The social media giant said Tuesday it’s created a team, known as New Product Experimentation, to design, build and launch apps that give people “entirely new experiences for building community.” The apps could range from games to business tools. Facebook is housing the team in a new limited liability company, the NPE Team. The structure will encourage more experimentation, allowing employees to quickly alter apps or even shut them down if they fail to live up to expectations, Facebook said.The new apps will include the developer name, “NPE Team from Facebook.” Some apps could be free, while others might offer in-app purchases, Facebook said. Apps are expected to hit Apple’s App Store and the Google Play store, as well as the web, in the coming weeks.”Oftentimes starting small is the best way to make the biggest discoveries,” the company said on the NPE Team website. “We believe building without fear of failure is the only way to achieve success.”The creation of the new team highlights Facebook’s efforts to develop features and services outside of its main social network, which has been embroiled in a series of privacy and security scandals and struggles to attract teens in the US. Outside of its main service and its Messenger app, Facebook has failed to develop popular apps on its own. The social network purchased the Instagram photo-sharing app and the WhatsApp messaging service. The company also successfully copied Snapchat’s Stories feature, allowing users to post videos and photos that vanish within 24 hours.

(The… Apps developed by the NPE team might serve as a proving ground for Facebook, giving the social network a sense of what features excite its 2.38 billion monthly active users, many of whom are wary of change, before the company invests heavily in them. It could also help Facebook create a market for its planned Libra cryptocurrency, which it’s launching with partners in 2020, if it’s integrated as a payment method for in-app upgrades. Facebook is building a digital wallet for storing the currency and said it’s too soon to tell if new apps will accept Libra. It’s an open question whether the standalone strategy will work. For two years, Facebook ran a startup-like initiative called Creative Labs that encouraged employees to experiment. It created the news-reading app Paper, ephemeral messaging service Slingshot and group messaging app Rooms. None of those services gained traction with users and Facebook shuttered those apps. The social network quietly wound down the informal effort in 2015. Separately, Facebook launched a TikTok competitor called Lasso, but the app hasn’t caught on with teens.”It is not a slam dunk that (Facebook) can come up with apps that drive new services,” said Tim Bajarin, president of Creative Strategies. “That will take a real understanding of the specific type of customer they want to reach and how well it is designed and executed.”NPE apps may not be distributed widely, Facebook said, and some would be limited to certain countries depending on the service. Facebook wouldn’t say how large the NPE team will be or who will oversee the group. The team includes smaller groups made up of engineers, product managers and designers. It will sit within the organization overseen by Facebook Chief Technology Officer Mike Schroepfer.Facebook said data collection will vary depending on the app. Some apps could allow users to sign in through their Facebook accounts. The social network already collects troves of information on its users, which businesses use to target advertising. The Federal Trade Commission is investigating Facebook after revelations surfaced that UK political consultancy Cambridge Analytica harvested the data of up to 87 million users without their permission. Facebook’s terms of service and data policy will apply to the apps released by the NPE team. The company will also be releasing “supplemental terms” for the team in the coming weeks before the new apps launch. Comment 1 Mobile Tech Industry Facebook 5:51

One of the first reaction mechanisms students learn in undergraduate organic chemistry is the SN2 reaction. Named because it involves the collision of two molecules, its energy barrier is related to the nucleophile, the solvent, and the leaving group. Exactly how the leaving group influences what is going on at the molecular level, however, remains elusive. © 2015 Phys.org Study reveals peculiar mechanism of radical addition-elimination Using reaction cross-beam scattering and velocity map imaging combined with simulation studies a gas-phase SN2 reaction, F- + CH3Cl-, and comparing it to prior studies of F- + CH3I, Martin Stei, Eduardo Carrascosa, Martin A. Kainz, Aditya H. Kelkar, Jennifer Meyer, Istvan Szabo, Gabor Czako, and Roland Wester from the Institute for Ion Physics and Applied Physics, Universitat Innsbruck in Austria, the Institute of Chemistry, Eotvos University in Hungary, and the University of Szeged in Hungary have determined that the leaving group has a strong influence on reaction dynamics by influencing the orientation of the reactants. Specifically, they found that while both the chlorine and iodine reactions form a hydrogen bonding complex at the entrance channel, key differences cause one to be a direct rebound mechanism while the other is an indirect mechanism. Their work is reported in Nature Chemistry.Reaction dynamics is the study of individual molecular collisions. While kinetic theory describes a mechanism based on aggregate behavior, reaction dynamics looks at individual particles. Reaction dynamics answers questions such as “Do the reactants need to collide in a certain way in order for a reaction to occur?” To answer questions about particular collisions, reaction dynamics studies must be conducted in the gas phase. This particular study looked at collisions using ion beams to control reactant velocity and TOF-MS to measure product velocity. In the SN2 reaction F- + CH3Cl- à CH3F + Cl-, fluorine serves as the nucleophile, which engages in a “nucleophilic attack” on CH3Cl, and chlorine serves as the leaving group. This reaction occurs through an orchestrated process that, on the molecular level, shows that fluorine must collide directly with the electrophilic carbon, rather than the chlorine or hydrogens. Lower velocities did indicate an indirect complex-mediated mechanism, but for most velocities, this reaction undergoes a direct rebound mechanism. This is evidenced from scattering data that shows the chlorine leaving scattering in the backward direction. Lower velocities showed isotropic scattering. Even though there is evidence of a hydrogen bonding complex at the entrance channel, this reaction is not a slow, complex-dependent mechanism. The hydrogen complex, however, may affect reactant orientation. This is not the case for the analogous reaction with iodine as a leaving group: F- + CH3I- à CH3F + I-. Prior studies showed that while this reaction does display some backscattering, it seems to have a greater isotropic distribution and higher internal energy at most velocities, indicating an indirect complex-mediated mechanism. For this reaction, the collinear entrance channel plays a more important role in lowering the reaction energy barrier than forming a hydrogen complex. In other words, the reactants may impact each other in various ways.Simulation studies confirmed the experimental results of the chlorine reaction. Additional simulation studies showed that mass differences do not play a role in the differences between these reactions mechanisms, and impact parameter measurements indicate that reactant orientation is much more efficient in the case of the chlorine reaction compared to the iodine reaction. This is likely due to CH3Cl having a larger dipole moment compared to CH3I, which causes the fluorine ion to preferentially impact CH3Cl in a direct rebound orientation.This study shows that given by comparing seemingly analogous gas-phase SN2 reactions, at the molecular level, their reaction dynamics are distinctly different. These differences are due to properties of the leaving group that are beyond differences in mass, and likely have to do with molecular orientation upon impact.

5 min read Growing a business sometimes requires thinking outside the box. Opinions expressed by Entrepreneur contributors are their own. The Scottish novelist and folklorist, Andrew Lang, died a century ago and couldn’t have known a thing about today’s vast array of analytics tools and metrics. Nonetheless, he presciently described how most businesses use that data when he wrote, “I shall try not to use statistics as a drunken man uses lamp-posts, for support rather than for illumination.”Decision-making based on data becomes more important with each passing day but gathering data and analyzing is altogether difference from knowing what to do with it. That’s why dashboards are so valuable for businesses. Here are five that every business should be consulting.Related: The 3 Dashboards You Must Have for Your Business Now1. Marketing dashboards. It is safe to claim that business is all about marketing. Nowhere is number visualization more important than in marketing and sales, so your marketing dashboard needs to show you all of these:Leads: Is your marketing working? This simple question is answered by the number of leads you’re getting. OK, I’ll give it to you – it’s not that simple. Rebecca Corliss lists 15 critical lead generation metrics that you need on your dashboard.Conversions: You make an offer (campaign). People see it (traffic). They register their interest (lead). Not all leads will convert. While you’ll measure all of the above, the important equation here is the lead-close rate (or conversion rate).Channel output: There’s a great advantage in using digital marketing dashboards that you which channels are working for your business and pinpoint ones that aren’t. Tie each channel’s contribution to your goals. Jettison non-responsive channels and plug the budget leak.Branding and engagement: When it comes to branding, things aren’t as straightforward as running a campaign, generating leads and persuading customers to buy. Since there are multiple touch points, you’d have to track changing customer profiles, their behavioral patterns, the route they take to get to the sale and the conversations they’re having. Brand equity is governed by these, so you need to watch closely.Online or offline, you just have to have a feel of your marketing pulse 24×7. An all-in-one marketing dashboard like Cyfe can give you an integrated view of your sales, customer data, web analytics, email and social media analytics.2. Finance and cash flow dashboards. Finance is the artery linking straight to the heart of every business. So is positive cash flow. Benjamin Shepherd argued that while financial accounts can be manipulated, the one true measure of the health of a business is its cash flow. If you don’t have your eyes on the money, you aren’t looking where you should.Web-based accounting solutions such as Xero and Freshbooks, and even larger enterprise-level solutions such as Intacct give you dashboards with analytics pulled in from finance, accounting, taxation and other monetary aspects of your business. Stay on top of those numbers.3. Project management dashboards. If it’s business, work must get done. Businesses of all sizes have projects of varying degrees, from one-off simple tasks to major operational endeavors. Project management is an undeniably important element of your business. Because it’s people you’ll be working with, every person comes with their own style of working. With multiple team members, it’d be a nightmare just to manage people and complete projects. That’s why you’d need a method that is systematized, accountable and easy.You can manage projects, tasks and deadlines using a variety of project management tools. Trello is one of the easiest ones to get started with. Most project collaboration tool dashboards now come with instant notifications, time tracking and other features.Related: Just Keeping Track of Key Measures Can Double Your Profits4. Human resources dashboards. People are critical to business growth and time is money, so you need a way to account for both. You can’t take all the time in the world to hire but, after they are hired, every team member is expected to be a star performer. How do you get to the bottom of this?How much time do you spend to source and attract talent? What methodologies are working for you? You won’t know a thing if you don’t pull out these insights from your hiring process. Big data has already made inroads into human resources, and “people analytics” is a “moneyball,” as Steven Pearlstein quipped in the Washington Post.OrgVue is a dashboard that brings in everything you need to know about your HR processes with powerful visualization, people data modeling, and custom-built databases.5. Customer support dashboards. Customer support is the last thing standing that helps you differentiate your business from competition. While it’s always about people, you still have to know how well you manage turn-around times, escalations requests, etc.Modern customer support solutions such as ZenDesk and Help Scout help you with analytics, dashboards and the necessary insights to streamline your customer service processes to make the leap to from customer service to customer delight.Related: New Google+ Dashboard Lets Businesses Manage Multiple Tasks in One Place Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global September 19, 2014 Register Now »
