Upscaling the Fabrication of Rod‐Shaped Microgels: A Microfluidic Method Combining Step‐Emulsification With Consecutive Droplet Confinement in Parallelized Microchannels

Advanced Materials, EarlyView.
A microfluidic method is presented which enables parallelized fabrication of rod‐shaped microgels, based on step‐emulsification (SE) droplet generation and subsequent droplet distribution and confinement, combined in a single device. Microgel rods are fabricated in parallel at different flow rates based on two light‐mediated crosslinking chemistries ...

A Review on Submersible Motors

Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2012
Petrol kuyularında ve tarımsal sulamalarda yaygın olarak kullanılan dalgıç asenkron motorlar, tasarımı ve özellikleri bakımından normal asenkron motorlara çok benzemektedir. Bu motorların, yüksek akım yoğunluğu ile çalışması, boylarının uzun olması ve su ile soğutulması önemli özellikleri olarak sıralanabilir.

Photoacoustic Nanotagging for In Vivo Tracking and Optimization of Macrophage Immunotherapy in Solid Tumors

Advanced Materials, EarlyView.
Macrophage‐based immunotherapy for solid tumors is limited by poor tracking of cell localization and persistence. This study introduces nanotagged macrophages enabling near‐infrared photoacoustic imaging for real‐time monitoring. IFNγ‐conjugated tags enhance antitumor polarization without harming viability.

Development and research of a full-order observer for the dynamic system «cable line – permanent magnet synchronous motor» in discrete time

Известия Томского политехнического университета: Инжиниринг георесурсов
Relevance. Currently, the share of centrifugal electric pumps operating in intermittent modes is increasing, allowing for increased oil production from low- and medium-flow wells. This is achieved by switching the well to two-position control modes with
