Genesis type of ore deposits indicated by trace elements of chalcopyrite
地质科技通报, 2023 Trace elements of metallic minerals are important to constrain the formation processes and genetic types of ore deposits. Trace elements have been mainly focused on pyrite, magnetite, and sphalerite but have rarely been applied to chalcopyrite. To reveal

Toward an overall analytical framework for the integrated sustainability assessment of the production and supply of raw materials and primary energy carriers [PDF]
, 2015 The sustainable production and supply of raw materials (nonenergy raw materials) and primary energy carriers (energy raw materials) is a core element of many policies. The natural resource base for their production and supply, and the access thereto, are

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins
FEBS Letters, EarlyView.We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

From Critical Raw Materials to Circular Raw Materials
ChemSusChemAbstractThis perspective addresses the key challenge of advancing the use of Critical Raw Materials (CRMs) and proposes a transition towards circular raw material management. In the context of our current economy, the unsustainable consumption, environmental degradation, geopolitical risks, and economic vulnerabilities associated with CRMs highlight ...

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
