Surface transformation hardening of carbon steel with high power fiber laser
(Lappeenranta University of Technology, 2013-01-09)
This study investigated the surface hardening of steels via experimental tests using a
multi-kilowatt fiber laser as the laser source. The influence of laser power and laser
power density on the hardening effect was ...
Identifying the opportunities to develop holistically sustainable bioenergy business
(Lappeenranta University of Technology, 2017-10-27)
Renewable energy solutions, of which bioenergy currently represents the largest share, are politically and scientifically considered to represent an indispensable replacement for the fossil fuel-based energy that is currently ...
Theoretical Analysis and Numerical Simulation of Spectral Radiative Properties of Combustion Gases in Oxy/Air-Fired Combustion Systems
(Lappeenranta University of Technology, 2012-12-11)
Energy efficiency is one of the major objectives which should be achieved in order to
implement the limited energy resources of the world in a sustainable way. Since radiative
heat transfer is the dominant heat transfer ...
Possibilities and challenges of longitudinal studies in operations management
(Lappeenranta University of Technology, 2011-12-19)
Longitudinal studies are quite rare in the area of Operations Management. One reason might
be the time needed to conduct such studies, and then the lack of experience and real-life
examples and results.
The aim of the ...
Polymer surface modification by atomic layer deposition
(Lappeenranta University of Technology, 2011-12-19)
Current industrial atomic layer deposition (ALD) processes are almost wholly confined to glass or silicon substrates. For many industrial applications, deposition on polymer substrates will be necessary. Current deposition ...
Chromatographic recovery of chemicals from acidic biomass hydrolysates
(Lappeenranta University of Technology, 2013-12-13)
Lignocellulosic biomasses (e.g., wood and straws) are a potential renewable source for the
production of a wide variety of chemicals that could be used to replace those currently
produced by petrochemical industry. This ...
Recovery of biomass-derived valuable compounds using chromatographic and membrane separations
(Lappeenranta University of Technology, 2013-12-12)
Utilization of biomass-based raw materials for the production of chemicals and materials is
gaining an increasing interest. Due to the complex nature of biomass, a major challenge in its
refining is the development of ...
Additional revenue opportunities in pulp mills and their impacts on the kraft process
(Lappeenranta University of Technology, 2013-12-18)
Although the concept of multi-products biorefinery provides an opportunity to meet the
future demands for biofuels, biomaterials or chemicals, it is not assured that its
implementation would improve the profitability of ...
Performance measurement and management in a collaborative network
(Lappeenranta University of Technology, 2013-11-15)
This study concerns performance measurement and management in a collaborative
network. Collaboration between companies has been increased in recent years due to the
turbulent operating environment. The literature shows ...
The accumulation of financial and social capital as a means to achieve a sustained competitive advantage for consumer co-operatives
(Lappeenranta University of Technology, 2013-12-12)
By so far, scholars have discussed how the characteristics of consumer co-operatives (cooperative
principles, values and the dual role of members as the users and owners) can
potentially give them a competitive advantage ...
