  - Physicochemical Problems of Mineral Processing - Rok 2013

  Technologie szczelinowania wykorzystywane podczas wydobycia gazu z łupków zostały rozwinięte głównie w USA i są obecnie przystosowywane do warunków geologicznych i wymagań ekologicznych w innych państwach. Praca przedstawia literaturę na temat teoretycznych i praktycznych aspektów wydobycia gazu z łupków z naciskiem na technologie alternatywne do szczelinowania hydraulicznego. Rozpatrzono również techniczne i środowiskowe aspekty...

  • A. Rogala
  • J. Hupka

  - Physicochemical Problems of Mineral Processing - Rok 2015

  Shales have become one of the main unconventional gas resources in the world. However, physicochemical properties of rocks are still at the center of research. There have been conducted major researches in wettability of shales by fluids and advances in understanding and control of shale rock wettability. Also influence of interfacial phenomena on a production capacity of reservoirs have been made. The aim of this study is to find...

  - INORGANIC CHEMISTRY - Rok 2020

  Coordination complexes that possess large magnetic anisotropy (otherwise known as zero-field splitting, ZFS) have possible applications in the field of magnetic materials, including single molecule magnets (SMMs). Previous studies have explored the role of coordination number and geometry in controlling the magnetic anisotropy and SMM behavior of high-spin (S = 3/2) Co(II) complexes. Building upon these efforts, the present work...

• Possible application of new class of solvents in the purification of water used in hydraulic fracturing

  Publikacja

  • Z. Lustig

  - Rok 2012

  Nowym źródłem energii niekonwencjonalnej w Polsce może być gaz, który jest uwięziony w łupkach. Podczas poszukiwań gazu łupkowego, duże ilości wody wykorzystywanej w procesie szczelinowania hydraulicznego powracają na powierzchnię zanieczyszczone. Istnieje wiele metod usuwania śladowych ilości węglowodorów tj. fizyczne czyli filtracja czy chemiczne czyli zakwaszanie, ale mogą one być nieskuteczne. Pożądana metoda to monitorowanie...

• Microseismic Monitoring of Hydraulic Fracturing - Data Interpretation Methodology With an Example from Pomerania

  Publikacja

  • M. Antoszkiewicz

  • P. Szewczuk
  • R. Jankowski
  • M. Szkodo

  - Rok 2017

  Microseismic monitoring is a method for localizing fractures induced by hydraulic fracturing in search for shell gas. The data is collected from an array of geophones deployed on the surface or underground. Ground vibrations are recorded and analysed for fracture location, magnitude and breakage mechanism. For successful microseismic monitoring one need a velocity model of underlying formations. The model is further tuned with...

• Spatial distribution of CO2, O2, CO, NO and temperature within a biowaste composting pile

  Dane Badawcze

  open access

  • K. Sobieraj

  The dataset contains the color-coded isophlets illustrating the spatial distribution of gas concentrations (CO, CO2, O2 and NO) and the temperature in biowaste composting pile during 6 weeks of process. Four cross sections and two longitudinal cross sections (the left and right sides of the pile) were made using Surfer 10 software (Golden Software,...

  - INTERNATIONAL JOURNAL OF HYDROGEN ENERGY - Rok 2022

  To study the synergy between the transition metals for enhancing the electrochemical and chemical activity, a series of SOECs were modified with a small amount of Co ions, namely 1.8, 3.6, and 5.4 wt% in the reduced state. The addition of βCD into the precursor solution allowed for extremely fine dispersion of Co species across the Ni-YSZ cermet structure. The sample containing 3.6 wt% Co reached an outstanding over 2.5-times-higher...

• Diphosphination of CO2 and CS2 mediated by frustrated Lewis pairs - catalytic route to phosphanyl derivatives of formic and dithioformic acid

  Publikacja

  • N. Szynkiewicz
  • Ł. Ponikiewski
  • R. Grubba

  - CHEMICAL COMMUNICATIONS - Rok 2019

  The first example of CO2 diphosphination is described. Reactions of unsymmetrical diphosphanes with CE2 (E = O, S) catalyzed by BPh3 insert a CE2 molecule into the P-P bond with formation of the products of the general formula R2P-E-C(=E)-PR2. The obtained CO2 adducts arise from synergistic interaction of diphosphane and borane with CO2 molecule.
