On the design of lubricant free piston compressors [PDF]

, 2010
This thesis describes the development on long lifetime and an efficient piston compressor operating in a clean environment where oil lubrication must be excluded. Particularly in cooling systems including cryocoolers the presence of oil is a well known problem.

Two‐Handed Knot Tying Technique for Arthroscopic Surgeries

Arthroscopy Techniques, EarlyView.
Abstract Knot tying is a widely used and essential technique in arthroscopic tissue repair and fixation. Although it shows perceived simplicity, its technical complexity exceeds that of open surgery due to the challenges of suture fixation within confined intra‐articular spaces and demanding execution requirements.

Study of hydrogen injection strategy on fuel mixing characteristics of a free-piston engine

Case Studies in Thermal Engineering
The formation of the gas mixture in the cylinder has a significant effect on the combustion and emission of the engine. The main difference between a conventional engine and a free piston engine is that the piston movement mode is different. Therefore, a

Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

Carbon and Hydrogen, EarlyView.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

Chemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.

Characterization of a Ludwieg Tube with Free Piston Compression Heating in Mach 6 Configuration

, 2018
The free stream acoustic disturbance environment in hypersonic wind tunnel testing has a significant impact on boundary layer stability and transition to turbulence, and can influence the results of fluid-structure interaction studies.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Linear Generator for a Free Piston Stirling Engine [PDF]

Journal of Electrical and Electronics Engineering, 2014
In this paper we present some aspects about the design of a Stirling engine driven linear generator. There are summarised the main steps of the magnetic and electric calculations with application to a particular case of a cogeneration plant bassed on ...
