This chapter discusses recent trends and advances of mesoporous molecular sieve in catalysis and also highlights the potential of these catalysts particularly in the field of organic reactions, which properly modified mesoporous catalysts are capable to catalyze. Successful synthesis of mesoporous molecular sieves has opened a new fascinating research area in inorganic chemistry strongly connected with organometallic chemistry and solid state chemistry and has potential applications in adsorption, drug delivery and catalysis. Mesoporous molecular sieves doubtless accelerated the development of new interesting catalysts in acid, base, and redox catalysis. In addition, large surface areas together with pore sizes in mesopore range enable the immobilization of highly active and selective homogeneous catalysts. Examples of mesoporous molecular sieves-involving acid-catalyzed reactions, hydrodesulfurization, metathesis, hydroxyalkylations, and C-C bond forming reactions (Heck reaction or Suzuki reaction) have been provided in the chapter. Activity of synthesized catalysts strongly depends on the type of mesoporous support under investigation, way of its modification, interaction of active species with the surface, and reaction conditions. Catalytic systems based on mesoporous silica or alumina supports modified with transition metal oxides for hydrodesulfurization (MoO3) and metathesis of olefins and unsaturated esters have also been discussed in this chapter. © 2009 Elsevier B.V.

And then to the content piece and wearables, going outside of smartphones, we of course expect smartphones for the foreseeable future to be people’s primary device. But where we’re making really strong progress is in areas like wearables, notebooks, and augmented realty, right? And so, in wearables and the notebooks, what we’ve done in both those areas is introduced using, our vapor deposition technologies, new composite materials that take our value on something like a wearable and a notebook up like a factor of five. And so, even outside smartphones, you see us playing the same basic approach, which is getting our new innovations adopted in those areas that also allow us to add value. Then you have entirely new device categories, like augmented reality, where you’re seeing the potential start to take shape for really significant innovation, and the vast new device category. But it’s soon, it’s too soon to get too excited about it. This is the time for all the positioning innovations and that’s something that years from now will offer a larger opportunity for us than what it is smartphones do today. But that’s gonna take a while to develop.
OUTLOOK ’17: US caustic soda to soar on alkali wings For US liquid caustic soda, historically a slow-growth, mature chemical commodity, 2017 is expected to be a growth year for US material. In fact, the forces that pushed US liquid caustic prices higher in 2016 are only expected to gain strength in 2017 and are likely to keep pushing well into 2018, according to a growing market consensus.
OUTLOOK ’17: Chemical stocks rally with US markets Many of the chemical stocks traded on US exchanges recovered from their lows reached in the early part of 2016 and approached their 52-week highs. ICIS follows more than 60 chemical, midstream and fertilizer stocks that are listed on various US stock exchanges. Out of these, several were close to their 52-week highs as of 9 December.
Modern Healthcare: Industry’s Strong Players Merging In Age Of Healthcare Disruption The prospect of another huge healthcare merger—this time involving two of Texas’ more prestigious hospital systems—is the surest signal yet that even the industry’s strongest players are having a difficult time navigating the rapidly shifting healthcare landscape. Baylor Scott & White Health, a dominant system in the Dallas market, and Memorial Hermann, which holds a similar position in Houston, hope to complete their combination by the middle of next year.

Acrylic acid derivatives are important raw materials for the manufacture of a wide variety of industrial and consumer products. In the theme of sustainability, more economical methods that utilize cheaper and less toxic feedstock are urgently needed. Clean pathways can be realized through the direct functionalization of CO2, which plays a dual role of reducing the CO2 emission rate and producing chemicals with added value. Because ethylene is one of the most abundant industrial feedstocks, manufacturing acrylic acid and acrylates directly from CO2 and ethylene becomes both scientifically fascinating and industrially relevant. As a dream reaction in catalysis and CO2 utilization, this challenging transformation has drawn close attention for nearly 40 years. With continuous efforts from both academia and industry, scientists are getting close to realizing an effective catalytic system. This review covers critical discoveries and discusses possible future directions in this area.

The Hill: To Improve Health Outcomes Federal And State Governments Must Collaborate The recent decision by Congress to direct Medicare reduction readmission penalties for hospitals that serve patient populations with high social needs is a step in the right direction, but it doesn’t go far enough. Certainly, easing up on readmission penalties is a positive development for struggling safety net hospitals, which have long (and correctly) voiced that their patients are more likely to experience complications after leaving the hospital through little fault of their own.

Superdry is now five months into its 18-month product diversification and innovation programme to broaden choice for its global consumers, which will address this reliance on heavier weight product. It is accelerating its expansion into lower participation categories (dresses, skirts, women’s tops and denim) and further extending into new market segments (premium, sport and licensed product ranges) while continuing to maintain strength in its core categories (sweats, jackets and T-shirts) through a focus on more relevant innovation.
OUTLOOK ’17: Brazil, Argentina to resume growing The recessions in South America’s two largest economies should end in 2017, while the prospects for Mexico will dim. Brazil should finally return to growth after two consecutive years in which GDP shrank by more than 3%. Argentina, South America’s second largest economy, should recover from the shock treatment of the reforms by its new president.
According to IHS Markit Process Economics Program (PEP) MMA reports, the two newer ethylene-based processes take different reaction routes to produce MMA. In the Lucite process, ethylene reacts with carbon monoxide and methanol to produce methyl propionate, which then reacts with formaldehyde to form MMA by removing water. In Evonik’s new LiMA process, ethylene reacts with hydrogen and carbon monoxide to produce propionaldehyde, which in turn reacts with formaldehyde to form methacrolein (MA) by removing water. MA further reacts with air and methanol to produce MMA.
