A High-Efficiency Neutron Detector [PDF]

Nature, 1950
THE recent development of scintillation counters as high-efficiency detectors of gamma-radiation makes attractive the possibility of detecting neutrons by means of the γ-rays produced in many neutron-induced reactions. Particularly interesting is the detection of the 480-keV. γ-ray given off by the excited lithium-7 in the reaction:

Using Plasma Electrolytic Polishing for Post-Processing of Additively Manufactured Ti6Al4V Alloy Products

Technologies
One of the limitations of additive manufacturing technology is the high surface roughness of finished products caused by the layered structure of the deposition and the effect of adhesion of unfused powder particles.

High-Contrast OLEDs with High-Efficiency

, 2010
As more electronic devices with display are targeted for both indoor and outdoor uses (e.g. cameras, telephones, music players), it becomes increasingly important to solve the problem of contrast of the display under strong external lighting, more particularly under sunlight.

Psychosocial Functioning After Pediatric Bone Sarcoma: Generic and Survivor‐Specific Outcomes in Adolescent and Young Adult Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric bone sarcoma patients and survivors may experience psychosocial challenges related to childhood cancer after their intensive, body‐altering treatment. This cross‐sectional study aimed to evaluate generic and survivor‐specific psychosocial outcomes in a national cohort of pediatric bone sarcoma patients and survivors, and ...

Stiffness Modeling of Tooth Interior Fatigue and Tooth Flank Fracture and Their Fault Characteristics in Electromechanical Coupling Systems

Shock and Vibration
Tooth flank fracture (TFF) and tooth interior fatigue fracture (TIFF) usually occur on case-harden gears in electromechanical coupling systems, both starting from the core caused by metal fatigue. The cracks propagate rapidly compared with the total life

High Energy-Efficiency Buildings

, 2003
In cold, central European climates, hyper-insulated, heat-conserving buildings have proven a very effective way to reduce current energy consumption to 1/10 th of a traditional house. Using dry, stratified building techniques (Str/En) allows to obtain quite easily the required thermal and acoustical performances, also enhancing the construction process
