GPT-assisted learning of structure-property relationships by graph neural networks: Application to rare-earth doped phosphors [PDF]

open access: yes, 2023
Applications of machine learning techniques in materials science are often based on two key ingredients, a set of empirical descriptors and a database of a particular material property of interest. The advent of graph neural networks, such as the Crystal Graph Convolutional Neural Network (CGCNN), demonstrates the possibility of directly mapping the ...

Chemical Pressure and Physical Pressure in BaFe_2(As_{1-x}P_{x})_2 [PDF]

open access: yesJ. Phys. Soc. Jpn. 79, 123706 (2010), 2010
Measurements of the superconducting transition temperature, T_c, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous substitution in BaFe_2(As_{1-x}P_x)_2. The pressure dependence of unsubstituted BaFe_2As_2, phosphorous concentration dependence of BaFe_2(As_{1-x}P_x)_2, as well as the ...

The Chemistry of Levulinic Acid: Its Potential in the Production of Biomass‐Based Chemicals

open access: yesAdvanced Synthesis &Catalysis, Volume 366, Issue 23, Page 4846-4888, December 3, 2024.
Abstract Biomass has been identified as the ultimate sustainable resource for all carbon‐based consumer products of the chemical industries in the future. Its catalytic conversion leads to the formation of various platform chemicals that could partially or even fully replace the fossil‐based building blocks that have been currently used in synthetic ...

Interplay between multiple scattering, emission, and absorption of light in the phosphor of a white light-emitting diode [PDF]

open access: yesOptics Express 22, 8190-8204 (2014), 2013
We study light transport in phosphor plates of white light-emitting diodes (LEDs). We measure the broadband diffuse transmission through phosphor plates of varying YAG:Ce$^{3+}$ density. We distinguish the spectral ranges where absorption, scattering, and re-emission dominate.

Specificity Effects of Amino Acid Substitutions in Promiscuous Hydrolases: Context‐Dependence of Catalytic Residue Contributions to Local Fitness Landscapes in Nearby Sequence Space

open access: yesChemBioChem, 2017
Catalytic promiscuity can facilitate evolution of enzyme functions—a multifunctional catalyst may act as a springboard for efficient functional adaptation.

The genome‐wide response of Dermatophagoides pteronyssinus to cystatin A, a peptidase inhibitor from human skin, sheds light on its digestive physiology and allergenicity

open access: yesInsect Molecular Biology, Volume 33, Issue 6, Page 662-677, December 2024.
The genome of Dermatophagoides pteronyssinus was screened for genes encoding peptidases (n = 320), glycosylases (n = 77), lipases and esterases (n = 320), peptidase inhibitors (n = 65) and allergen‐related proteins (n = 52). Ingestion of cystatin A caused the regulation of cysteine endopeptidases and glycosylases, genes acquired by horizontal gene ...

Surface phosphatase activities on roots of Pakistani wheat cultivars [PDF]

open access: yes, 1994
A study of the surface phosphatase activity of different wheat cuhivar roots was carried out, using two substrates, p-nitrophenyl phosphate (pNPP) and 4- methylumbellferyl phosphate (4-MUP), and different pH values ranging from 3 to 10.0.

Stacking dependence of carrier transport properties in multilayered black phosphorous [PDF]

open access: yesJ. Phys.: Condens. Matter 28 (2016) 075001 (10pp), 2015
We present the effect of different stacking orders on carrier transport properties of multi-layer black phosphorous. We consider three different stacking orders AAA, ABA and ACA, with increasing number of layers (from 2 to 6 layers). We employ a hierarchical approach in density functional theory (DFT), with structural simulations performed with ...

Effects of guanidino acetic acid and betaine supplementation on growth, dietary nutrient digestion and intestinal creatine metabolism in sheep

open access: yesVeterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Dietary supplementation of rumen‐protected betaine on top of guanidino acetic acid in sheep diets can improve the apparent digestibility of ether extract, phosphorus and creatine levels in small intestinal mucosal tissues. Additionally, supplemental feeding of rumen‐protected betaine and guanidino acetic acid may promote growth and development of sheep
