Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Detection of response to command using voluntary control of breathing in disorders of consciousness

open access: yesFrontiers in Human Neuroscience, 2014
Background: Detecting signs of consciousness in patients in a vegetative state/unresponsive wakefulness syndrome (UWS/VS) or minimally conscious state (MCS) is known to be very challenging. Plotkin et al. (2010) recently showed the possibility of using a

An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

A moderate increase of physiological CO2 in a critical range during stable NREM sleep episode: A potential gateway to REM sleep

open access: yesFrontiers in Neurology, 2012
Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

Gapped $Z_2$ spin liquid in the breathing kagome Heisenberg antiferromagnet

open access: yes, 2019
We investigate the spin-1/2 Heisenberg antiferromagnet on the kagome lattice with breathing anisotropy (i.e. with weak and strong triangular units), constructing an improved simplex Resonating Valence Bond (RVB) ansatz by successive applications (up to ...
