Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

The thermal structure of small and shallow Arctic Fennoscandian lakes

Arctic, Antarctic, and Alpine Research
A continuous three-year field study, focusing on the thermal regime and the heat budget of twelve shallow Arctic lakes in northwest Finland, was conducted between 2019 and 2022.

Physical limnology of Italian lakes. 1. Relationship between morphometry and heat content

Journal of Limnology, 2002
The influence of morphometry on maximum and minimum heat content and on pluriannual heat budgets of 31 Italian lakes is analysed. The energy parameters are highly correlated with the morphometric parameters through power regressions.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

Advanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

High-Resolution Wellbore Temperature Logging Combined with a Borehole-Scale Heat Budget: Conceptual and Analytical Approaches to Characterize Hydraulically Active Fractures and Groundwater Origin

Geofluids, 2018
This work aims to provide an overview of the thermal processes that shape wellbore temperature profiles under static and dynamic conditions. Understanding of the respective influences of advection and conduction heat fluxes is improved through the use of

Seasonal heat budget of the Mediterranean Sea [PDF]

Journal of Geophysical Research: Oceans, 2005
We calculate the monthly components of the Mediterranean Sea heat budget, namely the net shortwave, net longwave, latent, sensible heat fluxes, and heat storage change, for years 1984–2000. The radiative components of the seasonal heat budget are derived by a radiation transfer model, while in most other studies bulk formulae are used.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Multidecadal shifts of the northern and southern edges of the western Pacific warm pool

Environmental Research Letters
The western Pacific warm pool (WPWP) plays a pivotal role in shaping global climate. Using observational datasets, we uncover significant multidecadal shifts in the northern and southern edges of the WPWP. Heat budget analysis based on century-long ocean

Heat budget of the central American seas

Geofísica Internacional, 1976
Se calculó el balance calórico de las áreas del Golfo de México, Corriente de Florida, Mar Caribe y Océano Pacifico Oriental, a base de observaciones de barcos durante 1911-70. La distribución de la radiación neta está dictada sobre todo por la nubosidad

The diurnal heat budget of the thermosphere [PDF]

Planetary and Space Science, 1973
Detailed numerical calculations of thermospheric heat sources and sinks are presented and their relative importance is discussed in reference to the energy balance phenomena of the neutral atmosphere. It is shown that the thermal energy available from the absorption in the Schumann-Runge continuum leading to photodissociation of O2 is by far the ...
