Cadmium telluride (CdTe)-based cells have emerged as the leading commercialized thin film photovoltaic technology and has intrinsically better temperature coefficients, energy yield, degradation rates than Si technologies. More 30 GW peak (GWp) of CdTe-based modules are installed worldwide, multiple companies in production, shipping at up to 18.6% efficiency, lab cell efficiency is above 22%. We review developments science that occurred over approximately past decade. These achievements were...
The transition towards renewable energy requires increasing quantities of nonfuel mineral commodities, including tellurium used in certain photovoltaics. While demand for may increase markedly, the potential to supply is not well-understood. In this analysis, we estimate quantity contained anode slimes generated by electrolytic copper refining country between 1986 and 2018, uncertainties. For results indicate that 1930 (1500-2700, 95% confidence interval) metric tons were globally. This...
Mine tailings can host elevated concentrations of toxic metal(loid)s that represent a significant hazard to surrounding communities and ecosystems. Eolian transport, capable translocating small (micrometer-sized) particles, be the dominant mechanism metal dispersion in arid or semiarid landscapes. Human exposure metals then occur via direct inhalation ingestion particulates. The fact measured doses total lead (Pb) geomedia correlate poorly with blood Pb levels highlights need better resolve...
Environmental contextTellurium can be more toxic than arsenic, but its fate in the surficial environment is poorly understood. We studied tellurium behaviour semiarid mine tailings and found that most associated with iron (oxy)hydroxides as tellurate (TeVI), less oxidation state. Iron are likely to control of Te may effectively sequester oxyanions released by oxidative weathering. AbstractTellurium (Te) a critical element owing use solar technology. However, some forms highly toxic. Few...
Atomic chlorine (Cl•) affects air quality and atmospheric oxidizing capacity. Nitryl chloride (ClNO2) – a common Cl• source–forms when chloride-containing aerosols react with dinitrogen pentoxide (N2O5). A recent study showed that saline lakebed (playa) dust is an inland source of particulate (Cl–) generates high ClNO2. However, the underlying physiochemical factors responsible for observed yields are poorly understood. To elucidate these controlling factors, we utilized single particle bulk...
High concentrations of residual metal contaminants in mine tailings can be transported easily by wind and water, particularly when remain unvegetated for decades following mining cessation, as is the case semiarid landscapes. Understanding speciation mobility contaminant metal(loid)s, surficial tailings, essential to controlling their phytotoxicities revegetating impacted sites. In prior work, we showed that samples from Klondyke State Superfund Site (AZ, USA), ranging pH 5.4 2.6, represent...
This paper discusses two cases of linking formal and non-formal learning in science education. The concern education the Irish Transition Year, a facultative year between lower upper secondary education, laboratory environment for school students German university. Both are described, compared jointly reflected on education’s potential limitations supporting learning.
Public engagement in medicine has become more important promoting population health management and literacy. Medicine is a topic of great societal importance, many public activities have been developed to promote this area. However, they often narrowly focus on patient groups, diseases, singular pharmaceutical drug or analytical technique. Despite the importance these activities, general audiences are still heavily reliant doctors pharmacists for information about their lack basic knowledge...
A suite of complementary techniques was used to examine germanium (Ge), a byproduct critical element, and co-substituent trace elements in ZnS mine wastes from four mineral districts where is, or has been, produced within the United States. This contribution establishes comprehensive workflow for characterizing Ge other elements, which captures full heterogeneity samples through extensive pre-characterization. process proceeded optical microscopy, scanning electron microscopy...
Public engagement with science is a core facet of the broader ecosystem, in particular research and education sectors. In this article we demarcate benefits dedicated laboratories along practitioner advice pertaining to design running public learning environment. A practicing laboratory one that currently being developed are used as illustrative cases provide real-world insights practitioners.
Germanium (Ge) is a metal used in emerging energy technologies, communications, and defense, has been deemed critical by the United States due to its essential applications scarce supply. recovered as byproduct of zinc (Zn) sulfides, mining processing these materials lead waste that could act both source extractable Ge for exposure humans ecosystems. Yet distribution, speciation, mineral hosts mining-impacted areas are poorly understood. The Tar Creek Superfund Site, former Zn area producer,...
Incorporating research into undergraduate curricula, especially at an early stage, has been linked to improved critical thinking, intellectual independence, and student retention. This results in a graduating population more ready enter the workforce or graduate school. Similarly, mentoring enhanced self-efficacy, persistence, desire pursue studies. We have designed two courses that engage second-year students developing self-directed projects, proposal writing. These also serve nucleate...
The older layers of thick ferromanganese (FeMn) crusts from the central Pacific Ocean have undergone diagenetic phosphatization, during which carbonate fluorapatite (CFA) filled fractures and pore space replaced carbonates. effects phosphatization on individual trace metal concentrations, speciation, phase associations in FeMn remain poorly understood yet may be important to enrichment mechanisms, paleoceanography, extractive metallurgy. This study examines mineral Pb phosphatized...
Due to advances in EDS technology, electron microscopy techniques have become an important tool determine the relative abundance of mineral phases. However, few studies directly compared X‐ray mineralogy with traditional for assessing bulk and elemental composition. We show that analysing a limited area (~ 0.5–3.2 mm 2 ) fine‐grained metal extraction samples using principal component analysis phase mapping yields results agree within 10% more phases present at greater than 5% m / . Electron...
Designer drugs, like Spice, are synthetic psychoactive analogs of illegal substances with understudied health effects since they have traditionally been sold in packages labeled “not for human consumption” and the molecular structures can be specifically altered to circumvent legislation.

 The Diversity in Science towards Social Inclusion–Non-formal Education for Students’ (DiSSI) project aimed to provide a holistic perspective on diversity, focusing specifically cultural andethnic identities, language, socioeconomic background, gender, as well differing levels of achievement. In particular, the work presented this paper aims tackle consciously issues surrounding teaching andlearning socio-economically deprived areas through non-formal education. This presents results...
Approaches for inclusive science teaching currently tend to focus on only one dimension of diversity at a time. This neglects the fact that is multidimensional in nature, and consideration can yield practices with limited scope. Therefore, goal project "Diversity Science toward Social Inclusion─Non-formal Education Students' Diversity" (DiSSI) promote dealing several dimensions simultaneously non-formal education. Researchers from Ireland, Germany, United Kingdom, Slovenia, North Macedonia...
