Application of Dust Explosion Protection Systems

open access: yes, 2014
Dust explosions have accounted for numerous deaths, disappearance of companies, and large financial losses, and yet they are one of the least recognized of industrial fire hazards.

Engineering Human Donor Derived Germinal Center‐Like Organoids (GCLOs) for Studying Immune Response to Vaccination

open access: yesAdvanced Science, EarlyView.
We bioengineered a new approach methodology of generating Germinal Center Organoids that self‐organize from human blood‐derived immune cells. These immune organoids reproduce key features of humoral immunity, IgG production, and plasmablast emergence.

The effect of selected inhibitors on the characteristics of wood dust explosion

open access: yesMATEC Web of Conferences, 2018
The mass concentration of four inhibitors which is required to suppress pine dust explosion were measured in laboratory-scale system. Measurements were conducted using four commercially available additives commonly used to decrease the fire and explosion

Challenges and enablers in fluidization technology

open access: yesAIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Effect of equilibrium relative humidity on explosion characteristics parameters of humid magnesium dust

open access: yesJournal of Magnesium and Alloys
In a humid environment, active metal magnesium is susceptible to the hydrogen evolution reaction with water, which significantly increases the risk of explosions in areas where magnesium is produced and used.

Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

open access: yesAdvanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Dust explosion hazards and prevention methods

open access: yes, 2012
W artykule tym dokonano analizy zagrożenia wybuchem stwarzanego przez pyły palne stosowane w zakładach przemysłowych. Opisano również kilka zaistniałych w przemyśle wybuchów mieszanin pyłowo-powietrznych.
