Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

Advanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Entanglement tongue and quantum synchronization of disordered oscillators

, 2013
We study the synchronization of dissipatively-coupled van der Pol oscillators in the quantum limit, when each oscillator is near its quantum ground state.

On the oscillation of impulsively damped halflinear oscillators

Proceedings of The 6'th Colloquium on the Qualitative Theory of Differential Equations (August 10--14, 1999, Szeged, Hungary) edited by: Géza Makay and László Hatvani, 1999
Summary: The authors consider the nonlinear impulsive system \[ (\phi_\beta(x'))'+\phi_\beta(x) = 0,\quad t \neq t_n, \quad x^\prime(t_n + 0) = b_n x'(t_n), \] where \(n = 1, 2 \dots \), \(\phi_\beta(u)=|u|^\beta u\) with \(\beta>0\), and \(0\leq b_n \leq 1\). They investigate the oscillatory behavior of the solutions.

Ultra‐Sensitive Short‐Wave Infrared Organic Photodetectors Enabled by a π‐Conjugation Extended Proquinoid Electron Acceptor

Advanced Functional Materials, EarlyView.
A novel proquinoid‐type electron acceptor, TQC‐4Cl, with an ultra‐narrow bandgap of 1.01 eV and spectral response beyond 1200 nm enables organic SWIR photodetectors. The optimized devices show a high EQE of 13.66% and high specific detectivity over 1012 Jones at 1200 nm under −0.5 V reverse bias with outstanding thermal stability, highlighting their ...

Entanglement of bosonic modes of nonplanar molecules

, 2009
Entanglement of bosonic modes of material oscillators is studied in the context of two bilinearly coupled, nonlinear oscillators. These oscillators are realizable in the vibrational-cum-bending motions of C-H bonds in dihalomethanes.

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

Advanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...

Unified View of Deformed Single - Mode Oscillator Algebras

, 1994
A general framework for the deformation of the single-mode oscillators is presented and all deformed single-mode oscillators are unified. The extensions of the Aric-Coon, genon, the para-Bose and the para-Fermi oscillators are proposed.

Oscillation of parabolic equations with oscillating coefficients

Hiroshima Mathematical Journal, 1994
We are concerned with the oscillatory behavior of solutions of the parabolic equation with oscillating coefficients \[ \begin{multlined} u_ t (x,t) - \left( a(t) \Delta u(x,t) + \sum^ k_{i = 1} b_ i(t) \Delta u(x,t - \sigma_ i) \right) + \\ + c \biggl( x,t, u(x,t),\;u \bigl( x, \tau_ 1(t) \bigr), \dots, u \bigl( x, \tau_ m(t) \bigr) \biggr) = f(x,t ...

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

Advanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

Clock performance as a critical parameter in navigation satellite systems [PDF]

, 1978
The high performance of available oscillators has permitted the development of invaluable navigation and geodetic satellite systems. However, still higher performance oscillators would further improve the accuracy or flexibility of the ...
