The Surface of the Eye
Drug delivery to the internal ocular structures remains an important and relevant topic owing to the unique immune privileges of the eye which limit the success of systemic injections. The need to prevent and/or treat several common conditions, including age-related macular degeneration, endophthalmitis, retinal degeneration, diabetic retinopathy, and cataracts, has motivated the development of pharmaceuticals that require entry into the eye and extended residency to be most effective. The ocular surface is a surprisingly diverse portion of the eye, consisting of multiple tissues and glands. From a diagnostic standpoint, ocular surface disease may appear on the inside of the eyelid, on the cornea, on the conjunctiva, and in any of the associated glands. The ocular surface also offers an attractive option for drug delivery due to its relative ease of application and minimally invasive approach.

Modern Small Farming and Homesteading: Automate and Simplify
Since the outbreak of COVID-19 pandemic, increasing number of people from the urban environment have moved to rural areas in search for more peaceful and healthier lifestyle. They do keep their city jobs, mostly working online, and aren't interested into agriculture besides limited production for their own needs. However, as they are accustomed to the use of ICT and electronics in everyday life, they would appreciate any device that would robotize, automate or simplify common jobs on property maintenance, which in turn would provide additional time for other activities. Despite the fact that the application of WSN and IoT in agriculture has been researched for 20 years, and although there has been a significant breakthrough in agricultural robotics, the automation of small farming machines is still scarce, which may prove to be the next new big thing for small equipment manufacturers and startups.

Dragon C2+
SpaceX COTS Demo Flight 2 (COTS 2), also known as Dragon C2+, was the second test-flight for SpaceX's uncrewed Cargo Dragon spacecraft, launched on the third flight of the company's two-stage Falcon 9 launch vehicle. The flight was performed under a funded agreement from NASA as the second Dragon demonstration mission in the Commercial Orbital Transportation Services (COTS) program. The purpose of the COTS program is to develop and demonstrate commercial sources for cargo re-supply of the International Space Station (ISS). The Dragon C2+ spacecraft was the first American vehicle to visit the ISS since the end of the Space Shuttle program. It was also the first commercial spacecraft to rendezvous and berth with another spacecraft. Initially, the objectives of the C2+ mission were to have been accomplished by two separate missions; Dragon C2 would have carried out a fly-by of the ISS, practiced rendezvous maneuvers and communications with the station, before returning to Earth. A second mission, Dragon C3, would have been the first mission to berth with the station. In July 2011, NASA gave tentative approval to combine the objectives of the two missions. In December 2011, NASA formally approved the merger of the COTS 2 and 3 missions into the Dragon C2+ flight. There were several launch delays, the last one occurring on 19 May 2012, due to a launch abort during the last second before liftoff. Dragon C2+ successfully launched from Cape Canaveral on 22 May 2012. During the mission's first three days all of the COTS 2 objectives were successfully completed. The mission's COTS 3 phase began on 25 May when Dragon rendezvoused again with the ISS and then was successfully captured using the Canadarm2. It was berthed to the station later that day, using the robotic arm. Dragon stayed for almost six days during which the astronauts unloaded cargo, and then reloaded Dragon with Earth-bound cargo. On 31 May, Dragon unberthed from the ISS, its capsule landed in the Pacific Ocean off the California coast and was recovered. All the objectives of the mission were successfully completed, and the Falcon 9-Dragon system became certified to start regular cargo delivery missions to the ISS under the Commercial Resupply Services program.

Ram Pickup
The Ram pickup (formerly the Dodge Ram pickup) is a full-size pickup truck manufactured by FCA US LLC (formerly Chrysler Group LLC) and marketed as of 2011 onwards under the Ram Trucks brand. The current fifth-generation Ram debuted at the 2018 North American International Auto Show in Detroit, Michigan in January of that year. Previously, Ram was part of the Dodge line of light trucks. The name Ram was first used in 1932–1954 Dodge Trucks, then returned on the redesigned 1981 Ram and Power Ram, following the retiring and rebadging of the Dodge D Series pickup trucks as well as B-series vans. Ram trucks have been named Motor Trend magazine's Truck of the Year six times; the second-generation Ram won the award in 1994, the third-generation Ram Heavy Duty won the award in 2003, the fourth-generation Ram Heavy Duty won in 2010 and the fourth-generation Ram 1500 won in 2013 and 2014, and the current fifth-generation Ram 1500 won in 2019.

Food Supply Chain Enchanced by Industry 5.0 Technologies
The consequences of a crisis for a society depend on the level of society preparedness for the crisis, infrastructure in place, and training and skills of people engaged. The technologies (e.g., IoE, CC, blockchain, AI, DT, and 6G) of Industry 5.0 are yet to be fully explored and exploited in ensuring the resilience and sustainability of food systems. Therefore, this research sketches out a complete concept of a food system using Industry 5.0 technologies, and the main focus has been given to the use of 6G, AI, blockchain, and digital twin (DT) at different processes from production to distribution and retail to help optimize the food supply chain and thwart any possible disruption thereof.

Cost-Effective Zinc–Iron Redox Flow Batteries
Zinc–iron redox flow batteries (ZIRFBs) possess intrinsic safety and stability and have low electrolyte cost. ZBRFB refers to an redox flow batterie (RFB) in which zinc is used as the electrochemically active substance in the electrolyte solutions. The zinc electrode has a reversible anode potential. Zinc ions are stable in both alkaline and acidic environments, even in a neutral electrolyte, and the electrochemical reaction rate is relatively fast.

External Horizontal Fixed Shading Devices
Solar protection is a passive strategy that directly influences thermal and visual comfort as well as heating, cooling, and lighting energy consumption of buildings. Using shading devices can produce some conflicts, such as the contradiction between winter requirements, summer comfort, and luminous comfort. This is why the shading device choice is a necessary issue for building design, especially in a hot and dry climate. Optimal solar protection must provide a maximum protection during the overheating period while permitting solar radiation penetration during the winter.
