Abstract Improving the thermal performance of building envelope and reducing energy consumption heat transfer are particularly important for conservation. Wall insulation materials can be divided into sintered non-sintered two types. Sintered wall have unique advantages in development self-insulating because their high strength, good ability wide range raw materials. In this paper, research sta...

Studies on the amino acid content of the cell wall of gram-positive bacteria have shown them to be composed of relatively few amino acids. One of the principal amino acids found in the cell wall of certain staphylococci is serine (1, 2, 5, 6). Although the optical configuration of staphylococcal cell wall serine has not been determined, Whitney and Grula (8) found that Micrococcus lysodeikticus...

The performance of phase change material (PCM) integrated building envelope in terms of peak load reduction, peak load time delay and thermal demand improvement was investigated for a prototype detached single family house in a hot climate location. Five market available PCM layers, which can be easily inserted into traditional wall construction, were selected and coupled into different walls a...

The article presents the results of studies concerning raw hemp shives obtained from Polish crop industrial as a loose-fill thermal insulation material. study focuses mainly on measurements pore size distribution, conductivity and air permeability An increase in value coefficient (0.049–0.052 W/(m·K)) was demonstrated with an bulk density. porosity individual pieces is 78.7% predominant number ...

The windings insulation of electrical machines will remain a topic that is updated frequently. The criteria severity requested by the electrical machine applications increases continuously. Manufacturers and designers are always confronted with new requirements or new criteria with enhanced performances. The most problematic requirements that will be investigated here are the extremely long lif...

In Slovakia, 35% of buildings are older than 50 years but most newer buildings built before 1990 have greater energy consumption. Some other countries also have similar problems. The growing importance of energy saving in buildings can be, in the case of new and old residential buildings (RB), achieved by lowering thermal energy consumption most often by application of polystyrene insulation on...

Packed-bed thermocline tank with sensible fillers is a cost-effective option for thermal energy storage (TES). In real charging and discharging, the stability disturbed expansion occurs due to various factors, leading decreased global performances of tank. The purpose this work experimentally numerically study impact inlet configuration insulation on in lab-scale under operating parameters. Fir...

original article   introduction: a practical solution which is sometimes efficient for noise control in the receiver locations is to enclose workers in an acoustic cabin. accordingly, prediction of the noise insulation performance is regarded as an important aspect of the design a personnel cabin. this study empirically aims to design an acoustic cabin using sandwich panels in a typical metal i...

Here, we report a nanopipette-based electrochemical approach to prepare metal nanoelectrodes with excellent control over electrode size, shape, and thickness of the insulation wall. Nanoelectrodes are prepared by electrochemical plating in a laser-pulled quartz nanopipette tip immersed in a liquid gallium/indium alloy electrode, which not only protects the ultrasmall quartz tip but also starts ...
