Tokyo, Japan (SPX) Aug 01, 2025






In a serious stride for solar-driven gasoline era, scientists from the Institute of Science Tokyo have engineered a nanoscale, porous photocatalyst that dramatically boosts hydrogen manufacturing from water and carbon dioxide conversion into formic acid utilizing daylight. The novel material-Pb2Ti2O5.4F1.2 (PTOF)-demonstrated roughly 60 occasions the exercise of beforehand reported oxyhalide photocatalysts.



Photocatalysts allow using daylight to drive chemical reactions. Upon absorbing gentle, they produce electrons and holes, which then provoke reactions resembling hydrogen manufacturing and CO2 conversion. PTOF stands out amongst these supplies as a result of its capability to soak up seen gentle and its resistance to oxidative degradation.



Led by Professors Kazuhiko Maeda of Science Tokyo and Osamu Ishitani of Hiroshima College, the analysis staff created extremely porous PTOF nanoparticles utilizing a microwave-assisted hydrothermal course of. Revealed on-line July 09, 2025 and within the July 18 challenge of ACS Catalysis, their work gives a blueprint for scalable, inexperienced photocatalytic materials design.



“The synthesis technique established on this examine permits world-leading photocatalytic efficiency for H2 manufacturing and the conversion of CO2 into formic acid amongst oxyhalide photocatalysts, utilizing an environmentally pleasant course of,” stated Maeda.



The important thing to their strategy lies in particle measurement and morphology management. By minimizing particle measurement, the staff diminished the journey distance for photogenerated cost carriers, decreasing recombination charges. In contrast to typical strategies that threat structural defects, their method preserved catalytic integrity.



The staff examined totally different water-soluble titanium complexes-based on citric, tartaric, and lactic acids-as titanium sources, alongside lead nitrate and potassium fluoride. The traditional titanium chloride precursor yielded bigger, much less porous particles (~0.5-1 um, floor space ~2.5 m2g-1), whereas the optimized technique produced nanoparticles beneath 100 nm with floor areas round 40 m2g-1.



Catalytic testing confirmed outstanding outcomes. Citric acid-derived PTOF achieved a sixtyfold improve in hydrogen manufacturing in comparison with the TiCl4-based pattern, with a quantum yield of 15% at 420 nm. For CO2-to-formic acid conversion, tartaric acid-derived PTOF reached a ten% quantum yield when mixed with a molecular ruthenium photocatalyst-both values setting new efficiency information for this class of supplies.



Regardless of their smaller measurement correlating with decrease cost mobility, the proximity of floor response websites enhanced total photocatalytic effectivity. This highlights how nanostructuring can overcome typical limitations in photocatalyst design.



The staff’s microwave-assisted synthesis gives a scalable, low-temperature pathway for fabricating high-performance photocatalysts. “This examine underscores the significance of controlling the morphology of oxyhalides to unlock their full potential as photocatalysts for synthetic photosynthesis. These findings are anticipated to considerably contribute to the event of revolutionary supplies that assist tackle international vitality challenges,” Maeda concluded.

swift – iOS BGTaskScheduler not working


I’m engaged on an App which shields some purposes, and when consumer achieves specific step rely, it unshields these apps.

My inspiration is that this beneath app. (Social Limits)
https://apps.apple.com/au/app/social-limits/id6471964510

My most important query is concerning BGTaskScheduler, Which isn’t working as meant. Its most important objective is to run periodically and test if consumer has achieved sure steps and unshields the app even when app is terminated or in background.

I’ve experimented with Social Limits app and I do know that it makes use of Background App Refresh to unshield the apps. (Examined this by revoking the permission and sees if it unblocks the app nevertheless it doesn’t with out this permission).

How can I obtain what Social restrict has achieved.

That is my code:

  BGTaskScheduler.shared.register(forTaskWithIdentifier: refreshTaskIdentifier, utilizing: nil) { job in
        self.handleAppRefresh(job: job as! BGAppRefreshTask)
    }

I name a perform to set the scheduler:

 scheduleAppRefresh()


non-public func scheduleAppRefresh() {
    //     MARK: - e -l objc -- (void)[[BGTaskScheduler sharedScheduler] _simulateLaunchForTaskWithIdentifier:@"com.take a look at.socialLimit.refreshTask"]
 //        BGTaskScheduler.shared.cancel(taskRequestWithIdentifier: refreshTaskIdentifier)
    BGTaskScheduler.shared.getPendingTaskRequests { requests in
        print("(requests.rely) BGTask Pending")
        
        guard requests.isEmpty else { return }
        
        let request = BGAppRefreshTaskRequest(identifier: self.refreshTaskIdentifier)
        request.earliestBeginDate = Date(timeIntervalSinceNow: 15 * 60) // Earliest 15 minutes later
        do {
            strive BGTaskScheduler.shared.submit(request)
            print("TASK SCHEDULE")
        } catch {
            print("Couldn't schedule app refresh: (error)")
        }
    }
}

That is my precise work dealing with perform:

    non-public func handleAppRefresh(job: BGAppRefreshTask) {
    scheduleAppRefresh() // Schedule the following refresh
    
    let queue = OperationQueue()
    queue.maxConcurrentOperationCount = 1
    
    let operation = BackgroundRefreshOperation()
    
    job.expirationHandler = {
        queue.cancelAllOperations()
    }
    
    operation.completionBlock = {
        job.setTaskCompleted(success: !operation.isCancelled)
    }
    
    queue.addOperation(operation)
}

The issue is it runs when debugging with command
e -l objc — (void)[[BGTaskScheduler sharedScheduler] _simulateLaunchForTaskWithIdentifier:@”com.take a look at.socialLimit.refreshTask”]

however would not work when app is on testFlight. I’ve even waited for twenty-four hours.

*** After 3 days of testing it ran simply 1 time.***

As a result of .searchable doesn’t permit for customizing buttons within the search bar, I’ve manually needed to recreate the search bar as proven under. Nevertheless, when eradicating one of many objects within the search bar, the TextField doesn’t resize appropriately and successfully inserts padding on the vanguard. When the TextField is targeted, it resizes and fills your entire area. If the “Compose” button was already hidden when the search bar is offered, it lays out appropriately. How do I resize the TextField after eradicating the “Compose” button robotically?

DOE publicizes web site choice for AI information facilities



“The DOE is positioned to steer on superior AI infrastructure because of its historic mandate and many years of experience in extreme-scale computing for mission-critical science and nationwide safety challenges,” he mentioned. “Nationwide labs are central hubs for advancing AI by offering researchers with unparalleled entry to exascale supercomputers and an enormous, interdisciplinary technical workforce.”

“The Division of Power is definitely a really logical selection to steer on superior AI information facilities in my view,” mentioned Wyatt Mayham, lead marketing consultant at Northwest AI, which focuses on enterprise AI integration. “They already function the nation’s strongest supercomputers. Frontier at Oak Ridge and Sierra at Lawrence Livermore usually are not experimental machines, they’re energetic methods that the DOE constructed and continues to handle.”

These labs have the bodily and technical capability to deal with the calls for of contemporary AI. Operating giant AI information facilities takes monumental electrical capability, subtle cooling methods, and the flexibility to handle excessive and variable energy hundreds. DOE labs have been dealing with that type of infrastructure for many years, says Mayham.

“DOE has already constructed a lot of the encircling ecosystem,” he says. “These nationwide labs don’t simply home huge machines. Additionally they preserve the software program, information pipelines, and analysis partnerships that preserve these machines helpful. NSF and Commerce play vital roles within the innovation system, however they don’t have the hands-on operational footprint the DOE has.”

And Tanmay Patange, founding father of AI R&D agency Fourslash, says the DOE’s longstanding experience in high-performance computing and power infrastructure immediately overlap with the calls for we now have seen from AI improvement in locations.

“And the inspiration the DOE has constructed is basically the precursor to trendy AI workloads that usually require gigawatts of dependable power,” he mentioned. “I feel it’s a strategic play, and I gained’t be stunned to see the DOE pair their ‘AI for science’ initiatives to speed up every little thing from battery supplies to fusion power within the days to come back.”

New Examine Reveals This Common Fruit Is Truly a “Superfood” – NanoApps Medical – Official web site


A brand new peer-reviewed article argues that grapes deserve a spot amongst right this moment’s prime superfoods.

A latest article revealed within the peer-reviewed Journal of Agriculture and Meals Chemistry takes a more in-depth take a look at the time period “superfoods” and presents a compelling argument that contemporary grapes deserve a prime spot amongst them. The creator, Dr. John M. Pezzuto, a distinguished professional in resveratrol and most cancers analysis and Dean of the School of Pharmacy and Well being Sciences at Western New England College, supplies an in depth overview supported by a variety of scientific proof.

In line with the article, the phrase “superfood” is extensively used however lacks an official scientific definition or standardized standards. Meals generally known as superfoods are sometimes a part of the Mediterranean Food plan and are sometimes full of pure plant-based compounds that assist general well being. Dr. Pezzuto first explores the broader panorama of what constitutes a superfood, then shifts focus to grapes, emphasizing that they’re incessantly missed in comparison with better-known choices like berries, regardless of providing related well being advantages.

A Advanced and Highly effective Fruit

Grapes are a pure supply of over 1,600 compounds, together with antioxidants and different polyphenols similar to flavonoids, anthocyanidins, catechins, phenolic acids, resveratrol, and extra. Polyphenols are credited with the well being advantages of grapes, by way of antioxidant exercise and influencing mobile processes. It’s the complete grape and the distinctive matrix of those compounds inside it that creates the organic results, not a single part.

Over sixty peer-reviewed research have been revealed within the scientific literature on grapes and well being. The function of grapes on cardiovascular well being is properly established, together with selling leisure of blood vessels and wholesome circulation, in addition to modulating levels of cholesterol.

Medical trials additionally present that grapes assist mind well being (assist keep wholesome mind metabolism and useful impacts on cognition), pores and skin well being (enhanced resistance to UV radiation and DNA harm in pores and skin cells), intestine well being (modulating the intestine microbiome and growing variety within the intestine), and eye well being (retinal affect by way of improve in macular pigment optical density).

Grapes and Nutrigenomics

Lastly, within the realm of nutrigenomics – the examine of meals on gene expression within the physique – grape consumption has been proven to positively alter gene expression in related physique techniques. Pezzuto means that it’s these actions on the genetic degree which might be doubtless the driving power behind the well being advantages of grapes.

“Dr. Pezzuto reveals that based mostly on the science, grapes are certainly a superfood, and ought to be acknowledged as such,” stated Ian LeMay, president of the California Desk Grape Fee, “and we’re hopeful that utilizing this nomenclature in affiliation with grapes turns into widespread apply. Fortunately, whether or not consumed for well being or sheer enjoyment as a wholesome snack, consuming California grapes is a win for customers.”
