Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Gourd‐Inspired Design of Unit Cell with Multiple Gradients for Physiological‐Range Pressure Sensing
Advanced Functional Materials, EarlyView.Gourd‐shaped micro‐dome arrays with coordinated modulus, conductivity, and geometric gradients co‐optimize sensitivity and linearity in piezoresistive tactile sensors. Under pressure, a solid upper dome embeds into a porous lower dome, triggering rapid contact‐area growth and series‐to‐parallel conduction, enabling unsaturated, intensity‐resolved ...

Complex evaluation of contracts for construction
Journal of Civil Engineering and Management, 2010 The effectiveness of construction processes largely depends on the effective contract preparation. To draw an effective contract for construction, the methods of assessment and comparison of these types of contract should be developed.

Construction, corruption, and developing countries [PDF]
The construction industry accounts for about one-third of gross capital formation. Governments have major roles as clients, regulators, and owners of construction companies.

Advanced Functional Materials, EarlyView.By mimicking the ion‐accelerating effect of ion channel receptors in neuron membranes, a biomaterials‐based ionic hydrogel (BIH) is developed, which offers a high ionic conductivity of 7.04 S m−1, outperforming conventional chitosan, cellulose, agarose, starch, and gelatin based ionic hydrogels.

Advanced Functional Materials, EarlyView.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

EX ANTE CONSTRUCTION COSTS IN THE EUROPEAN ROAD SECTOR: A COMPARISON OF PUBLIC-PRIVATE PARTNERSHIPS AND TRADITIONAL PUBLIC PROCUREMENT [PDF]
Theoretical literature suggests a variety of reasons why a public-private partnership (PPP)should exhibit higher costs of construction than traditionally procured public infrastructure projects.
