KANAZAWA, Japan, Aug. 9, 2023 /PRNewswire/ — In a study recently published in the journal Nanoscale, researchers from Kanazawa University and AGC Inc. use three-dimensional atomic force microscopy to study the hydrated form and structure of commonly occurring oxide crystals.
While sapphire and quartz are oxide crystals used in a wide range of industrial applications, the atomic-scale structures of these materials are not well understood. The major chemical components of sapphire and quartz are aluminum oxide and silicon dioxide, respectively. These components have a high affinity for water, which affects the chemical reactivity of the crystals. Thus, a thorough knowledge of the water-binding properties of these oxides is important for further innovative applications.
To date, traditional microscopic methods have only provided insights into the two-dimensional topography of their surfaces. Now, a research team led by Keisuke Miyazawa from the NanoLSI at Kanazawa University has developed three-dimensional (3D) microscopy technique for a detailed study of the interaction of the surfaces of these materials with water.
The team started by looking at the surface structures and its hydration structures of sapphire and α-quartz in water. For this, they used an advanced form of microscopy known as 3D atomic force microscopy (3D-AFM). Oxide crystals usually have hydroxyl (OH) groups, which are the main “water-binding” molecules, closely linked with the oxides. Hence, the team studied the OH groups and its hydration structures on both crystals when immersed in water They found that the hydration layer on sapphire was not uniform because of the nonuniform local distributions of the surface OH groups. On the other hand, the hydration layer on α-quartz was uniform because of the atomically flat distributions of the surface OH groups.
When the interaction force of these oxides for water was subsequently measured, it was found that a greater force was required to break the water-crystal bonds in sapphire than in α-quartz. Lastly, it was also discovered that this affinity was much higher in regions where the oxides were in close proximity to the OH groups.
This study showed that the hydration structures of oxides are dependent on the location and density of OH groups, in addition to the hydrogen bonding (the chemical bond used to bind to water) strength of the OH groups. What’s more, it was successfully shown here that 3D-AFM can be used in unraveling the interaction of water with several surfaces, a potential avenue for understanding solid-liquid interactions better. “[T]his study contributes to the application of 3D-AFM in exploring atomic scale hydration structures on various surfaces, and hence, to a wide range of solid–liquid interfacial research fields,” conclude the researchers.
Background
3D atomic force microscopy (3D-AFM): AFM is an advanced form of microscopy wherein a sharp tip is mounted on a cantilever and follows the surface of a molecule. As it does so, the tip emits signals based on its movement, which helps identify the topography of the molecule. However, understanding the deeper structures of molecules requires a three-dimensional overview of their surfaces. Thus, researchers used a more advanced version of AFM in this study, which captured the structure of hydrated crystals in 3D.

CapitaLand Investment launches research paper on ‘Asia Pacific Data Centre Investment Strategies in the Age of Digitalisation’

Published

on

capitaland-investment-launches-research-paper-on-‘asia-pacific-data-centre-investment-strategies-in-the-age-of-digitalisation’

 Strong secular tailwinds drive investors’ interest in the region’s sector
SINGAPORE, July 5, 2024 /PRNewswire/ — CapitaLand Investment (CLI) has launched its latest research paper on investment strategies for Asia Pacific’s (APAC) data centre (DC) industry as part of its ‘Perspectives’ research series.  Leveraging insights from CLI’s expertise on the ground, the research paper highlights the demand drivers behind the rapid growth of DCs in the region and strategic investment considerations for investors. The paper also includes a case study on navigating India’s DC sector.

Ms Michelle Lee, CLI’s Managing Director, Private Funds (Data Centre), said: “Digitalisation is a global mega trend driving the growth of data centres. With the DC sector’s strong secular tailwinds, 97% of institutional investors plan to increase their capital allocation into the sector1, particularly in Asia Pacific. As DCs are more resilient, allocation to this asset class can be an integral part of investors’ portfolio diversification strategy.”
“CLI has accelerated our growth in the DC sector, adding 22 DCs since 2021. Today, we have 27 DCs with about US$4.5 billion assets under management and more than 800 megawatts (MW) in gross power across eight countries globally2.  CLI has vertically integrated DC capabilities spanning across design, development, sales, and operations. With DC domain capabilities, combined with our deep market knowledge, deal-sourcing and investment network in Asia, we are well-positioned to partner with investors to tap into the wealth of opportunities in the sector,” added Ms Lee.
APAC as a strong growth market
While cloud computing has been the primary driver for DC demand, the rise of artificial intelligence (AI) is now fuelling a more explosive growth. The revolution in the scale at which data is being used and managed is fundamentally a global phenomenon, but nowhere is it unfolding as rapidly as in APAC markets. On population per MW basis, APAC markets are underserved compared to regions such as EMEA and North America3.
APAC economies are not only growing faster, the region’s enormous population and swelling internet user base also cement its status as a highly attractive destination for DC investment. Its internet user base has grown seven-fold since 2005, compared to the growth of 1.9 times in the Americas and 1.8 times in Europe over the same period4. Going forward, APAC markets should continue to lead, as internet adoption further increases given the lower penetration rates in the region.
DC transactions in APAC rose about 2.4 times to approximately US$22 billion from 2019 to 2023, compared to the preceding five years, even as markets generally stagnated during the COVID-19 pandemic5.
While hyperscalers continue to drive DC demand, APAC colocation market is also expected to double in size to US$52 billion by 20266, becoming the world’s largest colocation DC market.
Key DC markets in APAC
Tokyo, Osaka, Seoul, Singapore and Sydney are key developed DC markets in APAC7. These markets have achieved scale and are important DC hubs in the region.
Beijing and Shanghai also show promise due to China’s large population, growing digital services sectors, strong government support, and robust long-term economic prospects. 
Increasing demand for DCs in India
Highlighting India as a hotspot for DC investment, Mr Sanjeev Dasgupta, CLI’s CEO for India, said: “India’s DC industry has seen increasing interest from institutional investors and has a long runway for further growth. India has the world’s second highest number of mobile subscribers and one of the fastest growing data consumption per user rates. The government’s digitalisation drive, data localisation regulation as well as the growth of cloud and AI will generate more demand for DC capacity. With CLI’s 30 years of experience in India, we have the capabilities and a deep understanding of the local market. We have a dedicated team of DC experts in India and are currently developing four DCs across the key markets of Mumbai, Bengaluru, Chennai and Hyderabad with a total gross power of 244 MW.”
The seven major cities in India – Mumbai, Bengaluru, Chennai, Hyderabad, Delhi NCR, Pune, and Kolkata – are the focal points for new DC development, offering strategic locations with proximity to key business centres. Mumbai stands out as the preeminent hub, hosting more than half of the country’s DC capacity8 with the other major cities mentioned developing strongly.
Opportunities and strategic considerations
Different DC models offer a spectrum of options for investors, catering to different preferences and risk appetites. However, the lack of stabilised DCs available for sale in APAC means the most promising opportunities for investors lie in developing new DCs – a strategy that can both satisfy new demand and yield higher returns.
Power availability has taken centre stage as a crucial determinant for DC locations. There is also a growing emphasis on sustainability. Increasingly, DC users and savvy operators are seeking to reduce their carbon footprints by being more energy-efficient and tapping renewable energy sources.
Investors should also be mindful of the geopolitical, regulatory and technological risks associated with DC investments. It is therefore crucial for investors to collaborate with DC partners who have a strong network, local expertise, and specialist domain knowledge.
