Inhibition of the Exoglucanase Cel7A by a Douglas-Fir-Condensed Tannin

open access: yes, 2018
Douglas-fir forestry residues are a potential feedstock for saccharification-based biofuels, and condensed tannins are expected to make up ∼3% of the dry mass of this feedstock. Condensed tannins are well-known for their ability to interact with proteins

Synergistic Multi‐Strategy Engineering of Temperature‐Responsive Self‐Trapped Excitons in Tin‐Based Double Perovskite Nanocrystals Enables High‐Sensitivity Fluorescence Thermometry

open access: yesLaser &Photonics Reviews, EarlyView.
Bi3+‐doped Cs2SnCl6 nanocrystals are engineered to deliver highly temperature‐responsive self‐trapped exciton emission, achieving record thermal sensitivity at elevated temperatures. A temperature‐induced dual‐STE excited state landscape enables reversible thermochromism, while a dual‐parameter calibration combining fluorescence lifetime and CIE‐y ...

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

open access: yesLaser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Rethinking Public Administration Reform: Institutional Layering of Bureaucratic, Managerial and Community Logics Over Time in Nigeria's Tax Administration

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The reform of public institutions has attracted sustained attention in both scholarship and policymaking. Increasingly, however, there is growing recognition that reforms are rarely implemented in an institutional vacuum. Instead, new reforms are layered onto existing arrangements, producing hybrid institutional landscapes shaped by prior ...
