Microscale Templating of Functional Particles Using Self‐Limiting Electrospray Deposition

Small, EarlyView.
Self‐limiting electrospray deposition (SLED) uses trapped charge in a growing film to redirect incoming material and produce highly targeted and uniform sprays. Here, nanoparticles are added to sprays to functionalize pre‐patterned electrodes and other devices.

Monitoring in the Physical Channels of Optical Access Networks

Proceedings of the International Conference on Applied Innovations in IT, 2023
This research concerns the issues of monitoring in the physical channels optical access networks. This is relevant because automated diagnostic and monitoring systems in passive optical networks (PONs) are not available at the moment. The authors discuss

Method and apparatus for distributed sensing of volatiles using a long period fiber grating sensor with modulated plastic coating for environmental monitoring [PDF]

, 2010
Optical time domain reflectometry caused by absorption of a volatile or analyte into the fiber optic cladding is used as an optical nose. The fiber optics (14) are covered with a gas permeable film (44) which is patterned to leave millimeter wide gas ...

Non-calorimetric determination of absorbed power during magnetic nanoparticle based hyperthermia [PDF]

, 2018
Nanomagnetic hyperthermia (NMH) is intensively studied with the prospect of cancer therapy. A major challenge is to determine the dissipated power during in vivo conditions and conventional methods are either invasive or inaccurate.

Experimental investigation on the cracking process of primary and secondary cracks in thick concrete members

Structural Concrete, EarlyView.
Abstract The decisive reinforcement of thick concrete members is often determined by the minimum reinforcement for crack control due to restraint stresses. In contrast to the heuristic design model in Eurocode 2, a mechanically sound methodology is only provided if the deformation compatibility is considered.

Assessing the Impact of Agrivoltaic Systems on Pasture Plant and Soil Microarthropod Communities

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Agrivoltaic systems (AVS) integrate renewable energy production with agricultural use, creating novel microclimatic gradients that can affect ecosystem structure and function. However, the ecological consequences of these gradients on vegetation composition and soil biological quality remain poorly understood, particularly in pasture‐based AVS

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
