Introduction:Photography is a universal language that transcends barriers and connects people from different cultures and backgrounds. It has the remarkable ability to capture moments, evoke emotions, and tell stories without the need for words. In this essay, we will explore the profound impact of photographs, emphasizing the importance of preserving these visual narratives for future generations.Body:1. The Art of Storytelling:Photographs have the unique ability to tell stories in a way that words cannot. They freeze a moment in time,capturing emotions, expressions, and details that might otherwise be forgotten. Each photograph has a story to tell, and it is up to the viewer to interpret and appreciate the narrative behind it. By preserving these images, we ensure that these stories are not lost and can be shared withfuture generations.2. Historical Documentation:Photographs serve as valuable historical documents, providing a visual record of significant events, cultural practices, and societal changes. They enable us to revisit the past, offering insights into the lives of people who came before us. Without photographs, our understanding of history would be limited to written accounts, leaving out the visual context that adds depth and authenticity to our knowledge.3. Emotional Connection:Photographs have the power to evoke strong emotions and create a sense of connection with the subjects capturedwithin them. Whether it is a portrait, a landscape, or a candid shot, photographs have the ability to elicit empathy, joy, sadness, or even anger. They allow us to connect with people and places that we may never have the opportunity to encounter in person, fostering a sense of shared humanity.4. Cultural Preservation:Photographs play a crucial role in preserving cultural heritage. They capture traditions, customs, and ritualsthat might otherwise fade away with time. Through photographs, we can gain a deeper understanding and appreciation of diverse cultures, fostering respect and promoting cultural preservation. Preserving these images ensures that future generations can learn about and celebrate the rich tapestry of human culture.5. Reflection and Self-Discovery:Photographs not only capture external moments but also provide an opportunity for self-reflection and self-discovery. By examining photographs of ourselves and thosearound us, we gain insights into our own identities, relationships, and personal journeys. They serve as mirrors, allowing us to see ourselves from different perspectivesand encouraging introspection.6. Advocacy and Social Change:Photographs have long been used as a powerful tool for advocacy and social change. Iconic images such as "Tank Man" during the Tiananmen Square protests or "The Napalm Girl" during the Vietnam War have captured the attention of the world, raising awareness and inspiring action. Photographs can shed light on social injustices, humanrights violations, and environmental issues, compelling viewers to take a stand and work towards positive change.Conclusion:Photographs are more than just images; they are windows into the past, bridges between cultures, and catalysts for change. Preserving these visual narratives is essential for maintaining our collective memory, fostering empathy, andinspiring future generations. By appreciating the power of photographs, we can ensure that these captivating stories continue to be told, transcending language barriers and connecting us all.。

At a minimum thesewould include:a)Power cable to the input power connector or ethernet cable intoits portb)HDMI video display cable or Micro-B cable into the Console USBPortc)Keyboard and Mouse via USB (a hub may be required for multipledevices)d)MIPI Camera(s) or USB3 Type-C Camera (if applicable)e)M.2 2280 M-Key or M.2 2230 E-Key Module (if applicable)f)M.2 3042 B-Key Module (if applicable)5.Connect the Power Cable of the +12V Power Supply into the Barrel Jackor Power Over Ethernet capable switch to the Ethernet Port (NGX002Only).6.Plug the AC cable on the +12V Power Supply into the wall socket (thisdoes not apply to Power Over Ethernet). DO NOT power up your system by plugging in live power.POE PD AND GROUNDING DURING HOT PLUG EVENTSWhen powering the NGX002 through Power-over-Ethernet (PoE), the system or digital ground is created through an isolation transformer and has a floating ground point. This means there is a chance for the Photon’s digit al ground to be at a higher potential voltage than the externally powered devices ground reference. If an externally powered peripheral is plugged in while the Photon is live (hot-plugged) then the two ground points will try to equalize, with potential for a large ground current to be produced. This type of ground current event has the risk to cause damage to the connected peripherals or the interface connections of the Photon NGX002.Note that this applies only in the event of required hot plugging of the following interfaces:USB (P6, P13, J2), GPIO (P9) and HDMI (P12)If any of the above interfaces need to be hot plugged either within product operation or during installation/configuration, precautions must be taken and one of the following methods followed.1.Plug in all Externally Powered Equipment FirstPlug in and power all externally powered devices before applying power to the NGX002 via PoE (ethernet), connecting this as the last step. The common digital grounds between the interfaces will pull the ground reference of the Photon to the same potential before the unit has the chance to be powered. With Photons ground referenced to the externally powered devices ground, the opportunity of a ground current event should be eliminated.2.Switch Power Input to DC Barrel JackIf your application required the hot plugging of the USB, GPIO or HDMI interfaces, moving from PoE PD to barrel Jack DC barrel jack input will create a ground reference from the DC source that will likely mimic that of other powered equipment around it. (Photon, PC and Monitor all powered from same AC Power ground)e Peripheral IsolatorsAnother option when field service is required is to use HDMI and USB signal isolators.4.Create a System/Earth Ground ReferenceIf the above options are not suitable for your particular application, then the Photon should have its Frame Ground connected to a System or earth ground (eg, AC power ground, similar to that of the equipment being plugged in). The Frame ground connects to digital ground through a 10M resistor. Connecting this will bring the digital ground potential closer to the externally powered devices. For information on Frame ground locations see grounding notes below.Note: Rev F added an option to short the resistor out. It has been removed in Rev GNote: Rev G, with default connections, if user chassis is metallic and contacting any of the peripheral shells, the resistor will be shorted.GROUNDING NOTESThere are several resistors populated on the Photon that can be populated or depopulated to meet users grounding requirements. Please note that board level modification will void product warranty, if a particular grounding connection scheme will be required, please contact Connect Tech Support to discuss available options.Mounting HolesRevision A-F: The four (4) mounting holes are electrically isolatedRevision G: The mounting holes are connected to Frame GND through 0R resistors.Revision G connects the shells to digital ground by default. However, options exist for these to connect to frame ground or float depending on the required setup.Please contact for Connect Tech Support for further information. Or if a preconfigured grounding method isrequired,****************************.SOFTWARE SETUPPrior to hardware installation, ensure the correct software installed on the Jetson Module.

Editorial (Special Issue of Photocatalysis for Solar Fuels)
Preface to the Special Issue of Photocatalysis for Solar Fuels
As natural photosynthesis does, direct conversion of solar energy into the storable form of chemical energy is an intriguing technology for solar energy utilization. Due to increasing concerns of energy and environmental problems caused by the consumption of fossil fuels, production of chemical solar fuels (such as hydrogen, methanol or methane, etc) by artificial photosynthesis, namely photocatalytic splitting of water or reduction of CO2, has been a hot research topic in recent years.
As for the HER catalysts and reactions, Tierui Zhang and coworkers contributed their work on Sn2Nb2O7 nanocrystals, Yujie Xiong and coworkers on Au‐TiO2 plasmonic photocatalysts, Xinheng Li and coworkers on PdS‐CdSe@CdS‐Au nanorods, Xiaoxiang Xu and coworkers on Ti3+ modified anatase TiO2, Meiyin Liu and coworkers on Zn0.9Cd0.1S solid solution, Geng‐geng Luo and coworkers on fac‐ and mer‐tris(thiosemicarbazide) cobalt(III), Baojun Ma and coworkers on noble metal free phosphide/CdS composite
This special issue collects 23 papers, including three review papers. Liwu Zhang and coworkers reviewed enhancement of light absorption and utilization by photonic slow photons. Zhiliang Wang and coworkers reviewed recent progress in designing effective photoelectrodes for water splitting. Hongmei Yu and coworkers reviewed water electrolysis based on renewable energy for hydrogen production.
In order to efficiently convert solar energy into chemical energy of solar fuels, development of efficient photocatalysts and better understanding the fundamental photocatalytic reaction processes for water splitting and CO2 reduction are in highly demanding. To do so, appropriate light absorption photocatalysts (such as semiconductors), oxygen evolution catalysts (OER), hydrogen evolution catalysts (HER) and CO2 reduction catalysts, as well as the mechanism of energy conversion processes have to be extensively studied. Some recent research progresses in these aspects, mainly from China, have been collected in this special issue of photocatalysis for solar fuels.
