Wide-range tuning of trap depths in double perovskite phosphors enabling tunable NIR persistent luminescence

open access: yesAdvanced Powder Materials
Persistent Luminescence (PersL) materials, which use traps to store energy and emit photons over a long period, have found important applications in the fields of optical information storage, security labeling, and biological imaging. The trap depth is a

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Development and field evaluation of the sentinel mosquito arbovirus capture kit (SMACK)

open access: yesParasites & Vectors, 2015
Background Although sentinel animals are used successfully throughout the world to monitor arbovirus activity, ethical considerations and cross-reactions in serological assays highlight the importance of developing viable alternatives.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

open access: yesFEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

A mechanical insect trap [PDF]

open access: yes, 1935
In the course of some work at Rothamsted on the activity and abundance of insects, in which a light trap was used as a method of estimating the numbers of insects in a state of activity, it appeared advisable to have a further trapping method which did ...

MODELING OF INTERDIFFUSION AND PHASE FORMATION IN THE THIN-FILM TWO-LAYER SYSTEM OF POLYCRYSTALLINE OXIDES TITANIUM AND COBALT

open access: yesКонденсированные среды и межфазные границы, 2019
Purpose. A model of reactive interdiffusion in a bilayer system of polycrystalline oxides of two metals with moving and stationary components in each phase is proposed. The model develops Darken theory of interdiffusion in a binary system with unlimited

FLUX-TRAP REACTOR WITH ABSORBER IN THE CENTER [PDF]

open access: yes, 1958
An idealized flux-trap reactor is modified by the insertion of absorber. It is shown that, for appreciable absorption, a flux depression results, and the remaining flux is proportional to the diffusion constant D times the center flux in the nonabsorption case. This factor D just cancels the factor 1/D in the expression for this center flux so that the
