Better Homes and Gardens has a new logo for the first time since 1965. Starting with its January 2017 issue, “and” is replaced with a stylized ampersand, and the long-standing three lines of text are truncated to two. The new identity system and refreshed logo, while aesthetically pleasing, also solves a practical issue, Stephen Orr, editor-in-chief since 2015, tells Folio:. Fitting the 51-year-old logo to digital avatars and brand extensions, like Better Home and Gardens Real Estate, has proven difficult. Now, the social avatar stacks “BH” over “&G” with white text inside of a black circle. This will replace the magazine’s current digital logo, a red background with “BHG” centered in a white, bolded, sans-serif font. Better Homes and Gardens is the largest brand at Meredith, and Meredith is the second largest consumer license brand in the world. This means the new logo will be seen on a lot of different products — from homeware sold at Walmart, to cookbooks, to real estate. The magazine also claims 40 million readers, with a verified rate base of 7,600,000 for its print issues. “They were really just thinking about the print magazine,” Orr says of the magazine’s mid-century editors. “But brands like BH&G are comprehensive brands. We needed something that was more flexible.” The new logo from January 2017 Due to the scale of use, the brand decided to partner with Lippincot, a creative agency that redesigned the Starbucks mermaid, as well as the Meredith corporate logo. The process took almost 10 months, Orr says, and involved over 75 different versions. The ampersand, while fresh in its design, is not new to the magazine. Better Homes and Gardens first launched in 1922 with “and” written out, but from 1931 until the late 40’s, the logo contained an ampersand along with its ever shifting typography. The old logo from December 2016
Mirza Fakhrul Islam Alamgir. File PhotoBNP secretary general Mirza Fakhrul Islam Alamgir on Tuesday said the next general election is a challenge for the Awami League, not for the principal opposition party.“This is because the people will not vote for the Awami League. And that’s why, the (AL) government is up to all sorts of mischief,” he told a press briefing at the BNP‘s Naya Paltan central office.The BNP leader pointed out that, angered by the misrule of the Awami League, the people of Bangladesh will take to the streets.“Then the house of cards will collapse. The people will bounce back (to restore their democratic rights) and this government will fall,” Mirza Fakhrul said after a meeting of the party to chalk out programmes on its founding day on 1 September.The BNP leader told a questioner that it is important that the media and the civil society play a key role in restoring fundamental rights of the people as well as to ensure free and fair elections in the country.He expressed his frustration at the censorship the media is dealt with nowadays. “The people will remember this,” he added.Mirza Fakhrul regretted that a section of critics said the BNP is in crisis. “The BNP cannot be ruined. This party has come here overcoming many odds… The next general elections, if held without participation of the BNP, will not be credible.”He also rejected out criticism that the opposition party does not announce programmes demanding the release of party chairperson Khaleda Zia.“Programmes are being announced and observed regularly. You will see at an opportune moment what kind of (other) programmes are announced.”The BNP’s senior joint secretary general Ruhul Kabir Rizvi announced the party’s programmes to mark the BNP’s founding anniversary on 1 September. The party held a joint meeting to finalise the programmes.According to UNB, the programmes include a public rally, discussions, hoisting party flags, and placing wreaths at the grave of party founder Ziaur Rahman.As per the founding anniversary programmes, the party flag will be hoisted atop its Nayapaltan central office and all other offices of BNP across the country at 6am on 1 September.Besides, the party leaders and activists will place wreaths and offer fateha at the grave of its founder ex-President Ziaur Rahman at 11.00am on the day.The BNP is scheduled to hold a rally at 3pm the same day either at Suhrawardy Udyan or in front of BNP office subject to permission by the authorities concerned.The party will also arrange a discussion at the Institution of Engineers, Bangladesh the following day.The party’s associate bodies and all of its units across the country will also mark the day with various programmes, including discussions.On 1 September 1978, late president Ziaur Rahman formed BNP with a 19-point programme to build a self-reliant Bangladesh. BNP ruled the country for several terms.

In a new study, engineers have designed a new device that can convert light of infrared (IR) and visible wavelengths into direct current by using surface plasmon excitations in a simple metal-insulator-metal (MIM) device. Explore further “SPs are excited by incident light when the photon and SP wave vectors match with each other,” Wang said. “For actual applications, it’s more realistic to use nano-grating patterns on one electrode to excite SPs. By simply controlling the pitches of these gratings, SPs can be excited at any specific wavelength. As a result, energy conversion efficiency could be enhanced in the optical band from infrared to visible.”The engineers calculated that these SP-enhanced MIM devices made with silver electrodes can achieve a power conversion efficiency as high as 4.3% for light with a 640-nm wavelength. Devices with gold electrodes have a maximum efficiency of 3.5% for light with a 780-nm wavelength. Both devices also have good theoretical efficiency across the entire solar spectrum – up to 2.7% for the silver-electrode device. The engineers also calculated that SPs can make silver devices almost 40 times more efficient than without the SPs for infrared light.In addition, the researchers fabricated a gold-alumina-gold device, with the top gold layer being slightly thicker than the bottom gold layer. Their experiments confirmed that light hitting the top layer excites SPs on the surface, which cause more hot electrons to be transmitted from the top to the bottom electrode. Although the resulting photocurrent that the researchers measured was smaller than the theoretical calculated value, they hope to increase the photocurrent in the future by using more effective coupling methods for SPs, optimizing metal thicknesses, and other strategies. Ultimately, the device could prove useful due to the wavelengths at which it operates.“It can work in the IR better [than other devices that convert light into DC], which can be used for energy scavenging,” Melosh said. The devices other advantages include easy fabrication and the possibility for being realized on flexible substrates.From now on, you can follow Physorg on Google+ too! Copyright 2011 PhysOrg.com.

This ability to maximize current from one electrode while minimizing it from the other is one of the biggest challenges for MIM devices. To do this, researchers can change the thicknesses of the electrodes. However, there is a tradeoff, since in a thicker electrode, more photons are absorbed but fewer electrons reach the interface due to increased scattering. Wang and Melosh’s solution is to use a prism to excite surface plamons (SPs) on the metal surface of the electrodes when under illumination. The SPs, which are small electron oscillations, can create a higher concentration of hot electrons in one electrode by efficiently coupling to light. The SP coupling efficiency depends on several factors, such as the thickness of the electrode, the type of metal used, and the wavelength of incoming light. More information: Fuming Wang and Nicholas A. Melosh. “Plasmonic Energy Collection through Hot Carrier Extraction.” Nano Letters, DOI: 10.1021/nl203196z The researchers, Fuming Wang and Nicholas A. Melosh of Stanford University, have published their study on the new device in a recent issue of Nano Letters.“The greatest significance thus far is to show an alternative method to rectennas and PV devices for IR and visible light conversion,” Melosh told PhysOrg.com. “The conversion efficiencies aren’t amazingly high compared to a PV in visible, so it’s not going to replace PVs, but it could be used for energy scavenging later on.”The new device’s MIM architecture is similar to that of a rectenna. However, whereas rectennas operate with long-wavelength light such as microwaves and radio waves, the new device operates with a broad spectrum of infrared to visible wavelengths. When the MIM device is illuminated, incoming photons are absorbed by the top and bottom metal electrodes. Upon absorption, each photon excites an electron in the metal into a higher energy state so that it becomes a “hot electron.” About half of the hot electrons travel toward the metal-insulator interface, where they may be collected by the other electrode. However, photon absorption in the upper and lower electrodes generates currents with opposite signs, so a net DC current is achieved only if the absorption is larger at one electrode than the other.
