Ultrafast Electron Transfer Coupled with a Proton Relay in an Anisotropic Dual S‐Scheme Heterojunction for Overcoming Kinetics Mismatch in H2O2 Photosynthesis

open access: yesAdvanced Science, EarlyView.
An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

South African Unemployment in the Post-Financial Crisis Era: What are the Determinants?

open access: yesFolia Oeconomica Stetinensia, 2020
Research background: High unemployment rates are one of the greatest economic challenges facing the post-apartheid South African government over the past two decades and this problem has become more worrisome in the post-global financial crisis period.

Nonequilibrium thermal entanglement in three-qubit $XX$ model

open access: yes, 2009
Making use of the master equation and effective Hamiltonian approach, we investigate the steady state entanglement in a three-qubit $XX$ model. Both symmetric and nonsymmetric qubit-qubit couplings are considered. The system (the three qubits) is coupled

A Dual‐Piezoelectric Metal–Organic Cage/COF Z‐Scheme Heterojunction for Solar‐Mechanical Water Splitting

open access: yesAdvanced Science, EarlyView.
A dual‐piezoelectric Z‐scheme heterojunction is constructed by integrating a piezoelectric metal–organic cage (MOC‐FA3) with a β‐ketoenamine‐linked covalent organic framework (S‐COF). This design enables efficient solar‐mechanical energy conversion, achieving remarkable piezo‐photocatalytic pure water splitting for simultaneous H2 and H2O2 production ...

Mechanics of universal horizons

open access: yes, 2012
Modified gravity models such as Ho\v{r}ava-Lifshitz gravity or Einstein-{\ae}ther theory violate local Lorentz invariance and therefore destroy the notion of a universal light cone.

Depreciated Replacement Cost: Improving the Method Through a Variant Based on three Cornerstones

open access: yesReal Estate Management and Valuation, 2018
Within the scope of real estate appraisal, the Depreciated Replacement Cost method is mostly seen as a solution of last resort, when no other option is available. Nonetheless, it is ever more useful in addressing various estimation needs.

Dipolar Molecular Motor Candidates with Planar Chirality

open access: yesChemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...
