Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Membrane‐Penetrating Molecular Device Based on a Triplex Containing Acyclic L‐Threoninol Nucleic Acid Functionalized with Cholesterol

open access: yesAngewandte Chemie, EarlyView.
A membrane‐penetrating molecular device composed of triplex containing cholesterol‐modified acyclic L‐threoninol nucleic acid (L‐aTNA) was achieved. This device is applied to a photo‐triggered signal transduction system functioning on giant unilamellar vesicles. Abstract Membrane‐penetrating molecular devices are valuable biological tools.

A Compact, Self‐Recovering Wire Electrode Electrohydrodynamic Pump for High‐Speed McKibben Artificial Muscle Actuation

open access: yesAdvanced Intelligent Systems, EarlyView.
A compact and self‐recovering wire electrode electrohydrodynamic pump achieves high pressure, fast flowrate, and automatic recovery after dielectric discharge breakdowns. The pump delivers twice the power density of previous designs, and when integrated with a McKibben artificial muscle, enables tenfold faster actuation, offering a lightweight, silent,

Expanding current understanding of the function, style and chronology of Grooved Ware from the A9 Dualling

open access: yesProceedings of the Society of Antiquaries of Scotland, 2022
In 2018 on behalf of Transport Scotland AOC Archaeology Group undertook archaeological investigations in advance of the construction of the 9.5km A9 Dualling: Luncarty to Pass of Birnam. Six archaeological sites were excavated, revealing evidence of activity spanning the Early Neolithic to the early medieval period.

GROOVED WARE FEASTING IN YORKSHIRE: LATE NEOLITHIC ANIMAL CONSUMPTION AT RUDSTON WOLD

Oxford Journal of Archaeology, 2011
SummaryWe consider (a) feasting, and (b) the formal deposition of feasting detritus, with regard to the Late Neolithic pits on Rudston Wold. Pigs are common, as in most Grooved Ware assemblages, but we suggest that cattle may have played a proportionately greater role in eastern and northern England.
