Investigating of Susceptibility of Maharloo Lake Sediments to Wind Erosion and Determination of Dust Movement Direction [PDF]

open access: yesمدیریت بیابان, 2019
Wind erosion is one of the most important natural processes in arid and semi-arid regions. In recent years, due to lake drying, dust producing has been increased from lakes and wetlands surfaces.

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

open access: yesAdvanced Science, EarlyView.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

open access: yesAdvanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Lake bed environments, modern sedimentation and the glacial and post-glacial history of Windermere, UK [PDF]

open access: yes, 2014
Windermere, the largest natural lake in England, is a glacial ribbon lake located in the southeast of the Lake District. High resolution geophysical datasets, combined with sediment analysis, geomorphological mapping and historical research have been ...

New organic matter degradation proxies: Valid in lake systems? [PDF]

open access: yes, 2004
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

Injectable Hydrogel with Rapid Coagulation, Low Swelling, and High Burst Pressure Tolerance Properties for Long‐Term Management of Bleeding Wound

open access: yesAdvanced Science, EarlyView.
An injectable PACmC hydrogel with “rigid island‐flexible chain” architecture is developed, featuring low swelling (49.2% within 7 d), strong wet adhesion (46.5 kPa), and high burst pressure (701 mm Hg), which can achieve rapid hemostasis and long‐term sealing in rabbit and porcine models of hepatic and splenic hemorrhage.

Sub-decadal- to decadal-scale climate cyclicity during the Holsteinian interglacial (MIS 11) evidenced in annually laminated sediments [PDF]

open access: yes, 2011
To unravel the short-term climate variability during Marine Isotope Stage (MIS) 11, which represents a close analogue to the Holocene with regard to orbital boundary conditions, we performed microfacies and time series analyses on a ~3200-yr-long record ...

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Radiocarbon reservoir ages from freshwater lakes, south Georgia, sub-Antarctic: Modern analogues from particulate organic matter and surface sediments [PDF]

open access: yes, 2004
Lake sediments have the potential to preserve proxy records of past climate change. Organic material suitable for radiocarbon dating often provides age control of such proxy records.

Simultaneous Wastewater‐to‐Hydrogen Upgrading via Mechanically Driven Piezocatalysis Over Ag‐ZnO Nanorods

open access: yesAdvanced Science, EarlyView.
A piezocatalytic strategy enables simultaneous wastewater purification and hydrogen generation by harnessing mechanical energy. Complementary piezo‐induced charges are selectively directed toward oxidation and reduction pathways, achieving efficient pollutant degradation and continuous H2 evolution.
