Protocol to develop a moisture-desorptive passive cooling system for electronics thermal management.

Passive thermal management with zero-energy consumption and high compactness has drawn increasing attention. Here, we present a protocol to develop a hygroscopic salt-loaded heat sink with a moisture-permeable membrane encapsulation technique for electronics cooling. We describe steps for preparing lithium bromide solution and heat sink with anti-corrosion graphene coating. We then detail procedures for preparing the hygroscopic salt-loaded membrane-encapsulated heat sinks (HSMHSs). The produced low-cost HSMHS exhibits remarkably high thermal management performance without the risks of leakage and corrosion. For complete details on the use and execution of this protocol, please refer to Sui et al.1.

Versatile Power-to-Water Battery for Energy Storage, Atmospheric Water Harvesting, and Humidity Control.

We present a novel power-to-water (P2W) battery that can store electricity as thermal energy and discharge it as a heat source for hygroscopic solution desorption. The battery can work in two scenarios: atmospheric water harvesting (AWH) and dehumidification. The involvement of high-grade energy and sophisticated design enables better sorption kinetics and storage density. A proof-of-concept prototype verified the feasibility and achieved a record-breaking water production rate of more than 10.2 g (Ldevice h)-1. Also, the battery can achieve a round-trip efficiency of 90% for AWH and 68% for dehumidification in large-scale storage. The inexpensive storage medium contributes to a very low cost per energy (∼20 $ kWh-1) which means that P2W batteries excel in short- and long-duration storage. The long-term transient performance studies demonstrate impressive competitiveness over the traditional AWH and vapor-compression dehumidification systems. P2W provides new directions for the development of versatile, scalable, repeatable, and sustainable energy storage systems.

[Nasal NK/T cell lymphoma: a report of 11 cases].

OBJECTIVE: To investigate the clinical diagnosis consideration of nasal NK/T cell lymphoma. METHOD: Reviewing the clinical data of 11 patients with nasal NK/T cell lymphoma between 1992 to 2003. RESULT: Eight patients were unilateral, 3 bilateral. Six patients were misdiagnosed of other diseases. Three were diagnosed correctly through pathological biopsy once. Eight patients died in 3 to 20 months. CONCLUSION: Nasal NK/T cell lymphoma is easily misdiagnosed. The right diagnosis can be built with clinical, pathological and imaging examination.
