Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine from Xylose in Escherichia coli

open access: yesAdvanced Science, EarlyView.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Draft Genome of Pseudomonas sp. Strain 11/12A, Isolated from Lake Washington Sediment. [PDF]

open access: yes, 2015
We announce here the genome sequencing of Pseudomonas sp. strain 11/12A from Lake Washington sediment. From the genome content, a versatile lifestyle is predicted but not one of bona fide methylotrophy.

Photochemical Control of Perovskite Crystal Formation at Room Temperature

open access: yesAdvanced Science, EarlyView.
The authors demonstrate how ultraviolet (UV) light can enable the crystallization of two‐dimensional (2D) perovskite crystals that are otherwise difficult to grow using conventional thermal methods. These findings are supplemented with a detailed mechanistic description for the interaction of the UV irradiation with the perovskite precursor components.

Comparative 1‐Propanol Vapor Sensing Performance of 3D MAPbBr3 and 2D (PEA)2PbBr4

open access: yesAdvanced Electronic Materials, EarlyView.
Both MAPbBr3 and (PEA)2PbBr4 perovskites exhibit exceptional sensitivity to 1‐propanol, a biomarker for lung cancer, with responses of 106 and 107 at 6000 and 7000 ppm, respectively. Notably, (PEA)2PbBr4 demonstrates superior sensitivity at low concentrations (90‐1,750 ppm).

Stability of Perovskite Indoor Photovoltaics: A Focused Review and a Call for Standardized Stability Reporting

open access: yesAdvanced Energy Materials, EarlyView.
While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...

Methylamine-assisted growth of uniaxial-oriented perovskite thin films with millimeter-sized grains

open access: yesNature Communications, 2020
Suppressing grain boundaries and defects in perovskite solar cells remains a quest to address the efficiency and stability issues. Here, the authors use methylamine gas for assisting the growth of uniaxial-oriented perovskite thin films with millimeter ...
