Strategies toward development of biodegradable hydrogels for biomedical applications
Hydrogel polymer tissue regeneration drug delivery encapsulation
2024/1/22
Hydrogel is a macromolecular gel constructed of a network of cross-linked polymer chains. Hydrogels are class of materials that can be tuned toward the subjected stimuli and can be modified to imitate...
Rosin-Based Si/P-Containing Flame Retardant Toward Enhanced Fire Safety Polyurethane Foam
bio-resource flame retardant rosin synergistic effect
2023/12/4
Environmentally friendly flame retardant such as polysiloxane has long been sought for varied studies in recent years and can be further improved to overcome the challenges of additional applications....
Modulation of interfacial interactions toward strong and tough cellulose nanofiber-based transparent thin films with antifogging feature
Cellulose nanofiber Transparent film Cross-linker Flexibility Toughness Antifogging
2023/12/1
Cross-linking is often performed to overcome the weak mechanical properties of native polymer films in order to expand their functional properties and applications. While this approach offers enhanced...
Uniform Pd0.33Ir0.67 nanoparticles supported on nitrogen-doped carbon with remarkable activity toward the alkaline hydrogen oxidation reaction
Alkalinity Anodes Binary alloys Carbon Cyclic voltammetry Density functional theory
2023/6/21
Highly efficient non-Pt electrocatalysts for the alkaline hydrogen oxidation reaction (HOR) are required to enable complete replacement of Pt in hydroxide exchange membrane fuel cells (HEMFCs). Herein...
In the film “Top Gun: Maverick,” Maverick, played by Tom Cruise, is charged with training young pilots to complete a seemingly impossible mission — to fly their jets deep into a rocky canyon, staying ...
Whether you are a new employee, a gymnast, or a bendy straw manufacturer, one trait is ideal across the board: flexibility.
What do the Apple watch and the Raptor engine of the SpaceX Starship have in common?
Electric cars – and their continued sales growth – are expected to have a greener, cleaner influence on air pollution and reduce human mortality in most, if not all, U.S. metropolitan areas, according...
With superconducting diodes, scholars advance work toward ultra-efficient quantum electronic devices（图）
超导二极管 量子电子器件 磁场
2023/6/26
A research team including Brown University faculty and students created a superconducting diode without a magnetic field in multi-layer graphene, a development that could form the basis for future “lo...
In the endless quest to pack more energy into batteries without increasing their weight or volume, one especially promising technology is the solid-state battery. In these batteries, the usual liquid ...
A heart attack patient, recently discharged from the hospital, is using a smartwatch to help monitor his electrocardiogram signals. The smartwatch may seem secure, but the neural network processing th...
Automated speech-recognition technology has become more common with the popularity of virtual assistants like Siri, but many of these systems only perform well with the most widely spoken of the world...
A quantum internet could be used to send un-hackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum netw...
To replenish groundwater, many municipalities inject reclaimed water into depleted aquifers. The injected water has been purified by secondary wastewater treatment, and, in some cases, has been treate...
Chemo-enzymatic pathways toward pinene-based renewable materials
Pinene-based renewable materials Sobrerol methacrylate SobMA
2024/3/8
Sobrerol methacrylate (SobMA) was synthesized and subsequently polymerized using different chemical and enzymatic routes. Sobrerol was enzymatically converted from α-pinene in a small model scale by a...
