Absorption and emission modulation in a MoS2–GaN (0001) heterostructure by interface phonon–exciton coupling

Article reporting the change in the transient absorption characteristics of monolayer MoS2 and the modified PL emission characteristics in a monolayer MoS2–GaN (0001) heterostructure due to the coupling of carriers with the phonon modes and the energy exchange at the interface. The results demonstrate the relevance of interface coupling between the semiconductors for the development of optical and electronic applications.

Apparent Specific Volumes of Sucrose in Different Aqueous Cosolvent Mixtures at 298.2 K

This article explores research to determine the apparent specific volume of sucrose by measuring the density of sucrose in {cosolvent + water} mixtures at 298.2 K. The study finds that a mean apparent specific volume value of 0.632 cm³.g⁻¹ for sucrose in different aqueous-cosolvent mixtures could be adequate for practical purposes in pharmaceutical industries.

The Arabidopsis PAD4 Lipase-Like Domain Is Sufficient for Resistance to Green Peach Aphid (open access)

The Arabidopsis PAD4 Lipase-Like Domain Is Sufficient for Resistance to Green Peach Aphid

Article exploring PAD4 functions in plant defense by expressing the N-terminal PAD4 lipase-like domain (PAD4ᴸᴸᴰ) without its C-terminal EDS1-PAD4 (EP) domain. The authors show that transgenic expression of PAD4ᴸᴸᴰ in Arabidopsis is sufficient for limiting GPA infestation but not for conferring basal and effector-triggered pathogen immunity. This suggests that the C-terminal PAD4 EP domain is necessary for EDS1-dependent immune functions but is dispensable for aphid resistance. Moreover, PAD4ᴸᴸᴰ is not sufficient to interact with EDS1, indicating the PAD4-EP domain is required for stable heterodimerization. These data provide molecular evidence that PAD4 has domain-specific functions.

Ascorbate Peroxidase 1 Plays a Key Role in the Response of Arabidopsis thaliana to Stress Combination

Article conducting proteomic and metabolic analysis of Arabidopsis thaliana plants subjected to a combination of drought and heat stress. The authors identify 45 different proteins that specifically accumulated in Arabidopsis in response to the stress combination. The findings suggest that cytosolic APX1 plays a key role in the acclimation of plants to a combination of drought and heat stress.

The chemical coupling between moist CO oxidation and gas-phase potassium sulfation (open access)

The chemical coupling between moist CO oxidation and gas-phase potassium sulfation

Article discusses how the chemical coupling between moist CO oxidation and transformation of gaseous potassium salts (KCl or KOH) in the presence and absence of SO2 was investigated experimentally and through chemical kinetic modeling. Analysis of the calculations indicates that sulfation pathways in the model involving KOSO3 contribute to the overprediction, but both the thermodynamic properties and rate constants in the model involve significant uncertainties and more work is required to resolve the discrepancy.

The Crucial Role of Solvation Forces in the Steric Stabilization of Nanoplatelets (open access)

The Crucial Role of Solvation Forces in the Steric Stabilization of Nanoplatelets

Article says that the steric stability of inorganic colloidal particles in an apolar solvent is usually described in terms of the balance between three contributions: the van der Waals attraction, the free energy of mixing, and the ligand compression. The authors demonstrate that for sufficiently large nanoplatelets, solvation forces are proportional to the interacting facet area, and their strength is intrinsically tied to the softness of the ligand shell.

Development and use of a switchgrass (Panicum virgatum L.) transformation pipeline by the BioEnergy Science Center to evaluate plants for reduced cell wall recalcitrance

Article examines the creation of a transformation pipeline (TP) to produce plants with decreased recalcitrance and a laboratory information management system (LIMS) for data compilation from these plants. While many genes accepted into the TP resulted in transgenic switchgrass without modified lignin or biomass content, a group of genes with potential to improve lignocellulosic biofuel yields was identified. Results from transgenic lines targeting xyloglucan and lignin structure provide examples of the types of information available on switchgrass lines produced within BioEnergy Science Center (BESC).
