Estimating Global Solar Radiation from Empirical Models: An Application

European Mechanical Science, 2021
Solar radiation data are required for many applications and many areas of research. In order to achieve this, several empirical models have been suggested to predict the global solar radiation in Turkey and other countries.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration? [PDF]

The Astrophysical Journal Letters, 2018
Abstract ‘Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar system. Recently, Micheli et al. reported that ‘Oumuamua showed deviations from a Keplerian orbit at a high statistical significance. The observed trajectory is best explained by an excess radial acceleration Δa ∝ r −2 ...

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Sap flow of pecan trees in a US Southeastern orchard

Frontiers in Agronomy
Sap flow methods are widely used to estimate water use through transpiration in orchards. This study reports for the first time on pecan tree sap flow properties observed in a micro-irrigated orchard in the southeastern US in 2022 and 2023.

Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Temporal Evolution, Oscillation and Coherence Characteristics Analysis of Global Solar Radiation Distribution in Major Cities in China’s Solar-Energy-Available Region Based on Continuous Wavelet Transform

Applied Sciences
The majority of the energy required for human survival is derived either directly or indirectly from solar radiation, thus it is important to investigate the periodic fluctuations in global solar radiation over time.

Heliotropic dust rings for Earth climate engineering

, 2013
This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...
