Injectable Stimuli‐Responsive Amphiphilic Hydrogel for Rapid Hemostasis, Robust Tissue Adhesion, and Controlled Drug Delivery in Trauma and Surgical Care

open access: yesAdvanced Healthcare Materials, EarlyView.
Fast‐acting hydrogel seals bleeding wounds as the illustrated injectable, pH‐responsive network rapidly gels in situ to stop hemorrhage, adhere strongly to wet tissue, and release antibiotics in a controlled, pH‐dependent manner. The material withstands high pressures, shows excellent biocompatibility, and degrades safely, offering a versatile platform

Comparison of mechanical disturbance in soft sediments due to tickler‐chain SumWing trawl vs. electro‐fitted PulseWing trawl

open access: yesICES Journal of Marine Science, 2018
&NA; Tickler‐chain SumWing and electrode‐fitted PulseWing trawls were compared to assess seabed impacts. Multi‐beam echo sounder (MBES) bathymetry confirmed that the SumWing trawl tracks were consistently and uniformly deepened to 1.5 cm depth in ...

Ga‐on‐In Substitution with Zn Vacancies in Zn3In2S6 Induces Electron–Hole Asymmetry and In─O Bond Weakening for Coupled Two‐Electron Oxygen Reduction and H2O2 Stabilization

open access: yesAdvanced Materials, EarlyView.
Ga‐on‐In substitution coupled with Zn vacancies in Zn3In2S6 creates a dopantdefect synergy that weakens InO bonding and induces electronhole asymmetry. The resulting spatial charge separation directs the two‐electron oxygen reduction pathway, enabling efficient artificial photosynthesis of H2O2 with a production rate of 187.8 µmol g−1 min−1 ...

Estimation of Growth Parameters Using Length Frequency Data of Whiting (Merlangius merlangus euxinus, Nordmann 1840), from Black Sea Coasts of Turkey

open access: yesJournal of New Results in Science, 2020
: The growth parameters of whiting (M. merlangus euxinus, N. 1840) were estimated using length frequency data collected by trawl fishing in the Sinop region, Turkey during September 2009 to April 2010.

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

The Fish Funnel: A Trawl Modification to Reduce Fish Escapement [PDF]

open access: yes, 1989
In the Gulf of Mexico there is a need to assess the potential of underutilized fish resource stocks before a commercial fishery develops. Standard sampling trawls used in the Gulf are ineffective for sampling the resource, so larger, high opening, bottom

Overcoming Printing and Interfacial Challenges in Liquid Metal Direct Writing for Integrated Stretchable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Liquid metal direct writing is advanced from a technological and fundamental point. Utilizing a kinematic bed, printing on large surfaces with irregularities is enabled. Furthermore, a pressure‐driven flow during printing is discovered that affects the thickness of traces.

Quantum Electrometry of Non‐Volatile Space Charges in Diamond

open access: yesAdvanced Optical Materials, EarlyView.
Charges are generated when nitrogen vacancy qubits in diamond are illuminated by light. Transport and trapping in an electric field leads to the formation of large, stable space charge patterns that dynamically screen applied electric fields, impacting electric field sensing and photoelectric detection.
