A proposal to determine properties of the gravitropic response of plants in the absence of a complicating g-force (GTHRES) [PDF]
Gravitropic responses of oat seedlings (Avena sativa L.) were measured on Earth and in microgravity (IML-1). The seedlings were grown at 1 g either on Earth or on 1 g centrifuges.

Advanced Engineering Materials, EarlyView.Fe–12Mn–0.2C medium‐manganese steel is processed by laser‐based powder bed fusion of metals using blended as well as pre‐alloyed powder. Various scanning speeds are used to determine the influence of energy deposition rate on microstructure and mechanical properties.

Direct Natural and Artificial Aging of Aluminum Alloy AlSi10Mg After Laser Powder‐Bed Fusion
Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion of metals aluminum alloy AlSi10Mg has been directly aged. Artificial aging after natural aging is considered. The hardening potential is high for the top part of the samples as well as after short natural aging. The hardening potential is substantially reduced for the bottom part of the samples, as well as after natural aging of

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

The temporal response of bone to unloading [PDF]
Rats were suspended by their tails with the forelimbs bearing the weight load to simulate the weightlessness of space flight. Growth in bone mass ceased by 1 week in the hindlimbs and lumbar vertebrae in growing rats, while growth in the forelimbs and ...

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
