Compact Layers of Hybrid Halide Perovskites Fabricated via the Aerosol Deposition Process : Uncoupling Material Synthesis and Layer Formation [PDF]
, 2016 We present the successful fabrication of CH3NH3PbI3 perovskite layers by the aerosol deposition method (ADM). The layers show high structural purity and compactness, thus making them suitable for application in perovskite-based optoelectronic devices. By

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Valorization of paper sludge for bioethanol and biogas production
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...

Wood wasp inspired space and earth drill [PDF]
, 2010 In this chapter, we explain why the low gravity encountered on Mars or on the Moon and the low mass of the probes, landers and rovers that carry drilling devices limit classical drilling techniques.

British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

TURKISH JOURNAL OF PHYSICS, 2019 Results of known experimental and computed studies of conditions for water hammers (WHs) in reactor pressurizers are analyzed. It is found that when emergency opening of pilot-operated safety valves of the pressurizers of nuclear reactors happens, WHs can be generated on pressurizer elements, and amplitudes of hydrodynamic load pulses significantly ...

Drill/borescope System for the Mars Polar Pathfinder [PDF]
The primary goals of the Mars Polar Pathfinder (MPP) Discovery Mission are to characterize the composition and structure of Mars' north polar ice cap, and to determine whether a climate record may be preserved in layers of ice and dust.

Exploring the Micro-Structure of the Proton: from Form Factors to DVCS [PDF]
, 2002 For a long time people made the mistake of thinking the proton was understood. New experiments, ranging from form factors to deeply virtual Compton scattering, promise a new era of highly informative studies.

Effect of the additive concentration on the modification of petroleum coke and anode quality
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...
