As Science Evolves, How Can Science Policy?

Getting science policy right is a core objective of government that bears on scientific advance, economic growth, health, and longevity. Yet the process of science is changing. As science advances and knowledge accumulates, ensuing generations of innovators spend longer in training and become more narrowly expert, shifting key innovations (i) later in the life cycle and (ii) from solo researche...

Material Compositions Affects Vacuum System in Gripping Technology

Some grippers operate using Bernoulli Principle for generating a high-speed flow between the gripper plate and product surface thereby creating vacuum which lifted the product. Most of the robot grippers are not easily applicable due to the food products are often delicate, easily marked or bruised, adhesive and slippery. Feasibility observations are studied to demonstrate and obtain an overall...

ZnGeSb2: a promising thermoelectric material with tunable ultra-high conductivity.

First principles calculations predict the promising thermoelectric material ZnGeSb2 with a huge power factor (S2σ/τ) on the order of 3 × 1017 W m-1 K-2 s-1, due to the ultra-high electrical conductivity scaled by a relaxation time of around 8.5 × 1025 Ω-1 m-1 s-1, observed in its massive Dirac state. The observed electrical conductivity is higher than the well-established Dirac materials, and i...

Technology Evolves but Basic Ideas Survive

In 1994 four colleagues from different HE institutions in Norway started a collaborative R & D project for net based, open and flexible higher education. The project was named Norway-net with IT for Open Learning (NITOL), with focus on professional and institutional collaboration. Exchange and distribution of learning material through electronic networks were hard to implement in the pre-WWW da...
