High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

open access: yesAdvanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Better Late than Never: Current Understanding of the Archaic Period in Central Belize

open access: yesHeritage
The Archaic period in the Maya lowlands of Mesoamerica emerged around 8000 BCE and likely lasted until about 1000 BCE; however, both the development and complex cultural adaptations representative of Archaic peoples present challenges for archaeologists.

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

open access: yesAdvanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Greek interactions with Egyptian material culture during the Archaic Period [PDF]

open access: yes, 2015
This thesis proposes that we can better understand Greek society in the Archaic Period by evaluating the purposes of their interactions with Egyptian material culture and through a greater appreciation of Egyptian political and cultural history in the ...

Late archaic hunter-gatherer lithic technology and function (chipped stone, ground stone, and fire-cracked rock)

open access: yesRevista de Arqueologia, 2017
This doctoral research highlights the complicated trajectories of hunter-gatherers by offering a case study from an understudied but rich hunter-gatherer landscape, the Late Archaic period (c. 5,000-2,000 BP) on Grand Island in Michigan’s Upper Peninsula,

New considerations on the acropolis of Butrint during the Archaic age

open access: yesGroma, 2023
The paper discusses the current state of research in relation to the archaic phases of Butrint (Southern Albania), one of the few sites of ancient Epirus with important archaeological evidence dating back to the Archaic period.

MicroRoboScope: A Portable and Integrated Mechatronic Platform for Magnetic and Acoustic Microrobotic Experimentation

open access: yesAdvanced Robotics Research, EarlyView.
This work presents the MicroRoboScope, a highly integrated, compact, and portable microrobotic experimentation platform combining electromagnetic and acoustic actuation with real‐time visual feedback into a single, end‐to‐end device. The system enables closed‐loop control and tracking algorithm experimentation within an accessible and unified hardware ...

Professionalism and the poetic persona in archaic Greece [PDF]

open access: yes, 2016
Greek poets of the archaic period, though often characterised as amateur aristocrats, could also seek to present themselves as professionals – regular practitioners of a specialist skill (τέχνη). In this capacity, the poet is understood to work primarily

Dynamic Self‐Clickable Decellularized Matrix Hydrogels for Regulating Vascularity and Enhancing Muscle Regeneration

open access: yesAdvanced Science, EarlyView.
Dynamic decellularized hydrogels are prepared using bovine decellularized small intestine submucosa (SIS) norbornene (dSIS‐NB). Bovine dSIS contained significant amounts of disulfide‐rich fibrillin‐I, enabling ‘self‐clickable’ thiol‐norbornene gelation and spatiotemporal tuning of hydrogel physicochemical properties.
