THE EFFECT OF VARIATION CONCRETE CUBE OF AXIAL LOAD ON ULTRASONIC PULSE VELOCITY TRANSMITTER
Journal of the Civil Engineering Forum, 2015 Nowadays, Non Destructive Tests have been applied in some quality evaluation of existing concretes on site. One of the Non Destructive Test (NDT) methods is the application of the Ultrasonic Pulse Velocity (UPV) method. In general, utilizations of UPV as

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion
Advanced Materials, EarlyView.We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups
Advanced Materials Technologies, EarlyView.Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control
Advanced Materials Technologies, EarlyView.A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2010 Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. Sintering is a process which occurs
