Carbon Ink Enhanced Calcium Alginate-Based Hydrogel with Response Surface Methodology Optimized for Solar-Driven Salt-Tolerant Desalination.

The global shortage of freshwater resources is becoming more and more serious; therefore, it is necessary to obtain freshwater by desalinating seawater resources. Solar-driven interfacial photothermal evaporation, which is an environmentally friendly and energy-efficient technology, has been used to desalinate seawater for water purification and production. Herein, the IPCA hydrogel with abundant pores consisting of carbon ink as a photothermal conversion material and PU sponge loaded with calcium alginate as a water transport medium was successfully prepared and used to obtain portable water.

Green Synthesis of Polyurethane Sponge-Grafted Calcium Alginate with Carbon Ink Aerogel with High Water Vapor Harvesting Capacity for Solar-Driven All-Weather Atmospheric Water Harvesting.

Atmospheric water harvesting (AWH) technology is a new strategy for alleviating freshwater scarcity. Adsorbent materials with high hygroscopicity and high photothermal conversion efficiency are the key to AWH technology. Hence, in this study, a simple and large-scale preparation for a hygroscopic compound of polyurethane (PU) sponge-grafted calcium alginate (CA) with carbon ink (SCAC) was developed.

3-(Pyridin-4-yl-thio)-pentane-2,4-dione.

In the title compound, C(10)H(11)NO(2)S, the acetyl-acetone group crystallizes in the keto form with all the non-hydrogen atoms in the acetyl-acetone group approximately co-planar with a maximum atomic deviation 0.055 (2) Å; the dihedral angle between the acetyl-acetone group and the pyridine ring is 85.90 (6)°.

[The "wake-up correction" for preventing spinal cord injury in scoliosis surgery].

Objective: To observe the effects of "wake-up correction" technique for preventing iatrogenic spinal cord injury in scoliosis surgery.

Methods: Twenty-one patients who had scoliosis with Cobb's angle 92 degrees - 145 degrees received operation of pedicle screw insertion in all or important vertebral bodies, release of stiff segments, decompression and osteotomy. All the patients were trained how to wake up before anesthesia.
