predatory devices of NT fungi.
