The initiation of droplet and bubble formation on surfaces can now be directly imaged, allowing for design of more efficient condensers and boilers. — ScienceDaily

Nucleation is a ubiquitous phenomenon that governs the formation of both droplets and bubbles in systems used for condensation, desalination, water splitting, crystal growth, and many other important industrial processes. Now, for the first time, a new microscopy technique developed at MIT and elsewhere allows the process to be observed directly in detail, which could facilitate the design of improved, more efficient surfaces for a variety of such processes.

The innovation uses conventional scanning electron microscope equipment but adds a new processing technique that can increase the overall sensitivity by as much as tenfold and also improves contrast and resolution. Using this approach, the researchers were able to directly observe the spatial distribution of nucleation sites on a surface and track how that changed over time. The team then used this information to derive a precise mathematical description of the process and the variables controlling it.

The new technique could

Hong Kong, Singapore bubble delay highlights hurdles to travel recovery

SINGAPORE (Reuters) – A delay to Asia’s first travel bubble between Hong Kong and Singapore has hit the shares of their flag carriers and highlighted the challenges facing the global travel industry as it tries to rebound from the pandemic.

The arrangement was postponed on Saturday, one day before it was due to launch, after Hong Kong reported a jump in coronavirus cases. Authorities and aviation experts have said the bubble would provide a blueprint for quarantine-free travel before a vaccine is widely available.

“There is no doubt that there are many challenges around it,” said Singapore hotelier Marcus Hanna, who had taken bookings from Hong Kong tourists and hopes for similar arrangements with major markets like mainland

Hong Kong looks to mainland China for next air travel bubble

SINGAPORE — Hong Kong is hopeful its next “air travel bubble” could be with mainland China, the executive director of the city’s tourism board has said.

Dane Cheng told CNBC such plans would hinge on the success of the forthcoming Hong Kong-Singapore travel corridor. But he noted that adding a similar arrangement for quarantine-free travel around China’s Greater Bay Area would be the logical next step for business and leisure travelers.

“The next one for Hong Kong that we would like to see (would be) with the mainland, the Greater Bay Area,” Cheng said Friday.

The Greater Bay Area links several cities in Guangdong province with the special administrative territories of Hong Kong and Macao.

“That would be a key border for us,” he added, noting both proximity and common business and family ties.

Record stock rally faces risks from civil unrest, tech bubble

Big money managers are growing concerned that civil unrest could upend the stock market rally, but remain more worried about the impact of the COVID-19 pandemic, according to a Bank of America survey conducted in November.

A net 15% of respondents said civil unrest was the biggest “tail risk” to markets, trailing only COVID-19 (41%) and the tech bubble (19%). No respondents mentioned social upheaval as a concern in October’s survey.

The Charlotte-based lender surveyed 190 participants with $526 billion in assets under management between Nov. 6 and Nov. 12. The survey was conducted amid a resurgence in new COVID-19 cases and as the certification of the 2020 election hung in the balance following a flurry of lawsuits filed by the Trump campaign.
