Advanced Materials, EarlyView.This work introduces an injectable mesoporous silica rod scaffold that confines lentiviral vectors to the injection site, enabling localized dendritic cell recruitment and transduction. The platform sustains antigen expression, promotes robust T‐cell activation, and enhances antitumor immunity.

Noxious gas emissions above former coal and iron mines in Lorraine due to the presence of iron sulphides [PDF]
, 2015 International audienceStudies were carried out in the iron and coal basins of Lorraine (North-East of France) which indicated that oxygen-depleted air and carbon dioxide was being emitted into built-up areas related to former mine workings ...

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors
Advanced Materials, EarlyView.A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

The enviornmental assessment of a contemporary coal mining system [PDF]
A contemporary underground coal mine in eastern Kentucky was assessed in order to determine potential off-site and on-site environmental impacts associated with the mining system in the given environmental setting. A 4 section, continuous room and pillor

The detection and tracking of mine-water pollution from abandoned mines using electrical tomography [PDF]
, 2009 Increasing emphasis is being placed on the environmental and societal impact of mining, particularly in the EU, where the environmental impacts of abandoned mine sites (spoil heaps and tailings) are now subject to the legally binding Water Framework and ...

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Improvement of the Quality of Acid Mine Dranage with Natural Zeolite with Case Study at South Sumatra [PDF]
, 2007 Some natural zeolite types have been exploited for long time to improve the quality of mine waste water. This research was to study the effect of natural zeolite from Lampung (Indonesia) to improve the quality of acid mine drainage from gold-mine in ...

The engineering geology of the Nottingham area, UK [PDF]
, 2009 Nottingham was built near a crossing point on the River Trent in the East Midlands of England. Initially, the City developed on a low sandstone hill close to the north bank of the river, which provided a secure, well-drained location above the marshes ...
