Salman Khan and Disha Patani in Bharat song Slow Motion.YouTubeSalman Khan and Katrina Kaif’s recently released film Bharat has become the latest victim of online piracy as illegal notorious sites like TamilRockers have opened gates to download the full movie or online streaming for free. Directed by Ali Abbas Zafar, the movie stars an ensemble cast of Disha Patani, Jackie Shroff, Sunil Grover, Tabu and others apart from Salman and Katrina.The illegal sites have released Bharat full movie download links with 1080p or 720p HD quality prints from unofficial servers. The full movie download is likely to hit the film’s box office collection to a large extent.Some of the pirated copies seems to have been shot from a handy camera with average print quality while some have made HD quality prints available.However, this is not the first time a Bollywood movie has been hit by piracy. Earlier, movies like Simmba (Simba), Badhai Ho (Badhaai Ho), Thugs Of Hindustan (Thugs Of Hindostan), Zero, Race 3 and several other movies have also been leaked online which affected their overall box office performance at the domestic market.Bollywood industry has been trying hard to stop the piracy of films for the past several decades. Some filmmakers and producers with the help of cybersecurity forces have managed to block sites that allow online users to download the latest Bollywood movies that get released almost every week.The Union Cabinet, on February 6, had approved an amendment to the Cinematograph Act, 1952, to tackle the menace of film piracy and copyright infringement making penal provisions of a three-year jail term or Rs 10 lakh fine or both. The anti-camcording provision prohibits the illegal filming and recording of films in theatres.Though the film fraternity had rejoiced over the announcement, it seems like there hasn’t been any significant change or steps taken to curb and curtail piracy to prevent huge losses for the film industry. Bharat has opened to rave reviews from critics and audience alike and taken a flying start at the box office. The movie has collected Rs 42.30 crore on the opening day because of the immense buzz and strong word of mouth.
Multimaterial 3-D laser microprinting using an integrated microfluidic system Nematic liquid crystals (NLCs) are the simplest form of liquid crystal molecules without orderly positions, and they differentiate from pure liquids at the level of the molecular orientation. NLCs have a range of properties that allow them to serve as microreactors and conduct inherent polymerization reactions for intriguing future applications. Current work in the field is still experimental, for example, nematic flows in microfluidic environments, which highlight the potential cross-talk between topological defects in different fields of velocity and molecular orientation. In this work, the scientists observed the phase interface with NLCs for the first time, experimentally accomplished by generating polar-phase domains that were controlled by combining microfluidic confinement, fluid flow rates and laser pulses in practice. Emeršič et al. used the single-component nematic material pentyl-cyanobiphenyl (5CB) in all experiments performed in linear microfluidic channels with a rectangular cross-section. The scientists fabricated the channels with polydimethylsiloxane (PDMS) relief and indium tin oxide (ITO)-coated glass substrates using standard soft lithography procedures. They then filled the microfluidic channels with 5CB in its heated isotropic phase and allowed it to cool down to the nematic phase, before beginning the flow experiments. The scientists also chemically treated the microchannel walls to engineer a strong homeotropic surface to anchor the 5CB molecules. This document is subject to copyright.

Expansion and contraction of laser-nucleated dowser domains in a moderate nematic microflow. The lifetime of the domain is proportional to the critical velocity and the initial size.

(A) Schematic illustration of a channel with homeotropic anchoring on the top and bottom surfaces used in the experiment; IR, infrared; ITO, indium tin oxide. (B) The nematic in a channel looks black between crossed polarizers in the absence of flow and gains visible birefringence due to flow-driven director distortion that traps a domain of the flow-aligned state (also called the dowser state from here on); n denotes the nematic director. Strongly absorbed light of the laser tweezers heats the NLC, creating an isotropic (Iso) island that is quenched into the nematic (N) phase when the laser is switched off. The dense tangle of defects coarsens into a single defect loop that traps a flow-aligned dowser state, identifiable as a green area at low velocity. (C) The laser-induced nucleation of dowser domains can be automated and their shape can be dynamically controlled by tuning the flow parameters. Crossed double arrows indicate the orientation of the polarizers. White empty arrows in the bottom left corners indicate direction and qualitative velocity of the flow throughout the paper.

(A) Moving the laser beam transversely across the bulk dowser pinches off a uniform “train” of the domains. (B) A static beam at a low power of 80 mW generates a small isotropic region that cuts a large dowser domain longitudinally in half. (C) The shape and size of the domain can be maintained over long time and length scales by periodically modulating the driving pressure around the value that induces the desired average flow rate. (D) Under an alternating flow, a dowser domain reverses orientation every time the flow direction is changed. The reorientation creates surface point defects and realigning fronts, visible under the microscope as a rapid color change. The energetically unfavorable “old” orientation shrinks into a narrow 2π soliton and pinches the domain boundary (black arrows). (E) Sufficiently rapid flow reversal creates point defect pairs connected by solitons. With the flow turned off, the characteristic length goes to infinity, and the solitons expand, revealing their signature profile in transmitted light intensity (inset). In a slow residual flow, flow-aligned parts shrink more slowly than parts with unfavorable orientation. Scale bars, 20 μm.

They printed hydrophobic/hydrophilic domains on to liquid mixtures by relying on surfactant nanoparticles and controlled non-equilibrium systems to demonstrate the motion and transition between different rheological regimes. Liquid crystals (LCs) are an ideal system to study the phenomena of interest, such as spontaneous symmetry breaking, topological defects, orientation ordering and external stimuli based phase transitions.
