Intrinsic susceptibility and bond defects in the novel 2D frustrated antiferromagnet Ba$_{2}$Sn$_{2}$ZnCr$_{7p}$Ga$_{10-7p}$O$_{22}$ [PDF]

open access: yes, 2004
We present microscopic and macroscopic magnetic properties of the highly frustrated antiferromagnet Ba$_{2}$Sn$_{2}$ZnCr$_{7p}$Ga$_{10-7p}$O$_{22}$, respectively probed with NMR and SQUID experiments.

Pengaruh Pemberian GA3 terhadap Perkecambahan Embrio Somatik Kakao

open access: yesJurnal Tanaman Industri dan Penyegar, 2021
<p><em>Germination process of somatic embryos is one of critical steps in somatic embryogenesis. The conversion of somatic embryos into plantlets is still low and adding kinetin, ABA, NAA, and GA<sub>3</sub> to the germination medium of cacao somatic embryos may increase it. The study aimed to investigate the effect of GA<sub&

Sc2Ga2CuO7: A possible quantum spin liquid near the percolation threshold [PDF]

open access: yes, 2015
Sc2Ga2CuO7 (SGCO) crystallizes in a hexagonal structure (space group: P63/mmc), which can be seen as an alternating stacking of single and double triangular layers.

Ga$^{3+}$-substitution effects in the weak ferromagnetic oxide LaCo$_{0.8}$Rh$_{0.2}$O$_{3}$

open access: yes, 2012
Magnetization and x-ray diffraction have been measured on polycrystalline samples of LaCo$_{0.8-y}$Rh$_{0.2}$Ga$_{y}$O$_{3}$ for $0 \leq y \leq 0.15$ in order to understand the spin state of Co$^{3+}$ through the Ga$^{3+}$ substitution effect.

Cold-induced male meiotic restitution in Arabidopsis thaliana is not mediated by GA-DELLA signaling [PDF]

open access: yes, 2018
Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis.

Induction of male sterility in lettuce (Lactuca sativa L.) with GA3; influence of temperature and GA3 concentration.

open access: yesNetherlands Journal of Agricultural Science, 1978
During 1976, L. sativa 'Suzan' plants were grown in the glasshouse at constant temperatures of 17, 20 and 23 deg C, or with day and night temperatures varying between 25 and 15 deg C. Plants with flower buds 1-3 mm in length were sprayed with seven GA3 concentrations (0-400 mg/kg H2O).

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

A Theory of Service Dependency

open access: yes, 2016
Service composition has become commonplace nowadays, in large part due to the increased complexity of software and supporting networks. Composition can be of many types, for instance sequential, prioritising, non-deterministic.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition

open access: yesAdvanced Functional Materials, EarlyView.
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

open access: yesAdvanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.
