In conjunction with a single-cell sorting system, the target microorganisms identified by Raman spectroscopy can be sorted, sequenced, and cultured, facilitating microbial resource mining. Here, we summarize the methods for identifying, sorting and culturing plastic-degrading microorganisms using multidisciplinary technologies ( Table 1 ).

Pre-existing concealed goafs underneath open-pit slopes (PCO-goafs) pose a serious threat to the stability of open-pit slopes (OP-slopes), which is a common problem …

mining, process of extracting useful minerals from the surface of the Earth, including the seas.A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as …

Micro mining is a limited-capacity crypto mining activity that can be undertaken by frequently-used and connected Internet of Things (IoT) appliances, such as smart refrigerators, washing machines ...

In this paper, we present a data mining method to identify small subpopulations of cells that present highly specific expression profiles. This objective is formalized as a constrained …

Mining waste with micro-organisms to extract metals Companies are racing to capitalize on the ability to extract metals from tailings ponds Albert Van Santvoort Mar 25, 2023 2:00 PM

Innovation plays a critical role in the mining industry as a tool to improve the efficiency of its processes, to reduce costs, but also to meet the increasing social and environmental concerns among communities and authorities. Technological progress has also been crucial to allow the exploitation of new deposits in more complex scenarios: …

Moving toward a zero-carbon economy is an ambitious goal of all human beings. Utilization of various metal resources plays a central role in such a transition. Rare earth elements (REEs), especially heavy REEs (HREEs), are crucial for the development of future green and zero-carbon economies due to their irreplaceable roles in many …

Rubber Goods: Micro-Cel E is widely used in compounds where high oil loadings or other viscous liquid additions, including antioxidants, plasticizers, and adhesives, are required. Its use as a dry liquid concentrate carrier hastens the incorporation of the ingredient

Technical Description of CELITE MICRO-CEL E. Trade Grade: CELITE MICRO-CEL E. Trade Name: CELITE MICRO-CEL. Principal: Imerys. CAS Number: 1344-95-2. Group: …

Dockless electric scooters (E-Scooters) have emerged as a popular micro-mobility mode for urban transportation. This new form of mobility offers riders a flexible option for massive first-/last-mile trips. Despite the popularity, the limited regulations of E-Scooters raise numerous safety concerns a …

Stocks of -mined materials utilized in linear economic flows continue to present enormous challenges. E-waste is one of the fastest growing waste streams, and threatens to grow into a global problem of unmanageable proportions. An effective form of management of resource recycling and environmental improvement is available, in the …

Mining activities produce three different types of contaminants, i.e. wastes from mining and smelting deposited near their origin. This primarily includes waste rock, tailings, and slag. ... Use of yeast cell or dead bacteria was recommended to carry non-ionic surfactants as EOR slugs through the reservoir. This method was quite fruitful using ...

MicroCellClust identifies subpopulations in human breast cancer cells, namely (a) a subpopulation within CD4 T cells with marker genes related to GARP–Tregs, and (b) a subpopulation withing GARP+ Tregs with marker genes related to cell division.

Apple published a list of all its cobalt smelters, in line with international standards. Sony followed suit, publishing for the first time details of its cobalt supply chain. In August 2017, the DRC government admitted for the first time that children are working in cobalt mines. They pledged to end child mining by 2025 in their new strategy on ...
