Experimental investigation of the effect of the powder and the suspension rheology on grindability

Geosciences and Engineering
The grindability of raw materials is a key parameter of mineral processing. It is also very important for some kinds of secondary raw materials, such as the demolition and construction wastes. The Institute of Raw Materials Preparation and Environmental Technology of the University of Miskolc has been dealing with this topic for a long time.

Multifunctional Adhesive Hydrogel for Rapid Cardiac Hemostasis and Antibacterial Protection

Advanced Materials Technologies, EarlyView.
A multifunctional polyacrylamide/gelatin/tannic acid hydrogel (PGT) is presented for rapid cardiac hemostasis under wet, dynamic conditions. Surface tannic acid coating enables instantaneous wet adhesion, accelerates coagulation, and confers antibacterial activity within a single platform.

Principles of polymer processing modelling

MATEC Web of Conferences, 2016
Polymer processing involves three thermo-mechanical stages: Plastication of solid polymer granules or powder to an homogeneous fluid which is shaped under pressure in moulds or dies and finally cooled and eventually drawn to obtain the final plastic part.

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays

Advanced Materials Technologies, EarlyView.
A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...
