title: Efficient Biosynthesis of Phycobiliprotein in Escherichia coli
title: 大肠杆菌中藻胆蛋白的高效生物合成

description:  In this work, a pathway for SLA-PEB (a fusion protein of streptavidin and allophycocyanin that covalently binds phycoerythrobilin (PEB)) biosynthesis in E. coli was constructed using a single-expression plasmid strategy. Compared with a previous E. coli strain transformed with dual plasmids, the E. coli strain transformed with a single plasmid showed increased plasmid stability and produced SLA-PEB with a higher chromophorylation ratio. To achieve full chromophorylation of SLA-PEB, directed evolution was employed to improve the catalytic performance of lyase CpcS. In addition, the catalytic abilities of heme oxygenases from different cyanobacteria were investigated based on biliverdin IXα and PEB accumulation. Upregulation of the heme biosynthetic pathway genes was also carried out to increase heme availability and PEB biosynthesis in E. coli. Fed-batch fermentation was conducted for the strain V5ALD, which produced recombinant SLA-PEB with a chromophorylation ratio of 96.7%.

title: Connectional asymmetry of the inferior parietal lobule shapes hemispheric specialization in humans, chimpanzees, and rhesus macaques
title: Connectional asymmetry of the inferior parietal lobule shapes hemispheric specialization in humans, chimpanzees, and rhesus macaques

description: The inferior parietal lobule (IPL) is one of the most expanded cortical regions in humans relative to other primates. It is also among the most structurally and functionally asymmetric regions in the human cerebral cortex. Whether the structural and connectional asymmetries of IPL subdivisions differ across primate species and how this relates to functional asymmetries remain unclear. We identified IPL subregions that exhibited positive allometric in both hemispheres, scaling across rhesus macaque monkeys, chimpanzees, and humans. The patterns of IPL subregions asymmetry were similar in chimpanzees and humans, but no IPL asymmetries were evident in macaques. Among the comparative sample of primates, humans showed the most widespread asymmetric connections in the frontal, parietal, and temporal cortices, constituting leftward asymmetric networks that may provide an anatomical basis for language and tool use. Unique human asymmetric connectivity between the IPL and primary motor cortex might be related to handedness. These findings suggest that structural and connectional asymmetries may underlie hemispheric specialization of the human brain.

title: A pressure-calibration method of wavelength modulation spectroscopy in sealed microbial growth environment
title: A pressure-calibration method of wavelength modulation spectroscopy in sealed microbial growth environment

description: new pressure-calibration method for calibrating the reduction of second harmonic (2 f ) amplitude caused by pressure broadening effect in sealed microbial growth environment is present. The new method combines with linewidth compensation and modulation depth compensation and makes the 2 f amplitude accurately retrieve metabolic CO2 in microbial growth. In order to verify the method, a simulation experiment is developed, in which the increasing CO2 concentrationleads to the increasing pressure. Comparing with the relation between the traditional 2 f amplitude and gas concentration, there is a monotonous relation between the calibrated 2 f amplitude and CO2 concentration, particularly, a linear relation is present when the CO2 concentration is replaced with the CO2 particle number. In terms of microbial measurement, the growth of Escherichia coli is measured, and the culture bottle is sealed during the microbial growth process. The experimental results show that, comparing to the microbial growth retrieved by traditional 2 f amplitude, the calibrated 2 f amplitude can accurately retrieve microbial growth in sealed environment.

title: A Dual-Laser Sensor Based on Off-Axis Integrated Cavity Output Spectroscopy and Time-Division Multiplexing Method
title: A Dual-Laser Sensor Based on Off-Axis Integrated Cavity Output Spectroscopy and Time-Division Multiplexing Method

description: In this article, a compact dual-laser sensor based on an o-axis integrated-cavity output spectroscopy and time-division multiplexing method is reported. A complete dual-channel optical structure is developed and integrated on an optical cavity, which allows two distributed feedback (DFB) lasers operating at wavelengths of 1603 nm and 1651 nm to measure the concentration of CO2 and CH4, simultaneously. Performances of the dual-laser sensor are experimentally evaluated by using standard air (with a mixture of CO2 and CH4). The limit of detection (LoD) is 0.271 ppm and 1.743 ppb at a 20 s for CO2 and CH4, respectively, and the noise equivalent absorption sensitivities are 2.68 X 10-10 cm-1 Hz-1/2 and 3.88 X 10-10 cm-1 Hz-1/2, respectively. Together with a commercial instrument, the dual-laser sensor is used to measure CO2 and CH4 concentration over 120 h and verify the regular operation of the sensor for the detection of ambient air. Furthermore, a first-order exponential moving average algorithm is implemented as an effective digital filtering method to estimate the gas concentration.

title: Novel Fe3O4 nanoparticles-based DGT device for dissolved reactive phosphate measurement
title: Novel Fe3O4 nanoparticles-based DGT device for dissolved reactive phosphate measurement

description: Iron oxide nanoparticles (Fe3O4 NPs) aqueous suspension was prepared as a novel liquid binding phase in diffusive gradients in thin-films (DGT) device (Fe3O4-DGT) combined with inductively coupled plasma optical emission spectrophotometry (ICP-OES) for the sampling measurement of dissolved reactive phosphate (DRP) in water. The DGT uptake of DRP increased linearly with deployment time rely on the superior binding efficiency of Fe3O4 NPs toward phosphate. The adsorption mechanism of DRP on Fe3O4 NPs was illustrated through the FT-IR and XPS. Various factors on the Fe3O4-DGT performance for the sampling of DRP were taken into accounts, including initial concentration of phosphate, deployment time, pH value, ionic strength, interferences from major competitive ions and the aging effect of liquid binding phase. In the present study, the effective capacity of Fe3O4-DGT device toward DRP was approximately 105 μg of phosphate per device (15.4 μg P cm-2). Compared with phosphomolybdenum blue (PMB) method, successfully field deployments of Fe3O4-DGTs samplers in Nanfei River indicated that basic Fe3O4-DGT coupled with ICP-OES method was suitable for long-term monitoring of the DRP concentration in situ.

title: Selective sodium(I) capture by olivine FePO4@C electrode in pseudocapacitive deionization: Mechanism and application

description: Selective extraction of target ions from aqueous solutions by capacitive deionization (CDI) has gradually become a highly efficient separation technology for water desalination. For the first time, a carbon coated olivine phase iron phosphate (O-FePO4@C) composite was developed by electrochemical delithiation of olivine phase LiFePO4@C composite as a pseudocapacitive electrode to explore the selective desalting behavior towards Na+, Mg2+, and Ca2+ ions. Significantly, this work also offered a new strategy for the recycling of waste lithium iron phosphate batteries, which is killing two birds with one stone. Batch experiments reflected both excellent electrosorption capacity (61.3 mg g-1 for Na+) at 1.2 V and good cycling stability of the O-FePO4@C electrode. Cyclic voltammetry (CV) and X-ray diffraction (XRD) combined with density functional theory (DFT) simulation revealed that the electrosorption mechanism of O-FePO4@C is derived from ion intercalation for Na+ and Mg2+, and electrical double layers (EDLs) adsorption for Ca2+, respectively, which exhibited outstandingly selective sodium(I) electrosorption ability. Combining density of state (DOS) of electrons with spectroscopic analysis revealed that the intercalated ions can impact electron configuration and improve the conductivity of the electrode material. The selective desalination performance of O-FePO4@C was also confirmed by treating natural groundwater samples.
