Brønsted and Lewis acid catalyzed conversion of pulp industry waste biomass to levulinic acid
(Department of Forest Biomaterials, North Carolina State University, 2019)
Enormous amounts of fiber sludge are generated annually by the pulp industry as a by-product. As a cellulose-rich material, its current usage, mainly as fuel, is inefficient from a material efficiency point of view. This ...
Building individual expertise in doctoral studies - the significance of everyday experiences and changing contexts
(Elsevier BV, 2015)
High expectations for skiils are directed at doctors and doctoral students in the fast changing global time. Innovative soiutions to the genuine
problems of society are expected of the new doctors. The expectations for ...
Building of the adult students' expertise and identity in the teacher's work which precedes the teacher education
(MAC Prague consulting Ltd., 2015)
This research describes adult students’ significant learning experiences in teacher’s work prior
to teacher studies. The research material comprises of 39 essays written by the students of

Business Cooperation - Improving The Working Life Relevance of Higher Education
(IEEE; Czech Technical University in Prague, 2021)
Education programmes should provide students with the skills for working life. This is important not only for students, but also for companies. Skills refers, in addition to competence in a specific area, to general ...
Carbons from second generation biomass as sustainable supports for catalytic systems
(Elsevier B.V., 2018)
In this study activated carbons were produced from the wood of three different wood species (pine, birch, spruce). The resulting activated carbons were characterized in bulk for ash content, carbon content (elemental ...

Catalytic conversion of glucose to 5-hydroxymethylfurfural over biomass-based activated carbon catalyst
(Elsevier BV, 2020)
Selective and efficient dehydration of glucose to 5-hydroxymethylfurfural (HMF) has been widely explored research problem recently, especially from the perspective of more sustainable heterogeneous catalysts. In this study, ...
Catalytic Effect of Transition Metals (Copper, Iron, and Nickel) on the Foaming and Properties of Sugar-Based Carbon Foams
(Springer, 2019)
Recently, bio-based carbon foams have gained much interest in many chemical industry felds because of their unique structure and properties. This study provides new information on the efects of catalytic metals (iron, ...
Characterization of Cobalt Catalysts on Biomass-Derived Carbon Supports
(Springer, 2017)
Cobalt catalysts are known to have a high activity and selectivity in the Fischer–Tropsch reaction converting synthesis gas to higher hydrocarbons (C5+). These catalysts have been supported by different porous materials. ...
Characterization of lignin enforced tannin/furanic foams
(Elsevier, 2020)
Worldwide, tons of lignin is produced annually in pulping plants and it is mainly considered as a waste material. Usually lignin is burned to produce energy for the pulping reactors. The production of value-added materials ...
