Lemons, or Squeezed for Resources? Information Symmetry and Asymmetric Resources in Biotechnology

Frontiers in Pharmacology, 2017
Thousands of biotech companies are developing promising products, but have insufficient resources to complete the clinical testing process, while large, well-funded companies have increasingly focused on the need to access external innovation.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Freeze-fracture Shadow-casting (FreSCa) Cryo-SEM as a Tool to Investigate the Wetting of Micro- and Nanoparticles at Liquid–Liquid Interfaces

CHIMIA, 2013
Since the seminal work of Pickering and Ramsden more than a century ago, adsorption of solid micro- and nanoparticles at the interface between two fluids has been recognized as a means to enormously improve emulsion stability against coalescence.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Visual Impact of High-Rise Buildings on the Surrounding Environment: A Case Study in Northern Cyprus

Proceedings of the International Conference of Contemporary Affairs in Architecture and Urbanism-ICCAUA
High-rise buildings represent modernity and economic power. Nevertheless, their abnormal scale and presence can alter and define the identity of the city.

Specters of ecocriticism

Przestrzenie Teorii, 2018
For years ecocriticism has been almost completely absent in Polish humanities, and although it has become known to a wider group of academics and literary critics and has gained some recognition, it is still not widely acknowledged. This situation raises

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

Advanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Tracking Systems for Orientation of Solar Panels and Optimization of their Positioning Using Three-coordinate Platforms [PDF]

Problems of the Regional Energetics, 2017
Two-coordinate platforms equipped with orientation systems are 40-45% more effective than stationary installations. However, there are other factors affecting the efficiency of solar installations.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
