Chemistry – A European Journal, EarlyView.We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

“Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF”
Chemistry – A European Journal, EarlyView.Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...

Resonatorless optical bistability in transmission of thin semiconductor film
Moldavian Journal of the Physical Sciences, 2005 The optical bistability phenomenon in the steady-state light transmission by a thin semiconductor film is studied taking into account two-pulse two-photon excitation of biexcitons from the ground state of the crystal.

Epilepsia, EarlyView.We examined the functional relationship between large‐scale δ‐band phase synchrony and local epileptogenic β–γ‐band amplitude bistability during NREM sleep. Increased synchrony and strong bistability characterized the epileptogenic zone, with strongest effects during N2 sleep, when seizures most frequently occur.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping
Laser &Photonics Reviews, EarlyView.A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The
