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 (open access)

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.

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

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).

Generalized molecular solvation in non-aqueous solutions by a single parameter implicit solvation scheme (open access)

Generalized molecular solvation in non-aqueous solutions by a single parameter implicit solvation scheme

Article presenting a systematic parametrization protocol for the Self-Consistent Continuum Solvation (SCCS) model resulting in optimized parameters for 67 non-aqueous solvents. The parametrization is based on a collection of ≈6000 experimentally measured partition coefficients, which were collected in the Solv@TUM database presented here. The accuracy of the optimized SCCS model is comparable to the well-known universal continuum solvation model (SMx) family of methods, while relying on only a single fit parameter and thereby largely reducing statistical noise.

Hypoxic level and duration differentially affect embryonic organ system development of the chicken (Gallus gallus)

This article investigates how key organ systems are affected by hypoxia. The results indicated that either modest hypoxia (15% O2) throughout development, or hypoxia at any level during the late stages (d 11 to 18), increased the heart and chorioallantoic membrane weight, which partly compensated for the detrimental effects of hypoxia on embryonic development.
