Tales of the Iron Bloomery
In Tales of the Iron Bloomery Bernt Rundberget argues that the ironmaking of southern Hedmark was an important basis for political developments from chiefdom to Norwegian kingdom in the period AD 700-1300.

The wolf age : the Vikings, the Anglo-Saxons and the battle for the North Sea Empire
\"The first major book on Vikings by a Scandinavian author to be published in English, The Wolf Age reframes the struggle for a North Sea empire and puts readers in the mindset of Vikings, providing new insight into their goals, values, and what they chose to live and die for. Tore Skeie (Norway's Most Important Young Historian) takes readers on a thrilling journey through the bloody shared history of England and Scandinavia, and on across early medieval Europe, from the wild Norwegian fjords to the wealthy cities of Muslim Andalusia. Warfare, plotting, backstabbing and bribery abound as Skeie skillfully weaves sagas and skaldic poetry with breathless dramatization as he entertainingly brings the world of the Vikings and Anglo-Saxons to vivid life. In the eleventh century, the rulers of the lands surrounding the North Sea are all hungry for power. To get power they need soldiers, to get soldiers they need silver, and to get silver there is no better way than war and plunder. This vicious cycle draws all the lands of the north into a brutal struggle for supremacy and survival that will shatter kingdoms and forge an empire...\"-- Provided by publisher.

The sea queen : a novel
\"Six years after The Half-Drowned King, Ragnvald Eysteinsson is now king of Sogn, but fighting battles for King Harald keeps him away from home, as he confronts treachery and navigates a political landscape that grows more dangerous the higher he rises. Ragnvald's sister Svanhild has found the freedom and adventure she craves at the side of the rebel explorer Solvi Hunthiofsson, though not without a cost. She longs for a home where her quiet son can grow strong, and a place where she can put down roots, even as Solvi's ambition draws him back to Norway's battles again and keeps her divided from her brother\"-- Provided by publisher.

Nature-inspired superwettability systems
Superwettability is a centuries-old concept that has been rediscovered in past decades, largely owing to new understanding of the mechanisms of special wetting phenomena in nature. Combining multiscale structures and surface chemical compositions is crucial to fabricate interfacial materials with superwettability. In this Review, we detail the historical development and summarize the various combined superwetting states in superwettability systems. Nature-inspired design principles of superwettable materials are also briefly introduced. Superwettability systems can be extended from 2D surfaces to 0D nanoparticles, 1D fibres and channels, and 3D integrated materials. We discuss new phenomena and the advantages that superwettability-based systems have for chemical reactions and materials fabrication, including emerging applications that utilize single extreme wetting states or that combine two extreme wetting states. Finally, we provide our perspective for future research directions.
Studying nature to reveal the mechanisms of special wetting phenomena in biological systems can effectively inspire the design and fabrication of functional interfacial materials with superwettability. In this Review, the historical development, new phenomena and emerging applications of superwettability systems are discussed.

Dynamic manipulation of droplets using mechanically tunable microtextured chemical gradients
Materials and strategies applicable to the dynamic transport of microdroplets are relevant to surface fluidics, self-cleaning materials, thermal management systems, and analytical devices. Techniques based on electrowetting, topographic micropatterns, and thermal/chemical gradients have advanced considerably, but dynamic microdroplet transport remains a challenge. This manuscript reports the fabrication of mechano-tunable, microtextured chemical gradients on elastomer films and their use in controlled microdroplet transport. Specifically, discreet mechanical deformations of these films enabled dynamic tuning of the microtextures and thus transport along surface-chemical gradients. The interplay between the driving force of the chemical gradient and the microtopography was characterized, facilitating accurate prediction of the conditions (droplet radius and roughness) which supported transport. In this work, the use of microtextured surface chemical gradients in mechano-adaptive materials with microdroplet manipulation functionality was highlighted.
Techniques to alter the surface of materials to enable transport of fluids have advanced considerably, but dynamic microdroplet transport remains a challenge. Here, the authors report the fabrication of microtextured chemical gradients on elastomer films and their use in controlled microdroplet transport.

Nanoscale fletching of liquid-like polydimethylsiloxane with single perfluorocarbons enables sustainable oil-repellency
Oil repellency is essential for enabling self-cleaning, anti-soiling and stain-repelling properties, which has broad application in industries liked textiles, healthcare and electronics. While per-and-polyfluoroalkyl substances (PFAS) exhibits strong oleophobicity, their environmental and health risks have led to prohibition on long-chain PFAS ( ≥ C
8
) and restriction on short-chain PFAS (C
4
, C
6
). However, there are few alternative materials demonstrating comparable oil repellency. Here, we introduce a novel method to fletch polydimethylsiloxane (PDMS) brushes with ultrashort PFAS (singe -CF
3
, the least toxic PFAS), achieving oil repellency similar to short-chain PFAS while drastically reducing the fluorine content. This work highlights that liquid-like molecular design, rather than chain length, can enable sustainable oil repellency, facilitating a smoother transition away from PFAS reliance.
Oil repellency using polyfluoroalkyl substances are broadly applicable, though unfavorable due to high fluorine composition. Here the authors report a polydimethylsiloxane-based system using single CF
3
groups affording oil repellency with low fluorine composition.

Spontaneous dewetting transitions of droplets during icing & melting cycle
Anti-icing superhydrophobic surfaces have been a key research topic due to their potential application value in aviation, telecommunication, energy, etc. However, superhydrophobicity is easily lost during icing & melting cycles, where the water-repellent Cassie-Baxter state turns to the sticky Wenzel state. The reversible transition during icing & melting cycle without external assistance is challenging but vital for reliable anti-icing superhydrophobic performance, such a topic has rarely been reported. Here we demonstrate a spontaneous Wenzel to Cassie-Baxter dewetting transition during icing & melting cycle on well-designed superhydrophobic surfaces. Bubbles in ice droplets rapidly impact the micro-nano valleys under Marangoni force, prompting the continuous recovery of air pockets during melting processes. We establish models to confirm the bubbles movement broadens the dewetting conditions greatly and present three criteria for the dewetting transitions. This research deepens the understanding of wettability theory and extends the design of anti-icing superhydrophobic surfaces.
Despite promising for anti-icing applications, structured superhydrophobic surfaces usually lose their hydrophobicity after a few icing/melting cycles. Here, authors investigate specific structured surfaces and air bubbles on frozen ice droplets to propose three criteria to enable dewetting transitions.
