Synthesis and characterization of spherical amorphous alumo-silicate nanoparticles using RF thermal plasma method [PDF]
, 2013 The RF thermal plasma synthesis route was used for the preparation of alumo-silicate spherical particles. Homogeneous solid mixtures of raw materials (Al2O3, SiO2 and KOH) were used as precursors.

Advanced Functional Materials, EarlyView.Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

Precision atomic gravimeter based on Bragg diffraction [PDF]
, 2012 We present a precision gravimeter based on coherent Bragg diffraction of freely falling cold atoms. Traditionally, atomic gravimeters have used stimulated Raman transitions to separate clouds in momentum space by driving transitions between two internal ...

Geothermal resources research in a granitic basement – the Braga area case study (NW Portugal)
European Geologist, 2022 Geothermal resources are increasingly being considered as a strategic alternative in energy production, especially with the latest geopolitical developments. The densely populated Braga region, in NW Portugal, is endowed with a geostructural setting that

Advanced Functional Materials, EarlyView.Tabular foundation model interrogates the synthetic likelihood of metal−organic frameworks. Abstract Metal–organic frameworks (MOFs) are celebrated for their chemical and structural versatility, and in‑silico screening has significantly accelerated their discovery; yet most hypothetical MOFs (hMOFs) never reach the bench because their synthetic ...

Improving the accuracy of atom interferometers with ultracold sources
New Journal of Physics, 2018 We report on the implementation of ultracold atoms as a source in a state of the art atom gravimeter. We perform gravity measurements with 10 nm s ^−2 statistical uncertainties in a so-far largely unexplored temperature range for such a high accuracy ...
